Product Description

BQ series mining flame-proof submersible electric pumps are the latest large-scale pumping equipment designed for extreme environments. Developed with extensive professional rescue and drainage expertise, this equipment is engineered for high-performance mine recovery and disaster relief. This product features a double or single suction multistage centrifugal pump integrated with a water-filled, high-pressure submersible three-phase asynchronous motor.

🔹 Working Conditions

Voltage: 6000V or 10000V
Medium PH: 4-10
Water Temp: ≤50ºC
Solid Content: ≤10%
Depth: Submergence depth up to 700m

The pump is driven by a specialized wet stator submersible motor. Unlike standard IP68 motors, the wet stator housing is filled with water, utilizing special windings with IPX8 protection, allowing for unrestricted submergence depth and superior cooling efficiency in harsh mining conditions.

Frequently Asked Questions

What types of pumps do you specialize in?

We specialize in mining submersible pumps, specifically high-power, flame-proof, and high-pressure drainage systems designed for mine recovery and industrial applications.

Do you offer customization for specific mining environments?

Yes, we provide customized services for high-pressure needs, large flow requirements, and special installation orientations (vertical, horizontal, or inclined) based on your site conditions.

What is the standard lead time for production?

The typical production time is approximately 30 working days, depending on the order quantity and specific customization requirements.

How are the pumps protected during shipping?

We use export-standard wooden cases that are reinforced to protect the equipment from physical damage and environmental factors during sea or air freight.

What are your quality certifications?

Our products are manufactured under ISO9001, ISO14001, and CE standards, and carry necessary flame-proof certifications for hazardous mining environments.

What are the main advantages of a wet stator motor?

The wet stator motor provides superior heat dissipation as the stator is submerged in water, allowing it to operate at much greater depths than standard submersible motors without overheating.
