AJH Series: High Head, Heaviest Duty Slurry Pumps
AJH series pump were designed to produce high heads per stage at high pressures. Commonly
used for long distance transport lines, the AJH lines can often satisfy application duties with a single
pump where others require multiple pumps.The range is capable of handling medium size particles
and pumping at heads in excess of 90 meters per stage.
High Head Slurry Pumps Working Range
Discharge Diameters - 1" to 4" (25mm to 100mm)
Flow Rate to 720m3/h
Head Range to 118m
High Head Slurry Pumps Features
IMPELLERS - Various of metal and elastomer interchangeable. Front and rear shrouds have pump out vanes that reduce recirculation and seal contamination
LINERS - Various of metal and elastomer interchangeable. Easily replaceable liners are bolted, not glued to the casing for positive maintenance
THROATBUSH - Various of metal and elastomer interchangeable. Wear is reduced and maintenance simplified by the use of tapered.
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
CASING - Casing halves of cast or ductile iron provides high operating pressure capabilities
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
AJH pumps are used to pump high-hardness, strong-corrosion and high-concentration liquids that contain suspended solid particles, such as finished ores, refuse ores, ashes, cinders, cements, mud, mineral stones and etc. in the industries of metallurgy, mining, coal, power, building material and etc. The temperature of the pumped solid-liquid mixture should be ≤80℃， and the weight concentration should be ≤60.

The Aojin range of AG pumps is designed specifically for continuous use in slurry type applications with larger or breakage sensitive particles. This range of vortex pumps is capable of handling large as well as very soft particles, especially where particle degradation is of concern. The large volume internal profiles, combined with the recessed open impeller design, reduce particle interaction and limit potential blockages.
