Product Applications:

The WQB explosion-proof submersible sewage pump is primarily designed for sewage discharge in industrial environments where explosive mixtures of combustible gases or vapors and air may exist (specifically Class IIB, Temperature Classes T1–T4). It is suitable for use in utility tunnels, municipal engineering projects, building construction, industrial drainage, and sewage treatment facilities, handling wastewater containing solids and short fibers.

Product Overview:

The WQB explosion-proof submersible sewage pump is a new explosion-proof product developed by our company. Its explosion-proof performance complies with standards GB3836.1-2010 (*Explosive atmospheres – Part 1: Equipment – ​​General requirements*) and GB3836.2-2010 (*Explosive atmospheres – Part 2: Equipment protection by flameproof enclosures "d"*). Explosion-proof marking: ExdⅡBT4 Gb. Incorporating the strengths of similar domestic and international products alongside Kaiquan’s extensive experience in submersible sewage pumps, this unit features an optimized design regarding explosion-proof capabilities, hydraulic modeling, and sealing systems. It includes protection against winding overheating and water leakage, offers excellent solids-handling and anti-clogging performance, and is safe, reliable, energy-efficient, and compact, with versatile installation options and convenient maintenance.

Performance and Advantages:

Explosion-proof motor: Suitable for environments requiring flameproof protection as specified by the product's explosion-proof marking;

Smooth flow path, resistant to clogging: Utilizes a channel-type impeller for superior solids handling and anti-clogging performance;

Unique mechanical seal and bearing configuration: Short shaft extension and high rigidity;

Integrated electromechanical design: Pump and motor are directly coupled into a single unit for direct submersion in the medium; easy to disassemble and service, ensuring reliable operation;

Versatile installation options.
