Each type of pump has its own strengths and weaknesses. As a buyer, you will often find it difficult to choose among the multiple pump types that can be selected for the same application. In this blog, almost all of your questions regarding end suction pumps will be answered.
An end suction pump is the most basic type of centrifugal pump typically designed with a casing. The suction is present on one end and the discharge is placed at the top. Hence, the name end-suction pump is given.
End suction centrifugal pumps normally contain an impeller and a casing which has coil windings. When the pumped liquid passes through the blades and fins of the impeller, its velocity increases. This liquid then passes through the volute casing. Here its high velocity is converted to into high pressure through a process of diffusion.
End suction pumps can be driven by any of these:
1. A.C. electric motor
2. D.C. motor
3. hydraulic motors
4. air motors
5. petrol and diesel engines
6. steam turbines
End suction pumps may be close-coupled or frame-mounted. These pumps are the best choice for intermittent and non-critical service applications.
