General Information for Air driven hydraulic pumps

USUN air driven liquid  pumps are ratio devices that utilize low pressure compressed

air driving a larger diameter piston (area x pressure) which is linearly connected to a smaller

hydraulic piston/plunger. Using this ratio principal, a higher hydraulic pressure can be generated.

Usun Pump model numbers reflect the pumps nominal pressure ratio, while the technical data 

indicates exact ratios.  The outlet stall pressure is easy to set by adjusting the air drive pressure

through a simple air pressure regulator. 

Typical applications for air driven Liquid pumps

Key features

1. Realiable ,Easy to Maintain ,compact and robust

2. No heat,flame or spark risk

3. Infinitely variable output pressure and flow capability 

4. Air driven Models do not require electrical connection ,easy to apply automatic controls

5. Wide range of models and controls and options 

6.Seals system designed for long working life,No airline lubricated required

7. Wide range of standard and customized liquid pump systems

Main technical data  

Remark 1) Maxium outlet pressure are at an air driven pressure of 8 bar or 116 PSI ,for long life using

of such pump ,we suggest that air driven pressure should be not more than 8 Bar  .
