AJG Series: Sand Gravel Pumps
Type 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, good
anti-cavitation performance and easy to install.It is applied to
conveying of sands, mud and slurry with bigger solid particles.
Sand Gravel Pumps Working Range
Discharge Diameters - 4to 12 (100mm to 300mm)
Flow Rate to 4,100m3/h
Head Range to 70m
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.
