1. INTRODUCTION
Please read the entire manual careful before selecting, installing, commissioning and
servicing the pump.
1.1 INTENDED USE
The WITT hermetic refrigerant pump type is designed to deliver exclusively refrigerant liquid
at its boiling point.
The pump is labelled with model and design limitation for pressure and temperature.
The HRP refrigerant pump is designed with safety features, which ensures security from the
escape of ammonia; in the event the stator can leaking the pump body and the complete motor
housing is designed to 25 bar pressure to contain high pressure refrigerant will not escape
from the pump or through the electric cable connections.
Performance data of the pump are to be found in chapter 4 Technical data.
1.2 SAFETY REQUIREMENTS
All of the following specified work must be carried out by knowledgeable personnel
experienced in installation and service of refrigeration systems. All personnel must
be familiar with the national legal requirements and safety regulations. All safety
regulations and codes of practice concerning the use of refrigerants must be adhered
to, with special attention paid to protection clothing and wearing of safety glasses.
Service and maintenance should only be carried out when the pump is stopped and
the power supply disconnected.
Under no circumstances are the indicated temperature- and pressure limitations to
be exceeded.
Important! The content of this manual must be adhered to. Deviation from the
specified conditions will make any claim for liability or warrenty void.
1.3 SAFETY ADVICE
The pump is designed for use in industrial refrigeration systems of primary refrigerant.
Refrigerant is used to cool motor and bearings. Any gas that forms in the pump is discharged
to the pressure side. The electrical power consumption of the pump is low in relation to the
refrigeration capacity, due to the effect of the latent heat of the liquid being utilised.
It is very important that everybody responsible for the safe operation and
maintenance of the plant reads this manual.
I you have any problems please do not hesitate to call our service department, our staff will be
glad to assist you.

2
Avoid any tripping obstacle at ground levels, e.g. cable. If you cannot avoid such obstacles
they should be marked with two-coloured warning tape (warning sign).
Retighten all screw connections after maintenance and repair work!
If you have to disassemble any safety devices for maintenance and repair make sure that upon
completion of said work the re-assembly and proper functioning is checked!
When operating at low temperatures (< 0°C) freeze bites can occur when the surface is
touched. Therefore always wear appropriate protection clothing.
1.4 DISCLAIMER
Even when using the pump for the intended purpose it cannot be entirely excluded that a dan-
ger remains for the life of the user. Translations are carried out to the best of our knowledge.
We are unable to accept any liability for translation errors.
We reserve the right to change descriptions, graphs or other statements.

All data and information on the operation and maintenance of the refrigerant pump is provided
based on our extensive experience and to the best of our technical knowledge.
Our liability or warranty is excluded, if:
·information and instructions in the operating manual are ignored,
·the refrigerant pump including accessories is operated incorrectly or is installed contrary to
these installation instructions
·the refrigerant pump is used for applications other than that for which it was intended,
·safety devices are not used or disconnected
·there have been modifications made without written approval
·the safety regulations are not adhered to
·the refrigerant pump including its filters and required safety devices has not been main-
tained or repaired correctly with respect to frequency or competence this includes the use
of approved spare parts.
Opening the pump within the warranty period will void all implied or explicit
guarantees!
Always return the pump to the supplier for repair or order an exchange pump.
When exchanging any parts respective spare parts only genuine spare parts are to be used.
Statements in this manual shall also apply to any service fluids.

4.7 DESCRIPTION OF OPERATION
From the surge drum refrigerant liquid flows into the suction chamber of the pump. In the suction
connection a conical screen is placed. A special design of the suction chamber reduces the inlet
friction. The pressure is increased in two stages through impellers and intermediate pieces. A
built in ejector is designed to provide adequate cooling of bearings and motor.
By the differential pressure in the pump some of the liquid refrigerant is bled to the back bearings
through the hollow shaft. On top of each intermediate piece there is a small bypass hole connect-
ing the suction and discharge side. When gas has collected in the discharge chamber it can vent
through these holes to the suction chamber and from there returning to the surge drum. It is
important that the downleg must be designed in such a way that the pump venting can take place
(see chapter 6).
For the HRP 3232 the design of a vertical motor shaft allows the free flow of any gas bubbles that
may form.
Pumps with horizontal motor shaft (HRP 5040, HRP 5050, HRP 8050 and HRP 10080) are
equipped with a sensor behind the bearing filter to detect wear of the bearings. While the pump
is at stand still at connection (position 77) on the out-side of the pump you can measure the
electrical resistance through the shaft. If there is a short circuit, i.e. down to earth, the bearings
are worn and the pump should be sent in for repair.
Transformer oil is used in the stator housing between the motor can and the outside casing. This
oil is useful to prevent moisture entering the stator, conducts the motor heat away to the outside
casing.
A thermistor is integrated in the stator windings to sense any abnormal rise in temperature and
interrupt the motor supply.

In CO2-systems with minimum flow line the given volume flow is not fully available for the system.
A part of the pump volume flow will be by-passed via minimum flow line back into the vessel.

5. APPLICATIONS
5.1 GENERAL
In industrial refrigeration systems pumps are used to deliver refrigerant to the evaporators.
WITT hermetic refrigerant pumps are designed especially for this purpose. The principle of a
pump re-circulation system is shown in fig. 4.
Fig. 4 principle of pump re-circulation system
WITT HRP refrigerant pumps differ from conventional centrifugal pump designs due to the fact
that large volumes of entrained vapour (gas bubbles) do not completely stop delivery of the
refrigerant liquid.
Large volumes of gas occur in the pump suction when the evaporation temperature of the plant
varies during the production cycle, particularly when starting the compressor (pull-down) and
during the rapid loading or unloading of compressor steps of capacity.
Large amounts of gas bubbles in the pump suction line will cause the mass flow of liquid re-
frigerant to be reduced.
Special attention has to be taken to ensure that the pump suction lines are generously sized.
It is important hermetic pumps are supplied with liquid refrigerant at all times. Long
periods of cavita
-
tion must be avoided, as this will cause premature failure of the
pump. It is important the installation instructions in chapter. 6 are correctly
understood and followed.
When a minimum flow into the system can be guaranteed at all times, no by-pass lines are
required (see chapter 6)
OPERATIONAL LIMITATIONS
All HRP pumps are suitable for use at 50/60 Hz and all common refrigerants, e.g. NH3, CO2,
R134a, R404a, R410, R507, etc.

32
HRP8050 requires, when operated with synthetic refrigerants (HFC, HFO), e.g.
R134a, R404A, R410, R507, a larger motor. Therefore these re
-
frigerants must be
specified w
hen ordering!
A horizontal separator is recommended: this gives greater surface area for the settlement of
any oil and stable
suction head conditions.
5.2 DETERMINATION OF THE DELIVERY HEAD
The required delivery head is the resistance the pump needs to overcome to supply the evap-
orator with the high-est pressure loss with sufficient liquid refrigerant (in most cases this will
be the furthest distant evaporator).
The delivery head is depending from:
·Height difference between pumps and evaporators
·Resistance of pipe work and evaporators
·Pressure losses of valves and fittings in the delivery line
·Density of the refrigerant
The max. allowable delivery head should never be exceeded, because otherwise the pump is
operated outside the permitted range and will see internal damages (see chap. 6.5)
5.3 DETERMINATION OF THE REQUIRED FLOW
The evaporators have to be supplied with sufficient liquid refrigerant, so that
·The surface of the evaporators is fully used
·Supply to several evaporators with ifferent duties is as even as possible.
The re-circulation rate is calculated as follows:
Re − circulation rate = mass flow pump
evaporated refrigerant = !pump
!Q0
A re-circulation factor of 4 means that 3 parts refrigerant are returned as liquid and 1 part is
evaporated.
The re-circulation rate depends on the type of evaporator equipment and operation conditions.
The larger the duty, loading rate, the greater the recommended re-circulation factor.

5.4 ADAPTATION TO PLANT REQUIREMENTS
Fig. 5 shows different plant operating conditions. The delivery head H is shown in relation to
the required plant capacity Q.
Performance curve characteristics of the refrigerant pump are shown in fig 5A. The different
points W mark the varying plant conditions that may occur during operation.
If the required liquid flow does not correspond with the available pump capacity then the liquid
flow to the sys-tem can be adjusted as follows:
pump capacity too large:
·
switch off a pump
·
open a liquid bypass valve, fig. 5B
·speed control of the pump, fig 5C
pump capacity too small:
·
switch on an extra pump, fig 5D
·
install a larger pump

5.5 USE OF FREQUENCY CONVERTERS
When using frequency converters the frequency should never be less than 40 Hz to ensure
the minimum required refrigerant flow is maintained.
The start/stop ramp should be set steep enough, so the check valve on the discharge valve
can open fast enough. (From experience the ramp should be set at 1 s).
Since a differential set overflow valve cannot be used for the varying pressure differences over
the pump, it must be ensured in a different way that there is always sufficient flow through the
pump.
If operating against closed evaporators is possible, a permanent open bypass line is required.
Further information regarding recommended control systems can be found in the annex at the
end.

6. INSTALLATION INSTRUCTIONS
To ensure trouble free operation some basic rules need to be applied to the installation
of the HRP pumps.
6.1 PUMP ARRANGEMENT
The installation must be designed as compact as possible below the separator or
low-pressure receiver. Allow sufficient access space around the pumps for removing
or replacing the pump, servicing valves, setting pressure difference control,
inspection and cleaning the conical strainer. Also allow space for normal frost/ice
accumulation around the pump.
Vertical distance between bottom of the separator to the pump centre shall be at
least 1 m. Greater distance will make the pump less sensitive to system pressure
fluctuations.
Particularly with CO2 applications of temperatures warmer than –10°C a
minimum suction head of 1,5 m is required!
The downleg should be positioned in such a way that gas entrainment from the return line is
minimised (e.g. installation of the return line with an elbow in a safe distance).
The suspended mounting of the pumps with threaded bars of at least 180 mm length
is recommended. HRP 5040, HRP5050, HRP8050 and HRP10080 should be
aligned horizontally, wheres the HRP 3232.
Please consider that
·A condensate trip tray can easily be placed and cleaned.
·The conical suction line filter can be cleaned easily.
·Stress in the piping system is avoided.
6.2 PUMP CONNECTION
The top connection of the suction line to the separator can be made with a down pipe with
vortex breaker.
The vortext breaker shall consist of crossed plates with a baffle plate on top to avoid any vor-
texing. Vortex breakers are available from TH. WITT.
Above the baffle plate of the vortex breaker there should be at least 15mm refrigerant level (in
CO2systems a minimum coverage of 50mm is required).
When using non-soluble oils in ammonia systems special attention must be
taken
that any oil, which may settle, does not drain into the duty or stand
-by
pump.
Therefore it is recommended that the suction down leg protrudes into the surge drum by 30 -
40 mm, depending on the vessel diameter (see fig. 6a).
