To determine the required horsepower for the Concentric C800 Gear Pump, we can use the following formula: Horsepower=1714×EfficiencyFlow (GPM)×Pressure (PSI)
For the Concentric C800 Gear Pump:
• Flow Rate: 5.4 GPM
• Pressure: 3625 PSI
• Efficiency: Typically around 85% (0.85) for gear pumps
Plugging in these values; Horsepower=1714×0.855.4×3625≈13.1 HP
So, you would need an engine with at least 13.1 horsepower to operate this pump efficiently.
