Gear Pumps

We might not have invented the gear pump, but when compared to other gear pump manufacturers, you could say we’ve perfected it.  The Oberdorfer™ name was founded on our line of bronze gear pumps and over time we’ve led the industry in quality and innovation.  We offer helical gearing, a method in which the gears are cut on angle to the face of the gear.  This allows for more material contact, resulting in a greater degree of material customization and hydraulic range and a quieter running pump. So, whether your design calls for an external gear pump, pedestal mount, clutch driven, motor mount or stainless steel gear pump, you can rest assured that our family of gear pumps is as diverse as the applications in which they’ve been used – for more than 100 years.

 

Gear Pumps N991

Pump housings and gears are made of top quality bronze, shafts are 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 backpressure in the discharge line. Shaft speed and flow are directly proportional.
