TPE E-circulators

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.

Speed regulation

TPE E-circulators

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.

Maximum 95%.

Ambient temperature

Maximum ambient temperature +104 °F (40 °C).

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.

Pumped liquids

TPE E-circulators

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.
