PRODUCT DESCRIPTION

Electric motor driven single stage end suction centrifugal pump.

APPLICATION

The range of centrifugal pumps is designed to pump clean fresh water. Other clean, non
aggressive, non explosive liquids with similar characteristics to water may be pumped.
Consult Stuart Turner for advice on such applications.
The pumps can be used for pressure boosting, fluid transfer and distribution. They are
suitable for flooded suction applications. Alternatively a maximum suction lift of

4.6 metres is permitted when using a Stuart footvalve/strainer.

Inlet pressures to the pump and ambient temperatures must not exceed the values
given in the technical specifications.

 This pump set must not be used for any other application without the

written consent of Stuart Turner Limited.

 This pump must not be connected directly to the mains water supply.
 This product should not be used for the supply of water to more than

one dwelling (house, apartment, flat).

Please read installation details carefully as they are intended to ensure this product
provides long, trouble free service. Failure to install the unit in accordance with the
installation instructions will lead to invalidation of the warranty.

STORAGE

If this product is not to be installed immediately on receipt, ensure that it is stored in a dry,
frost and vibration free location in its original packaging.

2.13 Fuses: The power cord must be sourced and supplied by the installer. Cable
selection and fuse size should be based on the motor full load current and the
surrounding conditions (supplied with 250 mm flying
lead for local requirements).

2.14 Cable Gland Fitting Instructions:
To enable correct assembly of the cable gland the
‘O’-ring (Fig. 3 item 1) must be placed over the cable
before the clamping insert (Fig. 3 item 2) can be
tightened.
Note: Cable diameter range:- 6.5 mm to 9.5 mm.

1 INSTALLATION

1.11 Secure pipework: Ensure pipework to and from pump is independently
supported & clipped to prevent forces being transferred to inlet and outlet
branches of pump.

1.12 DO NOT install a non-return valve, or devices which contain non-
return valves, in the suction (inlet) pipework to the pump. The pump
must be free to vent to the supply tank at all times.

1.13 DO NOT run against a closed valve for periods longer than 5 minutes.

1.14 DO NOT allow the supply cord to contact hot surfaces, including the
motor shell, pump body or pipework. The cod should be safely routed
and secured by cable clips.

1.15 Protection: The pump must be located in a dry position, frost free and protected
from freezing, particularly when installed in a loft (not recommended).

3 COMMISSIONING

3.11 Peripheral pumps should never be allowed to run dry. Before operating the
system, both pump and pipework should be primed. Further checks should
be made for leaks and when all is satisfactory the electrical supply to the pump
may be switched on. A vent/priming plug is fitted. To prime, release the vent plug
(see Fig. 1) until liquid emerges from the threads then re-tighten.

3.12 Safety: The motor casing can become very hot under normal operating
conditions, care should be taken to ensure it cannot be touched during operation.

3.13 Priming:

Never operate pump with inlet and/or outlet isolating valves in the
closed position. Damage will occur!

The pump must be primed (filled with water) before starting.
Turn on the service valves and vent/prime pump head.
(a) Loosen priming plug and allow an even flow of water this may take a
few seconds.
(b) Re-seal draining plug, nipping tight. The pump is now ready to start.

4 MAINTENANCE

4.11 No routine maintenance is required, but provision should be made for easy
access to the pump to allow for repairs due to normal wear and tear. Isolate the
pump from the electricity supply, turn off liquid supplies to the pump and release
pressure by opening liquid outlets before attempting repair.

4.12 Cleaners, Disinfectants and Descalents:

Acid based descalents and aggressive cleaning agents must not
come into contact with the pump. The pump must be removed from
the system prior to the use of these products. The system should be
flushed to remove all chemicals before the pump is re-connected.
If in any doubt as to the suitability of the chemical solutions, please
contact our Pump Assist helpline on 0844 98 000 97.

5 TECHNICAL SPECIFICATION

Stuart Turner reserve the right to amend the specification in line with its policy of
continuous development of its products.

*Note: Max working pressure is the maximum pressure that can be applied to
the pump internal casing under any installation conditions.
**Note: In normal circumstances the temperature of stored water should never
exceed 65 °C. A stored water temperature of 60°C is considered
sufficient to meet all normal requirements and will minimise deposition of
scale in hard water areas.

5.11 Noise: The equivalent continuous A-weighted sound pressure level at a distance
of 1 metre from the pump does not exceed 70 dB(A).
