Key Features
It is a multiplier step up gear box which is compatible with all kinds of our vehicle mounting pumps. We can provide ratios from 1:1 and above as per customer requirement. This unit is perfect for fire engines which have rated torque at low rpm.
Helical gears; made from special alloy steel, carburized, hardened and ground are mounted on an alloy steel shaft and installed in cast iron housing. Water cooling facility is provided for continuous operation. High quality double lip oil seals are provided which offer virtually leak proof operations for extended periods.
Auto Mode - Whenever pump pressure is below 0.8 BAR primer is engaged automatically & when pump pressure is above 0.8 BAR primer is dis-engaged automatically.
Manual Mode - Engage the primer manually but once pump registers 0.8 bar pressure, primer is dis-engaged automatically. Once disengaged, Primer will not engage automatically even if pump pressure is below 0.8 BAR. So pump can be operated at very low pressures without primers being engaged. This mode particularly developed for de-watering application where pump runs at very low pressure for pro-longed time.
