Oberdorfer N999S5-EXP

1/2 gpm pump with EXPlosion proof motor.

Features N999 Series:

  • Compact design eases installation and use in limited space hazardous areas.
  • Construction is bronze and stainless steel wetted components.
  • Close tolerance design allows for consistent performance
  • Helical gears for quiet operation.

Pump housings and gears are made of top quality bronze, shaft is 303 SS. Bearings are designed 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. Recommended pressure limits are 100PSI for water and non-lubricants, 150PSI for oil and other lubricants. The maximum shaft speed is 1750 RPM.

Close coupled gear pumps supplied with a lip seal made of FKM(R).

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. Liquids containing solids, abrasives, powders, or paint pigments are definitely not recommended for gear pumps.
