Used with the multistage pump, the motor’s wide application ranges in the supply water pressurizing of high building, water delivery in long distance or in the situation when the pressure boost by large pressure equipment is needed, meeting the need of living water supply of residential areas、large architectural complex(like school、army、large factory etc.) and villa-cluster; the motor can be also applied in the refrigeration system of air-conditioner and fire-fighting supercharging of commercial building complex; in pressurizing of waterworks from long distance; or be used to suction clean water from construction site.
Designed to meet international standards as replacement motors for overseas applications and machinery such as pumps, conveyors, fans, crushers, compressors, mixers and more.
Widely applied in metallurgy, chemistry, textile, pharmacy, printing, packing and food industry on the machine or equipment by which speed-regulation is needed, like fan, pump, numerical control machine, machine center, etc.
Grain storage facilities, food processing, textile mill, chemical plant and other applications where hazardous fumes or dust may be present area. However, it does not apply to occasions such as gunpowder or explosives; it is also not suitable for explosion hazards with flammable gases and flammable dust.
Ideal for the coal mine where methane and coal dust may be present (Exd I) and dangerous explosion areas（Ex dⅡAT4、dⅡBT4）in the plant with the class ⅡA ⅡB and temperature T1-T4 flammable gas.
The YFB4 series high-efficiency dust-explosion-proof three-phase asynchronous motors are fully enclosed self-ventilated squirrel-cage three-phase asynchronous motors. This series of motors features small size, light weight, reliable operation, beautiful appearance, high efficiency, large temperature rise margin, low vibration, low noise, high starting torque, and advanced explosion-proof structure.
