Energy efficient electric motors and pumps are a key to increase productivity while reducing the production costs and enhancing profits. Crompton Greaves is a leading company in India renowned for indigenous production of AC and DC motors, motors for hazardous area and for special applications.
Crompton Greaves electric motors, Crompton Greaves flame proof motors stand apart from competition in terms of robust design as per customer requirement and high quality standards. Back pull-out pumps are industry friendly due to their design which is easy to dismantle and reassemble without disconnecting existing piping thus minimizing the process down time. There are a number of back pull out pump dealers; details of whom is available online.
Electric Motors
These motors with their customer specific designs are used in wide range of industrial applications. The AC motors are used in oil and gas platforms, refineries, etc. Crompton Greaves electric motors maintain high design, performance and safety standards. They come in varieties like the high voltage and low voltage motors, energy efficient motors which are 2-6% more efficient than the conventional motors, high voltage motors for hazardous area as per the zone and class, low voltage motors for ignitable atmosphere, etc.
The variable and constant speed DC motors are used in steel, sugar and textile industries. They are also specifically designed for oil well pumps, brake motors, generators, etc.
Flame Proof Motors
Flame proof motors are of two types, Squirrel cage motors with a range of 0.37 – 355 kW and Slip ring motors with a range of 22 – 160 kW. They are used for hazardous environment and comply with strict European and Indian standards such as IS, BS, EN, IEC. The flame proof motors are pressurized to positive pressure. Their over pressure is always monitored and controlled.
They are designed in such a way that they provide relief of external pressure. There is flame gaps created. The escape gases cool along the escape route so that they do not ignite. They have strict specifications of voltage, frequency, insulation ratings, paint, temperature class, etc. They are categorized as per area of usage and have a clear labelling to show the type and level of protection.
The special design flame proof motors work at dual or triple voltage, create low vibrations and noise. They have special bearings and shafts. Some of them operate at multi speeds.
Crompton Greaves flame proof motors have approval from DGMS Dhanbad and BIS licence and also BASEEFA certification from UK.
Back-Pull Out Pumps

They are highly efficient, easy to maintain and have adequate running clearance; they are free of vibrations and available in various configurations. The high precision design eliminates wear and tear. They operate with minimum downtime.
A number of back pull out pump dealers offer pumps for use in refineries, AC plants, power stations, fire-fighting equipment, mines etc.
Summarizing
Motors and pumps are indispensable equipment for several commercial and industrial applications. It is essential to keep their operation and maintenance manuals, MSDS and Training documents handy for easy reference.
