Oberdorfer Gear Pump Model# N13HDL

Product Information


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.

FEATURES

  • All Bronze Castings and Stainless Steel Shafts
  • Sealing Arrangement Interchangeable in field with Proper Kit
  • Outboard Ball Bearing Support for Belt Drive Applications
  • Self Lubricating Carbon Bearings
  • Electric Clutch (Options)

DRIVE

DRIVE & ALIGNMENT- Direct drive is the recommended drivearrangement. This pump is suitable for belt drive applications without needing pillow block bearings to achieve acceptable pump life. Correct alignment is absolutely essential for satisfactory pump life. Recheck alignment after piping has been connected to the pump. Electric clutch versions available.

NOISE - Large gear pumps are inherently noisy due to metal to metal gear contact. Make installations far removed from offices or other relatively quiet people areas. Some noise reduction can be realized by lowering pump speed and use of isolation mounts and lines, usually the small amount of noise reduction achieved does not justify the effort and expense.

SUCTION LIFT

A rotary gear pump is capable of lifting water on the suction side as high as 20 feet. Though gear pumps are self-priming, a foot valve is recommended. For pumping water directly from streams or ponds, a wire mesh strainer must be used at the beginning of the suction line to prevent stones from entering the Pump. Strainer and foot valves are commercially available as combination units.
