Gravel Sand Pump

​Design Philosophy​​

Gravel Sand Pump is designed by our independent designers who have been paying great attention to it.

High Head Gravel Sand Pump is designed specifically for continous 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.

​Technical Mastery​​

● Construction of this pump is of single casing connected by means of clamp bands and wide wet-passage.  The wet-end parts material is hard alloy has good wear resistance, corrosion resistance and high reliability.
● The bearing assembly is designed with high capacity bearings, and the bearing adopts grease lubrication and oil lubrication to adapt to different working conditions.
● The gap between the impeller and the backliner can be adjusted to ensure the efficient operation of the pump.
● The shaft seal adopts packing seal, expeller seal and mechanical seal to meet the requirements of different working conditions.
● The pump and drive machine can choose DC drive, CV drive, ZVZ and other drive methods.
