INSTALLATION
1. Remove connecting flanges (11) and remove the paper membranes
used to close off the inlet and outlet openings during transit.
2. Depending upon the intended use, it may be desirable to flush out any
residual oil from inside the pump.
3. Install the pump in a vertical position on a wall or similar
structure, with the outlet (indicated by the raised lettering
e.g. K2) facing upwards as shown (fixing bolts not supplied).
Also, always observe any arrows on the pump cover,
indicating the direction of flow.
• Vertical mounting is essential because the valves close
under gravity and if they cannot close, the pump cannot produce
suction.
4. Fit the wooden handle, by tapping gently to ensure it is a tight fit on the
handle spike. The handle can be repositioned to point in any direction
after removing the shaft end nut (9).

3
5. Connect any inlet and discharge hose connectors which are compatible
with the 1” BSP connecting flanges of the pump.
MAINTENANCE
1. Ensure that the seal compression nut (3) is sufficiently tight. If not, leakage
can take place from the pump handle shaft.
2. If using the pump for water, and there is a likelihood of freezing when not
in use, drain the pump via the access plug (15).
3. If the pump has been used for pumping any liquid likely to leave chemical
residues, it should be flushed through with clean water after use.
4. If the pump will be unused for extended periods, insert some oil through
the access plug (15) to protect the internal parts.
• Ensure the oil used does not contaminate the medium being pumped.
5. Periodically check that all nuts and bolts are tight.
A wide range of accessories are available from your nearest CLARKE dealer,
including hoses and hose adaptors and couplings.
