Self Contained Air Driven Gas Boosters-Image

SC air driven gas boosters are self contained units, using a cycling spool and pilot valve to provide automatic reciprocating action when air or gas is supplied to the air drive inlet.

The drive consists of a large piston and valve assembly directly connected to a hydrocarbon-free pumping piston with self lubricating seals cycling in a stainless barrel that has an integral check valve.

The working surface area of the drive piston exceeds the working surface area of the pump piston, thereby providing the pressure BOOST. This is accomplished by using relatively low pressure air or gas to the drive inlet. The air drive section is pre-lubricated (thus eliminating the need for an air line lubricator), easy to install, and can be mounted in any position eliminating additional floor space. No electrical connections are required.

SC gas boosters are typically used to boost low pressure gas/air to a higher pressure required at the process or test station. Most industrial gases (nitrogen, helium, hydrogen, argon, etc.) are commonly delivered under pressure in steel cylinders. If gas is to be used at low pressures, e.g., welding, the pressurized supply is easily piped and controlled to the point of use with simple valving. However, if the end use requires the gas under pressure, the supply cylinder pressure connot be utilized after it has fallen to the level of the end use pressure. Therefore, the gas remaining will be wasted unless it is boosted.

If the application requires a pressure greater than the common supply cylinder pressure, a gas booster must be used. Depending on which unit is selected, you can boost gas pressure from 300 psi to nearly 20,000 psi.

SC gas boosters have other applications such as bottle filling from nitrogen generators and dewars, hydrogas suspension systems, automotive air gas storage systems, aircraft slide chute gas storage; sulfur hexafluoride (SF6) transfer for arc suppression and insulation of cicuit breakers commonly found in the utility industry, breathing air for scuba diving, gas injection molding, etc.

In addition to our complete line of gas boosters, SC also fabricates custom gas booster systems for individual applications. These units are manufactured to customer specifications and can include filters, gauges, pilot switches, panel controls, tubular frames, etc. Contact your distributor or our sales department for more information.
