Multistage, non-self-priming, vertical high-pressure centrifugal pump in in-line design.
The pump has a compact design with a continuous motor pump shaft and a bidirectional mechanical seal. Stage chambers, impellers, guide vanes and pump housing are made of stainless steel. Pump baseplate is made of cataphoretic-coated cast iron with oval flange connections.
The pump is suitable for water supply and pressure boosting, industrial recirculation systems, process water and closed cooling circuits. It can also be used in fire-extinguishing systems, washing systems, irrigation as well as for rainwater utilisation.
Special features/product advantages
– Suitable for drinking water and for special applications due to stainless steel structure
– Space-saving, compact and robust pump design
– Suitable for use in ambient temperatures of up to 50 °C and expanded field of application especially for system integration
