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 

“SEALS”. 

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.
