Working Principle

The G-Type pump operates using a single helical screw that rotates within a stator. As the screw turns, it moves the fluid along the pump's axis, creating a sealed cavity that ensures a continuous and uniform flow. This design minimizes pulsations and shear, making it suitable for delicate or abrasive materials.

Applications

The G-Type Movable Single-Screw Pump is versatile and finds applications in various industries, including:

• Chemical Processing: Handling viscous chemicals and slurries.

• Food & Beverage: Pumping pastes, sauces, and syrups.

• Wastewater Treatment: Transporting sludge and other thick liquids.

• Oil & Gas: Moving crude oil, emulsions, and other heavy fluids.

• Pharmaceuticals: Processing creams, ointments, and other sensitive substances.

Advantages

• High Viscosity Handling: Capable of pumping fluids with viscosities up to 2.7 × 10⁵ cSt.

• Pulsation-Free Flow: Ensures smooth and consistent delivery.

• Self-Priming: Can operate without the need for external priming systems.

• Durability: Constructed with high-quality materials for extended service life.

• Versatility: Suitable for a wide range of applications across various industries.

Installation & Maintenance

Installation:

1. Foundation: Ensure a stable and level base to support the pump.

2. Alignment: Properly align the pump with the drive motor to prevent undue stress.

3. Connections: Connect the inlet and outlet pipes, ensuring they are secure and leak-free.

4. Electrical Hookup: For electric motor-driven pumps, connect the power supply according to the manufacturer's specifications.

Maintenance:

• Regular Inspection: Check for signs of wear or damage, especially on the screw and stator.

• Seal Replacement: Periodically inspect and replace seals to prevent leaks.

• Cleaning: Regularly clean the pump to prevent buildup of materials that could affect performance.

Troubleshooting

• Problem: Pump not starting.

• Solution: Check the power supply and ensure all electrical connections are secure.

• Problem: Loss of suction.

• Solution: Verify that the inlet is not clogged and that the pump is primed correctly.

• Problem: Excessive vibration.

• Solution: Ensure the pump is properly aligned and that the foundation is stable.

• Problem: Leakage.

• Solution: Inspect seals and gaskets for wear and replace as necessary.

Conclusion

The G-Type Movable Single-Screw Pump is a reliable and efficient solution for handling challenging fluids in various industrial applications. Its robust design, combined with its ability to manage high-viscosity and abrasive materials, makes it a preferred choice for many industries. Regular maintenance and proper installation are key to ensuring optimal performance and longevity of the pump.
