INTENDED USE OF THE ATEX VERSION PUMP
C.4.1
Intended use of the machine
The piston pump series was designed and built by Ragazzini S.r.l. for pumping fragile,
abrasive, corrosive and alimentary fluids compatibly with the materials of which the
pump itself is made and wherever the transfer of large masses of liquids is required.
Based on the characteristics of the product to be transferred, the machine is equipped
with the most suitable seals as indicated in the paragraph J.4
The machine must only be used on flat surfaces. In the version supplied with wheeled
frame, turn the front wheels with respect to the axis of the machine as a braking
system.
To ensure the correct use of the pump, always check:
The presence of lubricant, where necessary (crankcase, variator, etc.).
That the pumped fluid is always compatible with the construction materials of the pump itself.
That in the processed fluid there are not and there may not be solid parts or foreign bodies of large
dimensions or such as to cause damage or compromise safety.
That there is no oxidized steel nor ferromagnetic parts, even small ones.
That there are no conditions that could cause motor overload.
The correct grounding of the pump, the motor or other components connected to it.
Environmental limits of the machine:
Ambient temperature: > 0°C and ≤40°C. For ambient temperatures ≥-20°C and ≤0°C, contact
Ragazzini Technical Service.
Work environment: indoor or outdoor with protection from sunlight and bad weather, classified as
ATEX zone II 2G h IIB T4 Gb - II 2D h IIIB T = 135°C Db.
Lighting: The area of installation must be sufficiently lit (minimum 200 lux).
ANY OTHER USE DIFFERENT FROM THE ONE DESCRIBED IS NOT ALLOWED BY THE
MANUFACTURER.
C.4.2
Prohibited use.
The equipment must not be used:
For operations other than those described under paragraph C.4.1
“Intended use of the machine”.
In places with temperatures outside the range between -20°C and +40°C.
Near systems generating stray electrical currents.
In open environments or in closed places without a lightning protection system.
With direct exposition to sunlight.
Without liquid to be pumped (dry running) for more than 10 minutes.
Restrictions on the use of the equipment:
It is forbidden to:
Use the equipment in a configuration other than the one envisaged by the manufacturer.
Use the equipment in areas classified as Zone 0-20.
Use the equipment in areas containing gases whose flammability temperature is below 135°C.
Use the machine in areas subject to the presence of IIC classified gases.
Pump products with a temperature above 40°C; exceeding this limit does not allow compliance with
the temperature class.
Integrate other systems and/or equipment not foreseen by the manufacturer in the design.
Remove components and parts of the machine.
Use the pump in case of product/pumped fluid leaks.
