Gear Pump Size Calculator

Gear Pump Size Calculator

Calculate the pump displacement per revolution using: $$ V_{rev} = \frac{60\,Q}{\text{RPM}} $$ and convert to mL/rev: $$ V_{rev}\ (\text{mL/rev}) = \frac{60\,Q}{\text{RPM}} \times 10^6 $$

* Enter the desired volumetric flow rate \( Q \) (in m³/s) and the pump speed (RPM).

Step 1: Enter Parameters

e.g., 0.01 m³/s

e.g., 1500 RPM

Formula: $$ V_{rev} = \frac{60\,Q}{\text{RPM}} \times 10^6 $$
(Result in mL/rev)
