Watering VS Dewatering Pumps: The Basics

What is a water pump?

Water pumps are mechanical devices used mainly to transfer water from one place to another through a motor converting rotational or kinetic energy into hydrodynamic energy (for fluid flow).

Water pumps usually have three primary parts. These are an inlet, a pump system, and an outlet.

The water gets drawn into the pump from the inlet side when a difference in pressure forms within the pump system. The water is led from an area of high pressure to an area of low pressure, which is then used to move the water to the side of the outlet through the pump, then into a hose, and finally towards the water tank.

What are the uses of a water pump?

Applications of a water pump range from irrigation in agricultural farming systems to water extraction in construction sites. They can also be used in supplying water to residential, commercial, or industrial sites.

What is a dewatering pump?

A dewatering centrifugal pump, just like the name implies, is mainly used to remove water from a particular place and move it to another location.

A dewatering centrifugal pump functions just as any other pump does. It uses an impeller with a blade to begin and continue the movement of the water. The water goes into a smaller part of the impeller called the impeller eye. The flow of the water is then collected from there and directed to the diffuser, which is a conical-shaped discharge nozzle. This is when the velocity of the water is reduced and the energy of the water flow is changed to pressure energy.

After the process described above, the water is then removed from the pump at an angle of 7 to 10 degrees for optimal efficiency. This is the stage of dewatering. To help this process along, mostly an electric motor is used. However, some pumps may use different types of motors.

What are the uses of a dewatering pump?

A dewatering pump finds several applications across various industries including construction, mining, mills, and municipal operations. Any place that needs to be kept dry and clean, such as roads and worksites, will benefit from having a dewatering pump to work smoothly with. During the monsoon season especially, a dewatering pump comes in extremely handy thanks to its effective flood control, groundwater removal, inland wastewater management, and prompt drainage functions.

Types and Specifications of Different Water Pumps

As water pump dealers would tell you, the water pumps are used in construction sites. People use them for dewatering. This is a process whereby extra water that may have accumulated on the site is removed from over there. There are so many reasons why water can build up in these sites. It could be because of heavy rains. At times, the water table could be high as well. The pumps let you move the water within a short period. This helps in reducing the downtime as well. There are two main types of such pumps. 

The types of water pumps

As water pumps distributors would tell you, there are two major variations of water pumps. These are positive displacement pumps and centrifugal pumps. Both these kinds of pumps are designed in such a way that you can move water to another place from where it is continuously. A centrifugal water pump makes use of a rotating impeller so that it can move the water within the pump. This also allows it to force the discharge flow. A positive displacement water pump delivers a specified amount of flow by way of mechanical shrinking and expansion of a diaphragm that is flexible.

Things to keep in mind for centrifugal water pumps

The centrifugal industrial water pumps are used in a wide range of water system and construction applications. They can do a lot more than mere dewatering. They can be used to pump water supplies of buildings. They can also work with pneumatic systems as well as ones where you do not need to use the suction lift. They are also used for pumping water from domestic wells. They can increase pressure in water intake lines as well. They can provide an uninterrupted pressure source used in the fire protection systems too.

Things to keep in mind for positive displacement water pumps 

The positive displacement of Kirloskar water pumps is also referred to as rotary pumps. They are effective. This is because they can remove air from the lines, and this does away with the need to bleed the air as such. They are also extremely handy when it comes to dealing with liquids that have a high amount of viscosity. The main issue with these pumps is that they need a really small clearance between the outer edge of a rotating pump and the pump itself.       

Features and specifications of these pumpsAs you would get to know from your water pump dealers, there are several important factors that you must take into consideration at the time of selecting such a pump. In power, you must look at the horsepower and the flow rate. In the material, you must check if it has been built with weather-resistant materials that are useful when it comes to applications where the pump could be exposed to the natural elements. You also need to check the fuel and the motor type over here, and the total head discharge.
