Oberdorfer Pumps

Oberdorfer manufactured its first bronze gear pump over 100 years ago. Since then, Oberdorfer Pump, a division of Gardner Denver Corp., has been manufacturing high quality gear, centrifugal, rubber impeller, progressing cavity and roller pumps to industries spanning from marine to industrial to agricultural to chemical processing. Proudly manufactured in the USA Oberdorfer has a strong history in meeting and exceeding fluid handling requirements.

Oberdorfer Bronze Gear Pumps

Oberdorfer was founded on their line of bronze gear pumps and over time they have led the industry in quality and innovation. They 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 bronze gear pump, you can be rest assured that Oberdorfer's family of gear pumps is as diverse as the applications in which they've been used – for more than 100 years. Pump housings and gears are made of top quality bronze, and shafts are 303 stainless steel.

Oberdorfer Bronze Centrifugal Pumps

Oberdorfer Centrifugal pumps are of the single stage, end suction, overhung type. The different Centrifugal pump models use open vane style and enclosed style impellers. Centrifugal pumps convert driver energy to kinetic energy in a liquid by accelerating it to the outer rim of a revolving impeller. Since the amount of energy given to the liquid corresponds to the velocity at the impeller's vane tip, the faster the impeller revolves (or the bigger the impeller is), the higher the velocity of the liquid at the vane tip and the greater the energy imparted to the liquid. In comparison to positive displacement devices, centrifugals are quieter and require no relief valve to protect the pumps from pressure build-up. Oberdorfer Centrifugal metal pump housings are made of top quality rugged cast bronze or light weight corrosion resistant cast aluminum. Shafts are corrosion resistant stainless steel or monel. Oberdorfer Centrifugal Pedestal Pumps use heavy duty "lubricated for life" ball bearings suitable for pulley loads. Most of the Oberdorfer Centrifugal Close Coupled pumps are designed to fit jet pump C faced motors; relying on the motor bearings to support pump loads.
