Oberdorfer N999R-C81
Bronze 12v DC gear pump mounted to a 1200rpm 1/4 HP motor. Pump has
relief valve.
Features N999 Series:
- Compact design eases installation and use in limited space areas.
- Construction is bronze and stainless steel wetted components.
- Close tolerance design allows for consistent performance
- Spur gears for quiet operation.
Pump housings and gears are made of top quality bronze, shafts are 303 SS. 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 100PSI for water and non-lubricants, 150PSI for oil and other lubricants. The maximum shaft speed is 1750 RPM.
Close coupled gear pumps are normally supplied with a Buna N lip seal. A lip seal made of FKM(R) is available as an option. For a FKM Seal, add S5 to the pump model number.
These pumps are suitable for all liquids that are compatible with bronze. Most common liquids are water, glycol, oil, and mild chemicals in the pH range of 4 to 11. Liquids containing solids, abrasives, powders, or paint pigments are definitely not recommended for gear pumps.

| Other | 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 builtin 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. Motor is a modified 48 frame. |
