Application
This pump is ideal for diverse applications including buildings, hospitals, residential areas, municipal projects, roadworks, factories, and small-scale sewage treatments.
Versatile in handling pumped liquids, it efficiently processes rainwater and wastewater containing solids and long fabrics.

Working Conditions
1. Power Supply: Compatible with 50Hz, 3-phase, 380V systems.
2. Medium Temperature: Operates effectively below 40ºC , with a pH range of 4-10. It can handle medium densities of less than 1200 kg/m³ and a solid-to-liquid ratio below 2%.
3. Installation Requirements: The liquid level must adhere to specifications outlined in the installation drawing.
4. Limitations: Not recommended for strongly corrosive liquids or solids.
5. Solid Size: Solids should not exceed the maximum allowable diameter.

Structure
1. Precision Engineering: Carefully matched pump body and impeller ensure efficient flow and high-performance, preventing overload with a stable rotation and minimal vibration.
2. Motor Excellence: Featuring a specially crafted submersible motor with IPX8 protection and Class F insulation, it promises outstanding cooling performance and a prolonged operational lifespan.
3. Efficient Cooling System: The motor shell dissipates heat effectively, allowing safe operation when the medium covers at least half of the stator shell.
4. Robust Shaft Seal: Equipped with two or three mechanical seals in series, providing comprehensive separation between the medium, oil chamber, and motor.
5. Protected Oil Chamber: Contains suitable oil to prevent leakage and provide lubrication, cooling, and heat removal. The two mechanical seals offer stable operation and contribute to the longevity of the bottom bearing and motor.
6. Bearing Support: The bottom bearing setup provides stable support for the shaft, tailored to handle radial and axial forces, ensuring consistent performance and a long service life.
7. Cable and Mechanical Seal:
1. Featuring a soft rubber cable resistant to sewage, designed to withstand ambient temperatures up to 40°C and full-load motor conditions. Under optimal conditions, pumps can achieve extended operational durations.
2. Experience superior reliability with our advanced sealing system, ingeniously designed between the cable's rubber cover and the motor. This innovative feature is expertly crafted to thwart any medium leakage into the motor cabinet, ensuring seamless operation at all times.
3. Our cables are encased in robust rubber vulcanization, providing an additional layer of protection. Even if the rubber cover is compromised, our system continues to prevent any medium from leaking into the motor cabinet, safeguarding your investment with precision engineering.
8. Motor Shell: Composed of a sturdy base, bearing seat, and motor cover, our motor shell is fortified with expertly placed seals at every joint. Rigorous water pressure testing is conducted on each pump to guarantee an impenetrable seal, offering you unmatched durability and peace of mind.
9. Safe Protection in Pump (Earthed Professional Power Supply Controlled Cabinet): Our cutting-edge protection system ensures unparalleled safety and reliability, with an earthed professional power supply controlled cabinet meticulously designed for optimal performance.
1. Oil Water Detector: Installed in the oil chamber with precision, this detector vigilantly monitors for leakage of the first mechanical seal in the medium. Should the medium infiltrate the oil chamber, timely alerts ensure you're informed, allowing you to take swift action.
2. Water In Detector: Strategically placed in the motor cabinet, this detector identifies leaks in the second mechanical seal. When oil or oil-water mixtures encroach the motor space, the detector promptly triggers an alarm, halting pump operation to prevent damage.
3. Thermal Part: Situated within the motor stator windings, this component vigilantly monitors potential overloads. If prolonged overloads or other factors cause a rise in winding temperature, the thermal part activates an alert and stops the pump, protecting your equipment from harm.
10. Outer Control System: Experience seamless integration and control with our sophisticated outer control system, designed for effortless operation and enhanced protection of your pump.
1. For optimal performance, users should employ a professional control cabinet to manage and safeguard the pump. If opting for a personal control cabinet, please contact us for expert guidance on installing the protection controller, ensuring your system's longevity.
2. Special Hand Lift for Easy Movement: To ensure the integrity of your pump, never move it by the cable, as this may compromise the seal and lead to leakage. Additionally, avoid fixing the cable on the hand lift for movement, preserving the pump's flawless operation.
3. Performance Curve and Main Technical Data: The performance curve outlines the optimal operating range for the pump. It's crucial to maintain shaft power within the rated motor power range as changes in the medium occur. Overloading may result in motor damage. Stay informed to maintain efficiency and avoid motor burn-out.
