â… ï¼ŽProduct Introduction
The ZPG-L Automatic Backwashing Water Filter is a high-performance filtration equipment designed to address the inherent shortcomings of traditional filter products. Traditional filters are plagued by issues such as low pollution capacity, susceptibility to clogging by dirt and debris, the need to disassemble the filter element for cleaning, and the inability to monitor filter status in real-time. In contrast, the ZPG-L Automatic Backwashing Water Filter integrates raw water filtration and automatic filter cleaning & drainage functions seamlessly.
A key advantage of this filter is that its cleaning system enables uninterrupted water supply during the cleaning process, ensuring stable water supply for subsequent production and use. It is also equipped with a complete monitoring system that can real-time track the working status of the equipment, achieving a high degree of automation and reducing manual intervention. The filter features flexible installation options and can be mounted vertically, horizontally, or upside down according to on-site installation conditions and space requirements.
Due to its excellent performance and wide adaptability, the ZPG-L Automatic Backwashing Water Filter is widely applicable in water treatment scenarios across multiple industries, including industry, agriculture, municipal engineering, power generation, electronics, medicine, food processing, printing and dyeing, steel, metallurgy, and papermaking. It effectively removes particulate impurities in water, purifies water quality, and provides reliable water source guarantee for various production and living activities.
Ⅱ．Product Features
-
Strong Pollution Capacity & Anti-Clogging Performance: The filter adopts advanced structural design and high-quality filter materials, which can effectively intercept and accumulate particulate impurities in water. Compared with traditional filters, it has a larger pollution-holding capacity, reducing the frequency of clogging and extending the stable operation cycle.
-
Automatic Backwashing & Uninterrupted Water Supply: The filter can automatically trigger the backwashing process when the pressure difference reaches a preset value. During the cleaning process, the diversion butterfly plate and sewage valve cooperate with each other reasonably, realizing the automatic cleaning and discharge of impurities without stopping the water supply. This ensures the continuity of water supply and avoids production losses caused by shutdown for cleaning.
-
Real-Time Monitoring & High Automation Degree: Equipped with a professional monitoring system, it can accurately reflect the working status of the filter (such as pressure difference, operation status, etc.) in real-time. The whole process of backwashing, cleaning and drainage is automatically completed without manual operation, which reduces the labor intensity and improves the operation efficiency.
-
Flexible Installation Methods: It supports multiple installation methods such as vertical, horizontal and inverted, and can be flexibly installed according to the actual space and pipeline layout of the project. For ZPG-L type (right-angle automatic sewage discharge filter), it can be installed directly on the elbow; for ZPG-1 type, it can be installed horizontally or vertically (when installed vertically, the water flow direction should be top-down), which has strong adaptability to the site.
-
Wide Range of Material Selection & Strong Corrosion Resistance: The shell can be made of carbon steel, stainless steel and other materials, and the filter material is high-quality stainless steel. The gasket can be selected from PTFE, metal winding, nitrile rubber and other materials according to different working conditions. It has strong corrosion resistance and can adapt to different water quality environments (such as tap water, industrial wastewater, etc.).
-
Protect Subsequent Equipment & Extend Service Life: By effectively removing impurities in water, it can prevent the wear, clogging and corrosion of subsequent equipment (such as pumps, valves, heat exchangers, etc.), reduce the failure rate of equipment, and extend the service life of the entire water supply system. Especially when matching with safe pump valves, the protective effect is more significant.
-
Wide Filtration Precision Range: The filtration precision can be adjusted between 10 mesh and 500 mesh according to the actual water quality requirements, which can meet the different filtration needs of various industries (such as high-precision filtration requirements in electronics and medicine industries, and conventional filtration requirements in agriculture and municipal engineering).
