Pump element (PE)
The pump element supplies the lube points with lubricant or forward the output rate to the distributor.
Functional description:
The actuation of the supply piston is enforced via the piston eccentric ring. During the suction process the supply
piston is moved into a final position. The metering chamber is filled with lubricant and another turing movement of
the eccentric ring effects that the supply piston closes the suction drilling whereby lubricant is supplied towards
the outlet via the non-return valve.
The pressure line shall only be connected if the pump element supplies air free. The non-return valve avoids that
lubricant is drawn back. Supplied lubricant always has to be clean to ensure the function of the non-return valve.
The pump elements can be ordered with or without pressure limiting valves. The installed pressure limiting valve
predects the system from overload.
