How to select a centrifugal pump: the first in a series of articles on the principles of pump operation.(back to basics)Frankel, Mike
The impeller is always submerged in water, and when the pump is operational the impeller spins rapidly. The centrifugal force applied to the water from this rotation forces the water outside of the casing, where it exits a discharge port. More liquid is introduced through a suction port, or...
Head, Impeller Trim Diameter, Efficiency, Power, NPSHR, MCSF (Minimum Continuous Stable Flow) and RPM. The Pump curve also displays the Pump model, the Pump size and number of stages for multi-stage pumps.
A self-priming design eliminates the need for troublesome internal check valves or external foot valves to maintain prime.These design features give a mag drive centrifugal pump significant advantages over other pump styles. As you select a pump for your application, consider these 5 Benefits of ...

(57) the combination of the vacuum pump and centrifugal pump, [summary] The present invention relates to a method and to control the functions of the gas separation centrifugal pump. Device according to the invention is characterized in that it is controlled by members of the gas flow in the...
The typical home sump pump uses a centrifugal pump to move water. When the motor is on, it causes a screw- or fanlike device called an impeller to turn. Using centrifugal force, the spinning impeller forces water toward the sides of the pipe, creating a low-pressure area at its center....
This pump curve explanation also discusses variables such as: RPM Impeller size, as they related to pump performance Power Efficiency Net Positive Suction Head (NPSH) in centrifugal and positive displacement pumps For example, if you know the flow rate your application requires, you find the gallon...
