Grundfos vertical in-line pumps (TPE)

Grundfos vertical in-line volute pumps with integrated frequency converters are used in a number of applications including air conditioning and heating. The pumps are all single-stage, in-line centrifugal volute pumps with standard motors and mechanical shaft seals.

The pumps are close-coupled, meaning that the pump and motor are separate units. Consequently, the pumps are less sensitive to impurities in the pumped liquid compared to similar canned rotor pumps.

Two versions exist:
TPE Series 1000
TPE Series 2000.
The TPE Series 1000 is the basic version with frequency converters built-into the motors. TPE Series 2000 is further equipped with a factory-fitted integrated differential pressure sensor. This makes the TPE Series 2000 range a preset solution for quick and safe installation.
Max flow: 350 m3/h
Max motor size: 22 kW
