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 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.
संरचना विशेषता
★ 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, having the abrasion-resist, corrosion-resist and impact erosion-resist properties, improved the service life of pump.
★ The wet parts are made of metal or rubber are interchangeable or mixed use, suited different working condition.
★ Impeller adopt the method of wide flow and vane concave to improve flow and corrosion resistance, prolong service life.
★ 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 oli 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.
