Positive displacement pumps vs centrifugal pumps

Positive displacement pumps and centrifugal pumps are two different types of pumps that are commonly used in various industries for pumping liquids.

Positive displacement pumps use mechanical force to move fluid, which is done by trapping a fixed amount of liquid and then forcing it through a discharge port. This type of pump is ideal for pumping thick, viscous liquids or liquids with suspended solids.

On the other hand, centrifugal pumps use a spinning impeller to create a low-pressure area that draws in fluid, which is then forced out of the pump under pressure. This type of pump is more suited for thin, low-viscosity liquids.

Overall, the main difference between positive displacement pumps and centrifugal pumps is in the way they move fluid. Positive displacement pumps use mechanical force to move fluid, while centrifugal pumps rely on the centrifugal force created by a spinning impeller.

Types of positive displacements pumps

Positive displacement pumps are a type of pump that moves fluid by trapping a fixed amount of liquid and then forcing it through a discharge port. They are ideal for pumping thick, viscous liquids or liquids with suspended solids, and are used in a wide range of industries, including food and beverage, oil and gas, and pharmaceuticals.

There are several types of positive displacement pumps, each with its own unique advantages and disadvantages. Here are some of the most common types of positive displacement pumps:

  1. Rotary pumps: These pumps use a rotating mechanism, such as gears or lobes, to move fluid. Rotary pumps are simple and reliable, and can handle a wide range of viscosities.

  2. Reciprocating pumps: These pumps use a piston or diaphragm to move fluid. Reciprocating pumps are ideal for pumping high-pressure or high-viscosity fluids.

  3. Peristaltic pumps: These pumps use a flexible tube or hose that is squeezed by rollers or shoes to move fluid. Peristaltic pumps are ideal for pumping delicate or shear-sensitive fluids, as they do not apply any mechanical shear to the fluid.

  4. Screw pumps: These pumps use a helical screw to move fluid. Screw pumps are ideal for pumping thick, viscous fluids and can handle solids and abrasive particles.

  5. Progressive cavity pumps: These pumps use a rotating screw-like rotor inside a stator to move fluid. Progressive cavity pumps are ideal for pumping highly viscous or abrasive fluids.

In summary, positive displacement pumps are an important tool for pumping viscous and solid-laden liquids in various industries. Understanding the different types of positive displacement pumps can help you choose the right pump for your specific application.
