Centro-Matic 82885G Fluid Lubricant Ram Pump G Series

The Centro-Matic 82885G (G Series) is an air-operated, single-stroke oil pump engineered for Centro-Matic automated lubrication systems, delivering a precise 20:1 lubricant-to-air ratio with a maximum output of 7.4 cc per forward stroke. A 600 cc translucent reservoir is refilled through a filler cap with a built-in strainer, and the unit includes a spring-loaded follower to maintain consistent loading between cycles; the pump discharges lubricant on the forward stroke and vents on the return stroke via an integrated check/vent valve. Its lubricant outlet and air inlet both use 1/4 in NPTF (female) fittings, a 3-way air valve is required, and the unit operates within a 750 psig to 1,000 psig pressure range; dimensions are approximately 6 in long, 5 1/4 in wide, and 10 3/8 in tall, with a weight around 10 lb. Designed for use within Centro-Matic automated lubrication networks, the 82885G provides controlled oil delivery for industrial equipment requiring reliable lubrication intervals.
