China Professional CZPT Model: GB02 Maximum 16 Bar Air Driven Gas Booster Pump for Vacuum Refilling manufacturer

Product Description

 USUN Model :GB02   160MM driven pneumatic driven natural Gas Booster Pump

for Charging Cylinders


Usun air driven gas booster  pumps are ratio devices that utilize low pressure compressed


air driving a larger diameter piston (area x pressure) which is linearly connected to a smaller


hydraulic piston/plunger. Using this ratio principal, a higher hydraulic pressure can be generated.


Usun Pump model numbers reflect the pumps nominal pressure ratio, while the technical data 


indicates exact ratios.  The outlet stall pressure is easy to set by adjusting the air drive pressure


through a simple air pressure regulator. By multiplying the pressure ratio by the available shop


air pressure, the nominal gas  pressure can be calculated.


Example ( Pump Model: GB25 Gas booster pump)


Air drive piston area ( 160mm Ø)


Hydraulic plunger area (32mm Ø)


Actual ratio = 25:1




The air drive section consists of a light weight piston complete with seals running inside an


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


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


(forces as out of the gas end).


 Under the control of pilot pins (poppet valve) triggered at each end of the stroke



The gas section of a USUN 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 maximum allowing gas into the gas barrel and on the compression stroke


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


 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 maximum pressures of the pump ,however the


standard PTFE seals are suitable for both the vast majority of gases encountered .


Other materials of construction  can be supplied to meet more aggresive services  


.The standard  serials of booster are not suitable for underground coal mine applications  .


USUN DO Manufacture models of  air driven gas boosters  that are not suitable for underground

coal mine applications .

USUN Air driven gas 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  .


USUN 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

USUN for flow conditions not shown in charts   

Model selection 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 pressure is reached 

If so ,a simple airline pressure regulator will suffice ,but remember the flow drops off dramatically 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  .

Yes, there are noise considerations to take into account when using piston vacuum pumps. Here’s a detailed explanation:

– Piston vacuum pumps can generate noise during their operation, which is important to consider, especially in environments where noise levels need to be minimized.

– The noise produced by piston vacuum pumps is primarily caused by mechanical vibrations and the movement of internal components.

– The noise level can vary depending on factors such as the design and construction of the pump, the speed of operation, and the load conditions.

– Excessive noise from piston vacuum pumps can have several implications:

– Occupational Health and Safety: High noise levels can pose a risk to the health and safety of operators and personnel working in the vicinity of the pump. Prolonged exposure to loud noise can lead to hearing damage and other related health issues.

– Environmental Impact: In certain settings, such as residential areas or noise-sensitive locations, excessive noise from piston vacuum pumps may result in noise pollution and non-compliance with local noise regulations.

– Equipment Interference: Noise generated by the pump can interfere with the operation of nearby sensitive equipment, such as electronic devices or precision instruments, potentially affecting their performance.

– To mitigate the noise produced by piston vacuum pumps, several measures can be taken:

– Enclosures and Sound Insulation: Installing acoustic enclosures or sound-insulating materials around the pump can help contain and reduce the noise. These enclosures are designed to absorb or block the sound waves generated by the pump.

– Vibration Isolation: Using vibration isolation mounts or pads can help minimize the transmission of vibrations from the pump to surrounding structures, reducing the noise level.

– Maintenance and Lubrication: Regular maintenance, including lubrication of moving parts, can help reduce friction and mechanical noise generated by the pump.

– Operating Conditions: Adjusting the operating conditions of the pump, such as speed and load, within the manufacturer’s specified limits can help optimize performance and minimize noise generation.

– Location and Placement: Proper positioning and placement of the pump, considering factors such as distance from occupied areas or sensitive equipment, can help minimize the impact of noise.

– It is important to consult the manufacturer’s guidelines and recommendations regarding noise levels and any specific measures to mitigate noise for a particular piston vacuum pump model.

– Compliance with local regulations and standards regarding noise emissions should also be considered and adhered to.

In summary, noise considerations are important when using piston vacuum pumps to ensure the health and safety of personnel, minimize environmental impact, and prevent interference with other equipment. Measures such as enclosures, vibration isolation, maintenance, and proper operating conditions can help mitigate the noise generated by these pumps.
