Bronze Centrifugal Pump Pedestal

Oberdorfer 50P-15

Bronze Centrifugal Pedestal mounted for long coupling to customer drive. The liquid flow is proportional to the pump speed--the higher the speed the greater the flow. Horsepower required varies directly as flow and pressure. Maximum horsepower is required with a wide open discharge line. This is the point of maximum flow. With a throttled discharge, the flow decreases at a greater rate than the pressure increases thereby requiring less horsepower at the higher pressures. This is known as an “unloading” feature of the pump. The pedestal centrifugal pumps can be direct driven by electric motors at either 3450 R.P.M. or 1725 R.P.M. Performance for both speeds are shown in the curves above. The 50P pedestal centrifugal pumps can be pulley driven at any desired intermediate speed.
  • All Bronze
  • Marine, Flat saws
  • Carbon Face Mechanical Pump Seal
  • Cast Iron bearing pedestal with ball bearings for pulley drive

  • Extremely Quiet
  • A Standard in the Marine Air Conditioning Industry
  • Counter-Clockwise Rotation facing front of pump

Heavy liquids can be pumped; however, they demand morehorsepower in direct ratio to the weight of water. For example, carbontetrachloride has a specific gravity of 1.6 which means it is 1.6times heavier than water and the horsepower required is 1.6 timeswater horsepower. Because centrifugal pumps are more efficient at higher shaftspeeds, pumping of viscous or thick liquids is difficult.

Other This centrifugal pump is not self priming. Normally these pumps must be installed below the liquid level so that the liquid flows to the pump by gravity. However, if a foot valve is used at the beginning of the suction line and all air is bled from the suction line and pump by careful manual priming, these pumps will lift liquid on the suction side up to 15 ft. Such a system is only as positive as the ability of the foot valve to seal and keep the suction line and pump full of liquid. If the foot valve should leak, the pump will not prime.
