Roper # 1AP03 Gear Pump

The Roper 1AP03 is a Cast Iron pedestal Gear Pump, bare shafted pump end, with Lower Drive shaft configuration, Hardened Steel Gears, replacement pump end only without a Motor. This pump is a pump end only, for close or long coupling to motors, and is designed to operate at standard motor speeds, with provisions for flange or foot mounting. The internal bearings are lubricated by the fluid being pumped, and with only two moving parts, and idle gear and a drive gear, the pumps run quietly. They are manufactured and assembled with close tolerances, and regularly tested to insure dependable performance. The pump is factory assembled for clockwise rotation (facing the pump drive shaft end), most may be reassembled for operation with equal efficiency in a counter-clockwise rotation. All pump body castings are cast iron, for a precise, rugged, maintenance-friendly design. This gear pump has bi-directional rotation, with quiet-running helical gears precision machined to insure proper meshing, reduced friction and vibration, quiet efficient operation and long life. Four heavy duty sleeve bearings give positive support to pumping gears and insure long, efficient service. The 4 pump bearings are special wear-resistant, high-lead bronze with long-lasting bearing surfaces. (Iron and carbon bearings are available.) Large, hardened steel dowel pins insure positive alignment between the faceplate, case, and backplate. This pump end does not include a motor and is just the bare shafted pump end only. Complete pump and motor assemblies can be close coupled with a motor bracket and electrical motor, or fabricated with a pump, coupling, coupling guard, motor, and baseplate. The maximum temperature for this pump is 250 F.
