Product Description
Flame proof (FLP) motors
A complete range of crompton greaves flameproof squirrel cage motors for gas group iic is now available for indian industries as an import substitute. The motors are manufactured as per the most stringent requirements for IIC atmosphere. The motors are duly tested at CMRI, Dhanbad. For more details, please contact our nearest branch office / works.
Standard Specifications :
These motors are exclusively designed for safety against accidental ignition or explosions and for continuous flawless operation in explosive or inflammable atmosphere that prevails in petrol and diesel dispensing pumps, chemical factories, petrochemical industries, fertilizer and solvent extraction plants, refineries, bottling plants and paints and varnish works etc.
Construction:
The motors have a heavy-duty seamless steel pipe stator casing with cast iron end-shields designed to withstand internal explosion. All the rotors are dynamically balanced to minimize vibrations. All the components are hydraulically pressure tested. Standard FLP motors has class 'b' insulation. These motors are available with solid foot mounting construction. Flange mounting can be offered on request.
