Self Priming Pump - Perfect for the air and water mixture pumping

About Self Priming Pumps

Self priming pump is widely used for pumping water or any liquid material from one level to another. For moving water from source to destination, air and water both get combined to meet a completely ready pumping status. These types of pumps are more preferable for the industrial purposes depending on their quality and features.

Few pumps get fail to work when even a small amount of air get combined in the pump chamber. That time, you have to stop your work and have to remove the air for the smooth pumping process. But self priming pump overcome this drawback. They work very efficiently and without any hassle even if a pump gets a mixture of air and water. These pumps are specifically designed to get rid of this problem. It works in the same way as the water alone flows in the ordinary pumps. You will get no idea that your pump has air inside as it will not stop for a single minute due to the air presence. Self priming pump automatically removes every single particle of air and when it gets completed you will ultimately pump the water only. It has the power to deal with the air present in the pump but do not turn on the pump if there is no water.

Self Priming Pump Functioning

You must know how it actually works and give beneficial advantages to the various industrial applications.

Self priming pump starts operating when an air is mixed with water by flowing through the impeller. When the sufficient amount of air gets completely dissolved with the water, then this mixture is moved to the water reservoir by using the highly powerful centrifugal force. The process works in a very interesting way. The air get back to the impeller with the help of this force as it can easily be raised upwards because of the heavier weight of water than the mixture of air and water. With this effect, the air goes back to the impeller and goes removed from the mixture. But still few air particles are left in the mixture. The process of raising and moving the air to the impeller continues until every particle will not get removed from the mixture. When a single particle is dispelled out of the chamber, the air-free water moves to the suction line and then goes to the impeller. A self priming Centrifugal Pump will help to pull the water using the pressure energy.

A special water tank is used in the self priming pumps in order to carry the process of air removal from the mixture of air and water using the priming cycle. These pumps do not require any kind of ejector or vacuum pumps like used in other types of ordinary pumps.

Applications Of Self Priming Pumps

These pumps are used in several applications to ease the water or any liquid pumping process. They are used in petrochemical, mining, automotive and various other industries where heavy volume of liquids, water and chemicals has to pump out by mechanical action. The pumps do not generate any pressure, they are used just to flow the liquid from one level to another or from one location to another.

Use self priming pump to handle large volume of water or other heavy liquids with great ease without any vacuum or ejector pumps.

Centrifugal Pump: Ordinary machine with extraordinary features

Since ancient age, humans have been trying to discover a convenient way to lift water to higher levels for household, irrigation and many other purposes. It is believed that the thought of water lifting by centrifugal force was first sparked at the end of 16th century. As years progressed, a continuous advancement in these pumps has lead us to a highly advanced form of this machine which is used in wide array of applications of our daily life, across the world.

One of the leading suppliers of pumps and related equipment and parts, Rotech Pumps & Systems Inc. offers extensive range of reliable products at competitive pricing and minimum lead time to Industrial, commercial and municipal sectors.

Introduction

Typically, a pump can be defined as a device that lifts water or other fluids from lower to higher level when driven by an external source. Technically, a pump may also be defined as a machine that converts mechanical energy to pressure energy. And the pump which employs centrifugal force to raise water from lower level to higher is known as a centrifugal pump. A centrifugal pump is Roto dynamic in nature and uses a rotating impeller similar to that of a turbine to increase liquid pressure. The impeller is enclosed in a watertight casing and curved vanes are fitted to this impeller. The impeller also has a delivery pipe on one of its sides. The design of the pump's casing converts kinetic energy of the water into pressure energy before water leaves the casing. This in turn considerably increases the efficiency of the pump.

Working

Centrifugal pumps operate by converting the moving force of kinetic energy, which is resultant of electric motor or turbine, to a static liquid pressure. Principle of Bernoulli describes this process well. Once the pump impeller begins to rotate, it imparts kinetic energy to the fluid which is drawn inside the pump from the impeller eye. The fluid is then forced outward to the periphery because of centrifugal force. As the fluid exits the impeller, its kinetic energy is transformed into static pressure as the fluid experiences change in the area in the volute section. The primary reason for the conversion of energy is the volute shape of the pump casing or the vanes. Essentially, the function of the diffuse is to decelerate the fluid and convert kinetic energy into flow work which then results in the increase in the pressure on the downstream side. The entire process causes liquid to flow. The total energy usage of a centrifugal pump for the entire pumping process can be estimated quite easily based on the required flow, the height lifted and length of the pipeline.

Applications

The most common applications of a centrifugal pump include Petrochemical Pumping, Petroleum, water supply and sewage amongst others. A water turbine is the reverse function of the centrifugal pump where in potential energy of water pressure is converted into mechanical rotational energy.

Disadvantages

In spite of the extensive application in household and diverse industrial sectors, centrifugal pumps have some problem with regard to erosion, corrosion, leakage, overheating etc. Hence, they require regular maintenance.

Multistage Centrifugal Pumps

A multistage centrifugal pump is a type of centrifugal pump with two or more impellers. These impellers maybe mounted on the same shaft or different. The impellers can be connected in series at the outlet if higher pressure is required. However, in cases where higher flow is required, impellers can be connected in parallel. A common usage of a multistage centrifugal pump is in the boiler feed-water pump. 

Get Brief Introduction about Centrifugal Pumps and their Uses

Centrifugal Pump & Its Working

Centrifugal pump is a machine that helps in lifting water or any other liquid from lower level to higher level. Such types of pumps are used for a variety of applications such as waterfalls, fountains, sprinkling etc. These days everyone wants to follow most convenient ways for water supply for various irrigation purposes. The high perfection of centrifugal pumps has made it popular all over the world and is widely used for various purposes.

In other words, we can also say that these pumps are the source of raising water to higher level with the combination of mechanical energy and pressure energy. It works exactly as the reserved reaction turbine. In this, the water at high pressure enters the casing; as a result that gives high level of mechanical energy to the shafts. This water then enters to the impeller and generates pressure energy to get water flows outside the machine. The main function of impeller is to turn the driver energy into kinetic energy by revolving during the machine working. Both impeller and volute work together to get high flow of water with the pressure generated inside the machine.

Usage Of Centrifugal Pumps

Centrifugal pumps are used in different industries and can also be used at home for daily work. If you want to store a huge quantity of water in your water storage area, then you can use these pumps to lift water from the ground level to the upper level. These pumps use centrifugal force to lift and move the water or any liquid though piping systems.

You can find different types of centrifugal pumps available in the market. Whether you are going to purchase these pumps for household or agricultural use, a standard pump works efficiently to accomplish your required tasks. Such type of pumps has limited capabilities and cannot be used for high pressure activities. No doubt they have become an economical choice for several users, but make them able to use for low pressure water flow activities only. For fire control, high pressure washing machinery, irrigation etc., high pressure centrifugal pumps are used with higher capacity.

Choose Your Centrifugal Pumps Carefully

You need to be little careful when going to select the pump to accomplish your needs. You need to consider the amount of pressure required for the application and consider the material being pumped. These pumps can be used for pumping oil, fertilizer and any other chemical. For chemical processes and DE-ionization of water, closed coupled pumps are used.

Before, making any final decision, make sure to check the liquid discharge pressure and volume of the selected pump. These pumps are well known for excellent water lifting machine and also do not involve high maintenance. We can say that buying centrifugal pumps not only make your water lifting activities easier, but also save large of money.

A comprehensive comparison between API and ANSI chemical pumps

Rotech Pumps & Systems Inc. is one of the leading suppliers of pumps and related equipment and parts. Since a decade, Rotech Pumps has been providing best quality products at competitive pricing and minimum lead time to Industrial, commercial and municipal sectors. One of the primary products of Rotech Pumps is ANSI Chemical process pumps. They are designed to handle corrosive fluid and used for heavy duty applications.

Chemicals are primary component of numerous industries and to handle and transfer large quantity of chemicals in efficient manner, a chemical process pump has become an inevitable tool for these industries. API and ANSI pumps are two of the most commonly used horizontal end suction chemical process pumps.

An ANSI pump is designed and manufactured as per the standards of the American National Standards Institute. It is the preferred choice not only for chemical process applications but also for water and other less aggressive applications. This is because ANSI centrifugal pumps provide flexibility of interchangeability of pumps from one manufacturer to another.

API pumps are built to meet the requirements of the American Petroleum Institute Standard and almost exclusively employed in oil refinery industry to handle higher temperatures and pressure application. However, both these single staged pumps are designed with a radially split casing to accommodate a back pullout arrangement for easy maintenance.

Major differences between API and ANSI Pumps:

• Volute Case: ANSI pumps and smaller sized API pumps possess a single volute design of passage. Due to this design of volute an imbalance of the thrust loads around the impeller. However, larger API pumps employ double volute design to reduce these loads.

• Back cover arrangement: The back cover and gasket in ANSI centrifugal pumps are supported against the pump casing by the bearing frame adaptor. Due to this arrangement when the pressure applied increases than the normal, the casing may get fractured. But on the other hand, in API pumps, the back cover is directly bolted to the casing and the adaptor doesn’t play a part in the pressure boundary.

• Mounting Feet: ANSI pump casing are mounted on feet projecting from the underside of the casing. Because of this design, when ANSI pumps are used in high-temperature applications their casing expands upward and causes thermal stress which will in turn have detrimental effect on the reliability of the pump. In contrast, API pumps are mounted at the horizontal centerline of the casing on feet projecting from each side of the casing. This ensures that API pumps can function at higher temperatures and thus gives them slight advantage over ANSI Pumps.
