Frequently Asked Questions

1. What are the primary applications for the GSX series pumps?

They are designed for transporting fresh water and similar liquids in water supply/drainage systems, steel industry cooling, petrochemical plants, and thermal power generation.

2. What high-performance materials are used in construction?

The standard model utilizes ZG07Cr19Ni10 for the impeller, 40Cr for the shaft, and HT250 for the pump body to ensure durability and efficiency.

3. Does the GSX pump support reverse rotation?

The pump features a bold shaft design that allows for short-time inversion and uses a common shaft suitable for both forward and reverse rotations.

4. How is the vibration minimized in this pump model?

Vibration is minimized through a double-volute chamber that balances radial forces and a staggered blade design that ensures a smooth flow state and low pulse.

5. What sealing options are available for the shaft?

Users can choose between non-asbestos soft packing, mechanical seals (supplied as standard), and injection-type soft packing based on their specific needs.

6. Can this pump handle high-temperature liquids?

Yes, for temperatures exceeding 80ºC, the pump can be configured with a water-cooling structure for the bearings and specialized casing materials like QT500-7.
