LUBRICATION SYSTEMS

The Model 7500 pump is a heavy-duty precision metering pump capable of accurately pumping small flows of either mineral or synthetic oil to machinery injection points. The single-piston pump is mechanically driven from a camshaft in the reservoir and is adjustable from 1 to 27 drops per stroke, depending on the piston size. Pressures. The pump can develop pressures up to 7,500 psi, depending on the piston size (3/16, 1/4 or 3/8 inch). Applications. Model 7500 Pumps are designed for use in MBL lubricators with 1/2-inch rise cams. Durability. A hardened steel roller-rocker arm following a cam actuates the pump and reduces torque. The round sight glass is one-piece, injection-molded material that is impervious to ultraviolet rays and mineral and synthetic oils. Features and Benefits • Rugged construction for durability • Suction and gravity/pressure feed models available • Hardened cam rollers increase pump life • Pump output is easily adjustable • One-piece sight glass for fewer leak path and seal points
