For GMG-L:
Loosen the pump element cautiously. Prior to removal, tilt the
pump body slightly such that the delivery piston‘s head is moved
out of the groove of the pressure ring.
Insert the new pump element diagonally into the location hole in
the casing with the delivery piston being pulled out up to its half
approximately. Installation and commissioning will be facilitated if
the hole that serves to accommodate the delivery piston is filled
with grease. Do not put the pump element into horizontal position
and screw it down unless the deli
very piston’s head is resting at
the pressure ring and engaging its groove.
For other repairs, turn to WOERNER, please.
