DIFFERENCE BETWEEN A CENTRIFUGAL PUMP AND A 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. Positive displacement pumps are characterised by an operation that moves fluid by trapping a fixed volume, usually in a cavity, and then forces that trapped fluid into the discharge pipe. For visual reference of the performance comparisons between the two working principles see below performance curves that show how both centrifugal and positive displacement pumps' duty are affected by different factors. Centrifugal pumps are the most common pump type for the transfer of low viscosity fluids in high flow rate, low pressure installations, which makes them ideal for applications that require the pump to deal with large volumes.

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.

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.

The Differences Between Centrifugal Pumps Vs. Positive Displacement Pumps

Сьюзан стукнула кулаком по столу: - Нам необходимо это кольцо. Ведь на нем - единственный экземпляр ключа! - Теперь она понимала, что нет никакой Северной Дакоты, как нет и копии ключа. Даже если АНБ расскажет о ТРАНСТЕКСТЕ, Танкадо им уже ничем не поможет.

Ему в голову пришла другая мысль.  - Вы дежурили все это время. - Моя смена от семи до семи, - кивнула женщина. - Тогда вы наверняка ее видели. Это совсем молоденькая девушка.

 - Сегодня не его дежурство. - Похоже, что-то стряслось, - сказала Сьюзан.  - Наверное, увидел включенный монитор. - Черт возьми! - выругался коммандер.  - Вчера вечером я специально позвонил дежурному лаборатории систем безопасности и попросил его сегодня не выходить на работу.

Беккер перешел чуть ли не на шепот: - Я здесь, чтобы узнать, не нужно ли вам чего-нибудь.  - Скажем, принести пару таблеток валиума. Наконец канадец опомнился. - Из консульства? - Его тон заметно смягчился. Беккер кивнул. - Так, значит, вы не по поводу моей колонки. - Нет, сэр.

Завтра они скажут мне спасибо, - подумал он, так и не решив, правильно ли поступает. Набрав полные легкие воздуха, Чатрукьян открыл металлический шкафчик старшего сотрудника лаборатории систем безопасности. На полке с компьютерными деталями, спрятанными за накопителем носителей информации, лежала кружка выпускника Стэнфордского университета и тестер. Не коснувшись краев, он вытащил из нее ключ Медеко. - Поразительно, - пробурчал он, - что сотрудникам лаборатории систем безопасности ничего об этом не известно.

У него закружилась голова. Увидев выгравированные знаки, Беккер страшно удивился. Он совсем забыл про кольцо на пальце, забыл, для чего приехал в Севилью.

Probably bcoz centrifugal pumps are continuous while reciprtocating pumps are discontinuous process.

The main difference between reciprocating and centrifugal pump is, In a reciprocating pump, the discharge is fluctuating and pulsating whereas the discharge is smooth and continuous in the centrifugal pump.
