Air Driven Liquid Pump
The air driven liquid pump is pneumatically driven reciprocating piston pumps. These pumps are proportional devices that utilize low pressure compressed air to drive a larger diameter piston (area x pressure) that is linearly connected to a smaller hydraulic piston/plunger. Utilizing this ratio principle, higher hydraulic pressure can be generated. Materials of construction include standard all stainless steel wetted ends and polyurethane pressure seals. Specialized materials of construction and special seals are also available upon request. Compact and lightweight, this liquid pump requires no air lubrication and is suitable for water, oil and most chemical applications.
Principle of operation - Easy to operate
Getting Started:
Connecting supply lines
Compressed air, suction and pressure lines
Setting the drive pressure
Slowly open the compressed air supply to start the pump
Building pressure:
The pump can build up pressure automatically
Automatic circulation of the slide valve using air pulses from the pilot valve
Pumping liquids
Favorable circulation conditions due to large cross section
Maintains pressure:
Pump maintains pressure
Pump stops automatically when pressure is reached
Pressure maintained with no heat loss or energy consumption
Pump will automatically restart when pressure drops
Advantages
Pressure controlled by manual pressure regulator or pneumatic valve
Suitable for use in explosion-proof areas
Suitable for most liquids or liquefied gases
Pump stops automatically when a predetermined pressure is reached
No energy consumption during the holding phase
Easy installation and trouble-free operation
Required connections: supply, suction and pressure lines
Reliable operation
Applications
High pressure pneumatic liquid pumps are available in a variety of sizes for use in many industries including oil and gas, mining, construction, aviation, aerospace, automotive, biomedical, vegetable oil extraction, alternative energy, chemical, defense, food processing, hydraulic fracturing, and more.
