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,
Operating temperature: T ≤ 100 ℃
 
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.
