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 .
CZPT DO CZPT models of air pushed fuel boosters that are not suitable for underground
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
Model 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 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
2. No warmth,flame or spark chance
three. Infinitely variable biking speed and output
4. Air driven Designs do not need electrical link ,easy to implement automatic controls
five. No restrict or adverse affect to contineous end/start off applications
six.Seals program made for long operating life,No airline lubricated necessary
seven.Constructed-in coupling system (Most types) and appropriate for most gases boosting

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 .
