ZGB Middle Slurry Pump

Type ZGB pumps are single-stage, single-suction, cantilevered, double casing, horizontal, centrifugal slurry pump. They are designed for conveying abrasive or corrosive slurries in the power, metallurgical, mining, coal, building material and chemical industry ect. Especially in the power plant ash remote transfer condition. This series of pump with high flow and high head can be used Multistage.

Structural features
★ Adopted oil lubrication and the shaft with lubricating plate, with the rotation of the shaft drives the circulation of the lubricating oil. The lubrication cooling bearing shaft, the seal adopts the labyrinth seal. Reliable operation, long life and without leakage.
★ High strength and rigidity horizontal split-case frame assembly with the rotor by means of the adjustment bolt to adjust rotor.
★ 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 expeller seal combined with packing and mechanical seal are optional
★ A variety of wear-resistant high hardness materials are optional to suit different working conditions.The deputy vanes in both former and rear cover of Impeller relieve seal pressure and minimize recirculation. The impeller adopts screw connection
★ Casing is made of ductile iron,ribs help casing to stand high pressure.




Seal Options
Expeller seal combined with packing- The expeller generates a reverse contrifi^al force to prevent the leakage, with muttiple-dtsc packing to combined seal, applied to can't used the expeller alone due to the high pressure suction, expanded the seal using range. The water pressure of the shaft seal ts 0.2-0.3Mpa. As to multi-stage pump, the sealing water perssure of each stage of pump is higher 0.1 Mpa than pump discharge pressure.
Mechanical seal- Suitable for applications where no extra substance is allowed to mix with the fluid being pumped, such as chemical or food industry.
