SITING OF THE PUMP/PIPEWORK

WARNINGS:

Pump Location

If possible site the pump in a location where in the unlikely event of a

liquid leak, any spillage is contained or routed to avoid electrics or

areas sensitive to liquid damage.

Care should be taken to protect the pump from frost and freezing.

Ensure pipework to and from pump is independently supported to

prevent stress on the pump inlet and outlet branches.

Do not fit a non-return valve, or devices which contain non-return

valves, in the suction (inlet) pipework to the pump. Exceptions can

be made in the case of suction lift installations when a footvalve is

required.

Always install isolating valves to both suction and delivery pipework.

When a footvalve is required on installations that incorporate

automatic pump control, it is recommended that a suitable pressure

relief valve be fitted in the discharge (outlet) pipework from the pump.

Do not run against a closed valve for periods longer than 5 minutes.

Do not allow plastic pump parts to come into contact with oil or

cellulose based paints, paint thinners or strippers, acid based

descalents or aggressive cleaning agents.

Do not introduce solder flux to pumps or pump parts manufactured

from plastic. All solder joints should be completed and flux residues

removed prior to pump connection.

The motor casing can become very hot under normal operating

conditions. Care should be taken to ensure it cannot be touched

during

operation.

Site the pump in a dry, frost-free position where it cannot be sprayed with water and as

close to the liquid source as possible.

The pump enclosure must be ventilated and there should be a minimum clearance of 80

mm between the pump and housing on all sides.

To prevent loss of pressure through pipework, use pipe size to match pump whenever

possible, minimising 90° bends.

It must be ensured that storage capacity of the liquid supply is adequate for the flow

rates required by the pump.

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

replenishment rate of tank 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 the pump is to be installed in areas where there is a 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 Above Liquid Source (Suction Lift)

The pumps can be used in a suction lift installation providing the height of lift is within the

limits specified in the limits of application section.

A footvalve and strainer must always be used and the suction pipework size must match

the pump.
