Difference between Centrifugal Pump and Reciprocating Pump

Brief Introduction

Trity Enviro Solutions always makes sure that its customer gets the best of the equipment and the infrastructure when it comes to the wastewater treatment system. That’s why it’s our experts who are working day and night in order to smoothen the process. Although there are many companies in the market that are providing services like us but what we want our customers to know about us is that we offer complete solutions related to water treatment and it is our motto to provide our customers with the best of the technology so that they can get clean and clear water for their required purpose.

Water Treatment plants are nothing but simple plants that help in the treatment of wastewater coming from different sources and contain some hazardous substances that might cause loss to the environment and the aquatic life because the wastewater gets discharged directly into the water bodies without any treatment. Therefore, it is necessary to install plants like sewage treatment plants, effluent treatment plants, and many other plants as per the requirement so that greater harm can be prevented and dependency on freshwater sources can be lowered.

Centrifugal Pump and Reciprocating Pump

Today, we are here to talk about two important components when it comes to water treatment plants and those are the centrifugal pump and reciprocating pump which are integral to the wastewater treatment plant therefore it is a must for us to know about them so that things can become easy for us. So, let's begin with the centrifugal pump which can be easily purchased through a centrifugal pump manufacturer and it helps in the moving of fluids with the help of rotational energy. If we talk about the various components of the centrifugal pump then those are the impeller, casing and inlet and outlet for the fluid flow. You can easily find the usage of this pump in various industries and applications that include water supply systems, chemical processing plants and oil refineries, etc.

Now, The second one is the reciprocating pump is another type of positive displacement pump that uses reciprocating motion to transfer fluids. Now, if we talk about the working of a reciprocating pump then we need to understand that, unlike the centrifugal pump, a reciprocating relies on one or more pistons or plungers to create pressure and move the liquid.  The pump contains various parts like a cylinder, piston or plunger, suction, discharge valve, inlet, and outlet for fluid flow, and the use of this pump can be found in the oil and gas industry, chemical processing plants, power generation plants, and many more.

Difference Between Centrifugal and Reciprocating Pump

After going through the basics of both these pumps, now is the time when we are required to understand the basic difference between both these pumps that can be easily bought from a water treatment plant manufacturer so that we can understand the basics behind these two pumps. So, below are some of the key differences that are worth considering when it comes to exploring centrifugal and reciprocating pumps.

  • Principle of Operation- The first difference that comes in is based on the principle of operation because here the centrifugal pump works on the principle of centrifugal force by rotating the impeller to create the centrifugal force whereas the reciprocating pump works on the reciprocating motion of one or more pistons or plungers by using back and forth motion to create positive displacement.
  • Fluid Transfer- When it comes to transferring the fluid then the centrifugal pump is best for transferring liquid from lower to moderate pressures but at the same time when it comes to transferring the liquid at high pressure the reciprocating pump is the best to go for it.
  • Pressure Generation- The fluid in use helps in the formation of kinetic energy in a centrifugal pump that ultimately helps in generating higher flow rate to lower pressures but the reciprocating pump creates pressure by displacing a fixed volume of fluid with each stroke. They provide a consistent flow rate irrespective of the system pressure.
  • Flow characteristics- Another important thing to take into notice about the centrifugal pump is its ability to provide a continuous and smooth flow of liquid without any pulsation. On the other hand, a reciprocating pump gives a pulsating flow due to the intermittent displacement of fluid.


So, we can conclude by observing the earlier discussed factors that there are various factors that need to be understood in detail so that the correct selection of equipment can be chosen and the desired result can be achieved easily. And if you ever feel that you are facing difficulty in choosing between these or for anything then you can simply contact our excerpts who will help you in selecting the right product as per your need.
