Heliarc Series

Heliarc Series

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 circulate 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.
