Usun Model: GBD Cylinder Transfer or Refilling Double Acting Air Gas Pressure Booster Pump

 CZPT Design :GBD   160MM driven  double action large force air pushed fuel

booster for refilling gas cylinder 


CZPT air pushed fuel booster  pumps are ratio products that utilize low force compressed


air driving a bigger diameter piston (spot x pressure) which is linearly linked to a smaller


hydraulic piston/plunger. Utilizing this ratio principal, a increased hydraulic pressure can be created.


CZPT Pump design quantities mirror the pumps nominal force ratio, even though the complex data 


implies actual ratios.  The outlet stall force is easy to set by modifying the air travel stress


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


air pressure, the nominal gas  force can be calculated.

 one.  AIR Generate Part


The air drive part is made up of a light weight piston comprehensive with seals working within an


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


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


(forces as out of the gasoline end).


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


two. GAS  Driven Segment

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 check out valve


opens to the optimum making it possible for gas into the gasoline barrel and on the compression stroke


the inlet verify valve closes the discharge examine valve opens forcing the pumped gasoline


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

 the gas barrel during operation . and the greatest pressures of the pump ,nonetheless the


CZPT PTFE seals are ideal for the two the large vast 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 programs .

CZPT Air pushed gas boosters cycle automatically  as the outlet force 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   

Model assortment for fuel 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 up coming question is wheather you want the booster to stall when an outlet pressure is reached 

If so ,a easy airline stress regulator will suffice ,but keep in mind the flow drops off dramatically 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 1) Maxium outlet strain are at an air pushed pressure of 8 bar or 116 PSI ,for long daily life utilizing

of such pump ,we recommend that air pushed stress must be not much more than eight Bar  .
