8.3.1 Functional description of the version with follow-up piston
The following listed positions can be found in fig. 21.
A DC motor optionally with 12 or 24 V DC (pos. 1) drives the eccentric shaft (pos. 3) via a worm drive (pos. 2). The ,
delivery pistons (pos. 4) of the integrated pump elements are pushed into the pump element body (pos. 5) by the rotary
movement and the eccentricity of the shaft (= delivery stroke). The delivery pistons return into their initial position by the
compression springs (pos. 6) and suck new lubricant from the reservoir (= suction stroke).
Non-return valves are integrated in the pump elements which prevent that lubricant, which has already been displaced, is
sucked back. An agitator blade (pos. 8), which is firmly connected with the eccentric shaft, is located above the centering
ring (pos. 7), which is used as grease strainer. The agitator blade pushes the lubricant towards the pump elements. There
is a follow-up piston (pos. 10) in the reservoir (pos. 9) which is pushed onto the lubricant by a conical compression spring
(pos. 11). By this, the follow-up piston pushes the lubricant evenly to the agitator blade or to the pump elements. It is
therefore not strictly necessary to assemble the device vertically.
If the reservoir is empty, the follow-up piston pushes onto a feeler (pos. 12), which sends a signal to the integrated control
unit. The integrated control unit displays the error
into the lubrication system (see chapter 13 „Troubleshooting").
The device can be filled via a cone-type zerk which is located in the pump housing. In order to avoid an overfilling of the
device, a pressure limiting valve (pos. 13) is integrated in the pump housing which is used as overfill protection.
Refer to chapter 7.2 „Filling with lubricant" for further information on filling the device.
