Side Channel Centrifugal Pump

SRZS (Self-priming with special NPSH stage, PN40)

Pump is a combination of centrifugal pump & a side channel pump, with a special suction impeller and an axial suction branch

Extremely low NPSH value

Capable of handling aerated liquids

Self-priming

Low operating noise level

Positive suction head below 0.5 metres

Taking into account their various material designs, the SRZS range has been especially conceived for: • Difficult suction conditions • Pumping liquids approaching the boiling point • Low positive suction head • Liquid with low steam pressures.
