  • Separation between drive and gas section uses three dynamic seals with dual vents
  • Air drive line lubrication not required
  • Rugged soft-seat, high-flow check valves in gas section(s)
  • Only hydrocarbon-free stainless steel, bronze, PTFE and Viton gas section internal parts exposed to gas flow
  • Heat of compression reduced for long seal life because cold exhaust air surrounds gas barrel(s) inside cooling sleeve(s)
  • Standard trim is weatherproof and suitable for offshore service
  • High pressure capability - up to 4,500 psi
  • Boost directly from unregulated high pressure gas cylinders or pipelines
  • Maintain gas purity
  • One-man portable

Hydraulics International 5G-SS-14 Booster Pump is a Single Action, Single Drive, Single Stage Booster Pump with 1,300 psi Max Outlet Pressure and 100 psi Min Inlet Pressure both based on 95 psi Drive.

An air (or gas) driven gas booster has a continuously reciprocating drive piston section directly connected to one or two gas boosting sections. The drive section includes a four-way air cycling valve and dual air pilot valves to provide the continuous reciprocation. Normally, start/stop control is accomplished by cutting off drive- or pilotair input.

The Maximum Gas Section Pressures vary by model. The Maximum Drive Section Pressure is 150 PSI for all models.

GAS PURITY: Most gases used in industry and life support must be clean and dry. Otherwise, the end use is severely compromised. Gases needing purity include argon (Ar), carbon dioxide (CO2), helium (He), hydrogen (H2), neon (Ne), nitrogen (N2), nitrous oxide (N2O), oxygen (O2) and breathing air. If gas purity is needed, all devices used to transfer gas or increase gas pressure must be completely dry and free of any lubricants. Hydraulics International, Inc.’s (HII’s) air driven gas boosters satisfy this requirement. No hydrocarbon lubrication is needed in the gas sections because the high pressure pistons slide on inert PTFE dynamic seals. And because gas barrel temperature is controlled with the cold drive air exhaust, long seal life is ensured.

HIGH PRESSURE OUTLET: Most mechanically driven gas compressors can only handle 5,000- to 6,000-PSI requirements. Mechanically driven units that can handle over 6,000 PSI are rare and costly. If gas purity is required, most of these higher-PSI units need high-pressure and high-maintenance purifiers installed—to compensate for hydrocarbon carryover created by oil-lubricated pistons. Air driven gas boosters do not suffer from these shortcomings and are therefore better suited for higher-PSI applications. HII’s standard air driven models are hydrocarbon-free and available in 50- to 25,000-PSI capacities.

BOOST DIRECTLY FROM HIGH PRESSURE GAS CYLINDERS: A mechanical compressor cannot inhale common industrial gas cylinder pressure. The inlet pressure must be reduced, usually close to 0 PSI. This is a costly waste of energy. Air driven gas boosters have no such limitation, greatly enhancing the efficiency and simplicity of high pressure gas applications where the gas source is typically supplied from portable DOT cylinders.
