    Sand Gravel Pump Features
    IMPELLERS - Front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Optional castings of straight or semi-Francis vanes (from 3 to 8 vanes on certain sizes) offer wider hydraulic options in single sizes
    NPSH - Exceptional NPSHr conditions due to large impeller eyes
    EXPELLER SEAL - available with low flow water flush or zero flow (grease lubricated) options to provide exceptional sealing where water introduction to the seal is intolerable or limited
    STUFFING BOX - gland sealing with packing and lantern ring
    BEARING ASSEMBLY - Bearing assembly is adoptable of cylindrical structure, it is easy to adjust the space between impeller and front liner . Can be removed completely when repaired. Bearing assembly use grease lubrication
    BASE - A single piece base cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.


    Applications
    AJG series Sand Gravel pumps are designed for handling the most difficult higher abrasive slurries, which contain too big solids, to be pumped by common pumps, suitable for delivering slurries in mining, explosive -sludge in metal melting, dredging in dredger and course of rivers, and other fields.
