CONTROL UNITS - MG SERIES
The use of a special overgear provided with a spline shaft, has made it possible to couple the normal angle driving gears to the power takeoff of the tractors normalized at 540 or 1000 rpm, through the cardan shaft. Like the RA drive units, these are also provided with a water circulation oil cooling system which, in this series, is extended to structure of the overgear case. This system keeps the whole unit at the right operating temperature, also in continuous working conditions and with very high ambient temperatures.
THE PUMPS
Made up of a series of modular stages, they are provided with a fi tting for the upper pipe and normally with a foot valve flanged to a suction rose in galvanized steel which prevents the foreign matter from getting into the suction system. The pump bodies and the valve body are made in fine- grained gray iron, the impellers with semiaxial flow and dynamically balanced, are available in cast iron or in bronze on reques.; the pump shaft guided by wearproof rubber bearings, is in hard-chromed carbon steel or in stainless steel on request.
THE LINE SHAFT
It is formed by a rising steel pipe with double flanged trunks whose standard length is 3 Mt. It makes it possible for the pump to be positioned in depth and to convey water. Driving is performed by rods guided on each end by wearproof rubber bearings which keep a perfect alignment of the driving axle in all installation depth. Near each rubber bearing, the rods are protected by hard-chromed wear brass bushes. The threaded connection sleeves and the rods are made in carbon steel or in stainless steel on request. The rubber bearings are arranged in the middle of a cast iron support placed between the pipe flanges.
