QYF-type pneumatic dredging and sewage discharge pump for mining applications
Traffic: 10-25 m³/h
Head: 20m
Price: 0.32–10.08 ten thousand
The QYF pneumatic dredging pump is an intelligent, highly efficient, and energy-saving pneumatic dredging and sewage discharge pump designed specifically for mining applications. It operates using compressed air—a power source commonly employed in industrial and mining enterprises—and represents a self-developed, innovative product whose technology is at the international forefront. This product is specially designed for pumping materials with high solid content and demonstrates excellent performance in handling high-concentration slurries containing solid particles such as coal rock, slag, wood chips, and metallic objects—making it particularly well-suited for coal mine slurry, oil-based slurry, and concrete mixtures.

Product Parameters
Meaning of the QYF Model Pneumatic Sludge Removal and Wastewater Pump for Mining Applications
Example of pneumatic dredging pump model: QYF20-20 represents a mine-use pneumatic dredging and sewage discharge pump designed for conveying wastewater, waste materials, and sludge; its rated flow rate is 20 m³/h, and its rated head is 20 m.
Product Advantages and Features of the QYF Series Pneumatic Sludge Removal and Wastewater Pump for Mining Applications
Traditional dredging devices typically rely on electric or internal-combustion engines for power, with moving parts in direct contact with the medium being cleaned. This leads to severe wear and tear, high failure rates, and a short service life. Not only does this result in substantial waste of resources—such as equipment repairs and replacements—but it also significantly reduces overall operational efficiency. Moreover, for safety reasons, the application scope of these devices is greatly restricted. In contrast, the dredging and sludge-discharging pump developed by our company uses compressed air—a power source commonly employed in industrial and mining enterprises—as its driving force. When operating under no-load or overload conditions, the unit causes absolutely no damage to the equipment. Furthermore, unlike conventional similar devices, this equipment features no rotating components such as impellers during operation; all moving parts are completely isolated from the conveyed material. As a result, the equipment boasts exceptional solid-passing capability, stable and efficient operation, and dramatically reduced maintenance costs. Additionally, this equipment is highly mobile and easy to maneuver, can handle an extremely wide range of media, and offers multi-purpose functionality—all of which substantially cut down on user costs and labor requirements.
The successful development of this pneumatic dredging pump unit not only fills a domestic equipment gap in certain fields but also offers strong substitutability for existing similar equipment. It provides a new option for dredging equipment in industries such as petroleum, chemical engineering, coal mining, municipal services, and construction, breaking the monopoly held by foreign multinational corporations and boasting a promising market outlook.
·Strong ability to handle contaminants, capable of pumping materials with high solid content and high fluidity.
· Purely pneumatic product, with no electronic components whatsoever, safe and reliable.
·The unit features a compact structure and an ingenious design, enabling automatic operation.
· Moving parts do not come into contact with the material, resulting in zero wear, stable operation, and a long service life.
· No damage to the equipment under no-load or overload conditions; simple maintenance.
·Small in size, lightweight, highly mobile, easy to operate, and suitable for a wide range of applications.
·Low energy consumption, energy-saving and environmentally friendly

Q
What is your typical delivery time?
A
Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。
Q
Do you have centrifugal pumps in stock?
A
Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.
Q
What information should I provide when requesting a quote?
A
Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.
If you are not sure, don't worry, our business managers will assist you in determining this.
Q
What products do you mainly produce?
A
Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.
Q
Why is it so slow to get a price quote?
A
Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
