Usun Model: GB02 8-16 Bar Pneumatic Driven Hydrogen Gas Booster Pump for Cylinder Refilling

 CZPT Design :GB02   160MM pushed pneumatic driven  hydrogen gasoline booster
pump for cylinder refilling  


CZPT air pushed gasoline booster  pumps are ratio products that employ reduced strain compressed


air driving a more substantial diameter piston (spot x pressure) which is linearly connected to a smaller


hydraulic piston/plunger. Employing this ratio principal, a larger hydraulic stress can be generated.


CZPT Pump product quantities reflect the pumps nominal force ratio, even though the complex data 


indicates precise ratios.  The outlet stall force is straightforward to set by changing the air generate strain


via a easy air strain regulator. By multiplying the stress ratio by the available shop


air pressure, the nominal gas  pressure can be calculated.


Case in point ( Pump Design: GB25 Fuel booster pump)


Air drive piston location ( 160mm Ø)


CZPT plunger location (32mm Ø)


Actual ratio = 25:1


 one.  AIR Push Segment


The air travel section is composed of a light excess weight piston complete with seals running within an


aluminum barrel. The diameter of the air piston is 160mm. When compressed air is provided to


the pump the air pushes the air piston down on a compression stroke


(forces as out of the gasoline stop).


 Under the control of pilot pins (poppet valve) brought on at each and every stop of the stroke


two. GAS  Pushed Part

The gas section of a CZPT air driven gas booster consisit of 4 main pieces  


,the gas barrel  ,the piston the check valves  and the main high pressure seals  .


The gaspiston is directly linked to the air piston and it is housedinside the gas barrel 


and its movements up and down creates the gas flow into and out of the booster through


 the check valves . The check valves are psring loaded and on the suction stroke .the inlet examine valve


opens to the greatest allowing gasoline into the gasoline barrel and on the compression stroke


the inlet verify valve closes the discharge verify valve opens forcing the pumped gas


 into the approach  .The main high pressure seals is located on the gas piston and they seal agaist

 the gas barrel during operation . and the maximum pressures of the pump ,however the


CZPT PTFE seals are suitable for equally the large majority of gases encountered .


Other materials of construction  can be supplied to meet more aggresive services  


.The CZPT  serials of booster are not suitable for underground coal mine applications  .


CZPT DO CZPT models of  air pushed gasoline boosters  that are not suitable for underground

coal mine applications .

CZPT Air driven fuel boosters cycle immediately  as the outlet stress increass the


resistance also increases and the cycle rate decreases until the pump stops automatically 


when the out put pressure forces are equal .This is refered to as the stall condition  .


The pump will restart with a slight drop in the outllet pressure or an increase in the  air driven pressure 

Booster performance can be affected by a number of conditions ,


such as freezing of the exhaust muffler   or pilot valves ( Which is caused by moisture in


 air lines  ),inadequate  inlet air line sizes and dirty filers .When  operating the boosters 


on a contunuous basis  ,we recommend you use a maximum cycle rate of 50-60 cycles per minute .


This will both  increase service intervals  and assist in preventing ice forming at the exhaust  .


An air supply dryer will also assist in reducing icing up  .


CZPT Gas boosters have a 120mm stroke thus reducing cycle rates at any given flow 


and pressure as compared with most other brands  . This lower repsective cycle rate res


ults in a reduction in freeze-up  condition  .


To abtain best overall performance  ,do not reduce the indicated port size and consult

CZPT for flow conditions not shown in charts   

Product variety for gas booster  

 It is very important to remember that the performance of any air driven device is very dependent 

on the air supply conditions .Restrictions in the air supply can be caused by using a too small air compressor or 

airlines  .The FLOW CHARTS SHOWN in the technical data sheet are based on good conditions  .

 so please do not “design  to the line ”  allow for losses and inefficiencies  

The next question is wheather you want the booster to stall when an outlet stress is reached 

If so ,a basic airline pressure regulator will suffice ,but remember the circulation drops off substantially as the 

booster reaches a stall condition  .

 If you require flow at a particular pressure ,then you need read the flow cahrts carefully and conservatively  

 If you need the pump to stop at a certain pressure ,prior to stall ,then an air pilor switches needs to be installed  .

 Remark one) Maxium outlet stress are at an air pushed strain of 8 bar or 116 PSI ,for lengthy life utilizing

of this kind of pump ,we recommend that air driven strain need to be not much more than eight Bar  .
