Pentair PVM Vertical Multistage Centrifugal Pumps

SURFACE PUMPS - VERTICAL MULTISTAGE

Pentair PVM Vertical Multistage Centrifugal Pumps. High hydraulic efficiency, Motor designed to EN standards.

The PVM are non-self priming vertical multistage pump of in-line design, flange or with Victaulic coupling with equally sized suction and discharge ports. Stage construction with stainless steel impellers, chambers and pressure casing. Pump stub shaft and motor shaft of the IEC-standards motor are directly close coupled.

All pumps are equipped with high efficiency motors (IE3) and with a cartridge type mechanical seal for easy maintenance.
PVM pumps have different pump sizes and various numbers of stages to provide the flow and the pressure required.
