INTRODUCTORY REMARKS
Pumps transform the mechanical energy the prime mover
generates into hydraulic energy. The transmission from one
part to the other is usually performed by their respective
shafts connected via a flexible drive coupling that offsets
misalignment; a gear over or reduction unit must often be
interposed, especially in the case of endothermic motors. With
a few exceptions, standard revolution speeds for three-phase
electric motors are compatible with the direct connection to
the pump; speed is usually 1400 or 2800 rpm, but if the system
is equipped with an electronic device known as ‘inverter’, the
number of revolutions can be adjusted from the minimum to
the maximum limit.
As we stated in the introduction, it is important to note that,
with a few exceptions, the revolution speed of the prime
mover/pump, connected directly or via an adapter, has to be
constant in oil hydraulics: as a result, flow, which depends

Manufacturers specify in the ratingplate the minimum and
maximum viscosity the pump can endure, that is the tolerable
viscosity range beyond which the parameters of components
are no longer guaranteed, because it is difficult to determine
the exact optimum viscosity (it is affected by many factors) and
viscosity limits must be known. For instance, in a pump with a
stated range of 16-200 cSt, at start viscosity at any environmental
temperature must not exceed 70 cSt and it must be at least 30
mm2/s with exceptional running at high temperatures.
These viscosity limits are often unsuitable in some operational
conditions, especially for self-propelled machines. A snowplough

that is small so as to fit to a farm tractor exceeds the maximum
operational temperature quickly. Some special devices, like heat
exchangers placed in theoutlet hose or tank preheating electrical
resistances, reduce fluid temperature. In addition, special vane
pumps are available on the market: they can be started at very
high fluid viscosity (500-600 cSt at start) and their revolution
brings the oil to the working temperature, although it cannot
guarantee the immediate pressurisation of the vehicle.
