Applications
There are many applications that the Oberdorfer N9933 are used in. These pumps are suitable for all liquids that are compatible with bronze. Most common liquids are water, oil, and mild chemicals in the pH range of 4 to 11. Viscous liquids require reduced shaft speeds of 1150 RPM or lower. Liquids containing solids, abrasives, powders, or paint pigments are definitely not recommended for gear pumps. If abrasives are unavoidable, use a very low shaft speed. These gear pumps are used in Waste Water Effluent Sampling to draw samples from canals and waste areas to test the cleanliness of the water. They are used in Day Tank Diesel Transfer Systems, and have been one of the leading Diesel fuel transfer pumps for over 100 years. The purity of the fuel is an important feature in prolonged engine life and high performance. Fuels must provide satisfactory combustion without creating additional pollutants that can damage the engine. Oberdorfer Pump housings and gears are made of top quality bronze, shafts are 303 stainless steel. Bearings are designed of high performance carbongraphite material selected for wear resistance and long service life. These features make Oberdorfer pumps your best choice to keep your engines running longer and more efficiently. This pump is also the best solution for General Water Service, Chilled and Hot Water Systems, HVAC Industrial Processes, Municipal Drinking Water, Sprinkler and Irrigation Systems. NOTE Thick or viscous liquids are not recommended for centrifugal pumps. Because centrifugal pumps are more efficient at higher shaft speeds, pumping of viscous or thick liquids is difficult. It is possible to lose as much as 40 percent pump performance when attempting to pump liquids of viscosity equal to S.A.E. 30 oil at room temperature. S.A.E. 30 oil at room temperature has a viscosity of 2000 Saybolt Seconds Universal.
