CZPT Design :GB02 160MM pushed pneumatic driven hydrogen gasoline booster
pump for cylinder refilling
CZPT air pushed gasoline booster pumps are ratio products that employ reduced strain compressed
air driving a more substantial diameter piston (spot x pressure) which is linearly connected to a smaller
hydraulic piston/plunger. Employing this ratio principal, a larger hydraulic stress can be generated.
CZPT Pump product quantities reflect the pumps nominal force ratio, even though the complex data
indicates precise ratios. The outlet stall force is straightforward to set by changing the air generate strain
via a easy air strain regulator. By multiplying the stress ratio by the available shop
air pressure, the nominal gas pressure can be calculated.
Case in point ( Pump Design: GB25 Fuel booster pump)
Air drive piston location ( 160mm Ø)
CZPT plunger location (32mm Ø)
Actual ratio = 25:1
one. AIR Push Segment
The air travel section is composed of a light excess weight piston complete with seals running within 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 stop).
Under the control of pilot pins (poppet valve) brought on at each and every stop of the stroke
two. 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 examine valve
opens to the greatest allowing gasoline into the gasoline barrel and on the compression stroke
the inlet verify valve closes the discharge verify valve opens forcing the pumped gas
into the approach .The main high pressure seals is located on the gas piston and they seal agaist
the gas barrel during operation . and the maximum pressures of the pump ,however the
CZPT PTFE seals are suitable for equally the large 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 fuel boosters cycle immediately 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
Product variety 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 next question is wheather you want the booster to stall when an outlet stress is reached
If so ,a basic airline pressure regulator will suffice ,but remember the circulation drops off substantially 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 stress are at an air pushed strain of 8 bar or 116 PSI ,for lengthy life utilizing
of this kind of pump ,we recommend that air driven strain need to be not much more than eight Bar .
