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 N91

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.

Gear Pumps N91060GKC

The rotary gear pump features an all bronze design and 303 stainless steel shafts with options of non-metallic gears and a variety of shaft seals. The built-in relief valve is available in two options; internal recirculation to suction side or external connection for return line to supply tank.

Gear Pumps N970

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 back pressure in the discharge line. Shaft speed and flow are directly proportional.

Testimonials

“I am sending you this email to tell you how happy my customers in the Oilfield Services have been over the past two years with your CHEMSTEEL™ brand of pumps, the S21416CZ, S92316CZ and S93516CZ in particular. They are using the S214 pumps for 6GPM chemical injection, in place of the small triplex pumps they had been using for years, and the S923 pumps for 14GPM chemical injection also along with the S935 model for 22GPM for friction reducer. The larger pump is replacing PC pumps that they have been using. I am happy to say that they have told me they like the way your pumps operate and don’t have to replace parts nearly as often as they used to do with the other lines of pumps they were using. I have even been able to sell them some of your pumps for new chem-add pump trucks as well as new blender pump units. Looking forward to a long and prosperous relationship with you over the next years.”

“Oberdorfer™’s CHEMSTEEL™ line of alloy and non-metallic gear pumps has been a tremendous asset for our company. We have solved several customer applications challenges with this versatile, economical, yet rugged pump. The folks at Oberdorfer™ have made CHEMSTEEL™ pumps the most comprehensive and versatile chemical-duty gear pump available in the market. The choice of seals (or magnetic coupled), bearing materials and adapters for mounting allow for countless configurations to offer our customers. CHEMSTEEL™ is truly a winner. And will be for our company for years to come!”

“I just wanted to say thank you for the help on the sulfuric acid application from a couple of months ago and update you on the outcome. To date there has been no downtime in that area of the plant. The CHEMSTEEL™ pump has worked great. If you recall, it was a difficult application. Our customer had tried several different styles of pumps with varying degrees of success. It seemed with each pump they would solve one problem only to find another. After they got us involved and we got you involved, the pieces started to fall into place. They really like the simple, sturdy design and small footprint of the CHEMSTEEL™ pump. The added control that they have now over their process due to the range of flow has just added value to the product. We have another satisfied customer and you helped Industro live up to its motto – INDUSTRO: ‘People and things that work.’ ”
