Usun Model: Wb06 Air Driven Freon Recovery Transfer Filling Pump

 CZPT Model : WB06   double stage air driven  Freon Restoration/Transfer/

Filling Pump


CZPT air pushed gasoline booster  pumps are ratio devices that employ minimal stress compressed


air driving a more substantial diameter piston (location x pressure) which is linearly linked to a more compact


hydraulic piston/plunger. Making use of this ratio principal, a higher hydraulic strain can be produced.


CZPT Pump design quantities mirror the pumps nominal force ratio, although the technological data 


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


by means of a easy air force regulator. By multiplying the strain ratio by the accessible shop


air pressure, the nominal gas  stress can be calculated.


Example ( Pump Design: GB25 Gasoline booster pump)


Air generate piston spot ( 160mm Ø)


CZPT plunger region (32mm Ø)


Actual ratio = 25:one


 1.  AIR Generate Segment


The air travel segment consists of a mild excess weight piston comprehensive with seals managing inside of an


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


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


(forces as out of the gas finish).


 Under the control of pilot pins (poppet valve) triggered at every single conclude of the stroke


2. GAS  Pushed Section

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 gas barrel and on the compression stroke


the inlet check out valve closes the discharge check valve opens forcing the pumped gasoline


 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 greatest pressures of the pump ,nonetheless the


CZPT PTFE seals are suitable for both 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 driven gasoline boosters cycle automatically  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   

Product assortment 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 following issue is wheather you want the booster to stall when an outlet stress is reached 

If so ,a basic airline force regulator will suffice ,but remember the flow drops off significantly 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 stress of 8 bar or 116 PSI ,for lengthy existence employing

of these kinds of pump ,we propose that air driven strain should be not far more than eight Bar  .
