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.

4. Speed regulation
Affinity equations
Normally, TPE pumps are used in applications
characterized by a variable flow. Consequently, it is
not possible to select a pump that is constantly operat-
ing at optimum efficiency.
In order to achieve optimum operating economy, select
the pump on the basis of the following criteria:
• The max. required duty point should be as close as
possible to the QH curve of the pump.
• The flow rate at the duty point required should be
close to the optimum efficiency (eta) for most
operating hours.
Between the min. and max. performance curve TPE
pumps have an infinite number of performance curves
each representing a specific speed. Therefore it may
not be possible to select a duty point close to the max.
curve.
Fig. 1 Min. and max. performance curves
In situations where it is not possible to select a duty
point close to the max. curve, affinity equations can be
used. The head (H), the flow (Q) and the input power
(P) are the appropriate variables you need to be able
to calculate the motor speed (n).
Note:
The approximated formulas apply on condition that the
system characteristic remains unchanged for nnand nx
and that it is based on the formula H = k x Q2, where k
is a constant.
The power equation implies that the pump efficiency is
unchanged at the two speeds. In practice this is not
quite correct.
Finally, it is worth noting that the efficiencies of the
variable frequency drive and the motor must be taken
into account if a precise calculation of the power sav-
ing resulting from a reduction of the pump speed is
wanted.
WinCAPS and WebCAPS
WinCAPS and WebCAPS are both selection programs
offered by Grundfos.
The two programs make it possible to calculate a TPE
pump’s specific duty point and energy consumption.
By entering the dimensional data of the pump,
WinCAPS and WebCAPS can calculate the exact duty
point and energy consumption. For further information,
please contact Grundfos or see Grundfos’ homepage
www.grundfos.com.

Note:
When motors installed more than 3000 ft (914 m)
above sea level, the rated motor output will fall due to
the low
density and consequent low cooling effect of the air. In
such cases, it may be necessary to use an oversize
motor with a higher output.

6. Pumped liquids
Pumped liquids
TP, TPE pumps are suitable for pumping thin, clean,
non-aggressive and non-explosive liquids, not
containing solid particles or fibers that may
mechanically or chemically attack the pump; please
see "List of pumped liquids" below.
Examples of liquids:
• Central heating system water (we recommend that
the water meets the requirements of accepted stan-
dards on water quality in heating systems).
• cooling liquids.
• domestic hot water.
• industrial liquids.
• softened water.
If glycol or another antifreeze agent is added to the
pumped liquid, the pump must have a shaft seal of the
type RUUE.
The pumping of liquids with densities or kinematic
viscosities higher than those of water can cause
• a considerable pressure drop
• a drop in the hydraulic performance
• a rise in the power consumption.
In these situations, equip the pump with an oversize
motor. If in doubt, contact Grundfos.
If the water contains mineral oils or chemicals, or if
other liquids than water are pumped, choose the
O-rings accordingly.
Liquid temperature
Liquid temperature:
–13 °F (–25 °C) to +284 °F (+140 °C).
Please note that shaft seals operating close to their
maximum temperature will require regular
maintenance, i.e. replacement.
List of pumped liquids
Grundfos TP pumps are designed for circulation
systems with constant flow; TPE pumps are for sys-
tems with variable flow.
Thanks to their design, these pumps can be used in a
wider liquid temperature range than pumps of the
canned rotor type.
A number of typical liquids are listed page 11.
Other pump versions may be used, but we consider
the ones stated in the list to be the best choices.
The list is intended as a general guide only, and it
cannot replace actual testing of the pumped liquids
and pump materials under specific working conditions.
If in doubt, contact Grundfos.
However, use the list with some caution as these or
other factors may affect the chemical resistance of a
specific pump version:
• concentration of the pumped liquid
• liquid temperature or
• pressure.

Construction
Grundfos TP, TPE pumps are single-stage,
close-coupled pumps with in-line suction and dis-
charge ports flanges of identical diameter.
The pumps are equipped with a fan-cooled
asynchronous motor. Motor and pump shafts are
connected via a rigid two-part coupling.
The pumps are equipped with an unbalanced
mechanical shaft seal.
The pumps are of the top-pull-out design, i.e. the
power head (motor, pump head and impeller) can be
removed for maintenance or service while the pump
housing remains in the pipework.
As radial and axial forces are absorbed by the fixed
bearing in the motor drive-end, the pump requires no
bearing.
Pumps with bronze pump housing are suitable for
circulation of domestic hot water.

seal with tungsten carbide/carbon seal faces and
secondary seals of EPDM (standard seal).
•RUUE
The RUUE shaft seal is a Grundfos O-ring seal with
reduced tungsten carbide/tungsten carbide seal
faces and secondary seals of EPDM.
•AUUE
The AUUE shaft seal is a Grundfos O-ring seal with
fixed seal driver, tungsten carbide/tungsten carbide

Construction
TPE Series 2000 pumps are based on TP pumps.
The main differences between the TP and the TPE
Series 2000 pump range are the motor and the
factory-fitted integrated differential pressure sensor.
The motor of TPE Series 2000 pumps has a built-in
variable frequency drive designed to continuously
regulate the pressure based on the flow demand.
The TPE Series 2000 range is recognized as a
pre-configured solution for quick and safe installation.

for automatic adaptation of performance to current
conditions.
This ensures that the energy consumption is kept at a
minimum.
TPE Series 2000 pumps can operate in any duty point
within the range between 25 % and 100 % speed.
In the QH-chart the 100 %-curve corresponds to the
curve for a pump fitted with a standard fixed-speed
motor.
Depending on the nature of the application, TPE
Series 2000 pumps offer energy-savings, increased
comfort or improved processing.
TPE Series 2000 pumps are suitable for applications
where you want to control the pressure.

Differential proportional pressure
TPE Series 2000 pumps are factory-set to proportional
pressure. We recommend proportional pressure con-
trol in systems with relatively large pressure losses as
it is the most economical control mode.
TPE Series 2000 pumps set to proportional pressure
control continuously adjust the pump head to the
system water requirement.
The charts below show possible control modes of TPE
Series 2000 pumps in different applications.
Control options
Communication with TPE Series 2000 pumps is
possible via:
• a central building management system
• remote control (Grundfos R100) or
• a control panel.
The purpose of controlling TPE Series 2000 pumps is
to monitor and control the pressure.
For further information on control options of TPE
pumps, see page 20.
Pump selection guidelines
Differential proportional pressure control
TPE 2000 pump operating range in differential pres-
sure control mode is between 3/4th of the maximum
head (shut off) to 1/4th of the maximum head. Select
pump to operate within this range when pump is run-
ning full load speed. With differential proportional con-
trol, pump will follow a straight line between set point
and and half of the set point at closed valve as shown
below.
Constant differential pressure control
The setting range for constant pressure control is
between maximum head to 1/8th of the maximum
head.

10. Communication
Communication with TPE pumps
Communication with TPE pumps is possible via a
central building management system, remote control
(Grundfos R100) or a control panel.
Central building management system
The operator can communicate with a TPE pump even
when he is not present near the pump.
Communication can take place via a central building
management system allowing the operator to monitor
and change control modes and setpoint settings.
Fig. 7 Structure of a central building management system
Remote control
The R100 remote control produced by Grundfos is
available as an accessory.
The operator communicates with the TPE pump by
pointing the IR-signal transmitter at the control panel of
the TPE pump terminal box.
Fig. 8 R100 remote control
The operator can monitor and change control modes
and settings of the TPE pump via the R100 display.
Control panel
The operator can change the setpoint settings manu-
ally on the control panel of the TPE pump terminal box.
