But it can be difficult to know exactly which pump you should choose. There are so many designs and niches that identifying the pump which will meet these three needs can be confusing. To simplify things when trying to select your pump, there are two types of pump which work in very different ways and broadly encapsulate most pump designs.
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.
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.
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.
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.

There are two general types of water pumps: centrifugal pumps and positive displacement design type. Both types follow the same purpose, which is to move water from one point to another continuously. These two major components have a wide variety of options that might be used depending on your project specific needs.
Pump Types and Definitions
Rotary LobeLobe-shaped rotors gently fill with and dispense fluids containing soft particles, solids, and highly viscous fluids. Sanitary construction is perfect for use in the food and beverage industries.
Classification of pumps.
Many kinds of pumps are used in distribution systems. Pumps that lift surface water and move it to a nearby treatment plant are called low-lift pumps. These move large volumes of water at relatively low discharge pressures. Pumps that discharge treated water into arterial…
