It means that the pressurising medium does not leave the system and it is recirculated with make-up or top-up quantity as and when required. This makes it a sealed system to work with.
Pneumatic system is operated by compressed air while hydraulic system is operated with pressurised hydraulic oil or any type viscous oil. Hydraulic systems can usually produce higher control forces and work under extreme operating conditions. This is the system that is primarily used on aircraft to move control surfaces and engine controls. You can often classify pneumatic systems because they have a pump (gas pump) and hydraulic systems have a piston. That is the difference. Also, pneumatic systems are louder because it is a gas under pressure. 1. By definition, hydraulics is used in controlling or harnessing power with the use of pressurized fluids whereas pneumatics studies how pressurized gases influences mechanical motion or movement. 2. Hydraulics uses an incompressible fluid medium like oil whereas pneumatics uses a compressible gas like air. 3. Hydraulic applications demand greater pressures during operations that reach thousands of pounds per square inch whereas pneumatic applications only require 100 psi pressures more or less. 4. Most hydraulic applications generally use bigger components that pneumatic applications. 5. Hydraulic systems are generally more difficult to operate compared to pneumatic applications
Generally hydraulic systems are closed circuit, meaning that the liquid used (generally oil) is filtered and stored in a reservoir. pneumatic systems are often open, as air from the atmosphere is compressed in a tank before it is used, then released into the atmosphere afterward. the air tank is either charged before operation of the system, or continuously replenished by a compressor, (the compressor is run by a prime mover). the primary disadvantage of pneumatics, is that gas can be compressed, and decompressed, this is an advantage for storage, but makes control difficult. hydraulic systems do not have this problem, but the liquid in the system must be recirculated, thus requiring more maintenance, and also storage, as liquids do not compress. this is beneficial to control, because the liquid in a hydraulic actuator cannot be compressed, this provides rigidity when the liquid is not flowing, and precision when it is. another benefit of this rigidity is that good leverage is not needed in hydraulic systems many pieces of heavy machinery use third class levers with hydraulics because the mechanical advantage of a large hydraulic piston combats the poor leverage, a telescopic handler, wheel loader, and telescoping crane excellent examples of this.

what made genetic engineering possible
a device driver is software, making communication between your motherboard and your OS, probably Windows, possible.
Boston scientific makes many non invasive products. These include cellular phones, personal computers, personal in home movie systems, and surround sound systems.

According to the internet, KuDos makes on of the most reliable hydraulic crimper in the world. The company website states they are the most reliable manufacturer.
A telehandler is basically a forklift truck where the actual forklift is placed on a hydraulic lifting system. This makes it possible to reach places with the forklift which basic forklifts cannot reach.
How much hydraulic fluid with how much gasoline makes a big difference and was some hydraulic oil mixed into the gas tank or was some gasoline mixed with the hydraulic tank. More info please.

restricted return fluid
Hydraulic systems are known as force multipliers because they allow a relatively small input force to generate a much larger output force. This is achieved through the use of incompressible fluid that transmits pressure equally in all directions, amplifying the force applied. This makes hydraulic systems ideal for lifting heavy loads or performing tasks that require high force.
