About the product

Pneu­mat­ic driv­en liquid pumps gen­er­ate high pres­sures with a min­im­um size. The pumps work accord­ing to the dif­fer­en­tial pis­ton prin­ciple, i.e. nor­mal air pres­sure, usu­ally up to 7 bar, is guided onto a large pis­ton and moves a small hydraul­ic pis­ton. The ratio A (area) x P (pres­sure) of the large pis­ton cor­res­ponds to that of the small pis­ton, apart from low fric­tion losses, just like with pres­sure intens­i­fi­ers. Air pumps offer the fol­low­ing advantages:

• Auto­mat­ic stand­still after reach­ing the set max­im­um pressure
• Easy integ­ra­tion into exist­ing systems
• No energy loss dur­ing long pres­sure hold­ing times
• Due to the com­pressed air drive they are suit­able for use in explo­sion-proof areas
• Coun­ter­act­ing leaks in the system
• Simple activ­a­tion by manu­al or con­trolled valves
