Specific speed is used for many design purposes including efficiency prediction and classifying the relative discharge of an impeller as radial, mixed or axial and expressed by the following equation: Specific Speed Equation. This type is commonly referred to as a centrifugal pump. In In centrifugal pumps the liquid enters the impeller at the hub and flows radially to the periphery, exiting perpendicular to the rotating shaft.
Hello readers, in this article we will talk about the pump and its types. And at the end of the article, I will give you a PDF downloadable link. A pump is a device that is used for lifting the liquid from ground sources to the upper top surface or from one place to another place. Pumps are operated by the mechanism that is rotary, reciprocating and it consumes energy while performing mechanical work which is moving fluid from one place to another. This can be operated by many energy resources which include manual operation, electricity, engine, wind power and many more, day to day life to industrial applications.
In this article, you will learn about the Reciprocating pump, its Definition, Main Parts, Types, working principle, and the difference between the reciprocating and centrifugal pump. In this pump, a piston is reciprocating, which uses thrust on the liquid and increases its hydraulic energy. Because it discharges a definite quantity of liquid. It is often used where a small quantity of liquid is to handled and where delivery pressure is quite large. Read also: What is Centrifugal Pump? A cylinder, in which piston is moving to and fro.
A pump is a device that moves fluids liquids or gases , or sometimes slurries , by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift , displacement , and gravity pumps. Pumps operate by some mechanism typically reciprocating or rotary , and consume energy to perform mechanical work moving the fluid. Pumps operate via many energy sources, including manual operation, electricity , engines , or wind power , and come in many sizes, from microscopic for use in medical applications, to large industrial pumps. Mechanical pumps serve in a wide range of applications such as pumping water from wells , aquarium filtering , pond filtering and aeration , in the car industry for water-cooling and fuel injection , in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry , pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis.

Welcome to a World of Pumps For more than 75 years Johnson Pump brand Johnson Pump brand models pumps have been developed, manufactured Centrifugal pumps Positive displacement pumps and marketed for industrial use.
There are different types of pumps available in the market. This article will assist you to know the main functionalities of each type of pump. The type of pump, as well as selection, mainly depend on our requirement.
Head, performance curve and affinity laws all contribute to the efficiency of centrifugal pumps. Pumps are generally grouped into two broad categories—positive displacement pumps and dynamic centrifugal pumps. Positive displacement pumps use a mechanical means to vary the size of or move the fluid chamber to cause the fluid to flow. On the other hand, centrifugal pumps impart momentum to the fluid by rotating impellers that are immersed in the fluid. The momentum produces an increase in pressure or flow at the pump outlet. Positive displacement pumps have a constant torque characteristic, whereas centrifugal pumps demonstrate variable torque characteristics. This article will discuss only centrifugal pumps.

Я жду. Бринкерхофф застонал, сожалея, что попросил ее проверить отчет шифровалки. Он опустил глаза и посмотрел на ее протянутую руку. - Речь идет о засекреченной информации, хранящейся в личном помещении директора.
Поэтому я хочу узнать мнение специалиста. - Что ж, - сказал Джабба, - мне неприятно первым тебя разочаровать, но твои данные неверны. - Ты так думаешь. - Могу биться об заклад.
Коммандер, - сказал Чатрукьян, - я уверен, что нам надо проверить… - Подождите минутку, - сказал Стратмор в трубку, извинившись перед собеседником.
Нет, Мидж. Это абсолютно исключено. - Спасибо.
Директор нахмурился и повернулся к экрану. - Мистер Беккер, я был не прав. Читайте медленно и очень внимательно. Беккер кивнул и поднес кольцо ближе к глазам. Затем начал читать надпись вслух: - Q… U… 1…S… пробел… С, Джабба и Сьюзан в один голос воскликнули: - Пробел? - Джабба перестал печатать.
- Если не скажешь, тебе меня больше не видать. - Врешь. Она ударила его подушкой.
