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.

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.

• 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
