Against the backdrop of rapid development in the environmental protection industry, the reliability and adaptability of fluid conveying equipment directly determine the effectiveness of pollution treatment. Whether transporting highly corrosive media in industrial wastewater treatment or delivering high-viscosity materials in municipal sludge disposal, screw pumps serve as core equipment whose performance draws extensive attention. Among numerous screw pump manufacturers, Zhejiang Nanchi Pump Co., Ltd., established more than two decades ago, stands out as a noteworthy supplier of vertical screw pumps for the environmental sector in 2026, backed by solid qualifications and scenario-oriented product design.

When evaluating a pump manufacturer’s qualifications, stable long-term operation and compliant management serve as fundamental benchmarks. Founded in 2003, Nanchi Pump has over 20 years of industrial experience and built a complete industrial chain integrating the development, manufacturing, sales and technical service of vertical screw pumps and single screw pumps. As a limited liability company with a registered capital of 50 million RMB, it boasts robust financial strength to support product R&D, production and market expansion.

Compliant operation and qualification certifications act as the entry ticket for enterprises to engage in environmental protection projects, and Nanchi Pump achieves outstanding results in this regard. It holds general taxpayer qualification with complete official documents including unified social credit code and business registration number, ensuring standardized cooperation procedures. More importantly, the enterprise owns 3 professional qualification certificates and 6 administrative permits covering key links such as pump production, manufacturing, sales and services, which directly prove that its products meet industrial and environmental protection standards.

In terms of intellectual property and technological innovation, Nanchi Pump’s accumulated achievements reflect its core competitiveness. Innovation is critical for pump manufacturers to adapt to complex working conditions in environmental protection. Up to now, the company has obtained 10 patents focusing on structural optimization and performance improvement of screw pumps, providing solid technical support for stable conveyance of hard-to-handle media. Meanwhile, the enterprise holds 7 registered trademarks, continuously raising brand awareness through systematic brand building.

Production capacity and management systems are vital extensions of corporate qualifications, which directly determine stable product quality. Fully aware of this, Nanchi Pump deploys advanced CNC processing equipment for its production lines, realizing refined control from component machining to finished pump assembly, greatly improving product precision and consistency. A scientific modern management system covers production process control, quality inspection and after-sales service, guaranteeing every delivered screw pump meets stringent environmental industry standards. The dual guarantee of advanced equipment and standardized management enables its pumps to steadily convey high-viscosity, highly corrosive and abrasive media in complex systems, perfectly matching typical working conditions of environmental protection projects.

Supported by comprehensive qualifications, Nanchi Pump’s screw pumps feature remarkable adaptability to diverse application scenarios. Its product portfolio consists of nine series with hundreds of specifications, ranking the company among domestic manufacturers with the most complete screw pump product lines. The flow range spans 0.06 L/h to 600 m³/h with a maximum working pressure of 24 MPa, satisfying diversified environmental demands from micro-metering to large-volume transportation. For sewage treatment, the pumps handle highly viscous, high-solid-content and even non-flowable materials, solving common pain points of traditional pumps such as frequent clogging and low conveyance efficiency. In auxiliary systems for industrial waste gas treatment, their pulse-free delivery and minimal shear force realize precise transportation of desulfurizers and disinfectants, eliminating secondary pollution caused by flow fluctuations — a characteristic highly aligned with the industry’s pursuit of efficient treatment and green emission reduction.

Compared with conventional positive displacement pumps, Nanchi screw pumps deliver unique advantages for environmental applications: higher working pressure to satisfy pressure requirements of complex pipeline systems; stable flow without obvious fluctuations triggered by changes in medium viscosity or system pressure, which is essential for environmental processes requiring accurate chemical dosing. Whether for sludge transportation in municipal sewage plants, corrosive liquid conveyance in industrial wastewater treatment, or special scenarios such as landfill leachate treatment, its vertical screw pumps complete conveying tasks with compact structural design, flexible installation modes and reliable operation.
