A newly installed screw pump or one that has been in use for some time may experience reduced flow. This issue can occur due to several factors. Below are the common causes and solutions for insufficient flow in screw pumps.

1. **Insufficient Inlet Flow**: The pump’s inlet might not be providing enough fluid to match the output capacity. This results in low overall flow. To resolve this, increase the inlet flow rate by ensuring the system is properly sized and the supply is adequate. 2. **Leaky Inlet Connections**: Poor sealing at the pipe joints or within the pipeline can lead to air leaks, reducing the effective flow. Check all connections and replace or repair any damaged components. 3. **Clogged Filters or Pipes**: In sludge or thick liquid applications, the inlet filter or pipes may become clogged with debris, restricting the flow. Regular cleaning and maintenance of these parts can prevent such issues. 4. **Damaged Rubber Lining**: Over time, especially when the pump is left idle or used with incompatible fluids, the rubber sleeve can degrade. A worn or damaged sleeve increases the clearance between the rotor and stator, leading to lower efficiency. Replace the rubber sleeve with a more suitable material for the application. 5. **Low Motor Speed or High Viscosity**: If the motor speed is too low or the liquid being pumped has high viscosity, the pump may not deliver the expected flow. Ensure the motor is operating at the correct speed and consider using a pump designed for viscous materials. 6. **Improper Pump Selection**: Selecting a screw pump based on water flow standards without considering the specific gravity or viscosity of the actual fluid can result in underperformance. Always choose a pump that matches the properties of the liquid being handled. Screw pump products include single-screw pumps, I-1B thick slurry pumps, and other specialized models suited for different applications.
