Well Pump Capacities in GPM or Water Delivery Rates
Well Pump Capacities in GPM or Water Delivery Rates

The head or pressure that a pump will develop is in direct relation to the impeller diameter, the number of impellers, the eye or inlet opening size, and how much velocity is developed from the speed of the shaft rotation. Capacity is determined by the exit width of the impeller.
