PREPARATION FOR USE

Because of the variety of possible installations, no plumbing accessories are

supplied with your pump, however accessories designed specifically for this

range of pumps are available from your nearest CLARKE dealer. Contact your

CLARKE dealer for further information.

IMPORTANT: The pump MUST NOT be connected to the mains power supply

until all hose/pipe installation is completed.

POSITIONING THE PUMP

A typical installation of the pump is shown in Fig 1. Connect the suction and

discharge hoses to the pump housing to achieve an air-tight seal. Ensure there

is no damage to the hoses which must be well protected and supported.

The pump must always be installed

and operated in a horizontal position

i.e. with the outlet port facing

vertically upwards. The fixing holes in

the base should be used to secure

the pump firmly in its operating

position. Always ensure there is

adequate air circulation around the

motor.

Avoid situations where the pump

could become drenched with water.

Neither the motor or terminal box are designed to be waterproof.

Position the pump as near to the water source as

possible.

Ensure there is adequate drainage and there is no

risk of damage to property as a result of water

being discharged.

A foot valve/filter should be fitted to the lower end

of the suction hose, as illustrated in Fig 2, in order to

retain water in the suction system and more

importantly, to prevent the possibility of large

objects entering the pump body.

The performance of your pump will be affected by

the diameter of the inletpipe - any restriction will

greatly reduce the flow. We strongly recommend

that you use a pipe diameter as large as practical.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

A gate valve may be installed in-line on the delivery side (outlet port) of the

pump which can be adjusted as required to regulate the flow of water, and

can assist in priming the pump.

CAUTION: DO NOT PLACE ANY SUCH OBSTRUCTION ON THE SUCTION (INLET) SIDE

OF THE PUMP UNLESS IT IS AN ISOLATOR VALVE IN A GRAVITY FED SYSTEM. THESE

PUMPS SHOULD NOT BE OPERATED WITH THE DELIVERY VALVE COMPLETELY

CLOSED.

To prevent unnecessary strain or possible distortion to the pump, ensure that

adequate support is provided to the hoses and or pipes. They will be

considerably heavier when filled with water.

Should contaminants come into contact with the pump, flush through with

cold water as soon as possible to prevent damage to the pump.

Protect the pump and pipework from freezing. The formation of ice may

cause serious damage.

Where the pump is to be a permanent fixture, the connections to the pump

MUST be flexible, i.e. a short piece of hose should be inserted between the

rigid pipework and the pump.

IMPORTANT: An air leak in the suction line will inhibit priming and reduce the

capacity of the pump.

Pay particular attention to the following:

• Keep all hoses as short and straight as possible and avoid sharp

bends.

• Ensure there is adequate drainage for the discharged water.

• If a flexible hose must be laid across a roadway, protect it with

planking.

(Instantaneous shut off pressure, applied when a vehicle runs across an

unprotected hose, could cause “hydraulic shock”, which can damage the

pump and/or the hose).

CONNECTING A FOOT VALVE/FILTER

1. Attach a foot valve/filter to the end of the suction hose to prevent stones

etc, from being drawn up, which could cause damage to the pump. Keep

the strainer clean. If it is likely to clog with dirt or debris, proceed by either:

• Preparing a bed of stones on which to rest the strainer.

• Tying the strainer so that it stays clear of the bottom of the pit, pond

or excavation.

• Tie the strainer inside a basket or bucket.

PRIMING THE PUMP

Remove the filler plug on top of

the pump case and prime the

pump by filling completely with

water, leaving no air gap.

Remember the pump is self-

priming only when filled, after

which, it will re-prime itself without

refilling. Refilling is necessary only if

the pump has been drained, or if

all the water has been lost.

OPERATION

1. Open any valves in the pipeline.

2. Connect the power supply and switch the pump ON.

3. Wait for the pump to prime.

4. If the motor fails to start or the pump does not deliver water refer to

TROUBLESHOOTING.

NOTE: Filling the suction pipe with water will speed up the priming

process, and it is recommended that a non-return valve be fitted

to the end of the suction pipe.

In the event of blockages, where debris has entered the suction chamber, the

chamber can be taken off and cleaned out as described under

Maintenance.

5. Periodically, check the level of the water being removed and never allow

the pump to run dry.

6. Stop the pump by switching the pump the OFF (O) position.

ADDITIONAL CONSIDERATIONS

• Strain caused by vibration can be reduced by connecting a short

flexible hose between any rigid pipework and the pump.

• Any restriction in the pipeline will greatly reduce the flow.

• Ensure that the hoses and pipes are supported along their entire

length. They will be considerably heavier when filled with water.

• We recommend that you install isolation valves either side of the

pump in order to isolate the pump during maintenance/removal.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

• A gate valve may be installed in-line on the delivery side of the

pump which can be adjusted as required to regulate the flow of

water and can assist in priming the pump.

7. If there is a chance of freezing, protect the pump and pipework with

suitable lagging. The formation of ice may cause serious damage.

SPE PUMP PERFORMANCE

AFTER USE

After use, and if the pump will not be used over the winter period, or if there is

danger of freezing, always drain the pump body.

If the pump has been used with contaminated or salty water, it should be

thoroughly flushed with clean water following use, both inside and out. It

should then be drained and covered over, if not already sheltered from the

weather.

If the pump is seized following a period of inactivity, it may be possible to free

it off. Ensure the pump power supply is turned off before by inserting a

screwdriver into either the infeed or discharge port and dislodging a jammed

impeller. If this is not successful it may be necessary to remove the relevant

mounting bolts to separate the pump body and clean away any incrustation.

Re-prime the pump when returning to service.

In the event that overhaul of the pump or motor is necessary, contact your

Clarke service department.

MAINTENANCE

The only maintenance required is a

regular inspection to ensure that

leaves and other debris is not

blocking the passage of water

through the pump.

If you suspect the pump is blocked

by mud, silt, leaves etc, disconnect it

from the mains supply and backflush

to clear any blockage though the

drain plug.

Always keep the pump in a clean

condition, checking regularly for

loose bolts or a damaged power

cable etc.

If the pump has been used under arduous conditions leading to internal

fouling or damage, the impeller housing can be removed by undoing the four

socket-headed impeller housing bolts shown in Fig 4.

The impeller can then be inspected for damage.

• Note that the pump also includes a 13mm hexagonal connector

used to extend the bolts between pump & motor housing.

STORAGE

After use, drain the pump body whenever there is danger of freezing. If the

pump has been used with contaminated or salty water, it should be

thoroughly flushed with clean water following use, both inside and out. It

should then be drained before replacing the drain plug and storing in a clean

dry environment not exposed to the weather.

In the event that dismantling and overhaul of the pump is necessary, contact

your CLARKE International Service Department on 020-8988-7400.

ACCESSORIES

A wide range of accessories is available, including Filters, Foot Valves, Hoses,

Couplings and 90° Hose Adaptors, etc. Contact your Clarke dealer for further

information or Clarke International Sales Department on 01992 565333.

These pumps are supplied with a 1” male 90° hose adaptor.
