Description
Oberdorfer N991 Nitrile Rubber Lip Seal, 2.2 GPM, 1/4 in. NPT Ports Bronze Gear Pump
Oberdorfer’s N991 Series pump housing and gears are made of top-quality bronze, and shafts are made of 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, and 150 PSI for oil and other lubricants. The maximum shaft speed is 1750 RPM.
Note: Pump only. Motor not included.
