Type ZG(H) pumps are single-stage, single-suction, cantilevered, horizontal, centrifugal slurry pump. They are designed for continously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by common pumps. They are suitable for delivering slurries in Mining, Explosive sludge in metal melting, Dredging in dredger and course of rivers, and other filed. This series of pump especially suitable for the high flow, high concentration and high head working condition, good performance of NPSH and high abrasion- resistant, can be widely used in high temperature and strong abrasive slurry transportation.
★ The bolt connect the high strength fram and cylinder bearing assembly are easy to installation and disassemble, and also easy to adjust the impeller clearance.
★ The discharge direction of pump can be oriented in any direction, easy maintenance.
★ Packing seal and expeller seal are optional according to the requirment.
★The wet-parts as casing,impeller,front/back liner are made of high chromium abrasive-resistance alloys that ensure the longlife.
★ The design of this pump is single casing and wide wet-passage that ensure the pass of large particles, good performance of NPSH and high abrasion- resistant.
1.Capacity range recommended 50%Q'≤Q≤110%Q' (Q'=Capacity at Max. eff. point) 2. M means Alloy wear-resistant material, R means rubber
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.
