Oberdorfer Centrifugal Pump Model# 750B-T28

Product Information


This close coupled style bronze self-priming centrifugal pump is equipped with high quality ball bearings permanently filled with grease for maintenance free operation. The main shaft seal is a mechanical face type seal of proven reliability. Unlike positive displacement pumps centrifugal pumps have larger internal clearances as the pressure is generated by centrifugal force and high liquid velocity. These pumps can handle impurities in the liquid and the flow in the discharge line may be throttled or shut off without the need for a relief valve.

This pump must be operated with the shaft in a horizontal position as shown in the picture. Before initial start-up, the pump must be filled with liquid through the priming plug opening on top of the pump body. It will be self-priming thereafter, even without a foot valve in the suction line. However, a foot valve is always recommended to insure immediate liquid flow at startup.

FEATURES

  • All Bronze Construction
  • Self-Priming to 20 Ft. Suction Lift
  • Seal Options Available for Solvents and Mild Chemicals
  • Pump Heads can be Field Mounted to Standard Nema C Jet Pump Motor with Threaded Shaft
  • Base May be Mounted to Motors with Weld-On Feet
  • Available with Nickel Alloy Shaft for Marine Applications

DRIVE

Centrifugal pumps are designed for single rotation and are non reversible. Standard rotation is counter clockwise looking at the pump inlet port (clockwise facing pump shaft). Close coupled centrifugal pumps may be driven by a variety of power sources such as electric motors, hydraulic motors or air motors. Self priming centrifugal pumps must be operated in the horizontal position. Pumps with polyphase motors must be checked for proper shaft rotation at the time of installation. Rotation must correspond with directional arrow on pump body.

LIQUIDS & TEMPERATURES

Bronze pumps are suitable for most common liquids in the pH range from 4-11. If in doubt consult with factory or check the Oberdorfer™ Chemical Resistance Guide booklet. The temperature limit for bronze pumps is 212F. Higher temperatures are possible with Fluoroelastomer or Polytetrafluoroethylene (PTFE) seals. Centrifugal pumps are not well suited for pumping viscous liquids. Viscosities up to 2000 SSu may be handled resulting in reduced performance and efficiency.

Pump seal is mechanical carbon face type mated to ceramic wear face for maximum durability. Other seal components are made of Nitrile with low swell characteristics for compatibility with a wide range of liquids including many chemicals and solvents. The standard mechanical shaft seal has a Nitrile rubber element. Fluoroelastomer and Chemlon Polytetrafluoroethylene (PTFE) seals are available to handle strong solvents and chemicals
