The ZC Screw Pump, a precision-engineered positive displacement pump intended for steady slurry feeding in severe industrial settings, is supplied by Shaanxi Xixian New Area Zhongcheng Machinery Manufacturing Co., Ltd. This pump guarantees non-pulsating quantitative feeding without material damage, with a capacity range of 10-90 m³/h and input sizes ranging from 80-200 mm. Our system, which is manufactured in accordance with ISO 9001/14001/45001 standards and has been approved by HSE, TÜV, and BV, easily adapts to complicated slurries in the food, chemical processing, oilfield solid control, and sludge treatment industries. ZC Machinery provides individualized customization with 15-day delivery for custom orders, supported by more than 30 years of manufacturing experience and factory-direct prices.
Traditional centrifugal pumps struggle with high-viscosity fluids and abrasive slurries. You need a solution that maintains steady flow independent of viscosity variations.
The positive displacement concept underlies the operation of the screw pump. Fluids are moved axially through a sealed compartment by one or more rotating screws. This eliminates pulsation that harms downstream instruments by producing a steady volumetric flow.
Your process becomes much more stable. High-solid-content slurries and air-entrained media that would clog traditional equipment are handled by the pump. Your operational problems with hydraulic transfer systems are directly addressed by this feature.
Understanding your pump's capabilities helps you make informed decisions. Here are the detailed specifications:

Your production demands reliability. Our pump delivers strong self-priming performance and maintains high conveying efficiency throughout operation. The consistent flow rate remains stable even as viscosity fluctuates, unlike centrifugal alternatives.
You deal with difficult materials. High-viscosity media with particles and suspended solids are smoothly transported by this pump. The equipment adjusts to your unique needs, whether you are working with chemical slurries, drilling mud, or crude oil.
Downtime costs you money. The compact structure enables convenient disassembly and straightforward daily upkeep. Your maintenance team can inspect seals and bearings every 2,000-4,000 hours without specialized tools.
Your workplace environment matters. Low operating noise ensures long-term stable production without disrupting your facility operations. The minimal internal turbulence reduces wear and extends service life.
You face unique challenges in oilfield operations. Our pump excels in multiphase pumping and heavy crude oil transfer. It handles varying gas-to-oil ratios and abrasive particulates without losing prime. Your solid control systems benefit from consistent mud circulation.
Municipal and industrial sludge requires careful handling. The non-pulsating flow prevents settling and maintains homogeneity during transfer. Your treatment processes achieve better efficiency with predictable flow rates.
Shear-sensitive chemicals demand gentle handling. The pump's smooth operation preserves molecular integrity while moving corrosive or reactive media. Your process yields improve through reduced product degradation.
You must maintain product quality and hygiene standards. The pump transports pastes, syrups, and dairy products without structural damage. EHEDG and 3-A compliance options ensure sanitary operation in your production lines.
Confined spaces require compact, reliable equipment. This pump serves as a fuel oil service pump and lube oil circulation unit. Your systems maintain constant pressure with minimal vibration in high-demand environments.
The Screw Pump is an investment that merits thorough verification. We use thorough quality inspections in our manufacturing process.
Before shipping, hydrostatic testing at 1.5 times the maximum operating pressure guarantees the integrity of the casing. Dynamic rotor balancing increases operating life by preventing premature bearing failure.
We verify performance curves (Flow vs. Pressure vs. Power) to guarantee compliance with your duty point specifications. Stator Elastomer Testing confirms chemical compatibility and wear resistance for your specific media.
Material traceability through MTRs (Material Test Reports) covers all wetted parts. Your equipment meets API 676 standards for oil and gas applications, ensuring mechanical reliability under extreme conditions.
Our 6,300 square meter manufacturing plant in Xingping City can produce 200 full systems annually. By doing away with middlemen, direct manufacturer control gives you competitive price and quality control.
Your application has unique requirements. We customize dimensions, motor brands (domestic or international), and material specifications. Whether you need specialized coatings for abrasive service or hardened rotors for extended wear resistance, we adapt to your needs.
Time-to-operation impacts your project timeline. In-stock products ship within 3 days. Custom orders deliver within 15 days from order confirmation. Our partnerships with logistics providers ensure efficient transport to Tianjin and Shanghai ports for global distribution.

Our professional service team provides complete project solutions from initial design through commissioning and beyond.
Q: Can this type of pump run dry?
A: No, the fluid acts as a lubricant between rotor and stator. Dry running for even short periods causes catastrophic stator failure. Always ensure continuous liquid supply to protect your equipment investment.
Q: How does viscosity affect performance?
A: Unlike centrifugal pumps, flow rate remains relatively constant as viscosity increases. Power consumption rises due to internal friction, but your flow predictability improves significantly. This makes dosing applications highly accurate.
Q: What causes premature stator wear?
A: High abrasive content or operating beyond rated pressure/speed are primary causes. We offer specialized coatings and hardened rotors to mitigate this issue in demanding applications.
Q: Is the pump suitable for dosing?
A: Absolutely. The linear relationship between speed and flow makes it excellent for precise volumetric dosing in chemical processing. Your batch consistency improves through accurate metering.
Q: What is the typical maintenance cycle?
A: Depending on your media, inspect seals and bearings every 2,000-4,000 hours. Check rotor/stator clearance during annual shutdowns to maintain efficiency. This preventive approach maximizes your equipment uptime.
Q: Can the pump handle gas-entrained fluids?
A: Yes, the positive displacement design accommodates air-entrained media without vapor lock. Your multiphase applications benefit from uninterrupted operation even with varying gas content.
