Product Detail


Product Tags

14x12T-TG Gravel pump is designed specifically for continuous pumping of extremely aggressive slurries, with a wide particle size distribution. Its wear parts made from high chrome alloy, The hardness can upto HRC65, 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.

 Design Features

• Bearing assembly — Large diameter shaft with short overhang helps extend bearing life.
• Linings — Easily replaceable linings are bolted rather than glued to the housing for active maintenance.
• Housing — Semi-cast iron or ductile iron housing provides high working pressure capability.
• Impellers — Front and rear shields are equipped with pumping blades to reduce recirculation and seal contamination.
• Throat bushings — Use tapered bushings to reduce wear and simplify maintenance.
