The PMP100 Series air operated metering pumps are unique in that each outlet/feed is an individual positive displacement pump. These pumps are ideal for dispensing precise easily adjustable volumes of a variety of fluids including: oils or grease for lubrication, inks, dyes, chemical additives and cutting fluids. The factory should be consulted before using with high water base fluids. The air operated metering pumps are: Positive displacement Self priming with up to 27 InHg (686mmHg) Will operate in any position. They are available in 1 to 15 feeds for oil or 1 to 5 feeds for grease with each feed independently and externally adjustable from 0 to .01 cu. in. (0 to .20 cu. cm.) by a micrometer thread .02 (.57mm) pitch. A patented feature allows additional pumps (AMP100) to be easily added to a PMP100-02 or more pump banks. The air operated metering pumps are intended for "on command", higher output pressure applications where a compressed air supply of 25 to 125 PSIG (172.50 to 862.50 kPa) is available. All feeds will actuate at the same time "on command" by using compressed air through a 3-way Solenoid Valve actuated by a Repeat Cycle Timer . The R100 Series filtered reservoirs are ideal for oil applications. Grease applications should use the Grease Cartridge Adapters or Grease Reservoirs.
