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.

GENERAL INFORMATION
TYPICAL PUMP INSTALLATION
Oberdorfer has a long history of supplying pumps to the
welding machine industry. Ever since the Heliarc welding technology 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 retrofit for Miller Electric Mfg. Co.
The reasons for the wide acceptance of Oberdorfer
pumps in the welding machine industry are reliability, long service 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.
