Normb­lock 80/160

Product information: "Normb­lock 80/160"

The monoblock design facil­it­ates excel­lent cir­cu­la­tion per­form­ance, yet requires little space. The motor can be replaced without hav­ing to com­pletely dis­as­semble the pump or without hav­ing to dis­mantle the mech­an­ic­al seal. The main­ten­ance-free bel­low-type mech­an­ic­al seal is highly res­ist­ant to wear and tear and not reli­ant on the dir­ec­tion of rota­tion. The seal is also lub­ric­ated by the medi­um via a cir­cu­la­tion line, which makes it highly dur­able. The pump shaft of stain­less steel 1.4571 is pro­tec­ted by a shaft pro­tec­tion sleeve also made of stain­less steel 1.4571. This pre­vents wear and tear of the pump shaft.

Dir­ectly moun­ted, DIN-IEC three-phase, low-noise oper­a­tion, sur­face-cooled, remov­able motor. In com­pli­ance with energy effi­ciency class IE3, includ­ing the PTC res­ist­or sensor.

Field of application

Swimming pool water circulation and filtration as well as operation of swimming pool attractions in public swimming pools. Can also be used for irrigation, drainage, water supply, shipbuilding and industry.

Design

Non-self-priming, single-stage volute casing pumps with performance classification and main dimensions in compliance with NF E 11-112 and DIN EN 733 (replacement for DIN 24255). The pump and replaceable norm motor are flanged together to form a monoblock unit. The volute casing has replaceable corrosion-resistant wear rings. The closed impellers are individually balanced to suit the respective operating conditions. They are adjusted to meet the requirements of quality grade 6.3 in compliance with DIN ISO 1940. This ensures smooth and quiet operation and long operating life of the entire pump assembly.
