Features of Air Driven Liquid Pumps
- Air drive line lubrication is not required.
- Self-priming for immediate operation.
- Compatible with all hydraulic fluids, plain water, distilled & deionized water, solvents, mild chemicals and most liquefied aerosol type gases.
- Range of models provide up to 80,000 psi intermittent output pressure.
- Stainless steel hydraulic body, check valves, and trim are standard
- Alternative gases that can drive the pump include nitrogen, vapor from liquefied gas, pipeline natural gas and sour natural gas with proper modifications.
- Offer a wide range of standard modifications.
Advantages of Air Driven Liquid Pumps
- Hydraulic pressure is held without energy consumption.
- Explosion proof as it requires no electrical power or connections.
- Intrinsically safe.
- Compact, lightweight and weatherproof.
- Easy to adapt automatic controls.
- Contamination tolerant.
- Outlet stall pressure pre-determined by the air drive regulator.
- High pressure capability - up to 80,000 psi.
- Ideal for stop-start applications under full load.
- Easy to install and operate.
- Hydrostatic Testing. Any component that is made to hold liquid or gas pressure needs to be carefully tested after manufacture or repair to verify its integrity, and/or to calibrate it. Air driven pumps can simplify this requirement in a broad range of industries.
- Clamping-pressing-releasing. Hydraulic cylinders or rams that are required to maintain an output force without movement for long periods need a hydraulic pump that can maintain output pressure at zero flow for a long periods with no heat being generated. Air driven pumps will do this over virtually any pressure range.
- Valve Actuation. Pipeline gas is commonly used for bootstrap operation of pneumatic valve actuators. But where high force requirements meet low gas pressures, the size of the pneumatic actuator needed may be impractical. A gas driven pump with a small hydraulic actuator can often solve this at less cost.
- Portable Hydraulic Tools. To be easily handled on the job, these tools must be compact with minimum weight. This means hydraulic pressures beyond the reach of rotary hydraulic pumps but easily provided by air driven hydraulic pumps.
