Reservoir
The reservoir stores the lubricant. Different reservoir
designs and reservoir sizes exist in accordance with the
pump variant.
Reservoir cover
Is used to fill the reservoir with clean and suitable
lubricant, and also to protect the lubricant from
contamination.
Reservoir ventilation
Aerates the reservoir while the pump is working and
lubricant is being fed.
Stirring paddle
The stirring paddle homogenizes and smooths the
lubricant while the pump is running. In addition, the lower
vertical part of the stirring paddle presses the lubricant in
the direction of the pump elements and improves the
suction characteristics of the pump as a result.
Pump housing
The pump housing contains the motor, the electrical
connections, the filler nipple, the pump elements, the
power supply board and (if applicable) the intermittent
low-level signal.
Pump elements
The pump can be equipped with up to 3 pump elements.
Filler nipple
Used for filling the pump from below. Once the filler
nipple is removed, corresponding accessories can be
used to connect the external grease return from the
pressure limiting valves to the pump elements through
this port.
