Oberdorfer Pumps - N1000R39 - Oberdorfer Pumps N1000R39, Acrylonitrile-Butadiene

ITEM #: 10640636
Oberdorfer has a long history of supplying pumps to the welding machine industry. Ever since the Heliarc welding tech- nology was developed, Oberdorfer pumps were used to circu- late cooling liquid to the welder’s torch.
Pump and electric motor are usually mounted on top or on the side of the coolant tank. A pressure relief valve built into the pump returns excess liquid directly to the tank rather than to the suction side of the pump, thus avoiding heat build-up in the pump.
Pump models N1000R39 and N1000R-66* are coupled to the electric motor with a flexible coupling. The N95060GEC03 and N95060GFC01 models are close-coupled to a carbonator motor by a circular clamp arrangement, offering a space-saving, compact design alternative. Pump model N95060GE is a retro- fit for Miller Electric Mfg. Co.
The reasons for the wide acceptance of Oberdorfer pumps in the welding machine industry are reliability, long serv- ice life, and ease of maintenance. The pumps depicted on this page are being produced in quantities for several welding machine manufacturers in the U.S.A.
PUMP MAINTENANCE AND REPAIR
Oberdorfer gear pumps are essentially maintenance-free. If the pump is to be shut down for an extended period of time, it should be flushed thoroughly and filled with lubricating oil.
As a general rule, it is seldom economical to repair a worn out gear pump. However, if the gear chamber inside the pump body is still in good condition, the replacement of all interior parts by use of a repair kit may restore up to 80% of the original pump performance. Repair kit numbers and parts contained in each kit are listed on the parts lists on the reverse side.
