Zj Centrifugal Slurry Pump

Single-stage, single-suction, double-casing centrifugal slurry pump designed for continuous handling of abrasive and corrosive slurries containing solid particles.

Key features

• Construction: Available in horizontal (ZJ) and vertical (ZJL) configurations to suit site layout and installation constraints.
• Hydraulic design: Based on advanced two-phase (solid–liquid) flow theory to improve efficiency and reduce wear.
• Wear parts: Pump casing and cover use replaceable metal liners made from high-chromium, wear-resistant alloy to extend service life and reduce operating costs.
• Solids handling and temperature limits: Suitable for mixed mortar solids concentrations up to ~45% and mine slurries up to ~60%; recommended medium temperature up to 60 °C.
• Mechanical layout: Double-casing structure with a cylindrical bearing assembly that allows axial clearance adjustment between the impeller and front guard plate; bearing assembly can be removed as a whole for rapid maintenance.
• Sealing options: Packing seal, expeller (vane) seal, or mechanical seal to match process requirements and minimize leakage.
• Lubrication: Bearings lubricated with grease for straightforward on-site maintenance.
• Installation flexibility: Pump outlet can be oriented at eight different rotation angles to simplify piping layout.
• Drive options: Compatible with V-belt drives, elastic couplings, gearboxes, hydraulic couplings, or frequency-conversion (VFD) drives for optimized matching to drivers and energy-saving operation.

Benefits for industrial users

• High efficiency and energy savings from optimized hydraulics.
• Long service life and reduced downtime due to replaceable high-chrome wear liners.
• Compact, lightweight design with straightforward maintenance access.
• Adaptable sealing and drive options to fit a wide range of process conditions.

Typical applications

• Mineral processing and mining
• Power plants and ash handling
• Metallurgy and metal finishing
• Coal handling and preparation
• Building materials and slurry transport

Options and customization

• Multiple impeller materials and liner alloys for specific slurry chemistries and abrasiveness
• Choice of seal type and drive arrangement
• Custom outlet orientation and mounting arrangements

For specification-driven procurement, provide required flow, head, particle size/concentration, temperature, and preferred seal/drive options so the correct ZJ/ZJL configuration and materials can be recommended.
