END-SUCTION CENTRIFUGAL PUMPS
Need help finding the best product for your application
End-Suction Centrifugal Pumps Overview:
An end suction pump is a centrifugal pump with an axial and suction charge at a 90-degree angle to the suction. Many of these pumps have centerline discharge, according to international standards. These end suction pumps can be long-coupled and thus have separate coupling and motor systems. Other ones may have close coupled end suction pumps (where the motor and the coupling are in the same unit), often called a monobloc.
The casing in these end-suction pumps usually creates a volute, which reduces the impeller, shaft, and rotor forces. These pumps can handle different ranges of flow depending on the application, making them a versatile option.
Most end-suction pumps have single-stage pumps, but you can find other options in the market. Many suction pump manufacturers create multi-stage versions that offer controlled flow.

Buyers can find the end-suction pumps in different materials, including bronze, steel, and cast iron. The buyers can choose the material depending on what they wish to do with the end-suction pumps. In addition, the impeller also has multiple versions. Some of these versions may include the following:
- Barske design impeller.
- Disc rotor
- Enclosed radial flow which is the most common)
- Helical screw
- Semi-open
- Vortex
How does it Work?
The end suction pumps have a single volute type casing and an impeller. The pumps work best when the liquid increases velocity after pumping. It moves along the impeller vanes, and diffusion begins in the volute casing, converting the high rate into high pressure.
Most of the end-suction pumps use A.C. electricity for power, but you can find D.C. end-suction pumps. Industries also use other machines for this task, such as hydraulic motors, steam turbines, gasoline engines, and diesel engines.
Buyers can choose between two differently configured end-suction pumps
- Frame-mounted pumps
- Closed coupled end-suction pumps.
The frame mounted pump has its bearing and coupling that separates the two components.
The close-coupled end suction pumps attach directly to the driver shaft without separate coupling. You can use the end-suction pumps in many industrial and residential applications. The standard water pumps, for example, have a normal iron body.
However, heavier industrial applications include a bedplate that separates the motor and the pump. The bedplate can be metal, exotic alloys, or even plastic. The plastic bedplates are best against corrosion and offer maximum performance. You can use the hard-ironed option if you deal with mining, mineral processing, etc.
Applications of End Suction Pumps
End suction pumps are versatile, considering they can produce good pressure levels ideal for industrial and commercial applications. Some common uses for the end-suction pumps include:
- Mining and mineral industry
- Food processing industry
- Chemical and food processing industry
- Clean water and oil services
Bottom Line
End suction pumps are ideal if you are looking for long-term liquid suction options. These pumps have their components at a 90-degree angle, making them suitable for longer, industrial applications.
