Frame Size & Head Requirements Estimator — BBP ASJ Deep Well Pump

Frame Size & Head Requirements Estimator
— BBP ASJ Deep Well Pump

Enter your well parameters to estimate total dynamic head and recommended ASJ frame size. BBP engineering provides free exact model selection — this tool gives you an immediate starting point for your specification.

Static Water Level Depth (m)

Distance from ground surface to water surface at rest

Drawdown Allowance (m)

Estimated drop in water level during pumping

Discharge Head / Elevation (m)

Height from wellhead to discharge point

Pipe Friction Loss (m)

Estimated; use 5–15 m for typical 50–150 m rising main

Target Flow Rate (m³/h)

Required flow at the pump discharge

Borehole Casing Diameter (inches)

Pump frame must be ≤80–90% of casing internal diameter

Frame sizes shown above are from BBP ASJ published specification ranges. Total dynamic head = Static level + Drawdown + Discharge head + Friction losses + 10% safety margin. Model selection within a frame size depends on exact stage count and hydraulic curve — BBP engineering provides free model-by-model matching at no charge.
