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 .
