A wide variety of motors are available and we can assemble for you.     APPLICATIONS / CHARACTERISTICS Oberdorfer™ centrifugal pumps have a single rotating metal impeller. Liquid enters at the center and is thrown outward radially by centrifugal force. The impeller is not in contact with other pump parts resulting in quiet, efficient, pumping action. The flow produced is not positive which permits the discharge line to be shut off completely without danger of overloading motors or bursting lines. Consequently a relief valve is not required. The liquid flow varies directly as 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. FEATURES Rugged Bronze Construction A Standard in the Marine Air Conditioning Industry Extremely Quiet Operation O-Ring Housing seal eliminates gasket problems Polytetrafluoroethylene (PTFE) Barrier Seal to protect motor bearings Handles Contaminated Liquids Discharge port orientation flexibility-8 positions Mechanical Seal - Carbon/Ceramic, Nitrile - standard, Fluoroelastomer (S10) optional, Polytetrafluoroethylene (PTFE)(S11) optional Pump Heads mount to standard footed Nema 56J Jet Pump Motors Shafts: 416 Stainless, Nickel Alloy, or 316 Passivated Stainless Multiple motor options available For Industrial Version - see Model 700 series DRIVE This close-coupled pump uses a standard NEMA C-Flange Jet Pump Motor with weld-on base and threaded shaft end to accept the pump impeller. Single phase motors are nonreversible and are wired for the proper pump rotation which is counter-clockwise looking at the inlet end of the pump. (See the dimensional drawing.) Three phase motors must be checked out for proper rotation when the pump is installed.  Interchanging of any 2 wires in a 3-phase system will reverse motor rotation.  LIQUIDS & TEMPERATURES The special pump alloys used provide corrosion resistance to many liquids including water, water solutions, and a wide range of commercial chemicals. Questions as to the chemical compatibility of special liquids should be referred to the factory. The pump uses a mechanical type shaft seal with a Nitrile rubber element. It is suitable for water, oils, and some mild solvents and it is limited to 212oF and 75 P.S.I. Fluoroelastomer (S10) seals and Polytetrafluoroethylene (PTFE) (S11) seals are available for severe solvents and difficult chemicals. Viscous liquids with a maximum viscosity of 2000 Saybolt Seconds Universal can be pumped. However, when pumping viscous liquids as compared with water, a reduction in flow and pressure occurs and the required horsepower rate increases.  Liquids heavier than water require additional horsepower in direct proportion to the increase in specific gravity. Liquids contaminated with small solids or abrasives can be handled, but a reduction in mechanical seal life must be expected.  SUCTION LIFT These centrifugal pumps are not self-priming. They must be installed below the liquid level so that the liquid flows to the pump by gravity (flooded suction). However, if a foot valve is used at the beginning of the suction line and all air is bled from the pump by manual priming, the pump will lift on the suction side up to 15 feet. Such a system relies entirely on a non-leaking foot valve for starting capability.   Will Handle Contaminated Liquids. Extremely Quiet.

Oberdorfer 300B Series Self Priming Centrifugal Pump FEATURES Pump Body: Bronze Ports: 1" NPT Flow: 22 GPM Max Pressure: 15 PSI Max, 35 feet of head Impeller: Centrifugal Shaft Seal: Mechanical Buna Seal Standard, Viton or Teflon Optional Shaft: Stainless Steel Standard, Monel Optional Motor / Drive: Attaches to NEMA C flange jet pump motors with threaded shaft of stainless steel or monel. We can supply additional motors and assemble if required.     APPLICATIONS / CHARACTERISTICS 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. FEATURES Self-Priming to 20 Feet Suction Lift Rugged Bronze Construction Ideal for marine service (air conditioning, bilge, and sea water recirculating). O-Ring Housing seal eliminates gasket problems Auxiliary Connections - for convenient priming and draining Multiple Mechanical Shaft Seal Options -for various applications Pump Heads mount to Standard Footed Nema 56J Jet Pump Motors Shafts : 416 Stainless, Nickel Alloy, or 316 Passivated Stainless Multiple motor options including Explosion Proof For Pedestal Style, see 30PB Optional Lifting Handle 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.  LIQUIDS & TEMPERATURES Capacity - Water 60o F - Gallons Per Minute Maximum lift without foot valve is 10 feet. 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. SUCTION LIFT Up to 22 gallons per minute water flow and suction lift of 15 feet without a foot or check valve (25 foot suction lift using a foot or check valve and a filled inlet line). A 1/2” pipe plug on the tank top is for initial filling of priming chamber and inlet line--pump priming is automatic thereafter.      300B is Oberdorfers - Self Priming Centrifugal Pump Head Only Bronze
