Aluminum and plastic rotary and piston barrel pumps and drum pumps for agricultural and chemical applications, oils, fuel oils, brake fluid, antifreeze and other liquids compatible with their individual materials of construction. Suitability for the application should be determined by actual use and is the full responsibility of the customer. No warranty, expressed or implied, can be extended by equipment manufacturer where failure is caused by chemical attack on pump materials. Temperature, aeration, concentration, and other factors may change the effect of the specific fluid on the pump materials. Data shown is based on the results at ambient temperatures, unless otherwise noted.
A gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for pumping oil. Gear pumps are also widely used in chemical installations to pump fluid with greater than viscosity. There are two main variations; external gear pumps which use two external spur or helical gears, and internal gear pumps which use an external and an internal spur gear. The Oberdorfer Pumps are of the external helical gear design. Gear pumps are positive displacement, meaning they pump a constant amount of fluid for each revolution.
