In plant rooms, pump shafts and collection tanks, any water that accumulates must be drained off in a controlled manner. Suitable pumping technology is also required for cleaning work, maintenance or unplanned water ingress. The decisive factors here are the volume of water, the required delivery head and the type of contaminants present.
SPECK offers submersible and sewage pumps for a range of drainage tasks in public swimming pools. From slightly contaminated water to more demanding fluids, various designs and impeller concepts are available. Models fitted with float switches enable automatic operation depending on the water level. Carefully selected materials and seals take account of the specific water conditions. In this way, our pumps support both continuous drainage and scheduled draining operations, as well as short-term applications.

Technical Specifications
The flow rate, impeller passage and materials are selected to suit the volume of water, contaminants and installation conditions.
Submersible pumps for shafts and collection points
The TOP 71 and TOP 72–80 series are fully submersible stainless steel pumps designed for use with clean, turbid or slightly contaminated water containing no long-fibre particles.
| Technical specifications | TOP 71 | TOP 72–80, depending on the model |
|---|---|---|
| Maximum flow rate | 10 m³/h | up to 21.5 m³/h |
| Maximum head | 9 m | up to 19 m |
| Fluid temperature | up to 50 °C | up to 50 °C |
| Impeller passage | 10 mm | 10 mm |
| Protection class | IP68 | IP68 |
The selection is based on the required operating point. The maximum flow rate and maximum head cannot be achieved simultaneously.
A flat suction device is available for the TOP 71 to drain residual water down to 3 mm. This residual water level must be distinguished from the switching points of an automatic float-controlled system.
Level control and electrical fittings
Various motor types and control options are available for TOP 71 to TOP 74:
- W: Alternating current, 1~ 230 V, without float-toggle switch.
- WS: Alternating current, 1-phase 230 V, with float-toggle switch for automatic operation.
- D: Three-phase current, 3~ 400 V, without float-toggle switch.
The TOP 80 is available as a three-phase version. AC variants feature built-in thermal overload protection. The pumps are supplied with a 10 m connection cable; AC versions with a Schuko plug, three-phase versions with a bare cable end.
Sewage pumps and specialised pumping applications
For applications with different requirements regarding the fluid being pumped and the installation, other pump designs are available:
- SAW-S: Wastewater pumps with an open channel impeller and a fibre-cutting device for use in public swimming pools. The specific model is selected to suit the pumping application.
- BADU 21-80/33 G-AK OL: Monobloc pump with an open impeller and a closed bellows mechanical seal. An intermediate lantern and labyrinth disc separate the seal chamber from the motor and protect the motor and bearings from leaking fluid as well as crystallising salts and minerals. The motor variant with a PTC sensor is suitable for operation with a compatible frequency converter.
Materials and water quality
The choice of materials takes into account not only contamination but also temperature, salinity and other constituents of the water.
- TOP 71 and TOP 72–80: Pump casing, impeller and suction strainer made of 1.4301 stainless steel; O-rings made of NBR.
- SAW-S 80-200: Grey cast iron casing, impeller made of the copper-tin alloy G-CuSn10 and stainless steel shaft.
- BADU 21-80/33 G-AK OL: Pump casing made of glass-fibre-reinforced PPE, impeller made of glass-fibre-reinforced PP and mechanical seal made of SiC/FKM.
For media containing chlorides, salts or minerals, the resistance of all components in contact with the medium and the suitability of the seal are assessed on the basis of the specific water composition.
