A Giant P219R pump has a power requirement of 5.8 HP (4.3 kW).
It's designed for a maximum flow of 4.2 GPM and a maximum discharge pressure of 2000 PSI, at a crankshaft speed of 1750 RPM.
However, under intermittent use, the maximum power consumption can reach 7.2 HP (5.4 kW), with an intermittent discharge pressure of 2500 PSI.
Therefore, when selecting a motor to drive a Giant P219R pump, it's recommended to choose a motor with a minimum of 5.8 HP, and ideally closer to 7.2 HP to account for potential intermittent demand or a service factor of 1.15 if choosing an electric motor, according to Giant Pumps
