Maximum Plunger Diameter

DP = 2 × √{FL / (P × π)} Where: DP = Maximum Diameter of Plunger in inchesFL = Rod Load Rating in poundsP = Operating Pressure in pounds per square inchπ = Pi = 3.14159 Maximum Diameter of Plunger [in] = 2 × √{Rod Load [lbs] / (Operating Pressure [PSI] × 3.14159)}...

PD Pump Flow Rate

BHP = Q × P / (1714 × n) Where: BHP = Brake Horsepower in HorsepowerQ = Flow Rate in gallons per minuteP = Pressure in pounds per square inchn = Efficiency expressed as a decimal value* *Many positive displacement pumps are assumed to operate at 90% efficiency. A...
