Usun Model: GB02 Maximum 16 Bar Air Driven Gas Booster Pump for Vacuum Refilling

 CZPT Product :GB02   160MM driven pneumatic driven organic Gasoline Booster Pump

for Charging Cylinders


CZPT air pushed fuel booster  pumps are ratio units that utilize lower pressure compressed


air driving a more substantial diameter piston (region x strain) which is linearly linked to a smaller


hydraulic piston/plunger. Utilizing this ratio principal, a greater hydraulic force can be created.


CZPT Pump model numbers reflect the pumps nominal force ratio, while the technical data 


implies exact ratios.  The outlet stall pressure is effortless to set by modifying the air drive strain


via a straightforward air stress regulator. By multiplying the pressure ratio by the obtainable store


air pressure, the nominal gas  pressure can be calculated.

CZPT plunger region (32mm Ø)


Genuine ratio = 25:1


 one.  AIR Drive Part


The air drive area is composed of a mild bodyweight piston comprehensive with seals operating 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 fuel finish).


 Under the control of pilot pins (poppet valve) induced at every finish of the stroke


2. GAS  Driven Area

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 verify valve


opens to the maximum allowing fuel into the gas barrel and on the compression stroke


the inlet check valve closes the discharge check valve opens forcing the pumped fuel


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

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


CZPT PTFE seals are appropriate for both the 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 applications .

CZPT Air driven gas boosters cycle immediately  as the outlet pressure 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 choice 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 subsequent issue is wheather you want the booster to stall when an outlet force is reached 

If so ,a simple 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 one) Maxium outlet force are at an air driven strain of eight bar or 116 PSI ,for lengthy lifestyle using

of this kind of pump ,we suggest that air pushed strain must be not far more than 8 Bar  .
