Tips And Solutions For Common Double Screw Pump Problems

Twin screw pumps are essential components in a wide range of industrial applications and are renowned for their efficiency and reliability. However, like any mechanical system, they can also encounter problems that affect their performance. In this blog, we will explore common problems associated with twin screw pumps and provide practical tips and solutions. In addition, we will highlight the advantages of W and V-type twin screw pumps with external bearings, which are designed to increase operational reliability and service life.

Common problems with Double Screw Pump

1. Cavitation: Cavitation occurs when the pressure within the pump falls below the vapor pressure of the liquid, causing vapor bubbles to form. When these bubbles collapse, they can cause serious damage to pump components.

Solution: To prevent cavitation, ensure the pump is sized appropriately for the application and that the inlet pressure remains above the required level. Regularly check the suction line for blockages that could affect flow.

2. Wear: Over time, the internal components of a twin screw pump will wear, especially if the pump is not adequately lubricated.

Solution: Our W, V twin screw pumps feature internal bearings that use the pumped medium to lubricate the bearings and timing gears. This design minimizes wear and extends the life of the pump. In addition, regular maintenance checks should be carried out to detect signs of wear at an early stage.

3. Seal Failure: Seals are critical to preventing leaks and maintaining pressure within the pump. Seal failure can result in fluid leakage and reduced efficiency.

Solution: Check seals regularly for signs of wear or damage. Replacing seals as soon as they show signs of wear can prevent more serious problems later. Our pumps are designed with high-quality materials to extend the life of the seals.

4. Overheating: Overheating can cause pump failure and reduce efficiency. This can be caused by excessive fluid viscosity, insufficient cooling, or excessive friction.

Solution: Make sure the pump is operating within the recommended temperature range. If overheating occurs, consider using a cooling system or reducing the pump speed. Our twin screw pumps feature an external bearing design that helps dissipate heat more effectively, ensuring reliable operation.

5. Vibration and noise: Abnormal vibration and noise may indicate misalignment, imbalance or other mechanical problems inside the pump.

Solution: Check the alignment of the pump and motor regularly. If vibration persists, a thorough inspection of the pump assembly may be necessary. Our pumps are manufactured with imported heavy-duty bearings to ensure smooth operation and minimize vibration.
