Sulfur hexafluoride supply in the electronics industry

Multiphase booster pumps were developed by Hydraulics International Inc. specially for handling different liquified gases such as freons, halogens, CO₂, LNG etc.

Multiphase boosters HII are designed for handling fluid in any phase from 100% gas phase to 100% liquid phase.

HII multiphase pumps basic line is represented with 5 models for solving standard tasks of liquified gases handling. This basic line can be supplemented with liquid pumps line and gas boosters line to handle any special engineering task.

• Drive type: air driven;
• Discharge pressure range: 5 - 86 bar (70 - 1250 PSI) basic line, 2000 bar max. (30,000 PSI);
• Hydraulic part types: single-acting / double-acting;
• Number of stages: single stage, two stage;
• Inlet fluid phase: from 100% gas phase to 100% liquid phase
• Outlet fluid phase: from 100% gas phase to 100% liquid phase;
• Wetted parts lubrication: NO lubrication, no fluid contamination;
• Air drive lubrication: grease lubricant;
• Minimum gas evacuation level (model 5LG-TS-4): to 27” HG
• Minimum inlel gas pressure (other models): approx 3 barg;
• Maximum inlet fluid pressure (liquid or gas): equal to max. discharge pressure.

• Сlean design of the all wetted parts - no lubricats, no fluid contamination, ideal for handling high-purity fluids;
• Ideal for charging, maintaining constant pressure, recharging, gas evacuation;
• Unlimited start and stop cycles - from stend-by pressure maintenance operation to hard cyclic operation;
• Smooth and simple pressure adjustment in a wide pressure ranges from 0 to MAX;
• Fire and explosion proof;
• No electrical parts;
• Compact and lightweight - mobile design;
• Designed for handling fluid in any phase from 100% gas phase to 100% liquid phase;
• Positive suction / cavitational restrictions do not exist by definition;
• Possibility of gas liquefaction by pressure;
• Possibility of gas evacuation to moderate vacuum;
• Inert to dust, moisture, weather conditions.

• Not designed for handling fluids, contaminated with mechanical impurities;
• Flow restrictions - not designed for high flows.
