Grundfos TP-TPE inline circulator pumps are used in a variety of applications. The pumps are all single-stage, in-line centrifugal volute 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 volute 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 Product Center.
TP pump
This pump model is notable for its high levels of reliability and efficiency. Quiet, highly-efficient IE3 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.

Features and benefits
Optimised hydraulics for high efficiency
Reduced power consumption
High-efficiency motors
TP pumps are fitted with high-efficiency motors
High-efficiency motors provide reduced energy consumption
2-pole and 4-pole TP pumps from 0.75 kW to 375 kW have IE3 motors (By March 2012)
Top-pull-out design
Easy dismantling for service
In-line design
Unlike end-suction pumps, in-line pumps allow the use of straight pipework, which often results in reductions in installation cost and amount of space occupied
Hydraulically and mechanically balanced impeller (Series 300 and 400)
The impeller is hydraulically and mechanically balanced to increase the life of motor bearings and shaft seals
Pump housing and pump head/motor stool are electro-coated
Improved corrosion resistance
TPE, TPED – pumps with built-in frequency converter
Reduced power consumption
TPE and TPED motors are based on IE3 motors (except 18.5, 4-pole).
