PVM, PVMI, PVMX

Summary

Product Identification

The PVM, PVMI, and PVMX series are non-self-priming vertical multi-stage centrifugal pumps. They feature Victaulic or flanged fittings with inlets and outlets of the same size. The stages are constructed with impellers, chambers, and outlets in stainless steel. The pump cardan shaft and motor shaft are directly coupled according to IEC standard. All pumps are equipped with high-efficiency IE3 motors and a cartridge-type mechanical seal for easy maintenance.

These pumps are available in various sizes and number of stages to meet specific flow and pressure requirements.

Applications:

• Water supply
