1/3HP 12V DC REVERSIBLE
Oberdorfer N992Q-01F94
12V DC Gear Pump with housings and gears are made of top quality
bronze; shafts are from stainless steel 303. Continuous Duty gear
pump fitted with 12V DC motor. Bearings are designed of high
performance carbon-graphite material selected for wear resistance
and long service life. Includes relief valve in pump head.
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 lubricants. Maximum shaft speed is 1750 rpm.
A relief valve is necessary in the system if the discharge line contains any throttling devices, such as a shut-off valve, a spray nozzle or other restrictive device. This will return 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. 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.
Service life will be increase substantially if the liquid pumped is clean and has a lubricity value. These pumps have extremely close tolerances.
DC motors feature Permanent Magnet Rigid Base Motors, made by Leeson in the USA. Compact DC portable units convenient for on site servicing of vehicles, machinery and field equipment. For pumping oil direct from crankcase or oil reservoir, drums, containers, transfer diesel fuel to vehicles, pumping other liquids and chemicals compatible with materials of construction. Basic metals of construction allow temperature range of -40ï½° to 250ï½°F.

| 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 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. |
