Industrial
Rotary Gear Pumps

Flow:
 1-175 GPM (3 - 662 LPM)
Pressure:
 0-150 PSI (0 - 10.3 BAR)
Performance:
 Positive displacement. Little flow decrease with pump pressure increase. Flow increases with speed increase.
Suction Lift (water):
 0-20 Ft. below pump level (0-6.1 meters)
Liquid Cleanliness and Viscosity:
 Close tolerances require clean liquids. Viscous liquids require lower pump speeds.
Liquid Compatibility:
 Most common liquids and compatible chemicals.
Noise:
 Metal to metal gear noise very evident. metal to plastic gear noise evident.
Power Required:
 Power demand increases with speed and pressure.
Discharge Line:
 Positive displacement relief valve necessary to shut off.
Bearing Lubrication Required:
 Carbon bearings - No
Bronze bearings - No
Temperature:
 Carbon bearings: - 40 to 300 degrees F (-40 degrees C to 150 degrees C)
