Pump Curve Calculator
Calculate pump performance curves, analyze efficiency, and determine operating points for centrifugal pumps. Essential tool for engineers and technicians in fluid systems design.
Step 1: Pump Specifications
Understanding Pump Curves
Pump curves show the relationship between flow rate and head pressure. The Best Efficiency Point (BEP) is where the pump operates most efficiently with minimal wear.
Step 2: Fluid & System Properties
About System Curves
System curves represent the resistance of the piping system. The operating point is where the pump curve intersects the system curve. Proper selection ensures optimal pump performance.

Pump Curve Analysis
Power Calculation Formula
P = (ρ × g × Q × H) / (η × 1000)
Where: ρ = fluid density (kg/m³), g = gravity (9.81 m/s²), Q = flow rate (m³/s), H = head (m), η = pump efficiency (decimal). This gives hydraulic power in kW. Shaft power includes mechanical losses.
