Product Overview

The JYWQ-type automatic-agitation submersible sewage pump is a new environmentally friendly sewage pump developed by Lianlian Pump Industry, a sewage pump manufacturer, which has absorbed advanced foreign technologies and adopted an excellent hydraulic model. Building upon the conventional WQ submersible sewage pump, this pump features unique capabilities in handling solid particles, long-fiber debris, and reducing sediment buildup in sewage pits. Equipped with an automatic agitation device that rotates along with the motor shaft, the pump generates powerful mixing action, suspending settled solids in the tank before drawing them into the impeller for discharge—thus effectively clearing sludge. Additionally, the pump employs a distinctive dual-channel impeller design that is free of blockages, enhancing its ability to handle sewage and waste materials and improving its overall pumping performance. The mechanical seal is a double-face type, permanently immersed in an oil chamber, ensuring the pump operates safely and reliably. A partition divides the base into two separate compartments, allowing the agitation process and water intake to proceed independently without interfering with each other.

Automatic Stirring Submersible Sewage Pump

Automatic agitating sewage pumps are mainly divided into two product categories. The first category is the automatic agitating sewage pump itself, which operates on the principle of adding an agitating disc beneath the impeller. This agitating disc rotates at high speed, automatically suspending the sediment accumulated near the pump. The second category is the new-generation automatic agitating sewage pump—the innovative JYWQ model. This pump relies on three flushing nozzles installed at the bottom of the pump body; the liquid conveyed by the pump itself is used to agitate and suspend the sediment around the pump, thereby achieving the desired agitation effect.

You can also opt for a fully protected, automatic agitating submersible sewage pump equipped with a thermal protector inside the motor. When the motor overheats due to overload, the protector promptly activates to provide protection for both the pump and the motor. A leak-detection probe is installed in the cable chamber; should a leak occur, the probe sends a signal, triggering the control system to protect the pump. An oil-water probe is housed in the oil chamber. If the mechanical seal fails and water enters the oil chamber, the probe will send a signal, prompting the control system to safeguard the pump. This pump is suitable for conveying sewage and waste containing particles and sediments in applications such as chemical industry, petroleum, pharmaceuticals, mining, papermaking, power plants, urban wastewater treatment, municipal engineering, and public utility drainage systems.

Features of the JYWQ Automatic Stirring Submersible Sewage Pump

Model Description for JYWQ Automatic Stirring Submersible Sewage Pump

1. When the JYWQ sewage pump is running, it uses the water pressure generated by the pump itself to automatically stir and mix the settled sludge in the sewage tank, thoroughly preventing the accumulation of debris. No manual cleaning is required, truly achieving the goal of completely removing sediment from the sewage tank.

2. Design of large-flow, anti-clogging hydraulic components featuring a unique double-blade impeller structure that effectively chops and tears fibrous materials and debris, significantly enhancing the pump’s ability to pass through contaminants. The pump can efficiently handle fibrous materials up to five times the diameter of the pump’s inlet and solid particles with diameters approximately 50% of the pump’s inlet diameter.

3. The fluid dynamic seal with an auxiliary impeller structure not only provides auxiliary sealing to protect the mechanical seal but also balances axial forces, thereby extending the service life of the bearing.

4. The mechanical seal employs a tandem double-seal configuration with a new friction pair, and is designed for long-term operation entirely immersed in an oil chamber. The seal material is hard, corrosion-resistant tungsten carbide, which offers exceptional durability and wear resistance, enabling the pump to operate safely and continuously for over 8,000 hours.

5. The JYWQ automatic agitating sewage pump features a compact structure, small size, easy mobility, and simple installation. It doesn’t require a dedicated pump room and can operate simply by being submerged in water, thereby reducing project costs.

6. It can be equipped with a fully automatic safety protection control cabinet that provides protection against pump leakage, electrical leakage, overload, and overheating, thereby enhancing the product’s safety and reliability.

7. Equipped with a float switch, the control cabinet can automatically adjust the pump’s operation—starting and stopping it—based on the desired water level changes, eliminating the need for dedicated personnel to monitor it and making it extremely convenient to use.

8. The motor can be equipped with a water-jacketed external circulation cooling system, enabling the sewage pump to operate at low water levels. This ensures that the electric pump can run safely even in a dry (no-water) condition, allowing it to be used within the designed operating range without overloading the motor, reducing the motor’s starting frequency, and extending its service life.

9. The JYWQ automatic agitating sewage pump can be equipped with various installation methods according to user requirements. It can be fitted with a dual-rail automatic coupling installation system, which greatly simplifies the installation and maintenance of the pump, eliminating the need for personnel to enter the sewage pit.

10. There are two installation methods: fixed automatic coupling installation and mobile free installation, which can meet the needs of different application scenarios.

Do you have centrifugal pumps in stock?

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.

What information should I provide when requesting a quote?

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.

What products do you mainly produce?

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.

Could you help me with the selection?

Certainly! If the water pump model is not selected accurately, there will be big problems. If you choose a smaller one, it won't meet your needs; if you choose a larger one, it will waste electricity and fuel, increasing your costs.

Why is it so slow to get a price quote?

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.
