Design
Figure 1 shows the essential design of the
motor-driven pump unit GSJB.
The lubricant reservoir is located on the
pump housing. It is equipped with a stirrer in
order to homogenize the grease. There is a
grease nipple on the side of the pump hou-
sing in order to fill up the reservoir by means
of a transfer pump. It is very easy to visually
check the lubricant level with the transpa-
rent reservoir. It is equipped as option with
an electric minimal level switch, such as a
capacitive switch (greases NLGI grade 000,
00,0 and 1) or as a rocker switch (grease
NLGI grade 2).
An eccentric cam is inside the pump hou-
sing. It is actuating the different pumping
elements. An electric gear-motor, single or
thee-phase, drives the eccentric cam.
