Type AH, HH slurry pump in cantilevered horizontal / single stage
Type ZH(=AH) pumps are single-stage, single-suction, cantilevered,
double casing, horizontal, centrifugal slurry pump. They are
designed for conveying strong abrasive slurries in the mining,
metallurgical, power, chemical, papermaking building material industry ect. This series of pump is suitable for
low flow, high concentration and high head working condition, especially suitable for the high
head working condition that Single-stage pump can’t delievery.
40-80% for higher density, strong abrasive slurries
40-100% for mediumr density, medium abrasive slurries
40-120% for lower density, lower abrasive slurries
★ A large diameter with a short overhang ensure the rigidity of
shaft, suitable for high power condition.
★ Hardened stainless steel shaft sleeve with ‘O’ ring seals at both
ends. A slip fit allows the sleeve protects the shaft from the wear
★ The deputy vanes in both former and rear cover of Impeller
relieve seal pressure and minimize recirculation.
★ Casing is made of ductile iron,ribs help casing to stand high
★ The wet parts are made of high-chrom alloy or rubber, to resist
wear,corrosion,erosion or impact, parts made of metal or rubber are
★ The shaft seal may be adoptable of packing seal,expeller seal and
mechanical seal to fit different working conditions.
★ The discharge branch can be positioned at intervals of 45 degrees
by request and oriented to any eight positions to suit
installations and applications.
★ The bearing assembly have the grease lubrication and oil
lubrication are optional depend on the usage.
★ Adopted the oil lubrication bearing assembly can effectively
lower the high operating temperature and reduce bearing fault
★ The grease lubrication bearing assembly easy installation and
adjustment, simple structure and easy to maintain and perform
Glond seal - Most popular type of seal. Clean water at a certain
pressure being injected into the packing through the lantern
restrictor, preventing leakage from casing. Simple structure, easy
maintenance and low cost, suitable for where expeller seal
Expeller seal- The expoller generate a reverse centrifugal force to
prevents the leakage. It can be used for single-stage pump or the
first pump of multiple pumps in series when the positive pressure
at suction side is larger than that at discharge side by no more
than 10%. No gland water is needed, the slurry will not be diluted
and the sealing effect is reliable, used in where dilution of
slurry is not allowed.
Mechanical seal - Suitable for applications where no extra
substance is allowed to mix with the fluid being pumped, such
aschemical or food industry.
