ZJ Series Coal Slurry Pump: High-Efficiency Solution for Abrasive Slurries

Introduction to ZJ Series Coal Slurry Pumps

The ZJ Series Coal Slurry Pump is a single-stage, single-suction, double-casing centrifugal horizontal slurry pump designed to handle highly abrasive and corrosive slurries. Engineered for optimal performance under various industrial conditions, these pumps are widely used in coal washing, mining, power generation, and metallurgical industries. Their adaptability to different speeds ensures efficient slurry transportation with minimal energy consumption.

ZJ Pump is widely used in metallurgy, mining, mineral processing, dredging, de-watering, water treatment, coal washing, mill, cyclone feed, tailing, power, building material...etc. various industrial sites. For different duties, pump is named as High head pump, High pressure pump, Mineral processing pump, Mill discharge slurry Pump, Booster pump, Feeding pump, Tailing pump,Transfer pump Thickner Underflow Pump, De-watering screen pump, Pressure pump, Concentrate pump.

Specification:

Flow rate: 4.5m³/h~4000 m³/h,

Head: H=6m~134m,

Speed: n=590～2950r/min,

Key Features of the ZJ Series Coal Slurry Pump：

● High efficiency; energy-saving; light weight; reasonable construction; reliable performance; little vibration; low noise; easy maintenance.

● Various design of the pump speed and versions enable the pump to work even under poor conditions.

● The bearing layer and the wear layer can be separated. And the wet parts are made from strong abrasion resistance high-chrome alloy cast iron.

● Three types of shaft seals, mechanical seal, packing seal and packing combined expeller seal can be adopted.

● The pump discharge can be positioned to 8 directions at intervals of 45 degrees according to need. The inlet is horizontal.

● The medium transferred temperature should not exceed 60ºC. The weight concentration of the mortar should not exceed 45%; mineral slurry, 60%.

● The pumps can be installed in multi-stages for long distance delivery.

● Drive mode: mainly direct connection(DC).

● Lubricating way: 40ZJ-200ZJ adopts grease or oil lubrication according to bearing box structure; 250-500ZJ adopts grease lubrication.

Applications of Coal Slurry Pumps in Industrial Settings

1. Coal Washing & Processing

Coal slurry pumps play a critical role in coal preparation plants, transporting coal fines, tailings, and dense media. These pumps handle high-density coal slurries, ensuring efficient separation and processing.

2. Power Generation

Power plants use coal slurry pumps for handling fly ash, bottom ash, and coal-water mixtures, reducing waste and improving operational efficiency.

3. Mining & Mineral Processing

In mining operations, ZJ series pumps transport ore slurries, tailings, and thickened concentrates, ensuring a steady flow of materials during extraction and processing.

4. Chemical & Metallurgical Industries

These pumps handle abrasive chemical slurries, metal processing residues, and byproducts in metallurgical plants and chemical industries.

5. Dredging & Sand Handling

With their high-abrasion resistance, ZJ slurry pumps are widely used in dredging, sand mining, and gravel processing.
