Introduction
Precision Engineering Works, started manufacture of Monoblocks during 1974 in a small factory area of 800 sq. ft. Right from the beginning the stress was on quality The company started growing steadily both horizontally & vertically by adding different products like Submersible Pumps, Single Phase motors & Monoblocks, Flameproof motors and Standard motors. Also increased the volume by adding space machinery etc Presently the manufacturing of motors! pump sets are made in house thus ensuring the quality of the products. This is the sole reason why PEW stands for quality, safety & reliability in the market and has over 500 satisfied customers.
PEW Flameproof of motors suitable for Zone 1 and Zone 2 areas for Gas Group, I, IIA, IIB and IIC are approved by CMRI, CCoE, BIS and DGFAS&L1. |

Efficiency
Motors are offered with efficiency confirming to ‘Eff 2’ of IS: 12615. Motors confirming to ‘Eff 1’ can be offered. The variation in efficiency between 60% to 100% load is nominal which ensures low losses at partial loads.
AMBIENT TEMPERATURE
Motors are suitable for 45’C ambient temperature at an altitude not exceeding 1000m above Mean Sea Level. PEW flameproof motors are suitable for temperature class T1 to T4 as per IS: 6381. Motors upto temperature class T6 can be made available.
DEGREE OF PROTECTION
Motors are provided with IP 55 protection as per IS: 4691. All B5 motors have oil seal at driving end.
INSULATION
Motors are with class ‘F’ insulation with temperature rise of class ‘B’ limits. Motors in Class H can be offered. The slot linings are either provided with double cuffing or edge binding at the slot mouth. To strengthen insulation Surge test is carried out on all windings to ensure their healthiness.
VOLTAGE & FREQUENCY
The motor are suitable for 415+10% V, 50+5%Hz. However motors suitable for operation at 110 to 650V & 25 to 75 Hz can be given.
PRESSURE TESTING
All parts of the Flameproof enclosure are hydraulically tasted for pressure of 15 kg/cm2 as per IS: 2148 : 2004 & IEC 60079-(2001) to ensure that there is no leakage through blowholes or pinholes. |
