General

Locate the pump in a frost free horizontal position where it cannot be sprayed with

water and as close to the water source as possible.

The pump is suitable for use as a portable unit and is provided with a carrying handle

for this purpose.

If the pump is to be installed in a permanent installation, it should be located in a

purpose built housing that must be capable of providing protection against rain, frost and
flooding. The enclosure must be ventilated and there should be a minimum clearance of
80 mm between pump and housing on all sides.

Care must be taken when mounting the pump that any noise is not amplified through

loose panels, pipework or other mounting medium. Noise transmission in pipework can
be reduced by fitting flexible hoses to pump inlet and outlet ports and by placing the pump
on anti-vibration mounting pads. Resilient mounting pads and flexible hoses are available
separately as optional extras, contact Stuart Turner for further details.

To prevent loss of pressure through pipework, use pipe size to match pump (25 mm

diameter) whenever possible, minimising 90° bends.

When making pipework connections to the Jet 90, use plastic fittings for direct

connection to pump.

The pipework feeds to the storage tank should be of adequate size to ensure

replenishment rate of tanks is sufficient to meet the needs of the pump.

Isolating valves should be fitted in suction and delivery pipework to enable easy

isolation and access to the pump. When pump is to be installed in areas where there is
risk of debris or scale build up within the system, it is recommended that the inlet
pipework is fitted with an inline strainer.

Pump Mounted Below Water Source (Flooded Suction Installation)

Before deciding where to locate the pump check to ensure the static inlet head (Fig. 5)

meets the minimum requirement of 1 metre and does not exceed the maximum
requirement of 5 metres.
