Zis­mat­ic 40/08 WE

Effi­cient under­wa­ter pump for smal­ler garden water sup­plies

The Zis­mat­ic 40/08 WE com­ple­ments the SPECK product range of power­ful cistern pumps with an effi­cient vari­ant for the prob­lem-free rain­wa­ter sup­ply of smal­ler gar­dens with a power con­sump­tion of 0.55 kW and a deliv­ery rate of  2 m³/h at a pres­sure of 3 bar.

The cistern pump has an integ­rated, auto­mat­ic on/off switch mean­ing it can be eas­ily installed. It is sup­plied with a spring-loaded dia­phragm pres­sure ves­sel to pre­vent flut­ter switch­ing of the pump and to buf­fer small off-takes.

The Zis­mat­ic 40/08 WE is option­ally avail­able with a float­ing rain­wa­ter extrac­tion sys­tem. This reduces the amount of dirt being sucked in.

 

NTA grid dis­con­nec­tion sys­tems

Con­nec­tion-safe oper­a­tion on the drink­ing water net­work

In accord­ance with DIN EN 1717 “Pro­tec­tion of drink­ing water against con­tam­in­a­tion in drink­ing water install­a­tions” togeth­er with  DIN 1988-600 “Drink­ing  water  install­a­tions in con­nec­tion with fire extin­guish­ing and fire pro­tec­tion sys­tems”, the new sys­tems of the NTA A and NTA SFE series were developed for drink­ing water sep­ar­a­tion and sprink­ler sys­tems for under­ground hydrants.

The NTA grid dis­con­nec­tion sys­tems are avail­able for drink­ing water sys­tems and sprink­ler sys­tems includ­ing fre­quency con­trol up to a max. deliv­ery head of 50 m³/h. With a stor­age tank tested by DEKRA and cer­ti­fied by DVGW, the sys­tems with all built-in com­pon­ents are con­sidered safe for con­nec­tion to the drink­ing water grid.

Com­pact and light, the stor­age tank with a max. dia­met­er of 80 cm fits through any doorframe. A motor ball valve pro­tects the suc­tion line from pres­sure shocks. With 100 % inspec­tion of the sys­tem, SPECK offers a real care­free pack­age!

From the idea to the start of pro­duc­tion

Impulses for the new and fur­ther devel­op­ment of our products reach us in vari­ous ways, but nobody can avoid the tech­no­logy depart­ment. This is where indi­vidu­al cus­tom­er enquir­ies, feed­back from prac­tice, from the sales and pro­duc­tion teams, and new stand­ards and reg­u­la­tions flow togeth­er with our demands for qual­ity, energy effi­ciency and innov­at­ive strength. Here we design, test, meas­ure, eval­u­ate and optim­ise until an innov­at­ive idea turns into a product ready for pro­duc­tion.

In the 12-per­son team led by Sebasti­an Watolla, each col­league has found his spe­ci­al­ity. Dur­ing most pro­jects they work in teams, which are always reas­sembled accord­ing to the indi­vidu­al task. Extern­al com­pet­ences are also involved in some new devel­op­ments, such as the min­im­isa­tion of the sound pres­sure level of the BADU Delta Eco VS in cooper­a­tion with the Friedrich-Alex­an­der-Uni­ver­sity Erlan­gen-Nurem­berg.

Sebasti­an Watolla describes his team as a “healthy mix­ture of young and exper­i­enced”. Some col­leagues, like him­self, have been with SPECK Pumpen for almost 20 years and longer. Above all, they stand for the exper­i­ence that they share with  their  young­er  col­leagues  on a daily basis. These, in turn, bring new tech­nic­al know-how from schools and uni­ver­sit­ies to the devel­op­ment depart­ment. The long-stand­ing col­leagues are Jörg Dorn­busch, who has spe­cial­ised in elec­tron­ics and con­trol sys­tems; Thomas Kraus, who in addi­tion to CAD design is also respons­ible for trans­fer­ring data to the SPECK SELECT pump selec­tion pro­gramme; and Norbert Zie­g­ler, who has developed many pump types and counter swim units, such as the latest BADUJET Turbo Pro. Norbert will retire in spring 2020. To ensure a smooth trans­ition Thomas Moos­bur­ger has already been taken on as his suc­cessor. Both are cur­rently sampling and test­ing the BADUJET Turbo Pro hand in hand.

At the begin­ning of every devel­op­ment pro­ject, the tar­get has to be defined. This is the basis for the entire pro­ced­ure. If the product adap­tion con­cerns, for example, a spe­cial pumped medi­um, a mod­u­lar sys­tem can be used for all com­pon­ents that come into con­tact with the medi­um. Of course, exper­i­ence with a wide vari­ety of mater­i­als is also required.

For the new and fur­ther devel­op­ment of pumps, the hydraul­ic design by means of flow sim­u­la­tion is the focus. The flow qual­it­ies defined in the tar­get is the­or­et­ic­ally played through in a wide vari­ety of con­stel­la­tions. This res­ults in char­ac­ter­ist­ic curves and val­ues for effi­ciency and energy con­sump­tion, which are then eval­u­ated and com­pared with each oth­er. On this basis, the optim­al tech­nic­al solu­tion can be found with regard to many dif­fer­ent cri­ter­ia.

The new con­struc­tion of the com­pon­ents, as well as the adapt­a­tion of already exist­ing ones, is car­ried out by means of a CAD pro­gram. The parts are then prin­ted using a 3D print­er. The motor is either selec­ted from the range or newly developed in cooper­a­tion with a motor man­u­fac­turer. The res­ult­ing pro­to­type of a new pump now has to under­go numer­ous tests in the test labor­at­ory: Pres­sure tests, cycle tests, mould tests, elec­tric­al voltage tests and noise meas­ure­ments.

From the determ­ined val­ues, con­clu­sions can be drawn for the fine adjust­ment of the com­pon­ents until the res­ults agree with those the­or­et­ic­ally defined.

Once the pro­to­type has suc­cess­fully passed the test phase, the injec­tion moulds for new com­pon­ents are ordered. This is fol­lowed by the sampling phase, in which the first sample parts are meas­ured to the spe­cified tol­er­ances and sub­jec­ted to a func­tion­al check. Only then is the approv­al for series pro­duc­tion gran­ted by the tech­no­logy depart­ment.

How­ever, a pro­ject is then not yet com­plete. Jörg Dorn­busch coordin­ates and accom­pan­ies all neces­sary tests, e.g. for the GS sign. At the same time, the tech­nic­al input for oper­at­ing manu­als and parts lists has to be pre­pared and entered into the mer­chand­ise man­age­ment  sys­tem.  2D draw­ings and char­ac­ter­ist­ics are issued for cata­logues and bro­chures and the data for all pump types with­in a  series  are  entered  into  the SPECK SELECT pump selec­tion pro­gramme. Mean­while, the main design­er accom­pan­ies the ini­tial phase of pro­duc­tion intens­ively.

The Tech­nic­al Man­ager Sebasti­an Watolla is then able to present the new product to sales teams and rep­res­ent­at­ives at home and abroad and to present it at trade fairs. In his role he also acts as an inter­face to com­mu­nic­ate the innov­a­tions from the tech­no­logy depart­ment to the out­side world and to provide new input. As a mem­ber of the DIN com­mit­tee, he most recently helped devel­op the stand­ards for private swim­ming pool tech­no­logy and is now con­cerned with the impact of private swim­ming pool tech­no­logy on the envir­on­ment. This means that neither he nor his team will run out of ideas for fur­ther new and fur­ther devel­op­ments of SPECK pumps in the fore­see­able future …

Stain­less steel care

PRAC­TIC­AL TIPS FOR STAIN­LESS STEEL CARE

Lad­ders, stairs, rail­ings, handles, over­flow gut­ter grilles, showers and many oth­er com­pon­ents in or around the pool are made of stain­less steel. And for good reas­on: Vari­ous kinds of steel, which are com­monly referred to as “stain­less steel“, are par­tic­u­larly suit­able for use in this area due to their cor­ro­sion res­ist­ance. How­ever, stain­less steel also requires pro­fes­sion­al care to ensure last­ing res­ist­ance.

Stain­less steels are far more cor­ro­sion res­ist­ant than many oth­er metals. Through oxid­a­tion, the chro­mi­um com­pon­ent forms a pro­tect­ive film on its sur­face - the pass­ive lay­er. It devel­ops again and again through the effects of oxy­gen, even after dam­age, and pro­tects the com­pon­ent from neg­at­ive influ­ences. If this pro­tect­ive film can no longer form again, stain­less steel loses its rust res­ist­ance.

Dirt is depos­ited on stain­less steel in the swim­ming pool area and chlor­ides are accu­mu­lated, pre­vent­ing the form­a­tion of a new pass­ive lay­er. In the long run this leads to pit­ting or rust­ing. The com­pon­ents should there­fore be reg­u­larly cleaned of residues. On stain­less steel parts that are not con­stantly in con­tact with swim­ming pool water, you can remove depos­its with com­mer­cially avail­able stain­less steel clean­er and a cloth/sponge or rinse off with tap water. Do not use clean­ing agents con­tain­ing hydro­chlor­ic acid or chlor­ide and do not use metal­lic objects such as clean­ing pads or steel wool! The sur­faces of stain­less steel parts that lie under water can be cleaned by simply rub­bing them with no addit­ives.

In prin­ciple, all stain­less steel parts should be main­tained at reg­u­lar inter­vals. If the water qual­ity is unprob­lem­at­ic, it is suf­fi­cient to clean it twice a year. If your swim­ming pool is oper­ated at high tem­per­at­ures, the pH value of the water is very low or the swim­ming pool water con­tains salt, the installed stain­less steel parts should be cleaned at least once a month. For the first harm­less spots of cor­ro­sion, a slightly acid­ic spe­cial stain­less steel clean­er, avail­able from spe­cial­ist swim­ming pool deal­ers, can be used. Read the instruc­tions for use care­fully and rinse the stain­less steel parts with fresh water.

The prop­er remov­al of depos­its pre­vents rust form­a­tion on stain­less steel. The qual­ity of the sur­face plays an import­ant role: the smooth­er the stain­less steel, the easi­er it is to clean. We recom­mend elec­tro­pol­ished sur­faces for highly stressed com­pon­ents in swim­ming pools!

Proven auto­mat­ic back­wash sys­tem with new func­tions

AUTO­MAT­IC BACK­WASH UNIT

The swim­ming pool fil­ter sys­tem must be reg­u­larly back­washed. Filtered dirt is led into the sewage sys­tem and the fil­ter mater­i­al is loosened. This main­tains the water qual­ity and avoids rising energy costs due to increased fil­ter res­ist­ance. The pro­cess can be car­ried out manu­ally on manu­al back­wash valves or you can leave this neces­sity to our reli­able and time-sav­ing BADU Omni­Tron­ic. Since March 2019, the auto­mat­ic back­wash sys­tem offers a range of addi­tion­al func­tions for con­veni­ent pool oper­a­tion.

The BADU Omni­Tron­ic starts reg­u­lar fil­ter oper­a­tion daily at the same time and auto­mat­ic­ally car­ries out weekly back­wash­ing. An altern­at­ive oper­at­ing mode offers the pos­sib­il­ity of set­ting the times indi­vidu­ally for all oper­at­ing modes.

Since March 2019, back­wash­ing with the BADU Omni­Tron­ic has also been pos­sible at 6-hour inter­vals. Thus, it can also be used for example in koi carp ponds. A very short rinse time of only five seconds min­im­ises the water con­sump­tion.

Up to now, fil­ter con­trols, level con­trols or pres­sure switches could be integ­rated into the BADU Omni­Tron­ic. A pres­sure switch is offered as an option. The inform­a­tion can be trans­ferred spe­cific­ally to dos­ing sys­tems with the set­ting “FIL: P“. Since spring, the auto­mat­ic back­wash sys­tem is sup­plied with two addi­tion­al relays and now has even more poten­tial to per­form addi­tion­al func­tions.

The BADU Omni­Tron­ic can be used to couple the house heat­ing pump with the cir­cu­la­tion pump and thus con­trol the swim­ming pool water heat­ing. The tar­get tem­per­at­ure and oper­at­ing times for heat­ing oper­a­tion are adjustable. The same applies to swim­ming pool water heat­ing via sol­ar pan­els. The auto­mat­ic back­wash sys­tem con­trols the sol­ar sys­tem ball valve and locks when the set max­im­um tem­per­at­ure is reached. In the case of speed-con­trolled pumps, this can also be used to increase the speed for the oper­a­tion of sol­ar absorbers, which are usu­ally posi­tioned high­er up. In order to cool the pool if neces­sary, a heat exchanger can also be integ­rated into the auto­mat­ic sys­tem.

The two new relays offer the pos­sib­il­ity of integ­rat­ing house heat­ing and the sol­ar sys­tem in par­al­lel. The heat­ing ensures the desired min­im­um tem­per­at­ure and the sol­ar sys­tem also heats the pool water to the desired max­im­um value.

The frost pro­tec­tion set­ting is worth­while for out­door pools that are not emp­tied in winter. When a crit­ic­al tem­per­at­ure is reached, the cir­cu­la­tion mode is triggered in order to pre­vent the swim­ming pool water freez­ing.

Reli­able error out­put is now also pos­sible: Either an error mes­sage is sent to the mas­ter con­trol or a dir­ectly con­nec­ted sig­nal horn with light is activ­ated. If prob­lems occur, an acous­tic sig­nal sounds at a select­able inter­val.

The micro switch used to meas­ure the angle of the valve pos­i­tion has been replaced by a mag­net­ic angle sensor. Thus the exact pos­i­tion of the valve can be called up at tenths of a degree at any time. Fur­ther­more, main­ten­ance work no longer risks dam­age to the new com­pon­ent, as it can be eas­ily removed using plug­gable ter­min­als.

If the mech­an­ics of the BADU Omni­Tron­ic are over­loaded e.g. by con­sid­er­able con­tam­in­a­tion, the teeth of the small gear wheel can become deformed. A clat­ter­ing noise makes the dam­age aud­ible. This weak point pre­vents dam­age to high­er qual­ity parts and parts installed deep­er. Our emer­gency set con­tains a spare gear for this case. To replace it, simply loosen two screw con­nec­tions, remove the motor and replace the gear by pulling it off and plug­ging it on. Do not for­get to remove the cause (e.g. dirt) from the valve!

For 2020, we are already work­ing on an extern­al option: bat­tery pack + con­vert­er, which resets the valve to the fil­ter pos­i­tion in the event of a power fail­ure and thus pre­vents the pool from run­ning empty. In addi­tion, the devel­op­ment of a con­duct­ive sensor for level con­trol is also under­way. The elec­trode flow between two stain­less steel sensors can­not be mech­an­ic­ally blocked, as with pre­vi­ous float sys­tems. A con­duct­ive sensor avail­able on site is con­nec­ted to an addi­tion­al plug-in cir­cuit board that is already avail­able and can in future be integ­rated into the BADU Omni­Tron­ic. Fur­ther­more, the soft­ware will also be exten­ded for the con­nec­tion of a dry run pro­tec­tion (e.g. paddle switch) in auto­mat­ic mode.

New heat­ing pumps . INOVA NH II

One pump for all applic­a­tions

Just in time for the com­ing heat­ing sea­son, SPECK Pumpen is launch­ing a new series of heat­ing pumps to the mar­ket. The INOVA NH II, the suc­cessor to the INOVA NH, offers added value with a new design and addi­tion­al func­tions.

Three oper­at­ing modes are now avail­able for the dif­fer­ent applic­a­tions:

Vari­able dif­fer­en­tial pres­sure
The pump reduces the deliv­ery head by half with decreas­ing volume flow in the pipe net­work, e.g. for the oper­a­tion of con­ven­tion­al radi­at­ors.

Con­stant dif­fer­en­tial pres­sure
The con­trol keeps the set deliv­ery head con­stant regard­less of the volume flow, e.g. for the oper­a­tion of under­floor heat­ing sys­tems.

NEW: Fixed speed stage
The pump runs unreg­u­lated in one of three pre­set fixed speed stages, e.g. as a stor­age char­ging pump.

The new series cov­ers a per­form­ance range up to a max­im­um flow rate of 5 m³/h and up to a max­im­um head of 8 mWs. The effi­ciency-increas­ing thermal insu­la­tion shell is already included in the deliv­ery.

The INOVA NH II will be avail­able from autumn 2019.

Assembly BADU Easy­Fit con­nec­tions

We don’t only pro­duce high qual­ity products, we also offer a first class ser­vice. This includes our video tutori­als. In this video we will explain how to assemble the BADU Easy­Fit con­nec­tions.

Dur­ing assembly you should pay atten­tion to the cor­rect pos­i­tion­ing. The dis­tance between the edge and the open­ing is lar­ger on the bot­tom of the con­nec­tion than the top. Once the con­nec­tion has been attached cor­rectly, it can be fastened hand-tight using four screws. Using an elec­tric screw­driver will increase the risk of the con­nec­tion crack­ing.

Should you have any ques­tions or com­ments, please feel free to con­tact us.

Impress­ive water fea­ture

The Kem­p­in­ski Hotel Frank­furt has fol­lowed examples from Dubai and Las Vegas with an impress­ive water, light and sound spec­tacle. The water fea­tures are the attrac­tion for guests and vis­it­ors on the hotel‘s own lake. 116 SPECK pumps are behind the up to 30 m high foun­tains.

The man­age­ment of the Kem­p­in­ski Hotel Frank­furt Graven­bruch wanted the hotel com­plex to attract more vis­it­ors. Hotel, event and con­fer­ence guests should be as impressed as vis­it­ors to the res­taur­ants, bars, ter­races and well­ness area on the 15 hec­tare prop­erty.

This object­ive was achieved in sum­mer 2018 with a pro­gram­mable water show on the hotel‘s own lake. It is one of the few facil­it­ies of this kind put into oper­a­tion in a Ger­man hotel. The spec­tacle was inspired by the world-fam­ous Bel­la­gio foun­tains in Las Vegas and the Dubai foun­tain in the Burj Khal­ifa in Dubai.

With the excep­tion of the winter months, up to 116 col­our­ful foun­tains are reflec­ted on the 14,000 m² water sur­face of the lake every even­ing. They dance almost 30 meters high, indi­vidu­ally cho­reo­graphed to vari­ous pieces of music - clas­sic­al or pop and impress­ively illu­min­ated by col­oured spot­lights. The lake ter­race of the hotel res­taur­ant Levante offers vis­it­ors a first-class view of the spec­tacle. In com­bin­a­tion with the Arab­ic spe­ci­al­it­ies served in the res­taur­ant, the foun­tains provide a very spe­cial feel­ing.

The install­a­tion can be adap­ted to your own music or cor­por­ate col­ors for com­pany and fam­ily cel­eb­ra­tions. The 200 m² float­ing plat­form houses 116 indi­vidu­ally con­trol­lable SPECK pumps, almost half of which are oper­ated with fre­quency con­vert­ers. With a water cir­cu­la­tion of 16,000 litres per minute, they ensure impress­ive foun­tain form­a­tions. They are illu­min­ated in 16 mil­lion pos­sible col­ours by 145 LED spot­lights, which can also be con­trolled indi­vidu­ally.

BADU Alpha

New stand­ard for small pools

The smal­lest swim­ming pool pump in the premi­um range, the BADU Alpha, is the spe­cial­ist trade ver­sion of the BADU Magic II. Hydraul­ic­ally optim­ised, it has low-noise oper­a­tion and all of the premi­um advant­ages.

The BADU Alpha Eco Soft and BADU Alpha cir­cu­la­tion pumps cov­er the lower per­form­ance field in the premi­um range for smal­ler pools from 10 m³ to 60 m³. As a tech­nic­al devel­op­ment exten­sion of the BADU Magic II from the all­round range, the BADU Alpha can eas­ily replace this mod­el thanks to identic­al con­nec­tion dimen­sions and a com­pact size - upgrad­ing exist­ing equip­ment to spe­cial­ist retail level.

The main focus of the new hydraul­ic design was the energy optim­isa­tion of the pump. Thanks to a newly developed impeller and an eccent­ric design, the BADU Alpha achieves the per­form­ance range of the BADU Magic II with lower power con­sump­tion. Meas­ured at the optim­um oper­at­ing point, the effi­ciency could be improved by almost 20 %. At the same time, a con­tinu­ous optim­isa­tion of the sound val­ues was achieved. Four rub­ber feet uncouple the pump and addi­tion­ally reduce the trans­mis­sion of sound and vibra­tions.

In order to con­serve our resources, the use of raw mater­i­als has also been reduced. As a res­ult, the BADU Alpha is light­er and more com­pact than the BADU Magic II. When the hous­ing was redesigned, the strain­er tank volume was doubled for bet­ter flow rates with high­er dirt absorp­tion. The threaded ring on the strain­er tank‘s trans­par­ent lid can be loosened eas­ily with the uni­ver­sal open­ing aid.

The BADU Alpha is also a genu­ine premi­um pump in terms of mater­i­al selec­tion and work­man­ship. Fibre­glass-rein­forced plastic ensures high­er over­all strength for the hous­ing cov­er and optim­um dimen­sion­al accur­acy and con­cent­ri­city for the impeller. The BADU Alpha achieves the best cor­ro­sion res­ist­ance inside and out­side through com­pletely painted motor hous­ings and wel­ded impellers.

Just like the BADU Magic II, the BADU Alpha is also avail­able in four proven sizes from 180 to 450 watts with stand­ard asyn­chron­ous motors. In addi­tion, the BADU GREEN ver­sion, BADU Alpha Eco Soft, is avail­able with a power out­put of 500 watts. It‘s per­man­ent mag­net motor is par­tic­u­larly energy effi­cient thanks to con­stant power con­trol and vari­able power levels!

The BADU Alpha Eco Soft is cur­rently the most power­ful pump of its size on the swim­ming pool mar­ket and the first in the lower per­form­ance field that can be con­veni­ently con­trolled extern­ally - real premi­um qual­ity from BADU.

In the BADU premi­um range you will find products that rep­res­ent the highest qual­ity, reli­ab­il­ity and longev­ity for spe­cial chal­lenges and high demands around the pool; for swim­ming pool own­ers who know what they want; and for pro­fes­sion­al installers, who know how to do it. BADU premi­um products are inten­ded for spe­cial­ist retail­ers and can­not be dir­ectly com­pared via oth­er sales chan­nels.
