ZJ Slurry Pump

Description

The ZJ slurry pump offers a wide operating range, with flow rates from 4.5 to 2,200 m³/h, heads up to 130 m, and particle‐handling capabilities up to 180 mm—this pump excels in demanding industries like mining, power generation, coal preparation, and dredging. Its versatile sealing options (packing, mechanical, or expeller), multiple drive configurations (direct, belt, VFD), and adjustable discharge orientation ensure seamless integration into your process line. Easy to maintain, low in vibration and noise, and built for long service life—the ZJ Slurry Pump delivers hard‑wearing performance when it matters most.

Key Features

1. Heavy-Duty Pump Design
   Single-stage, single-suction, overhung shaft, centrifugal pump with a robust double-casing structure—built for reliable horizontal slurry transport in the harshest environments.
2. Integrated Base with Adjustment Mechanism
   A single-piece base includes a built-in mechanism for easy impeller clearance adjustment. The bearing assembly is securely mounted using six or eight heavy-duty bolts, ensuring structural rigidity.
3. Precision Bearing Assembly
   Assembled with high-quality tapered roller bearings in clean environments to prevent contamination. Oversized shaft diameters and reduced overhang improve durability and operational life.
4. Wear-Resistant Impeller Options
   Hard metal impeller with pump-out vanes on both front and rear shrouds reduces internal recirculation and protects seals. Available in straight or semi-Francis vanes to suit various hydraulic requirements.
5. Heavy-Duty Hard Metal Liners
   Liners are made of wear-resistant materials and attached to the casing with a reliable threaded bolt system, replacing traditional glue methods for enhanced safety and durability.
6. Adjustable Throatbush
   Throatbush design allows fine-tuning via cotters to compensate for wear over time, optimizing pump efficiency and extending component life.
7. Reliable Sealing System
   Multiple sealing options are available—including packing seal, expeller (centrifugal) seal, and mechanical seal—to prevent slurry leakage under various working conditions.
8. Modular Design for Easy Maintenance
   High level of part standardization ensures simplified maintenance, lower spare parts cost, and easy interchangeability across models.
9. Flexible Impeller Configurations
   Wide selection of impellers, including standard 5-vane, high-efficiency 4-vane, and non-clogging 2-vane designs, to suit different slurry types and applications.
10. Interchangeable Lining Materials
    Optional lining in 27% chrome alloy, thick rubber, or polyurethane—all interchangeable to match specific abrasion or chemical resistance needs.
11. High-Strength Casing
    Standard ductile iron pump casing resists high working pressures, offering structural integrity in demanding operating conditions.
12. Premium Brand Bearings
    Equipped with bearings from trusted global brands to ensure long service life, improve system reliability, and reduce lubrication costs.
13. Multi-Purpose Platform
    Standardized and modular design reduces inventory requirements while supporting a broad range of operating conditions with fewer parts.
14. Versatile Drive Configurations
    Compatible with various drive types (ZVZ, DC, CV, CRZ), allowing adaptation to different motor setups, space constraints, and performance needs.
15. Adjustable Discharge Direction
    The pump’s discharge outlet can be oriented in any of eight 45-degree positions, allowing flexibility for various installation layouts.
