OBERDORFER N9000L PEDESTAL MOUNT GEAR PUMP Pump housings and gears are made of top quality bronze, shafts are 303 stainless steel. Bearings are made 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 backpressure in the discharge line. Shaft speed and flow are directly proportional.   DRIVE Either direct drive with flexible coupling or pulley drive can be used. Make sure both flexible coupling halves are properly aligned. When using a pulley, do not over tighten the belt. Also, to absorb belt side thrust at higher pressures and larger size pumps, an external ball bearing support is recommended - consult factory.   LIQUIDS & TEMPERATURES Service life will be increased substantially if the liquid pumped is clean and has some degree of lubricity. These positive displacement pumps have tight tolerances. Fine abrasives like sand, silt, or powders in suspension will accelerate pump wear and reduce throughput. Liquids compatible with bronze and stainless steel can be pumped providing proper seal has been specified (see chemical compatibility or check factory). When possible, flush the pump after each usage. Temperature extremes are detrimental to service life and should be avoided. Basic metals of construction allow a temperature range of -40°F to 400°F. Some lip and mechanical seal elastomers have a limit of 212°F. Allowing a liquid to freeze in the pump can cause damage.   SUCTION LIFT Close tolerances and the positive pumping action make the rotary gear pump capable of lifting water on the suction side as high as 20 feet. Though gear pumps are self priming, a foot valve is recommended. If possible, wet the gears with liquid to be pumped for the first dry start. Liquid retained in the system and gear chambers serves to “wet” the pump on subsequent starts.

PSI: 100 • Suction lift to 19.5 ft.* • Maximum viscosity to 100,000 SSU at reduced speed (max. input torque of 160 in.-lbs.) • Housing gasket: Vellomoid • Construction: Cast Iron housing, Steel gears, Steel shafts • Shaft Seals: Synthetic Braided compression packing with Teflon dispersion • Shaft Bearing Journals: Grease lubricated Cast Iron • Temperature range: -20 to 210° F • Maximum working pressure: 130 PSI • Pumps can operate bidirectionally (reversible) This Oberdorfer CB9000L is the drop in replacement for models C4K and C4V. It can also be considered as replacements for models 4KHK4 and 4KHJ7. This self-priming, positive displacement, external rotary gear pedestal pump is ideal for oil based fluids in a wide range of light-duty commercial, industrial, marine, and agricultural applications. It is for use with particulate free and non-abrasive high lubricating oil-based fluids compatible with iron and steel. Not to be used with water-based fluids. Line mounted pressure relief valves are recommended to protect downstream equipment. The pump should be mounted on a rigid base and properly aligned with the motor. Direct drive via flexible shaft coupling is the preferred method. When a belt drive is needed, additional support is necessary to absorb the added pulley load.

Oberdorfer N991 Gear Pump Peo 1/4" Brz 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 backpressure 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. Close-coupled gear pumps are normally supplied with a Nitrile lip seal. A lip seal made of fluoroelastomer is available as an option. For a fluoroelastomer Seal, add S5 to the pump model number.   FEATURES Rugged corrosion resistant bronze construction Compact close-coupled design Stainless steel shafts Durable bronze spur gears Process lubricated carbon graphite bearings O-ring cover seal for maximum leak protection Nitrile Lip Seal -standard Easy field assembly to a variety of motor frames For typical DC motor pump units - see N991-32 DC For compact AC motor pump units - see Close Coupled Bronze Adapterless Rotary Gear Pumps For bronze pedestal pumps and mechanical seal styles - see model N1000 DRIVE Close-coupled pumps are mounted directly to the electric motor by means of a suitable adapter bracket. The pump drive shaft is connected to the motor shaft by a flexible coupling.   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. The recommended liquid temperature range is from 32o F to 140o F for best pump life. 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 start-up, 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.
