Performance:Positive displacement. Little flow decrease with pump pressure increase.
Flow increases with speed increase. Power: Power demand increases with speed and pressure.
Suction Lift (water): 0-20 ft. below pump level (0 - 6.1meters)
Liquid Cleanliness and Viscosity: Close tolerances require clean liquids. Viscous
liquids require lower pump speeds.
Liquid Compatibility: Petroleum products, solvents and fuel oils, soaps, coal tar, asphalt, sealers, resins,non-corrosive liquids, liquid propane.
Noise: Helical gear design quiet.
Discharge Line: Relief valve necessary if flow is shut off.
Temperature: -40 degrees F. to 250 degrees F. (-40degrees C to 122 degrees C)
Seal Arrangement: Mechanical or packing
Type: Close coupled & Pedestal

The Performance curve link here is a chart for all the pump sizes. On the individual pump model pages they contain the flow curve for that size.Roper® Tuthill® Viking®
