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.

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).
