AJG Series: Sand Gravel PumpsType AJG sand gravel pumps are designed to handle very large particles for gravel and dredging operations.Gravel pump is single-stage single-suction horizontal centrifugal pump, connected by belt. It is light, goodanti-cavitation performance and easy to install.It is applied to conveying of sands, mud and slurry with bigger solid particles.Sand Gravel Pumps Working RangeDischarge Diameters - 4″to 12″ (100mm to 300mm)Flow Rate to 4,100m3/hHead Range to 70mSand Gravel Pump FeaturesIMPELLERS - 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 sizesNPSH - Exceptional NPSHr conditions due to large impeller eyesEXPELLER 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 limitedSTUFFING BOX - gland sealing with packing and lantern ringBEARING 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 lubricationBASE - 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.ApplicationsAJG 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.
