Pump & Hydraulic Behaviour Diagrams

1. Pump Curve Shift Due to Fouling

Shows the pump curve moving left as inflow efficiency drops due to screen/gravel-pack blockage.Useful for explaining why pump performance appears “worse” without any mechanical/electrical failure.

2. Increasing Amp Draw with Reduced Inflow

Visualises how restricted inflow forces the pump to operate off the right side of its efficiency range — causing higher amps, motor strain, and intermittent flow.

3. NPSH & Drawdown Effects

Illustrates how reduced inflow increases drawdown, reduces NPSHa, and can risk cavitation in deeper or heavily-fouled bores.
