The non-self-priming horizontal multistage pump reaches 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
– Easy and fast commissioning/maintenance thanks to big holes for pump-filling and emptying
– High reliability in terms of robustness and noise thanks to the neck ring design and corrosion-resistant lantern with cataphoretic coating
– Compact design for an easy 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)
