Pump types and applications


Incorporates dimensional standardization, which allows for the piping, foundation, and design to be completed before pump suppliers are even selected. Also features more material options than other types.

Pump types and applications


Centrifugal Pumps are useful since they can generally handle large quantity of fluids, provide very high flow rates (which may vary with the changes in the Total Dynamic Head (TDH) of the particular piping system) and have the ability to adjust their flow rates over a wide range.

Selecting between Centrifugal Pumps and Positive Displacement Pumps

Liquids with high viscosity fills the clearances of Positive Displacement Pumps causing higher volumetric efficiencies and Positive Displacement Pumps are better suited for higher viscosity applications. A Centrifugal Pump becomes very inefficient at even modest viscosity.

Pump types and applications

Centrifugal pumps are categorized by several factors, including the type and number of impellers, suction, and the output they produce. Thus, it is essential to know the basics to compare types and applications for the best results.

Choose the Right Types of Pumps for Your Application

In the world of the majority ("small" pumps), a few simple but common-sense features make the difference in longevity: short stubby shafts (L3-D4 ratio), packing as a default choice (mechanical seals only if absolutely necessary, such as when handling tough chemicals with no leaks allowed), no axial adjustments, and simplicity and robustness. These features will make pumps run well for a long time with little waste.

Centrifugal pumps are used often in industrial applications. These pumps use a rotating impeller to accelerate a fluid and increase its pressure. There are dozens of industrial centrifugal pumps including slurry pumps, chopper pumps, sewage pumps, vertical turbine pumps, axial flow pumps and more.

A centrifugal pump is a machine that uses rotation to impart velocity to a liquid, and converts that velocity into flow. In other words, a centrifugal pump uses an impeller to move fluids. Most centrifugal pumps consist of an impeller, the casing, and a motor as the main components. The impeller is the piece that is submerged in water and spins in a circular motion, which receives the rotational energy from the motor.

Positive displacement pumps are efficient in situations requiring low vacuums. There are many common positive displacement pumps, but there are two that are used for most industrial applications: the diaphragm pump and the rotary vane pump.
