What are Positive Displacement Pumps and How Do They Work?

A positive displacement pump decreases the volume containing the liquid until the resulting liquid pressure equals the pressure in the discharge system.

While these pumps can move various types of fluids, they are generally used for viscous liquids and fluids that contain suspended or fragile solids.

These pumps essentially trap a portion of the fluid between threads or cavities and move the fluid to the pump outlet without excessive shearing action.

The DAE Pumps piston pumps use high-quality O-rings to ensure reliable performance.

Positive Displacement Metering pumps are usually used where a high degree of accuracy is required e.

    Positive Displacement Pump. Pumps that discharge volumes of liquid separated by periods of no discharge. The purpose of positive displacement pumps is for metering, which provides high accuracy. With a positive displacement pump, a certain volume of liquid is discharged due to the thrust exerted on it by a moving member for each cycle of pump operation.

    Positive displacement pumps are typically used to pump high viscosity fluids such as oils, paints, resins or foods. They are preferred in any application where precise metering or high pressure output is required. Unlike centrifugal pumps, the output of positive displacement pumps is not affected by pressure, so they are also often preferred in any situation where supply is irregular. Most are self-priming.

    A positive displacement (PD) pump is used to move a liquid frequently with a set volume, with the help of valves otherwise seals by moving it automatically throughout the system. The action of pumping is repeated & can be driven by screws, pistons, lobes, gears, vanes, diaphragms.

    Positive-displacement pumps represent a small but significant portion of the world of pumps which also includes dynamic-displacement—mainly centrifugal—pumps, which are by far the larger slice. Although positive-displacement pumps were once the mainstay for pumping fluids of any kind, centrifugal pumps have taken on much of the low-pressure, high-volume work, leaving positive-displacement machines to handle more specialized pumping tasks.

    Positive displacement pumps are often used to pump high viscosity fluids, like oil, paint, resin or foodstuffs. They are favored over centrifugal pumps in any application where accurate dosing or higher viscosity/higher percent solids material needs to be handled. The output of a positive displacement pump is marginally affected by changes in pressure.
