Pneumatic grease pump Delimon Lubrication

APPLICATION:
For lubrication at friction points on presses, stamping presses, machine tools, conveyors, etc.

FUNCTION:
By pressurizing the pneumatic cylinder the piston is lifted thus closing first the suction port. Then the lubricant inside the cap is being displaced via valve seat and ball into the piston chamber. When the piston is moving upwards, the cross bore provided, having an annular grovve, reaches the outlet ports.
These ports are not on the same level so that the lubricant is discharged alternatvely, in a premetered quantity. Relieving the pneumatic cylinders returns the piston into is initial position thus recharging the chamber between piston and cap with lubricant.
With single-line and progressive systems the total feed volume of the pump is taken from outlet "X"; through the "Y" port, in single-line systems on the other hand, the lubricant, when depressurized, is returning into the reservoir. The parameter determining the minimum pulse frequences is an empirical value dependent upon lubricant, air pressure, number of outlets, and, last but not least, piping cross- sections and length of main feed line.
