3kw 2.2hp 52m³/h 7m Explosion-Proof Submersible Sump Pumps submersible slurry pump Low Head High Discharge Pump For Sewage Water
The WQB52-7-3 is an efficient submersible pump designed to meet moderate flow requirements, suitable for a variety of applications such as light industrial drainage, wastewater treatment, and agricultural irrigation. This pump offers a maximum flow rate of 52 cubic meters per hour (m³/h) with a head reaching up to 7 meters, powered by a robust 3 kW motor, ensuring stability and efficiency when handling fluids containing suspended particles. The overcurrent components can made from high-quality materials like 304 or 316 stainless steel, providing excellent corrosion resistance, making it ideal for long-term reliable operation even in environments with chemical substances.
The WQB52-7-3 features an optimized hydraulic design that effectively reduces the risk of clogging and enhances overall efficiency. It also comes equipped with high-performance mechanical seals to ensure leak-free operation, thereby reducing maintenance frequency and extending the lifespan of the pump. To further enhance reliability, users can opt for an intelligent monitoring system that provides real-time data on critical parameters such as temperature, pressure, and vibration. This enables preventive maintenance, minimizing downtime due to unexpected failures. The compact design facilitates easy installation and maintenance, making it particularly suitable for use in space-constrained settings.

When the explosive gas mixture in the flame-proof submersible sewage pump motor explodes, flame-proof shell shall not be damaged and the internal flame will not cause further explosion. The parts of explosive shell are tested by water pressure tests according to GB3836.2-2000 standard to ensure maximum internal pressure explosion.
The flame-proof submersible sewage pump is marked as ExdIIBT4/ExdIICT4, which is suitable for factory IIB/IIC class, temperature group is T1-T4 of combustible gas and explosive mixture of steam and air.The maximum surface temperature must adhere to the specifications outlined in the following list:
| Temperature Group | T1 | T2 | T3 | T4 |
| Maximum surface temperature | 450 | 300 | 200 | 135 |
- The flow parts adopt QBQ surface treatment process, which has excellent wear and corrosion resistance.
- The thickened impeller, pump body, and pump cover effectively extend the service life of the components.
- Suitable for long-term use in environments with corrosive liquids and abrasive particles (such as sediments and gravel).
- The bottom inlet and bottom outlet design ensures strong clogging resistance and high flow capacity, making it suitable for a wider range of applications.
- Simple strcuture, lightweight, easy to install and maintain.
- The pump equipped with cooling jacket, which has high heat dissipation efficiency,could not fully submerged in the medium.
