Mounting the pump
elements
It is possible to mount up to 6 pump ele-
ments on the GSJB unit.
There are six outlet ports radially placed
around the GSJB pump unit housing. The
pump element can be mounted in one of
these ports. It is directly connected to the ec-
centric by the groove.
• Screw off the closing plug (initial moun-
ting) or the pumping element (replacing).
• Remove bothersome lubricant between
the fixing thread and the groove.
• Pull out the piston of the new pump ele-
ment as far as possible.
• Insert the pump element with a light
upward inclination until the eccentric
(
† fig. 5
). The seal has to be between the
pump element and the pump housing.
• Set the pumping element horizontally
such as the piston heel is coming into the
eccentric groove (
† fig. 6
).
• Screw in the pump element.
!
Mount and dismount pump ele-
ments only when the unit is dis-
connected from power supply. Failure to
comply with this requirement may lead
to bodily injury or damage of the unit.
