Introduction
TP, TPE pumps are designed for applications such as
• district heating systems
• heating systems
• air-conditioning systems
• district cooling systems
• water supply
• industrial processes
• industrial cooling.
The pumps are available with either standard motors
(TP) or electronically speed-controlled motors (TPE).
The pumps are all single-stage, in-line centrifugal
pumps with standard motor and mechanical shaft seal.
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.
The TP, TPE range is divided into the following three
groups:
• TP pumps (uncontrolled standard pumps).
• TPE Series 2000 pumps (speed controlled pumps
with factory-fitted pressure sensor).
• TPE Series 1000 pumps (speed controlled pumps).
This product guide covers Series 2000 and 1000
speed controlled pumps.
Please see Grundfos publication L-TP-PG-001 for
TP (uncontrolled standard pump) product range
and details.
TPE Series 2000 pumps
The main differences between the TP and the TPE
Series 2000 pump range are the motor and the fac-
tory-fitted integrated differential-pressure sensor.
The motors of TPE Series 2000 pumps have a
built-in variable frequency drive (VFD) designed to
continuously regulate the pressure to the flow.
The TPE Series 2000 range is recognized as a
pre-configured solution for quick and safe installation.
TPE Series 2000 pumps are based on TP pumps. The
pump materials are the same as those of the TP pump
range.
For further information about TPE Series 2000 pumps,
see page 14.
TPE Series 1000 pumps
The difference between the TP and the TPE Series
1000 pump range is the motor. The motors of TPE
Series 1000 pumps have a built-in VFD.
Via an external signal (from a sensor or a controller),
TPE Series 1000 pumps allow for any configuration
and control method required: constant pressure, con-
stant temperature or constant flow.
TPE Series 1000 pumps are based on TP pumps. The
pump materials are the same as those of the TP pump
range.
For further information about TPE Series 1000 pumps,
see page 17.
Why select a TPE pump?
A TPE pump with electronic, speed-controlled
adaptation of performance offers these obvious
benefits:
• energy savings
• increased comfort
• control and monitoring of pump performance.
• communication with the pump.
