OBN2000R-50 Oberdorfer Gear Pump

OBN2000R-50 Oberdorfer Gear Pump

FEATURES:

• Bronze Corrosion Resistant Castings.
• Special Cast Bronze Gears.
• Stainless Steel Shafts & Fasteners.
• Formed Ring Seal Packing (Lip & Mechanical Seals on.

DRIVE:

Either direct drive with flexible coupling or pulley drive can be used. Make sure both flexible coupling halves are properly aligned. When using a pulley, do not over tighten the belt Also, to absorb belt side thrust at higher pressures and larger size pumps.

LIQUIDS AND TEMPERATURE:

Service life surely will be increased substantially if the liquid pumped is clean and has some lubricant. These positive displacement pumps certainly have tight tolerances. Fine abrasives like sand, silt, or powders in suspension will accelerate pump wear and reduce throughput.

Liquids compatible with bronze and stainless steel also can be pumped providing proper seal. When possible, flush the pump after each usage. Extreme temperatures are detrimental to service life so, should be avoided.

Basic metals of construction allow a temperature range of -40 to 400 °F. Some lip and mechanical seal elastomers have a limit of 212 °F. (see engineering data or check factory). Liquid to freeze in the pump can cause damage.
