Gravel Pump

Key Applications

Transporting coarse materials including granular coal, metallurgical slag, and root crops

Supporting river dredging, river restoration, metal mining, ore extraction and industrial smelting operations

Performance Characteristics

This gravel pump excels in demanding applications involving high-volume flows, elevated concentrations, and substantial head requirements. Its superior cavitation resistance and exceptional wear durability make it particularly suitable for handling high-temperature, highly abrasive slurry mixtures.

1. The robust high-strength bracket and simplified bearing assembly of the gravel pump*utilize a bolted connection, facilitating straightforward installation, disassembly, and impeller clearance adjustment.

2. The discharge outlet can be positioned at any angle, providing enhanced flexibility and convenience for maintenance operations.

3. Customers can select between packing seals or auxiliary impeller seals based on specific application requirements.

4. Key wet-end components, including the pump casing, impeller, as well as the front and rear wear plates, are constructed from high-chromium wear-resistant alloy, ensuring the extended service life of the gravel pump

5. The single-volute casing design combined with wide fluid passages ensures the unimpeded transport of large solid particles, while also delivering strong resistance to cavitation and abrasion.
