The non-self-priming horizontal multistage pump provides high hydraulic performances. Its compact and robust design is made of cataphoretic-coated cast iron. Stage chambers, impellers and diffusors are made of stainless steel. The usability in ambient temperatures up to 50°C offers a big field of application for pump integration into larger systems.

The pump is suitable for water supply and pressure boosting, industrial circulation systems, process water and cooling water circulation systems. It can also be used in washing systems as well as for irrigation.

Special features/Product advantages

Compact design to support integration
Reliable operation is supported by a cast-iron pump housing with KTL coating
Impellers and stage housing made of stainless steel
