BQW mine flameproof submersible pump

Product description

BQW mine flameproof submersible pump is specially designed for underground drainage of coal mine with high performance electric pump, in line with MT/T671-2005 "flameproof submersible pump for coal mine" and GB3836.2-2010 "Explosive environment Part 2 Equipment protected by flameproof housing" d "standard, dedicated to the environment with methane or coal dust explosion risk. The electric pump is widely used in coal mine non-mining working surface drainage, tunnel construction drainage, mine water supply and drainage, emergency drainage and other occasions.

Main features:

Pump electric integrated design: the motor and the pump are coaxial, and the pump type or pump type structure is used to ensure efficient and stable operation.

Flameproof structure: with flameproof protection design, suitable for explosive gas environment, to ensure the safe use of dangerous areas such as coal mines.

High reliability: Double mechanical seal is used to prevent leakage and improve service life and reliability.

Widely applicable: voltage range 380V-1140V, head from 4m to 240m, flow up to 2000m³/h, to meet a variety of drainage needs.

Safety guarantee: Class F insulation, IPX8 protection and ExdIMb explosion-proof mark ensure safe operation in complex environments.

Durable and easy maintenance: durable design, simple structure, convenient on-site maintenance, reduce operation and maintenance costs.

BQW mine flameproof submersible pumps perform well in harsh and high-risk environments and are ideal for drainage in coal mines, mines and other explosive hazardous environments.
