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

Oberdorfer N992 Gear Pump Peo Brz 3/8" Buna Pump housings and gears are made of top quality bronze, shafts are 303 stainless steel. Bearings are designed of high performance carbon-graphite material selected for wear resistance and long service life. Gear pumps are positive displacement pumps. Each shaft revolution displaces a definite amount of liquid  relatively unaffected by the back pressure in the discharge line. Shaft speed and flow are directly proportional. Recommended pressure limits are 100 PSI for water and non-lubricants, 150 PSI for oil and other lubricants. The maximum shaft speed is 1750 RPM. FEATURES Rugged Corrosion Resistant Bronze Construction Compact Close-Coupled Design Stainless Steel Shafts Durable Bronze Helical Gears Provide Quiet Operation Process Lubricated Carbon Graphite Bearings O-Ring Cover Seal For Maximum Leak Protection Lip Seal or Mechanical Seal Easy Field Assembly to a Variety of Motor Frames - For Typical DC Motor Pump Units - see N992 DC For Compact AC Motor Pump Units. See Close Coupled Bronze Adapterless Rotary Gear Pumps. For Danfoss Hydraulic Motor Driven Pump Units. See Adapter 9960 For Bonze Pedestal Pumps. See Model N2000 For Close-Coupled Ductile Iron Pumps - See Model C992 LIQUIDS & TEMPERATURES These pumps are suitable for all liquids that are compatible with bronze. Most common liquids are water, oil, and mild chemicals in the pH range of 4 to 11. Viscous liquids require reduced shaft speeds of 1150 RPM or lower. (Consult factory.) Liquids containing solids, abrasives, powders, or paint pigments are definitely not recommended for gear pumps. If abrasives are unavoidable, use a very low shaft speed. See price book for the recommended liquid temperature range of lip and mechanical seals. If more extreme temperature conditions exist, factory should be consulted. Freezing of water-filled pumps can cause damage and must be avoided. Oils at low temperatures are very viscous requiring a lower speed or extra power. SUCTION LIFT As a general rule, the suction lift should be kept at an absolute minimum by placing the pump as close to the liquid source as possible. A gear pump in new condition can lift 20 feet of water in the suction line. A foot valve (preferably with built-in strainer) is recommended at the beginning of the suction line. For a first startup, the pump should be primed to avoid dry running. Minimum size of the suction pipe is the size of the pump inlet port. For longer suction lines (over 3 feet) or for viscous liquids, the pipe should be at least one size or two sizes larger than the pump inlet port. If the discharge line contains any throttling devices such as a shut-off valve, a spray nozzle or other restrictive device, it is necessary to have a relief valve in the system, which returns the liquid to the suction side or to the tank. The relief valve is also available as part of the pump itself (R-model pumps). However, built-in relief valves are only good for intermittent service. If used continuously, the pump will overheat. A built-in relief valve is strictly a safety device against overpressure. It will not work successfully as a pressure or flow control device. For this purpose a separate relief valve in the pressure line must be used. Unless otherwise specified, the pump motor unit is supplied by the factory for shaft rotation counterclockwise from shaft end. Reversing motor will reverse “in and “out” ports and also requires changing relief valve location. The relief valve is always on the inlet side of this pump series. The factory pressure setting is 50 PSIG. To increase pressure, turn the relief valve adjusting screw in a clockwise direction.

Oberdorfer 170M Cent Pump Peo Brz 3/4 Ports These Oberdorfer™ centrifugal pumps have a single open vane rotating impeller. Liquid enters at the center and is thrown outward radically 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 flow of these pumps can be conveniently controlled by a throttling valve in the discharge line. Horsepower demand will decrease as the pressure increases. Maximum horsepower occurs with a wide open discharge.   The lip seal is Nitrile with stainless steel spring reinforcement on a stainless steel motor shaft. The seal is friction press fit in a machined housing counter bore. Excessive system pressures above 15 PSI are not recommended as the seal could be forced out of the pump housing.   FEATURES Rugged Corrosion Resistant Bronze Construction Compact & Light Nitrile Lip Seal STD; Optional fluoroelastomer Lip TEFC Motors With Corrosion Resistant Passivated 316 SS Shafts 1/10 HP Permanent Magnet 12V, 24V, 32V DC Motors Rubber Base Grommets For Vibration Dampening Insulated Leads 1/13 HP Permanent Magnet 12V DC Motor (A95) Ideal for:   Marine Air Conditioning Engine Block Temperature Control Radiator & Heat Exchanger Circulation Baitwell Circulation DRIVE One of the outstanding features of this pump and motor unit is its compact D.C. motor size. Although small, adequate motor power is available.  Motors are available in 12, 24 and 32 VDC.   LIQUIDS & TEMPERATURES This pump is more than capable of pumping water, water solutions, and a wide range of commercial 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 increases.  Liquids heavier than water require additional horsepower in direct proportion to the increase in specific gravity.  Questions about the chemical compatibility of special liquids should be referred to the factory.      SUCTION LIFT These 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 the non-leaking foot valve for starting capability.
