INTRODUCTION
The CU150 Pump consists of a petrol (gasoline) engine and water pump
which is fixed to the frame via a shock absorbing mounting.
The self-priming pump consists of a pump body, cover, impeller and
mechanical seal assembly. The inlet of the pump is higher than the inlet of the
impeller so that it can start operating when only the body of the pump is filled
with water. The inlet of the pump is fitted with a one-way valve to prevent
water syphoning back out of the pump and ensure the pump is always
primed for the next start-up.
The engine used is an air-cooled, 4-stroke OHV unit which is lightweight and
compact. It is designed to run on unleaded petrol, with a manual pull-cord
starter and simple carburettor.
The CU150 is designed only for pumping water, or water containing small
solids in suspension. It is fitted with an open impeller, therefore the suction
strainer supplied, must always be fitted to the suction hose to ensure that
debris cannot be drawn up, causing damage to the pump.
Upon receipt, unpack and lay out the components, checking against the
following list. Any damage or deficiency should be reported to your CLARKE
