Fixed Displacement Pump Symbol

What is a Fixed Displacement Pump?

Fixed displacement pumps represent a category of hydraulic equipment that produces a predetermined fluid volume during each complete rotation of the drive shaft. The volumetric output remains consistent provided the rotational speed stays unchanged. These pumps are characterised by their straightforward construction and versatility across numerous industrial applications.

How does a Fixed Displacement Pump Work?

Hydraulic pumps with fixed displacement, including gear and vane designs, capture a predetermined quantity of fluid within chambers formed by rotating components such as gears, vanes, or pistons. The captured fluid is then transported to the discharge opening through mechanical action. Each complete shaft rotation repeats this cycle, producing a steady volumetric output.

What is the Symbol for Fixed Displacement Pump?

The fixed displacement hydraulic pump symbol is a graphical representation of the device, used to provide engineers with a faster and easier means of determining its location within a system without needing a physical inspection.

It is usually portrayed as a circle with an arrow inside of it, pointing in the direction of the flow.
