PNEUMATIC CONTROL GREASE PUMP HARACTERISTICSl SINGLE ACTING PNEUMATIC PUMP PUMP FLOW RATE: 0.5 a 2 cm3 PER STROKE COMPRESSION RATIO: 50:1; 3 TYPES OF RESERVOIRS STANDARD MINIMUM LEVEL CONTACT; GREASE PUMP Pneumat ic control grease pumps Simple operation control pump Robust, highly reliable pumps, comprising a steel pump body, tempered and lapped piston and a pneumatic control cylinder in which a piston slides with an anti-polish rubber gasket. The control requires a 3-way valve (available on request), with code 0045273 (110V 50Hz), code 0045274 (220V 50Hz), code 0045275 (24V 50Hz) and code 0045297 (24V DC). Depending on the reservoir, the pumps are available in three models: A. Reservoir with pressure disk (with or without spring) fixed to the level indicator rod (variable height). B. Reservoir with level indicator rod and sliding pressure disk along the rod (fixed height). C. Pressurised reservoir for very hard grease pumping.
