The **Pump Cylinder Stroke Length** calculator computes the stroke length (L) required in a cylinder to displace a volume (V) in a cylinder of a specified diameters (D).

**INSTRUCTIONS**: Choose units and enter the following:

- (
**V**) This is the volume displacement of one stroke of the pump. - (
**D**) This is the diameter of the cylinder of the pump

**Stroke Length (L): ** The calculator returns the length in inches. However this can be automatically converted to compatible units via the pull-down menu.

The formula for the displacement volume of a cylinder in a pump is:

V = π•(D/2)²•L

where:

- V is the volume displaced in one stroke of the pump
- D is the inner diameter of the pump cylinder
- L is the pump cylinder stroke length

This calculator uses the above formula solved for the cylinder stroke length:

L = V/( π•(D/2)² )
