Oberdorfer

Oberdorfer Pumps has been manufacturing high-quality, dependable\npumps for over 100 years. We manufacture gear pumps, centrifugal\npumps, rubber impeller pumps, progressive cavity pumps, and roller\npumps. Positive displacement BRONZE gear pumps. Little flow\ndecrease with pump pressure increase. Flow increases with speed\nincrease. Flow from 1-175 GPM (3 - 662 LPM)and pressures from 0-150\nPSI (0 - 10.3 BAR). Pump housings and gears are made of top quality\nbronze, shafts are 303 stainless steel. Bearings are designed of\nhigh performance carbon-graphite material selected for wear\nresistance and long service life. Gear pumps are positive\ndisplacement pumps. Each shaft revolution displaces a definite\namount of liquid relatively unaffected by the back pressure in the\ndischarge line. Shaft speed and flow are directly proportional.\nRecommended pressure limits are 50 PSI for water and\nnon-lubricants, 75 PSI for oil and other lubricants.The maximum\nshaft speed is 1725 RPM. As a general rule, the suction lift should\nbe kept at an absolute minimum by placing the pump as close to the\nliquid source as possible. A gear pump in new conditioncan lift 20\nfeet of water in the suction line. A foot valve (preferably with\nbuilt-instrainer) is recommended at the beginning of the suction\nline. For a first start-up, thepump should be primed to avoid dry\nrunning. Minimum size of the suction pipe is thesize of the pump\ninlet port. For longer suction lines (over 3 feet) or for\nviscousliquids, the pipe should be at least one size or two sizes\nlarger than the pump inletport.\n\n

  • SM103 Magnetic Drive

    Designed to handle highly corrosive liquids that must be pumped under pressure. The Chemsteel pump prevents system contamination while maintaining the purity and integrety of the liquid being pumped. Key attributes include: Slotted bearings to lubricate shaft and gear surfaces. Hydraulic porting to balance axial thrust and to reduce wear. Ample port sizing to redice the likelihood of cavitation when inlet pressure is marginal. Effective housing seals with elastic memory prevent leakage of corrosives. Recirculation...

  • ChemSteel Chemical Gear pump

    Chemsteel chemical pumps are designed to handle common and higly corrosive liquids that mustbe put under pressure. The Chemsteel pump line prevents system contamination while maintaining the purity and integrity of the chemical liquid being pumped. 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. Gear/bearing design allows for "trimming" for optimizing the pump's...
