Changyu UHB-ZKD Series Slurry Pumps Delivered to a Steel Plant for Flue Gas Desulfurization Process - ChangYu Pump

Project Overview

Recently, Changyu Pump Valve Manufacturing Co., Ltd. successfully supplied multiple UHB-ZKD series slurry pumps to a major steel mill for its flue gas desulfurization (FGD) system. This project aims to reduce sulfur dioxide emissions generated during production and enhance the company’s environmental performance. The UHB-ZKD series slurry pumps have earned high recognition from the customer due to their outstanding corrosion resistance, wear resistance, and operational stability.

Customer Requirements

During steel production, significant amounts of sulfur-containing waste gases are generated. To reduce air pollution, steel plants must employ flue gas desulfurization processes. In this process, limestone slurry needs to be efficiently transported to the desulfurization tower, which places high demands on the pump’s corrosion resistance, wear resistance, and operational stability. The customer had the following key requirements:

1. High corrosion resistance: The medium used in FGD is highly corrosive, requiring pump materials that can withstand long-term exposure to harsh acidic and alkaline environments.
2. High wear resistance: The limestone slurry contains solid particles, which can cause significant wear on the equipment. The customer required pumps with exceptional wear resistance.
3. Stable performance: The pumps must run continuously for long periods without failure, as any malfunction could impact the entire desulfurization system.

Solution

In response to the customer’s needs, our technical team recommended the UHB-ZKD series slurry pumps, which offer the following advantages:

1. Corrosion-resistant materials: The UHB-ZKD series pumps are made from high-strength corrosion-resistant alloy materials, making them ideal for handling highly corrosive media and ensuring stable operation in demanding environments.
2. High-efficiency wear-resistant design: The pump’s flow path and impeller materials are specifically chosen to address the wear caused by solid particles in the slurry, significantly extending the pump’s service life.
3. High stability and low maintenance: The pump has undergone multiple technical improvements, ensuring long-term, smooth operation even in harsh working conditions, with simple and low-cost maintenance.

Technical Advantages:

Corrosion-Resistant Construction: Pump body utilizes high-strength corrosion-resistant materials, suitable for transporting acidic and alkaline media.

Enhanced Wear Resistance: Optimized impeller and flow path structure effectively reduces slurry abrasion, extending service life.

High Efficiency & Low Maintenance: Smooth operation with minimal vibration, simplified maintenance, and reduced operating costs.

Customer Feedback

The steel plant expressed high satisfaction with the performance of the UHB-ZKD series slurry pumps. Since installation, the pumps have run smoothly, significantly improving the efficiency of the FGD system while reducing equipment failure rates. After several months of continuous operation, the customer reported that the pumps required less maintenance than anticipated, contributing to lower operational costs and enhancing the environmental performance of their production line.
