Grundfos TP and TPE vertical in-line pumps are used in a variety of applications. The pumps are all single-stage, in-line centrifugal pumps with standard motors and mechanical shaft seals. The pumps are of the close-coupled type, i.e. pump and motor are separate units. Consequently, the pumps are less sensitive to impurities in the pumped liquid than similar pumps of the canned rotor type.

Two different models of vertical in-line pumps are available. Please note that there are a number of specific product variants available for each model. Detailed information on these variants can be found in Grundfos WebCAPS.

TP pump

This pump model is notable for its high levels of reliability and efficiency.  Quiet, highly-efficient motors are standard components. All TP pumps are electro-coated to ensure high corrosion resistance.

TPE pump

The main difference between TP and TPE pumps is the motor. TPE motors have a built-in frequency converter, allowing different control methods to be employed. TPE pumps offer benefits with respect to energy savings and increased comfort.
