USUN Model:2AGB150 Max.20000Psi Double Head 6 Inch Driven High Pressure Air Driven Gas Booster Testing Pump

USUN Model:2AGB150  Max.20000Psi Double Head 6 Inch Driven High Pressure Air Driven Gas Booster Testing Pump  

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: AGB30 Gas booster pump)

Air drive piston area ( 160mm Ø)

Hydraulic plunger area (32mm Ø)

Actual ratio = 25:1

1.  AIR DRIVE SECTION

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

2. GAS  DRIVEN SECTION

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  .
