  • Characteristics of Centrifugal Pumps - pumpsandsystems

    24/10/2019  Positive displacement pumps have a constant torque characteristic, whereas centrifugal pumps demonstrate variable torque characteristics. This article will discuss only centrifugal pumps. A centrifugal pump converts driver energy to kinetic energy in a liquid by accelerating the fluid to the outer rim of an impeller.

  • Centrifugal pump - Wikipedia

    Centrifugal pumps for solids control. An oilfield solids control system needs many centrifugal pumps to sit on or in mud tanks. The types of centrifugal pumps used are sand pumps, submersible slurry pumps, shear pumps, and charging pumps. They are defined for their different functions, but their working principle is the same.

  • How To Read A Centrifugal Pump Curve - Crane Engineering

    26/6/2014  In this post, we'll break down the anatomy of a centrifugal pump curve. A centrifugal pump imparts energy on a liquid, and based on the system it is installed on, has flow and head characteristics. The amount of pressure the pump is required to overcome dictates where the performance point will be on the curve and how much flow is produced.

  • What is a Centrifugal Pump Intro to Pumps

    A centrifugal pump is a machine that uses rotation to impart velocity to a liquid, it then converts that velocity into flow. Centrifugal pumps are made up of two primary components: an impeller and a casing. The rotating impeller generates velocity and the casing converts velocity into flow.

  • Centrifugal Pump KSB

    Centrifugal pump principle in brief. Invented in the 17th century, the basic principle is still used today. Inside a centrifugal pump, an impeller rotates on a drive shaft. The impeller accelerates the flow of the fluid handled. The centrifugal force moves the fluid towards the outer edge of the pump impeller.
