Pump Selection Calculator
Calculate the optimal pump specifications for your application. Determine pump type, power, flow rate, head requirements, and efficiency based on your system parameters.
Step 1: System Requirements
Understanding Pump Head
Total Dynamic Head (TDH) is the total equivalent height that a fluid is to be pumped, taking into account friction losses in the pipe. It includes static head, friction head, and pressure head.
Step 2: Pump & Efficiency
About Pump Efficiency
Pump efficiency is the ratio of hydraulic power delivered to the fluid to the mechanical power input at the pump shaft. Higher efficiency pumps consume less energy for the same output, reducing operating costs.

Power Consumption Breakdown
Pump Power Formula
Power (kW) = (Flow × Head × Specific Gravity) / (367 × Pump Efficiency)
To calculate pump power requirement: Multiply flow rate (m³/h) by head (m) and fluid specific gravity, then divide by 367 times pump efficiency percentage. For imperial units: Power (HP) = (Flow × Head × Specific Gravity) / (3960 × Pump Efficiency).
