MSA-10 (Air Operated) Pump

The MSA-10 is an air-operated pump with an adjustable volume output. It is designed to be used in series progressive oil or grease lubrication systems. Lubricant can be supplied to the MSA-10 pump by either a gravity feed reservoir or a pressurized source such as a bulk header that exerts up to 500 psi at the pump inlet. This pressure handling capability is a result of the pump pistons valving action which prevents lubricant from flowing into the lube system when the piston is in the priming position. The MSA-10 is supplied as a single-acting pump. However, it can easily be field-converted to double-acting by removing the plastic vent plug from the double-acting port and installing an air line.
