Introduction
TP pumps are designed for applications such as
• district heating systems
• heating systems
• air-conditioning systems
• district cooling systems
• water supply
• industrial processes
• industrial cooling.
Most of the pumps are available with either standard
motors (TP and TPD) 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.
TP pumps – uncontrolled pumps
The TP range is divided into the following four groups
based on their construction: TP Series 100, 200, 300
and 400 pumps.
TP Series 200 with flange connection
DN 32 to DN 100 and motor sizes from 0.12 to 3 kW.
For further information, see page 20.
TP Series 300 with flange connection
DN 32 to DN 200 and motor sizes from 0.55 to 55 kW.
For further information, see page 22.
TP Series 400 with flange connection
Grundfos offers two TP Series 400 versions:
• 10 bar version with DN 150 to DN 250 flange and
motor sizes from 37 to 132 kW.
• 25 bar version with DN 100 to DN 250 and motor
sizes from 7.5 to 315 kW.
For further information about TP Series 400 pumps, see
page 24.
TPE pumps – speed-controlled pumps
Based on the construction and choice of material of TP
pumps, Grundfos offers speed-controlled TPE Series
1000 pumps.
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 built-in frequency converter.
Via an external signal (from a sensor or a controller),
TPE Series 1000 pumps allow for any configuration and
control method required: Constant pressure, constant
temperature or constant flow.
Note: TPE Series 1000 pumps are delivered without a
differential-pressure sensor.
TPE Series 1000 pumps are based on TP Series 200
and 300 pumps. The pump materials are the same as
those of the TP pump range.
For further information, see page 26.
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 the pump performance
• communication with the pump.
ATEX-approved TP pumps
On request, Grundfos offers TP and TPD pumps with
ATEX-approval.
All ATEX-approved TP pumps are in accordance with
Council directive 94/9/EC (Group II, category 3).
High-efficiency motors
TP pumps are fitted with high-efficiency motors.
2- and 4-pole TP pumps with motor sizes from 1.1 to
90 kW are fitted with high-efficiency motors (EFF1).
EFF1 is the highest efficiency class defined by CEMEP.
