SETTING
THE
PUMP
PRESSURE
Normally, it will not be necessary to alter the pump pressure once they have been set, although
occasionally adjustment may be necessary.
Never exceed 100 psi (6 bar) operating pressure as excessive pressure can cause the rotor to
expand and distort and consequently will become inoperative.
The pressure is adjusted by firstly loosening the lock nut on the relief valve with a ¾” AF ring
-
spanner. While holding the nut, screw in
or out the adjusting screw with an Allen
key until the desired pressure has been
reached.
The rear return pump pressure should
not need adjustment as the return is
normally open ended, requiring minimal
pressure settings; however adjustment is
the same as that for the supply pump.
Care should be exercised so as not to
pressurise the equipment.
