Grundfos vertical in-line volute pumps are used in commercial buildings for air conditioning and heating applications. The pumps are all single-stage, in-Line centrifugal pumps with standard motor and mechanical shaft seals.
The pumps are of the close-coupled type, i.e. pumps 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 WebCAPS.
This pump model is characterised by high reliability and efficiency. Quiet, highly efficient EFF1 motors are standard components. All TP pumps are electro-coated to ensure a high corrosion resistance.
The motor composes the main difference between TP and TPE. TPE motors have a built-in frequency converter, allowing different control methods to be employed. TPE pumps offer benefits within energy savings and increased comfort.
