The non-self-priming horizontal multistage pump provides high hydraulic performances. Its compact and robust design with corrosion-resistant components and 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

Commissioning and maintenance are facilitated by large openings for filling and emptying the pump
Reliable operation and low noise levels are supported by the neck ring design and the corrosion-resistant lantern with cataphoretic coating
Compact design to support integration
All hydraulic parts which come into contact with the fluid, such as stage chambers, impellers and diffusors and the pump housing are made of stainless steel
Drinking water approval for all components that come in contact with the fluid (EPDM version)
