Oberdorfer # R10417CC Stainless Steel Chemsteel Gear Pump

The Oberdorfer R10417CC is a Chemsteel Gear Pump End only, with 316 Stainless Steel Housing, 316 Stainless Steel shafts, PTFE Teflon Drive Gear, PTFE Teflon Idle Gear, Carbon Bearings, PTFE Teflon/Carbon/Sil-Carbide/316SST Single Wedge Mechanical Seal with 1/2 inch FNPT Ports, replacement pump end only without a Motor. This rotary gear pump is of the external gear positive displacement type, displacing a finite volume of fluid with each shaft revolution. As such, capacity varies in direct proportion to pump speed. This pump is rated for operation at a maximum shaft speed of 1750 RPM. This pump can handle viscous fluids to 100,000 cps (462,000 SSU) at reduced shaft speeds, with flow rates to 2 GPM GPM, and a suction lift capability to 20 feet (6.1 meters) for new pumps. It has rugged, three-section, o-ring sealed thru-bolt construction provides ease of servicing and parts replacement. This pump has precision investment castings of type 316 Stainless Steel which is an all purpose austenitic stainless alloy, with excellent corrosion resistance, and is the premium choice of all 300 series stainless alloys. Plastic gears are quiet, efficient, use less power and give longer service life. The precision machined Helical non-metallic gears of PTFE Teflon plastic offer noise reduction by as much as 10db. Plastic on Plastic gear combinations are limited to a maximum differential pressure of 50 PSI. Pump life will be extended and noise reduced by this plastic on plastic gear combination vs two metal on metal gears. This pump features slotted bearings to lubricate the shaft and gear surfaces, and hydraulic porting to balance axial thrust and to reduce wear. The Carbon sleeve bearings and are for maximum chemical resistance and high load capacity as the carbon bearings function as thrust flanges and wear plates. They are full size bearings that match the gear diameter and eliminate the need for separate wear plates. This pump is equipped with a mechanical seal of the standard wedge style. It can be expected to provide long and trouble free service provided the seal materials are compatible with fluid being pumped and properly applied to the service. Adequate cooling and lubrication of the seal is required to perform properly. Do not run the pump dry or the seal will burn up and keep abrasives out of the seal area. Ensure that the seal surfaces are wet prior to start-up and the pump and driver are properly aligned. The o-rings are Teflon encapsulating, silicone and provide elastic memory to assure an effective long lasting seal. The upper shaft configuration lends itself to in-line pump seal maintenance without the leakage of trapped chemicals from an incompletely drained pump. Ample port sizing of 1/2 inch FNPT ports reduce the likelihood of cavitation when inlet pressure is marginal. Additionally, this pump offers bi-directional operation for applications requiring reversing flow, and will perform equally well in either direction. To change flow direction effectively reversing the suction and discharge ports, simply switch driver rotation by following motor wiring diagram instructions. The positive displacement principle requires the installation of a pressure relief valve protecting the pump against over pressure. Over pressurization can occur when a valve is closed or a blockage occurs.
