Air-Driven Liquid Pumps & Intensifiers

Air-driven liquid pumps and pneumatic pressure intensifiers convert simple air pressure into high and ultra high liquid pressure by using a large-area piston on the air side to move a small-area plunger, compressing the liquid to very high pressures – up to 4,140 bar (60,000 psi) as standard, and as high as 14,000 bar on special request.

Actuated by compressed air (maximum 7 or 10 bar), the pressure delivered on the liquid side can be adjusted with a manual precision regulator or an automatic proportional pressure regulating valve. These pumps are suitable for explosion-proof systems (explosion-proof operation), as they need no electric power supply.

Hydraulic-powered pressure intensifiers can be used for liquids and gases in continuous or discontinuous operation and are driven by a hydraulic power unit. They convert hydraulic pressure (usually 210 bar or 350 bar) to high and ultra high liquid pressure, and the outlet pressure is changed simply by varying the hydraulic pressure. With flexible design we can deliver intensifiers with single or double high pressure heads, up to 14,000 bar and with volume displacement up to 30 L; one or more units can be powered from the same hydraulic unit.

The structure of these intensifiers allows reliable operation and long lifetime, with simple maintenance and easy service.
