Description

- Commodity name: Hebei Xingou Horizontal ZJ Slurry Pumps (100ZJ & 150ZJ) for Copper Concentrator in Kazakhstan
Hebei Xingou Horizontal ZJ Slurry Pumps (100ZJ & 150ZJ) for Copper Concentrator in Kazakhstan
1. Project Basic Information
Project Location: Large open-pit copper mine in Karaganda Region, Kazakhstan
Client Profile: Local mining group with daily processing capacity of 1,500 tons copper ore. The processing flow includes crushing, ball milling, hydrocyclone classification, flotation and tailings disposal.
Pump Models Supplied: Horizontal heavy-duty ZJ series slurry pumps
150ZJ-I-A50: 8 sets for hydrocyclone feeding (primary grinding circuit)
100ZJ-I-A42: 12 sets for flotation re-circulation & tailings transfer
Delivery Scope: 20 complete pump units (14 running, 6 standby) + full CR27 high-chrome wear parts package, IE3 explosion-proof motors, ATEX certified control panels, V-belt drive assemblies
Production Lead Time: 28 working days; Sea freight to Aktau Port: 36 days; On-site installation & commissioning: 4 days
Stable Operation Record: Continuous running for 16 months after formal commissioning
2. Severe On-site Working Conditions & Original Equipment Pain Points
Harsh Slurry Parameters
Crushed copper ore slurry contains sharp quartz, chalcopyrite and pyrite hard particles; maximum solid particle size reaches 38mm, slurry concentration 40%–55%, specific gravity SG=1.48. Weak alkaline flotation reagents are added, causing mild abrasion & slight corrosion simultaneously.
Extreme Climate Challenge
Kazakhstan mine area suffers huge temperature fluctuation: -35°C in winter and +38°C in summer. Ordinary pumps often face seal cracking and bearing lubrication failure under wide temperature variation.
Main Problems of Former Imported Pumps
Short service life of standard wear parts: Original international brand pumps only ran 30–40 days before replacing impellers and liners, frequent shutdowns reduced copper output.
Extremely high spare part cost & long delivery cycle: Import wear parts took 50–70 days to arrive at Kazakhstan remote mine, leading to massive production loss during maintenance.
Poor low-temperature adaptability: Standard rubber seals became brittle in cold winter, causing slurry leakage and safety risks.
No unified ATEX explosion-proof supporting system: Old electrical cabinets failed local mine safety inspection due to lack of explosion-proof certification.
3. Customized Solution from Hebei Xingou
3.1 High Wear-Resistant Wetted Components Upgrade
All overflow parts (impeller, volute liner, throat bush, frame plate liner) adopt CR27 high chromium cast iron with hardness ≥62HRC. The optimized wide flow channel hydraulic design reduces particle impact velocity, extending wear parts service cycle to 75–95 days, cutting maintenance frequency by over half.
3.2 Low & High Temperature Adaptation Optimization
Fluoro-rubber composite seals resistant to -40°C ~ +150°C, avoiding brittle cracking in frigid winter;
Bearing assembly filled with low-temperature synthetic lubricant, stable operation under extreme cold climate of Kazakhstan steppe;
Reinforced double-layer pump casing with anti-freezing coating to prevent frost crack in outdoor pump houses.
3.3 Complete ATEX Explosion-Proof Matching Package
Full set of certified explosion-proof supporting equipment is supplied together with pumps, including flameproof IE3 motors and ATEX control cabinets, fully compliant with Kazakhstan mining safety regulatory standards, eliminating safety audit obstacles.
3.4 One-stop Spare Part Supply & After-sales Support
A full set of backup wear parts was delivered together with pump units. We also established a regional spare parts stocking plan for Central Asian clients, shortening spare part delivery cycle to within 7–10 days for repeat orders. Our overseas technical team provides remote video guidance and periodic on-site service support.
4. Client Achievements & Feedback
Stable production capacity: Unplanned downtime caused by pump abrasion is greatly reduced, the mine’s actual copper concentrate output increased by around 14%.
Remarkable comprehensive cost reduction: The total investment of our ZJ pumps and spare parts is only 58% of imported international brand pumps, with longer wear component service life to cut long-term maintenance expenditure.
Perfect climate & safety compliance: Custom cold-resistant structure and ATEX explosion-proof configuration fully fit Kazakhstan remote open-pit mine environment, no extra modification required on site.
Reliable localized spare supply chain: Bulk wear parts can be shipped in one consolidated container, no more long waiting for oversea original accessories.
5. Conclusion
Hebei Xingou 100ZJ & 150ZJ horizontal slurry pumps are cost-effective interchangeable alternatives to international heavy-duty mining pumps. The whole set solution perfectly matches high-abrasion, weak alkaline slurry and extreme temperature conditions of Central Asian copper mines. We can provide one-stop supply of slurry pumps, explosion-proof electrical systems and full wear spare parts for all mineral concentrators.
