Project Introduction

DF10-80X7P Corrosion-Resistant Multistage Pump from a Yunnan Environmental Technology Co., Ltd.

This environmental‑technology company in Yunnan primarily handles the treatment of industrial and mining wastewater, as well as highly corrosive acidic and alkaline effluents. The on‑site operating conditions are complex, placing extremely high demands on the corrosion resistance and operational stability of the pumping equipment. Previously, the plant relied on standard clear‑water pumps that proved poorly suited to these applications; when exposed to wastewater with acidic or alkaline characteristics, the pump bodies rapidly rusted and corroded, leading to frequent issues such as leakage, insufficient pressure, and unstable flow. Equipment failures occurred so often that the system had to be shut down for maintenance every month, delaying wastewater‑treatment schedules and driving up additional costs for spare parts and labor‑intensive operations. Over time, this severely disrupted the project’s normal operation.

To address equipment challenges and meet the demanding conditions of professional environmental protection applications, the company carefully evaluated the performance parameters and real-world reliability of various pump models, ultimately selecting the DF10-80X7P corrosion‑resistant multistage pump. Designed specifically for handling corrosive media in environmental and chemical processes, this pump features core wetted components made of 316L stainless steel, offering exceptional acid–alkali resistance and corrosion durability. It is capable of conveying corrosive liquids across a wide temperature range, fully satisfying the plant’s wastewater‑treatment requirements. Equipped with a seven‑stage impeller configuration, it delivers a standard flow rate of 10 m³/h at a head of 560 m, making it ideally suited for long‑distance, high‑pressure waste‑liquid transfer within the facility.
In addition, this multistage pump features a self‑balancing design that eliminates the need for a conventional balance disc, enabling it to autonomously counteract axial forces. This significantly reduces equipment wear, jamming, and leakage risks, while markedly enhancing operational stability. Following installation, commissioning, and startup, the unit has operated smoothly and reliably throughout its entire service life, effectively preventing leaks and unplanned shutdowns.
