Why to choose the sand gravel pumps for slurry suction?

What are the sand gravel pumps?

Sand gravel pumps are essential equipment designed specifically for the continuous pumping of highly aggressive slurries, gravels, and sands with a wide particle size distribution. OCEAN Pump G/GH Sand Gravel Pumps are engineered to handle the most challenging pumping tasks in various industries. With the capability to handle large particles while maintaining high efficiencies, these pumps ensure optimal performance and reduce maintenance costs. The large volume internal casing profile further enhances component life by reducing associated velocities.

In mechanized tunnelling projects, the performance of the Tunnel Boring Machine (TBM) plays a crucial role in adhering to time and cost budgets. OCEAN Pump G series Sand Gravel Pumps are specifically designed to support tunneling projects, including MTBM, TBM, EPB, Slurry Shields, and Segment Shields. These pumps excel at continuously handling highly abrasive slurries with large solids, such as gravels, slurries, sands, bentonite, sandy soil, rock, stone, sludge, and mud.

The reliability of the OCEAN Pump G gravel pump design significantly improves the mean time between failures (MTBF) of the complete machine, ensuring uninterrupted operation and reducing downtime.

The G/GH heavy-duty sand and gravel pump design is not limited to tunneling projects. These versatile pumps are the ideal choice for various industries, including sand and gravel mining, dredging, cutter suction dredgers, sand excavation, coal washing, power plants, mineral processing plants, and long-distance pipeline duties. Their ability to handle high head and high volume duties makes them suitable for applications such as higher head cyclone feed.

What are the design features of the sand gravel pumps?

The OCEAN Pump G/GH Sand Gravel Pumps incorporate several design features that enhance their performance, efficiency, and durability.

a) Segmented Clamp Ring: The larger size units of these pumps are equipped with a unique segmented clamp ring, allowing for casing rotation at any angle. This innovative design reduces the need for costly high-wearing bends and minimizes maintenance requirements.

b) Impeller Expulsion Vanes: These pumps feature impeller expulsion vanes that reduce gland pressure and prevent the intrusion of high concentrations of solids in the gland area. By minimizing suction side recirculation, the pumps maintain their efficiency even in demanding pumping conditions.

c) Specially Designed Impeller Vanes: The pumps are equipped with specially designed and shaped impeller vanes that enable them to handle extraordinarily large particles. The unique casing design combined with sealing vanes prevents the intrusion of abrasive solids at the sealing faces, ensuring reliable operation.

d) Robust Casing: The large, robust casing is designed to reduce internal velocities, resulting in minimal efficiency loss and improved casing wear life. The casing, made up of multiple components, reduces maintenance time and costs associated with a one-piece design.

e) Heavy-Duty Components: These pumps are fitted with heavy-duty grease-lubricated taper roller bearing assemblies, ensuring trouble-free operation. The rigid large-diameter shaft with reduced overhang minimizes deflection and vibration under all conditions. The pumps’ high service factors enable them to handle all radial and axial thrusts effectively.

f) Unique “-10” End Cover Assembly: The pumps are equipped with a unique “-10” end cover assembly, comprising V-seals, double piston rings, and an external flinger with grease-lubricated labyrinths. This assembly provides additional protection and longevity, enhancing the reliability of the pumps.

Conclusion:

OCEAN Pump G/GH Sand Gravel Pumps are the perfect solution for handling aggressive slurries, gravels, and sands in various industries. With their efficient design, reliability, and low cost of ownership, these pumps ensure optimal performance and minimize maintenance requirements. Whether it’s tunneling projects or applications in mining, dredging, or power plants, these pumps deliver exceptional results. Invest in OCEAN Pump G/GH Sand Gravel Pumps for efficient and reliable pumping solutions that withstand the most demanding environments.
