Application guide for vertical submerged centrifugal pump

Application guide for vertical submerged centrifugal pump


There are many different types of centrifugal pumps, each with their own specific set of applications. In this guide, we will focus on the vertical submerged centrifugal pump, which is often used in wastewater treatment plants.



The first step is to select the right pump for the application. There are many different factors to consider, such as the flow rate, head loss, and NPSHA.


Once the proper pump is selected, it must be installed in the correct position. The inlet and outlet must be aligned correctly, and the pump must be level.


The next step is to commission the pump. This involves priming the pump and then starting it up. Once the pump is running, it must be monitored closely to ensure that it is operating correctly.


If you follow these steps, you will be well on your way to successful operation of your vertical submerged centrifugal pump!

How to maintain vertical submerged centrifugal pump


Proper maintenance of a centrifugal pump includes regularly checking the pump for signs of wear or damage, as well as keeping the pump clean and free of debris. Additionally, it is important to make sure that the pump is properly lubricated and that all seals and gaskets are in good condition.


By following these simple maintenance tips, you can help ensure that your centrifugal pump will provide years of trouble-free operation.


Here are some tips on how to maintain your vertical submerged centrifugal pump:

1. Check the level of the oil in the pump regularly. Add oil as needed to keep the level at least halfway up the sight glass.


2. Check the condition of the pump's bearings and seals regularly. Replace them if they show signs of wear or damage.


3. Grease the bearings every 500 hours of operation or as needed.


4. Inspect the impeller for damage or wear every 500 hours of operation or as needed. Replace it if necessary.


Common problems and solutions of vertical submerged centrifugal pump


A centrifugal pump is the most common type of pump used in industry today. Centrifugal pumps are used in everything from small, home water systems to large, industrial applications. While centrifugal pumps are very versatile and can handle a wide range of liquids, they are not without their problems. Here are some of the most common problems associated with centrifugal pumps and their solutions.


1) Cavitation

Cavitation is one of the most common problems associated with centrifugal pumps. Cavitation occurs when there is a loss of suction in the pump, causing it to “cavitate” or form bubbles. These bubbles eventually collapse, causing a loud noise and damage to the pump.


Solution: The best way to prevent cavitation is to ensure that the suction line is properly installed and free of any leaks. Additionally, the use of a check valve in the suction line can help to prevent cavitation by keeping liquid from flowing back into the pump.


2) Pump Stalling

Another common problem with centrifugal pumps is “pump stalling”. Pump stalling occurs when the


-Pump not priming: Air in the system, check for leaks, check valves

-Pump is vibrating: Check for loose parts, check alignment

-Pump is making noise: Check for worn parts, check for air in the system

-Pump is leaking: Check seals and gaskets, check for cracks or holes in the pump body
