PRINCIPIO DI FUNZIONAMENTO

OMEGA

 pump 

23:1 

(or 

30:1)

 is a pneumatic pump to be used in the high pressure painting without air (Airless) or for transferring of 

fluids in case of more stations of usage.
OMEGA pump is essentially constituted of an air motor and a structure called «material pumping group» or simply «pumping group».
In the pneumatic motor, compressed air causes the vertical reciprocating movement of the motor piston; this movement is transmitted 
through a connecting rod to the material pumping piston.
So doing the pump sucks the fluid and pushes it to the outlet.
The ratio 23:1 (o 30:1) means that the outlet pressure of fluid is 23 (o 30) times higher than the pump feed air pressure.

Parts of the pump in contact with the material

Pumping group: galvanized carbon steel and cast iron or stainless 

steel AISI 303 and 420B
Sealing balls: stainless steel AISI 420B

Gaskets: PTFE or nitrile or delrin or vulkollan

Other parts of the pump

Support and cylinder for pneumatic motor: aluminium

Covering: sheet FE37

Motor piston and roller pushing mount: cast iron
