with compressed air systems.
The pump electric control valve will be 3 ways type (line-cylinder-drain).
Pumping lubricant
: mineral grease with no abrasive materials.
Air control pressure
: min. 3 bar (44.1 psi) – max. 6 bar (88.2 psi).
Reservoir filling
: grease gun with valve UNI 7663 – shape “A” – 1/8” NPT.
Lubricant outlet
: G 1/4” bsp.
Compressed air inlet
: G 1/8” bsp compression cone seating 6 mm. (0.2 in.) tube.
Cartridge shaped filter positioned at the grease gun inlet.
