Pumps supplied with flexible inlet and outlet hoses

Flexible pipes are supplied with this pump variant. The pump inlet and outlet ports are

threaded G ¾ male. These ports are provided with a flat sealing face suitable for use with

an appropriately sized flat faced fitting and fibre or rubber washer. Ensure a water tight

seal is achieved when the pump is both stationary and running.

1) Hoses incorporating integral isolating valves

should be applied to the inlet side of pump to

satisfy servicing requirements.

2) Standard hoses with no integral isolating valve

should be applied to the outlet side of pump.

3) Use correct tool for opening and closing

integrated isolating valve to prevent damage.

Please note these valves are of quarter turn

design, rotate clockwise to close and anti-

clockwise to open. Failure to comply to these instructions could lead to valve damage.

4) WARNING - pump must not run with valve closed.

Hose to pump

The pump inlet and outlet ports have fittings which are specifically designed for

connection to the G ¾ female running nuts on the flexible hoses. The hose end running

nut is fitted with a rubber sealing washer which is held captive within the nut assembly.

Locate the hose into position and screw the nut fully onto the fitting by hand. Finally nip

tight with pliers (4 to 5 Nm) for a water tight seal (do not overtighten).
