Options:

• Clockwise Rotation when looking at pump shaft (Counterclockwise available as an option)
• Keyed shaft 5/8" diameter (3/4" keyed and 9 tooth spline shaft available as an option)
• Side Port (Rear port optional)

Helpful calculations:

Pump flow in gpm = cc/rev. x rpm ÷ 3785 [example: 20cc/rev x 1800rpm ÷ 3785 = 9.5gpm]

Power to drive pump in HP = gpm x psi ÷ 1714 ÷ .85 [example: 9.5 gpm x 3000psi ÷ 1714 ÷ .85 = 19.6HP]

Terms:

cc/rev = displacement per revolution of pump (provided with the pump data)

rpm = revolution per minute the shaft is being rotated (based on users driving source)

gpm = output flow of pump in gallons per minute

3785 = constant value to convert cc/rev. to gpm

1714 = constant value to convert flow and pressure to HP

.85 = common efficiency value to account for mechanical and volumetric losses
