Custom Small Submersible Pumps Manufacturers

Submersible electric pumps are small and reliable pump products. They are widely used in farmland irrigation and drainage, industrial and civil construction site water supply and drainage, fountain projects, water diversion in hilly and mountainous areas, and drainage in low-lying areas. Usually, the pump-machine integrated design is adopted, which has a compact structure, is easy to install and disassemble, occupies a small area, and saves space. This design makes the installation process easier and also facilitates maintenance and repair. Usually, stainless steel is used, which has the characteristics of rust resistance, corrosion resistance, and pollution-free, and is suitable for environments with high hygiene requirements or mild corrosion. It has the characteristics of extra-large flow, can provide a larger flow at the same volume, has high efficiency, and low current, realizing the combination of small volume and high flow. It is very convenient to use and can be directly put into the water without connecting a suction pipe. The pump body is equipped with a filter, which can pump liquids containing particles, impurities, oil, etc., and can even pump high-viscosity liquids.

Common Failure Diagnosis and Maintenance Guide for Small Submersible Electric Pumps

As a comprehensive pump company that has been deeply involved in the pump industry for more than three decades, Tefusen (Guangde) Intelligent Technology Co., Ltd. has rich experience in design, production, and sales. We know that to ensure the stable and efficient operation of small submersible electric pumps, daily failure diagnosis and maintenance are crucial. Here are some common problems and their solutions for these types of pumps, as well as maintenance tips to extend their service life.

1. Common Failure Diagnosis and Troubleshooting

1.1. The pump fails to start or suddenly stops during operation

  • Power Issues: First, check the power outlet, cable, and fuse. Ensure the power connection is normal and the voltage is stable.
  • Motor Overheating: If the pump runs for too long or operates in low-water conditions, the motor may overheat, and the internal thermal protector will cut off the power. Please turn off the power and wait for the motor to cool down before restarting.
  • Foreign Object Blockage: If the impeller or suction port is tangled or blocked by sand, debris, or other foreign objects, it will prevent the motor from rotating. Please turn off the power and clear the impeller and suction port.

1.2. Insufficient pump head or decreased flow

  • Impeller Wear or Damage: After long-term use, the impeller may wear out, leading to a decrease in pumping capacity. You should regularly check the condition of the impeller and replace it when necessary.
  • Pipe Leakage: Check the discharge pipe and connectors for leaks. Leaks will reduce the pumping pressure, thereby affecting the head.
  • Suction Port Blockage: Check if the suction strainer is blocked by dirt, causing poor water intake.

1.3. Abnormal pump noise or increased vibration

  • Bearing Wear: Bearings are a key component for the smooth operation of the pump. If the bearings are worn, they will produce a harsh grinding noise.
  • Unbalanced Impeller: Uneven dirt attached to the impeller or damaged blades can cause it to lose balance, leading to severe vibration.
  • Internal Motor Failure: If the noise comes from inside the motor, there may be a problem with the stator or rotor, which requires inspection by a professional technician.

2. Daily Maintenance and Care Tips

In addition to timely diagnosis and troubleshooting, regular maintenance can effectively extend the service life of the pump.

  • Regular Cleaning: Periodically clean the dirt and attachments on the pump's surface, especially the impeller and suction port. This is especially important for submersible pumps operating in sewage.
  • Check Seals: Seals are critical for preventing water from entering the motor. Check the seals for signs of aging, cracking, or wear.
  • Storage Method: When the pump is not in use for a long time, it should be taken out of the water, thoroughly cleaned, and dried. Store it in a dry, ventilated place away from direct sunlight.

By following the above troubleshooting and maintenance steps, you can ensure that the various submersible pump products from Tefusen (Guangde) Intelligent Technology Co., Ltd., including submersible pumps, sewage pumps, and deep well pumps, always maintain their best working condition.
