Type Z series Slurry Pump is a new energy-saving centrifugal pump. They are innovative in hydraulic designs, structural designs and materials of castings after integrating congeneric products throughout the world. They have many features: high efficiency, reasonable design, reliable operation, long in service time, easy maintenance, and low running costs and so on.

The Z series pumps are widely used for handling abrasive or corrosive slurries in power, metallurgical, mining, coal, as well as chemical industries. For example, flushing ash in power plants and pumping coal slurry in coal preparation plants. They are suitable for handling abrasive and corrosive solids-bearing slurry with maximum concentrations of wt.45%(ash) and wt.60%(ore).

Structural feature of Z series slurry pumps

Pump Body  It is a horizontal cantilevered slurry double-cases pump. The pump head includes cases, impeller, and shaft seal. Double-cases pump centrally split vertical spilt direction. Discharge port can be positioned at 8 different position at an interval of 45°. The outside cases made by HT200 or HT500-7, connecting with bolts. The inside cases (volute case, front liner, back liner) made by high-chrome alloy or rubber materials.

Impeller  Front and back cover plates with back vanes to reduce leakage and increase operating life, impeller and shaft is firmly connected by ladder-shaped with disassembly ring, "O" rubber ring is used between liner and volute casing and it is very convenient and reliable.

Shaft Seal  Expeller seal and packing seal.

Support  The supports can be lubricated by oil. Supports are made up with support body, support cover, shaft, bearing box, bearing, bearing cover, baffle sleeve, nut, oil seal wash plate and so on (See bellow). The supports have water-cooling above 150Z.
