Product Detail


Product Tags

12x10G-TG Gravel pump is designed specifically for continuous pumping of extremely aggressive slurries, with a wide particle size distribution. Capable of handling large particles at consistently high efficiencies results in low cost of ownership. The large volume internal profile of the casing reduces associated velocities further increasing component life. 12×10 Sand Gravel Pumps are used to delivery slurry in mining, explosive sludge in metal melting, grudging in dredger and course of river and other fields.

Design Features:

• Advanced hydraulic model, CAD 3D design, high efficiency and obvious energy-saving
• Large dredging sand depth, high density of dredging mud, good pump NPSH and strong suction lift ability.
• Strong through-put, The dredging pump can persistently discharge gravel, high plastic soil lump,etc.
• Wide application, The sand pump can be used in various kinds of soil quality.
• The G sand pump can be directly matched with electric motor or diesel engine.
• The G sand pump impeller is 3 or 5 vanes for large particles delivering.
• Little hydraulic loss, high efficiency and low oil-consumption.
• Steady operating, little vibration, low noise.
• Simple & reliable construction, easily disassembly & assembly, convenient maintain.
• Reliable sealing without leakage.
• Long operating life of wear parts.

12x10G-TG Dredging Sand Pump Shaft Seal Arrangement

• Packing Seal is a general shaft seal.It applies to various pumping conditions, PTFE and Graphite materials of Packing can be used in high corrosive slurries or high temperature conditions.Using ceramic shaft sleeve,For high abrasion conditions, The ceramic shaft sleeve is available.

• Expeller Seal is an impeller force of reversed centrifugal force, preventing slurry leakage. Expeller seal can be used on the single-stage pump when the positive pressure of pump inlet is no more than 10% of pump outlet pressure or on the first-stage pump in the pump series.

• Mechanical Seal is advanced sealing technique without sealing leakage, integrating construction, convenient installation & replacement, various constructions suit for all kinds of conditions.
