- 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 are normally supplied with a Buna N lip seal. A lip seal made of FKM(R) is available as an option. For a FKM(R) Seal, add S5 to the pump model number.
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.
