For manufacturing enterprises, technological innovation is the core driver of sustained competitiveness. Nanchi Pump places R&D investment at a strategic priority, carries out technical research targeting industry pain points and forms product advantages centered on patented technologies.

Aiming at the universal problem of accumulation and blockage of traditional screw pumps during straw conveyance, the company’s R&D team completed long-term research and repeated trials to develop patented dedicated straw screw pump technology, delivering a practical solution to this long-standing industrial pain point. In terms of technical principles, the patent optimizes and upgrades the core structure of screw pumps, redesigning the connecting structure of end cover, pump body and feeding chamber to create smoother flow paths for straw during conveyance and drastically reduce material retention and accumulation at joints. Meanwhile, the shape and pitch of the screw are specially modified according to the physical properties of straw to boost the pump’s pushing capacity and material adaptability. The equipment achieves stable and efficient conveyance for hard corn straw, tough wheat straw and mixed crushed straw with impurities alike.

Compared with conventional equipment, Nanchi’s dedicated straw screw pumps deliver remarkable improvements in operational stability and efficiency. Structural optimization drastically reduces failure rates and extends maintenance cycles, cutting customers’ downtime losses and maintenance costs. Meanwhile, enhanced transport efficiency better matches the operational demands of biogas production in biogas plants, providing robust equipment support to raise overall production efficiency. Additionally, the product features low energy consumption and easy operation, fully aligning with the development philosophy of green and efficient modern agriculture.

Beyond technological breakthroughs in straw conveying pumps for biogas plants, Nanchi Pump has in-depth layout and technical reserves for related sectors including fruit & vegetable crushing transfer pumps and high-viscosity material transfer pumps. Its fruit and vegetable crushing conveying pumps adopt a gentle conveyance design tailored to the high moisture and fragile nature of fruit and vegetable materials, minimizing material damage while guaranteeing transport efficiency. They are widely applicable to biogas production from crushed vegetables, deep fruit and vegetable processing, juice production and resource utilization of fruit and vegetable waste, and have won wide market recognition relying on technical strengths. Up to now, the company holds multiple pump patents covering diverse application scenarios, forming diversified technical reserves and a comprehensive product portfolio to meet personalized demands from various industries and customers.

Nanchi Pump fully recognizes that product quality is the foundation of survival for industrial manufacturers, while a comprehensive service system extends the value of cooperation. For quality control, the enterprise has built a full-process quality management system covering raw material procurement, production processing, finished product inspection and outbound delivery.
