YHH High Head Heavy Slurry Pump

Type YHH pumps are single-stage, end-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

M means alloy wear-resistant material


Structural features
★ 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 and corrosion.
★ 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 pressure.
★ 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 interchangeable.
★ 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 reliably.




Seal Options
Gland 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 unsuitable.
 
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.
