How does an air driven hydraulic pump work?

Air driven liquid pumps work on a standard reciprocating differential area principle utilizing a large air drive piston connected to a smaller hydraulic piston/plunger to convert compressed air power into hydraulic power. The maximum air drive pressure rating on all pumps is 160 psi.

What are the three types of hydraulic systems?

Three common varieties of hydraulic fluids found on the market today are petroleum-based, water-based and synthetics.

• Petroleum-based or mineral-based fluids are the most widely used fluids today.
• Water-based fluids are used for fire-resistance due to their high-water content.

Can a hydraulic system get air locked?

Even air that has become trapped in oil will usually get transported back to the reservoir at some point. However, bleeding air from a hydraulic system can speed up this process. It’s common knowledge that air trapped in a system can cause mechanical damage and lead to erratic operation.

What are the advantages of air driven hydraulics?

Air driven hydraulics have some significant advantages over conventional electric motor or engine driven hydraulics. They are explosion proof. Additional controls such as motor starters are not required. They will stall and maintain pressure with no energy consumption. They are capable of variable rates of flow .

When to use air driven hydro test power packs?

Air-driven Hydro-test Power Packs A variety of different configurations are available to generate pressures of up to 65,000 psi. Typically used for pressure-testing large diameter pipelines, hose umbilicals and wellhead control valves. Also used for chemical injection, pre-charging hydraulic accumulators and operating subsea valves.

When was the first air driven pump made?

Founded in the 1953, the company manufactured a range of specialist hydraulic components and remote controls. In 1985, under a new and aggressive ownership, the company expanded with its first range of air driven pumps and power packs. Reciprocating piston pumps and high pressure systems became the focus of their business.

What kind of products does hydronic Corporation make?

Air driven fluid pumps and hydraulic power units are core products for Hydronic Corporation. Founded in the 1953, the company manufactured a range of specialist hydraulic components and remote controls. In 1985, under a new and aggressive ownership, the company expanded with its first range of air driven pumps and power packs.
