The DA-7 gas booster is designed for 100,000 psi max service.
The low pressure (2,000 psi max) drive equipment consists of oil reservoir, electric motor and pump, pressure regulating valve, directional control valve, driving pressure indicating gage, a differential filtering system and a hydraulic check valve.
The high pressure ends consist of two piston-cylinder assemblies proportioned for 2 stage compression, optimizing the efficiency and minimizing the thermodynamic heat of compression. The first stage discharges slightly more gas than the second stage requires. An interstage cooler and receiver, check valves, necessary high pressure piping, and interstage and high pressure discharge instrumentation are supplied.
These boosters will accept bottle pressures (as low as 500 psi) as the inlet source – higher inlet pressures are preferred for increased pumping performance. Relatively large high pressure pistons and long strokes result in high volumetric efficiencies and slow pistons speeds to minimize maintenance.
The DA-7 gas booster is designed for manual operation.
