Get Quote NowAs Romania continues to align its heavy industries with EU environmental directives, mining operators and municipal infrastructure managers face the critical challenge of handling highly abrasive waste slurries. From the copper deposits at Cupru Min Abrud and gold extraction operations in the Apuseni Mountains to coal-washing circuits in the Jiu Valley, the demand for reliable vertical slurry pumps has intensified.
Additionally, the transition away from coal-fired power generation in regions like Gorj and Hunedoara requires robust slurry pumping technology for ash-pond decommissioning and environmental reclamation. Traditional horizontal pumps struggle under shallow sump configurations and high-concentration solids. The mechanical demand requires submerged vertical designs with cantilevered shafts that eliminate the need for submerged bearings and mechanical shaft seals—maximizing operational uptime.
Tailings in Romania often combine sharp silicate particles with corrosive wastewater containing residual processing acids. Standard cast-iron alloys fail rapidly under these synergistic wear mechanisms.
Our vertical slurry pumps omit submerged bearings and lip-seal packings, which are the main failure points when handling fluids with high solid volume percentages.
By using silicon carbide ceramic inserts for impeller and lining design, we extend equipment lifespans up to 5 times compared to standard duplex steel configurations.
Aligning European engineering standards with the agile production capabilities of China's leading listed industrial manufacturer.
Western European heavy industrial brands are facing prolonged material procurement delays, with turnaround times for custom-cast impeller parts exceeding 20-30 weeks. This risks extended downtime for mining operations in regions like Hunedoara.
Operating a 430,000 m² high-standard modern industrial park, we maintain fully integrated casting, CNC machining, and automated dynamic balance testing facilities. This cuts production cycles down to 4-6 weeks for custom vertical slurry setups.
Listed on the Shenzhen Stock Exchange (Stock Code: 002598), Shandong Zhangqiu Blower is a transparent, state-compliant entity with a clear track record of delivering certified machinery globally.
Originally established in 1957, Shandong Zhangqiu Blower Co., Ltd. (formerly Shandong Zhangqiu Blower Works) has led the development of fluid machinery technology in China.

Get Tech SpecsDeveloping industrial pumping systems requires deep local engineering knowledge. Our project applications focus on three key sectors in Romania:
1. Metal Ore Flotation & Tailings HandlingIn the copper extraction areas of the Apuseni Mountains, vertical slurry pumps manage flotation slurries, thickener underflows, and tailings disposal. Our silicon-carbide lined components are engineered to withstand abrasive mineral mixtures and process chemical residues.
2. Heavy Ash DecommissioningRomanian coal facilities rely on slurry systems to clear ash deposits. Vertical cantilever pumps run continuously in these sumps, handling fly-ash sediments that would quickly erode standard water pumps.
3. Municipal Wastewater Treatment & Digester RecyclingWith major EU funds supporting municipal infrastructure upgrades, our air foil bearing turbo blowers and submerged sludge pumps help modern sewage systems optimize aeration performance.
As standard metal impellers degrade in corrosive and abrasive solutions, ceramic linings are becoming the preferred choice for heavy mineral processors due to their significantly longer operating life.
Avoiding costly maintenance downtime remains a top priority. Our cantilevered vertical pumps operate without submerging shaft seals or bearings, preventing seal-failure blockages in pit excavations.
High power costs in Europe make energy-efficient motors and hydraulic pump profiles essential for reducing utility bills in heavy continuous operations.
Our facility runs advanced Product Lifecycle Management (PLM) and Computer-Aided Manufacturing (CAM) systems. By integrating Computer-Aided Process Planning (CAPP) and Computer-Aided Testing (CAT), we maintain tight machining tolerances across our product lines.
Our heavy machining workflow includes Japanese-built multi-axis CNC milling centers and ultrasonic non-destructive testing machines. These units inspect internal steel structures, ensuring our slurry pumps can operate under constant high pressures.
Our engineers also optimize the hydraulic paths of each pump casing to reduce internal friction. This lowers energy usage while maintaining stable flow rates, matching standard EU efficiency metrics.
