Functional description
8.1 General
The device is designed to deliver multi-purpose grease NLGI grade 2. Thanks to the use of grease cartridges of type S, the lubricant
supply can be replenished quickly and tidily.
The device is equipped with a lubricant out.et to which e. g. a progressive distributor can be connected. The lubricant quantity can be
set progressively, so that the device can be used for all lubricant circuits.
A return line can be connected to the return connection M10x1 on the device front side. The device is delivered with closed return
connection by default.
8.2 Function
All stated positions to Fig.2 (page 7)
At each pressurization with hydraulic oil (X) the supply piston (2) is moved to the left thus pressing together the pressure spring (11)
and the suction drilling (U) is closed. The Lubricant (Z) of the suction chamber (T) flows through the non-return valve (V) that avoids
a back flow, towards the pressure connection (W). After the pressure stroke the spring (11) presses back the piston (2) into its initial
position. The thereby developed vacuum sucks lubricant (Z) into the suction chamber (T) for the next stroke.
