Pump Flow Calculator
Calculate pump flow rate, efficiency, and performance. Determine flow rates based on pump specifications, speed, head, and system requirements for optimal performance.
Step 1: Pump Specifications
Understanding Pump Efficiency
Volumetric efficiency typically ranges from 80-95% for most pumps. Higher efficiency means less energy loss and more effective fluid transfer.
Step 2: System Requirements
About Pump Performance
Total head includes static head, friction losses, and pressure requirements. Specific gravity affects hydraulic horsepower requirements.

Pump Flow Formula
Flow Rate (GPM) = (Speed × Displacement × Efficiency) / 231
To calculate flow rate: Multiply pump speed (RPM) by displacement (in³/rev) and volumetric efficiency, then divide by 231 (cubic inches per gallon).
