Usun Model: GB Oil Free Air Driven Gas Booster Pump for Refilling Gas Cylinder

 CZPT Model :GB  Oil free of charge air pushed fuel booster pump for refilling gasoline cylinder 


CZPT air driven fuel booster  pumps are ratio products that employ minimal stress compressed


air driving a larger diameter piston (location x strain) which is linearly connected to a smaller sized


hydraulic piston/plunger. Using this ratio principal, a increased hydraulic strain can be produced.


CZPT Pump design figures replicate the pumps nominal stress ratio, while the specialized data 


suggests actual ratios.  The outlet stall pressure is simple to set by changing the air push stress


by way of a basic air force regulator. By multiplying the stress ratio by the obtainable store


air pressure, the nominal gas  pressure can be calculated.

 1.  AIR Push Segment


The air drive section is composed of a light-weight excess weight piston complete with seals operating inside of 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 finish).


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


2. 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 check valve


opens to the highest permitting gas into the gas barrel and on the compression stroke


the inlet check valve closes the discharge examine valve opens forcing the pumped gas


 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 ,nevertheless the


CZPT PTFE seals are appropriate for the two the large bulk 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  .

coal mine applications .

CZPT Air pushed gas boosters cycle automatically  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

 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 following issue is wheather you want the booster to stall when an outlet pressure is reached 

If so ,a simple airline force regulator will suffice ,but keep in mind the circulation drops off drastically 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  .

Crucial characteristics

one. Realiable ,Effortless to Maintain ,compact and robust

 Remark one) Maxium outlet pressure are at an air pushed stress of 8 bar or 116 PSI ,for extended life using

of such pump ,we suggest that air pushed strain must be not more than eight Bar  .
