Cavitation Affects The Stainless Steel Submersible Pump System

  • There are many factors that determine the service life of Stainless Steel Submersible Pump. The following are common problems that affect the pump system.


    Cavitation occurs when air bubbles gather around the impeller of the pump. Air bubbles can form in any liquid in the pump, including water or oil. The bubbles subsequently burst, causing shock waves in the flowing fluid and inside the pump, and may damage the impeller or pump housing.

    Incorrectly installed pumps are the most common cause of cavitation. When the pump is operated at a lower or higher temperature than its designed pressure, cavitation will occur. To avoid this, always consult a professional to evaluate your needs and recommend the right pump for the process you are running.

    Use impellers made of high-strength materials in the pump system. Always run the pump at the proper pressure and temperature.

    Pump technicians can verify that your pump is operating under the correct operating conditions and resolve possible problems before the impeller is completely damaged.

    1. The pump curve is lower than normal

    The pump curve is the data that compares the pump's ability to push liquid or generate flow with the maximum pressure it can deliver, which is also called the pump head. Pumps operating below its standard curve should cause concern. Possible reasons for poor pump bending performance are blockage or damage of the impeller, blockage of the volute or wear of the sealing ring.

    Preventive maintenance ensures that the pump always runs on its standard curve, so that the speed and flow are consistent. During routine maintenance, technicians will measure the flow and total head of the pump and compare them with the standard curve of the pump.

    If the pump is running below the curve, then a technically savvy person can diagnose the root cause and suggest solutions to increase system flow and save you unnecessary replacements.

    Leaks, low flow, and other pump problems will not only reduce pump efficiency but also damage other equipment. Experienced engineers will provide solutions to prevent further damage to the pump system, extend its service life, and minimize your operating costs.

    If the pump is operated at varying pressure levels, temperatures, and other variables, this will cause losses to the pump. Correct troubleshooting can help identify common faults and restore the pump to its optimal capacity. Therefore, it is necessary for the professional technicians of the Submersible Pump Factory to check your pump system regularly and carry out preventive maintenance to avoid any potential system problems.
