The Oberdorfer™ name is trusted by hundreds of leading OEMs. Our reliability and simplicity make aftermarket integration into your existing systems seamless. Oberdorfer™ is your industrial pump solution.
What do embalming, truck driving and aviation have in common? The answer is an Oberdorfer™ pump. We’ve been keeping the wheels of commerce turning and we have no plans to stop. Thanks to our multiline product family and more than 100 years of pumping innovation, no matter your application, there’s an Oberdorfer™ product that can be easily integrated into your system.
You want a brand you can trust on the water and Oberdorfer™ pumps deliver efficiency and peace of mind. Our centrifugal bronze pumps with Nickel Alloy Shaft are ideal in marine applications such as air conditioning, bilge and seawater recirculation. Many of the leading marine manufacturers and boat operators have come to rely on Oberdorfer™ for fuel transfer and conditioning, ballast trimming and oil transfer.
Oberdorfer™ pumps are the first choice of OEMs and engineers in glycol transfer applications. Whether used as a precursor in the production of polymers, in refrigeration or dehydration systems, these pumps are reliable and built to ensure consistent pressure and control levels across a wide variety of chemical processing applications. Oberdorfer™ should be your first choice in a system that requires a coolant pump.
Tailored specifically for wear resistance and long life in pressurized heat transfer oil circulation service for plastic injection molding and other industries. They are industrial units designed to handle fluctuating temperature cycles pumping Therminol ®, Dowtherm ® , Paratherm ® and others at elevated temperatures to 450 °F, at pressures up to 100 psi, and at shaft speeds to 1750 RPM. Shafts are hardened steel. Gears are high-strength durable Fatigue Proof ® steel. Rugged ductile iron housings. High-grade carbon-graphite bushing style bearings and thrust plates are used. The shaft seal is a bellows style mechanical seal with fluoroelastomer elastomer bellows and o-ring and with carbon and ceramic wear faces. No stuffing box cooling necessary. Contact Factory for 550 °F option.
These pump housings and mounting brackets are made from cast aluminum or bronze alloy. The rotor is made from stainless steel with a hard chrome plate for improved wear properties. The stator is made from molded Nitrile. The mechanical seal is a carbon and ceramic rotary face type for positive sealing.
CHEMSTEEL™ pumps are designed to handle common and highly corrosive liquids that must be pumped under pressure. Manufactured to extremely precise tolerance, the CHEMSTEEL™ pump line prevents system contamination while maintaining the purity and integrity of the liquid being pumped. Its rugged, three-section, o-ring sealed thru-bolt construction provides ease of servicing and parts replacement. Helical gearing offers noise reduction by as much as 10db, while the tandem pumps double the output flow for a single fluid, or with isolation, handle other fluids in direct ratio to the first. Additionally, CHEMSTEEL™ pumps offer bi-directional operation for applications requiring reversing flow.
The carbonator motor mounting uses a circular clamp, similar to a hose clamp, as means of attaching the pump to a specially machined hub on the motor. This concept was first developed for the vending machine industry to pump carbonated beverages in soft drink dispensers. The main advantages are compactness and economy due to the elimination of the adapter casting. Carbonator motors are readily available from electric motor distributors.
Pumps are the Stainless Steel version of the Industry-Proven Bronze Pedestal Gear Pump N4000L specified by many leading maple syrup filter press equipment manufacturers. Handles abrasive sugar sand and filter aide. These versatile pumps can be operated in either rotational direction and can be installed in any plane. All materials of construction are suitable for food service use. Flush new Factory Supplied pumps thoroughly before use.
Tailored specifically for wear resistance and long life in lubricating fluid service. They are designed to handle a wide range of fluids at temperatures to 200°F, at pressures up to 150 psi, and at shaft speeds to 1750 RPM. Viscous liquids require reduced shaft speeds. Standard Lubricating Fluid Service: Shafting is 303 stainless steel, gearing is ferrous (optional 416SS gears). Rugged ductile iron housings. High grade carbon-graphite bushing style bearings are used. The Standard Mechanical Shaft Steel is a stainless cased Nitrile elastomer bellows and oring with carbon and ceramic wear faces. An optional fluoroelastomer mechanical seal with carbon and ceramic wear faces is also available. Recommended liquid temperature range is 32oF to 200oF.

Pump housings and gears are made of top quality bronze, shafts are 303 stainless steel. Bearings are made 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.
