Discover our foundational fluid-handling machinery, heavy-duty slurry pumps, and high-efficiency roots blowers built for industrial mineral processing plants.
Understanding Fluid Dynamics & Structural Wear in Mining Applications
In mineral processing circuits, froth flotation is critical for separating valuable minerals from gangue. However, transporting the froth or the dense flotation feed poses significant physical challenges. Standard slurry pumps typically fail in these environments due to air binding, cavitation, and extreme abrasive wear caused by mineralized air bubbles that lock the impeller's intake.
As a leading cheap flotation feed pump manufacturer and exporter, Shandong Zhangqiu Blower Co., Ltd. engineering teams optimize froth handling through custom hydraulic design. By incorporating inducer blades and specialized conical impellers, our pumps continuously break up entrained air bubbles. This prevents bubbles from coalescing at the eye of the impeller, maintaining stable discharge rates even when running high-volume frothy mixtures.
Our solutions incorporate proprietary materials, including specialized high-chromium alloys and advanced engineering ceramics (such as our TZJK-TD series ceramic slurry pump), offering wear lifetimes up to three times longer than standard elastomeric or metal alloy liners under aggressive chemical conditions.
Established in 1957, Shandong Zhangqiu Blower Co., Ltd. (ZCBC) is a publicly listed enterprise on the Shenzhen Stock Exchange (Stock Code: 002598). We combine 50+ years of manufacturing experience with robust R&D to deliver high-quality, cost-efficient fluid systems.
With two Sino-Japanese joint ventures and an established USA branch, ZCBC is the pioneer in the Chinese blower and pump industry to develop overseas support infrastructures, ensuring seamless field services in over 70 countries.
Our unified engineering team designs, manufactures, and services Roots Blowers, Centrifugal Blowers, Heavy Slurry/Froth Pumps, Pneumatic Conveying Systems, and MVR Evaporation / Concentration equipment.
We maintain deep academic and research ties with Tsinghua University, Xi'an Jiaotong University, China University of Mining and Technology, and Shandong University, continuously injecting engineering innovations into our slurry-handling designs.
Unlocking Unparalleled Cost-Efficiency, Advanced Metallurgy & Scale Economies
By operating our own advanced foundries, we control the metallurgical chemistry of our pump housings and impellers. This in-house workflow minimizes logistics overhead and external markup, allowing us to maintain a highly competitive price structure.
Our large-scale engineering design center operates 24/7. When procurement managers submit technical requirements, we deliver tailored CAD models, structural analysis, and 3D mockups within 24 hours to accelerate plant retrofitting.
Chinese production is backed by rigorous compliance frameworks. ZCBC is certified under ISO9001 (Quality Management), ISO14001 (Environmental), ISO50001 (Energy Management), and holds mining-safety certifications and CE marks, guaranteeing top-tier structural integrity.

Extending Operational Lifespan in Highly Corrosive Mineral Slurries
When selecting a slurry pump for flotation circuits, the material composition of wet-end components determines the system's runtime. Typical stainless steels degrade rapidly under the combined action of sulfuric acid (often used in copper/gold flotation PH control) and coarse quartz sand particles.
ZCBC works with procurement engineers worldwide to align slurry transportation systems with gas-injection flotation equipment for complete process optimization.
A high-performance flotation circuit requires a balanced ratio of air injection and slurry transport. ZCBC provides a unified solution by pairing our high-efficiency roots blowers (e.g., ZG Tri-Lobe or SSR series) with our froth-optimized slurry pumps, ensuring consistent bubble column density and reliable pulp level control.
For existing facilities facing high maintenance costs, ZCBC provides drop-in replacement wet-end kits. Our custom components retrofitted to third-party pump bodies help operators lower their Total Cost of Ownership (TCO) without requiring extensive piping reconfigurations.
Beyond froth processing, our systems support plant water-loop closures. Our MVR (Mechanical Vapor Recompression) crystallization setups work in tandem with ceramic pumps to treat and recycle tailing water, supporting zero-liquid-discharge (ZLD) plant designs.
ZCBC maintains strict adherence to quality and safety control standards. Below are our internationally recognized certifications.
Utilizing Advanced Machining Centers & Industrial Software Systems
Our modern industrial park features high-precision machinery imported from Japan and Germany. These manufacturing tools allow us to achieve tight clearances in pump impellers and casing components, boosting hydraulic efficiency and lowering energy usage.
We manage product life cycles using PLM (Product Lifecycle Management), CAD/CAM design programs, and CAPP (Computer-Aided Process Planning) software. This digital infrastructure ensures high reproducibility and precision, keeping all replacement parts within tight mechanical tolerances.
Our quality verification process checks every casting using non-destructive ultrasonic testing, computerized static and dynamic balancing, and comprehensive hydraulic performance testing under full-load conditions.
