Pump Power Calculator — Calculate Hydraulic Power & Energy Consumption

Pump Power Calculator

Calculate pump power requirements, hydraulic power, and energy consumption for various pump types. Understand how flow rate, head, and efficiency affect pump performance.

Step 1: Pump Parameters

Understanding Pump Parameters

Flow rate is the volume of liquid pumped per unit time. Total head is the total equivalent height that the fluid is pumped against gravity, including friction losses.

Step 2: Efficiency & Operating Conditions

About Pump Efficiency

Pump efficiency accounts for hydraulic, mechanical, and volumetric losses. Modern pumps typically range from 60-85% efficiency. Motor efficiency varies by type and size, typically 85-95% for electric motors.

Pump Power Formula

Hydraulic Power (kW) = (Q × H × ρ × g) ÷ (3.6 × 10⁶)

Where: Q = Flow rate (m³/h), H = Total head (m), ρ = Density (kg/m³), g = Gravity (9.81 m/s²).
Motor Power = Hydraulic Power ÷ (Pump Efficiency × Motor Efficiency)
