Difference between centrifugal pump and reciprocating pump

Across the industry, professionals are constantly working to develop and implement the latest in pump and valve technology. Recently, EmpoweringPumps. But for those who need a brush up on pump basics, we thought it would be a good time to discuss the differences between centrifugal and positive displacement pumps. Nearly all pumps fall within these two categories, with centrifugal being the most common. However, positive displacement pumps come in a wider variety such as gear, lobe, peristaltic, screw, and many other types of pumps.

Breadcrumbs You are here: Home Reciprocating Pumps vs. Many times, you may be faced with the decision to use a reciprocating pump or a multi-stage centrifugal pump for a given application. There are some pros and cons for either pump design, depending on:. A centrifugal pump adds kinetic energy to a fluid by means of fast-rotating impellers. There is no fixed volume, and the fluid increases in kinetic energy velocity while moving through impeller passages by centrifugal force resulting from impeller rotation. Its accelerated velocity is converted into pressure head by exiting into the diffuser for discharge, or — in the case of a multi-stage centrifugal pump — it further increases its velocity pressure head by moving through to the next fast-rotating impeller see Figure 1. Centrifugal pumps are usually direct coupled with drivers electric motors or engines without speed reduction.

DIFFERENCE BETWEEN A CENTRIFUGAL PUMP AND A POSITIVE DISPLACEMENT PUMP

There are two main types of pumps available: positive displacement and centrifugal rotodynamic pump. Positive displacement pump: the working principle involves an operation that moves fluid by trapping a fixed volume, usually in a cavity, and then forcing that trapped fluid into the discharge pipe. Centrifugal pump: this involves the transfer of kinetic energy from the motor to the liquid by a spinning impeller. As the impeller rotates it draws in fluid, increasing the velocity which moves the fluid to the discharge point. A centrifugal pump is categorised as a non-positive displacement pump.

My Enquiry List: 0 items View list. Enquiry List. There are two main families of pumps; positive displacement and centrifugal rotodynamic , both of which have their uses and best areas of application. It is important however to be able to identify when each pump type should be selected, which ultimately comes down to their working principle and the application at hand.

 Чед! - рявкнул у него за спиной Фонтейн. Директор наверняка обратил внимание на выражение глаз Мидж, когда она выходила.  - Не выпускай ее из приемной. Бринкерхофф кивнул и двинулся следом за Мидж.

Он открывал секрет, открывал ключ к шифру-убийце - умоляя, чтобы люди его поняли… моля Бога, чтобы его секрет вовремя достиг агентства. - Три, - прошептала она, словно оглушенная. - Три! - раздался крик Дэвида из Испании.

Проклиная себя за то, что не забрала у Стратмора беретту, она пыталась вспомнить, где осталось оружие - у него или же в Третьем узле. Когда глаза Сьюзан немного привыкли к темноте, она посмотрела на дыру, зияющую в стеклянной стене.
