Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
There are two types of pneumatic systems currently used in naval aircraft
When you need to inflate the tires.
Thre's really no way of answering that, as the capacity of bicycle pumps isn't defined. So, you'd have to look at the human powering the bicycle pump. And given that you can only use your arms powering the pump Id say 1 kW tops.

Hydrolic
Pneumatic = Air! There are brake systems that use a combination of both pneumatic and hydraulic components. In those combination braking systems you would use the hydraulic brake fluid that the manufacture specifies.
Pneumatic, use of air. Hydraulic, use of oil or other fluid.
Pneumatic tube systems today are most seen at the drive-through windows of banks. Pneumatic tubes use pressured air to push a sealed object through the system. how do pneumatic truck trailers work?
A pneumatic system is based on the property of gases to compress and expand easily when pressure is applied or released. This property allows pneumatic systems to use air or other gases to transmit force and energy to operate various mechanisms and components.
A basic Pneumatic system can contain simply 3 things: - An air supply (compressor) - A 3/2 valve - A single acting cylinder. This is a simple system that will open and close something when a button is pressed/released.
