GENERAL TECHNICAL FEATURES OF HIGH PRESSURE PUMPS
The range of A/R plunger pumps is used with flows from 8 to 40 Litres/min.
(2.1 to 11 gpm) and with maximum pressures of 250 bar ( 3600 PSI). Each
type of pump is designed and developed to work at the performance
indicated on the pumps
nameplate.
If, infact, the flows depends upon:
a) the diameter of the piston,
b) the stroke of the piston,
c) the number of pistons,
d) the number of stokes for minute;
the pressure generated by the pump depends upon the choice of the nozzle,
IT IS THEREFORE A NECESSITY THAT THE PRESSURE AND THE R.P.M. REMAIN
WITHIN
THE MAXIMUM VALUES INDICATED.
The pumps are made of special materials, which are resistant to corrosion
such as stainless steel, ceramic compounds, brass and aluminium alloys
with protective treatments.
Ceramic pistons, moving parts in an oil bath, oil level dipstick and oil level
window for quick check. High quality packings with easy access, making
for rapid maintenance, as well as inspection friendly suction/outlet valves.
The hydraulics are separated from the crank mechanism with a recovery
and recycling system for leaks, thereby avoiding the pollution of the
lubricating oil.
ATTENTION
SAFETY STANDARDS
• Do not spray persons or animals with a high pressure jet.
• If driven by an electric motor, the machine must be equipped with a
protective circuit which guarantees the operator's safety from high
voltage.
•If driven by a gas engine, do not use the unit indoors. Discharge gases
include carbon monocide an odourless but lethal gas.
