Why Gear Pumps?
• Gear pumps are an ideal choice for viscous products. • Gear pumps lose performance gradually, and generally won’t fail catastrophically. • Since they are positive displacement, the flow rate degradation is directly proportional to TDH. • Gear pumps don’t shear fluid as much as other pump technologies. • Gear pumps are essentially pulseless positive displacement pumps. This makes them ideal for pulse sensitive applications or where you need to install a flowmeter near the pump output. Why Oberdorfer Centrifugal Pumps? • Quiet operation, longer gear life, and less product shear from helical gears • Longer bearing life from slotted bearing surfaces which balances axial load • Reduced NPSHr, and greater installation flexibility from larger port size • Better sealing and no cold flow with TFE Encapsulated o-rings. This reduces the need for re-torquing> at start-up, longer seal life, and reduces head related shrinkage of the pump body • Reduced likelihood parts will get damaged during pump
