USUN brand Model:ZB04 Similar Haskel EXT420 pneumatic driven refrigerant transfer pump

WHY CHOOSE OUR PUMP?

This brochure introduces pneumatic driven gas/Hydraulic boosters and Complete booster system.

 These gas booster pump offer a flexible and efficient source for delivering high pressure gases.

1.Oxygen or High Purity cleaning : Our booster are noted for their cleaniness and can handle pure gases such as 

oxygen without risk of any contamination.We will use customized lubricants for oxygen and also clean it with ultrosonice cleaner 

2. High Flow rates at High pressure: When High flow rates at high pressure are needed ,the booster 

can charge a receiver to an even higher pressure level ,thus storing a volume of gas aviable for rapid release at a constant

pressure through a pressure reducing valve 

3.Cost savings:Most Industrial gases are commonly delivered at pressure of 2000-2600 Psi in steel cylinders .If the 

Gas is to be used well bellow the supply pressure ,the pressurized supply is easily piped  and controlled to the point of use

with simple valving .However,if the end user requires  the gas to be used at higher pressure then the supply it will have to be

boosted  gas.Gas booster can untilize all the gas from a supply source such as cylinder and boost the gas to whatever  

pressure and flows are required  by the application thus untilizing all the gas volume from the supply source  .

Model :ZB04 single stage similar Haskel ext420 pneumatic refrigerant pump

Application : Nitrogen filling stations ,charging high pressure gas cylinders and receivers  .Gas assisted plastic injection

molding Hydraulic accumulator charging ,Components testing ,Automotive hoses and component gas testing ,biogas charging and pressure tank vessel leakage testing 

Gas Booster Product Configuration

Single Acting,single stage boosters are the smallest amd lightest with pressure up to Maximum 900 Bar .

Double acting,Single stage provides twice the delivery of a single acting ,single stage booster  .

Two stage models are avaible for high gas compression ratios
