Meter-Flo® Pumps Direct-drive, smoothly operating pumps ideal for applications requiring con inuous delivery t of hydraulic or lube oils. DESCRIPTION Meterflo gear-type pumps are available in 11 models with displacements from 9 to 161 in3 (147 to 2,638 cm3) per minute at 1,140 rpm, and 14 to 245 in3 (229 to 4,015 cm3) per minute at 1,725 rpm. They are designed for pressures up to 1,500 psi (103 bar). Positive displacement helps assure constant delivery of proper volume. Standard SAE 4-bolt mounting simplifies installation. Adjustable pressure relief valve protects pump against overload conditions. (See caution note, page 2) CROSS SECTION OF PUMP Match-ground heat-treated steel gears are enclosed in a rigid, cast-iron housing to assure dependability and long life. Meterflo pumps are available with a special coupling that allows easy replacement of older Meterflo pumps. (See ordering information for details). As the gears come out of mesh, oil is drawn into the suction side (S) of the pump, filling the spaces between the gear teeth. As the gears rotate, oil is carried between the teeth and the gear housing until it reaches the discharge port (D). As gears mesh, they force out the oil.
