Some pumps have a gauge that shows the pressure of air that is forced into the tire. Once the tire is at the correct pressure, the pump valve can be removed from the tire, and the cap can be replaced on the tire valve. There are two main types of tire valves to which the bicycle tire pump attaches. These are the Presta valve and the Schrader ...
There are adapters to fit a Schrader pump on a Presta valve, but loss/theft of the adapter can still be an issue. Adapters can leak, a disadvantage compared to a Schrader chuck on a Schrader valve. At very high speed - approximately 150 kph - Schrader valves can open under centrifugal force, leading to a flat tire.

Where it is necessary to raise water to a height above that to which a suction or lift pump will operate effectively (about 7 metres), or to raise the pressure so that it will exit a nozzle with a strong force, such as through a fire hose, a force pump may be used. As with a suction pump, in its manual form it relies on an operator to pump a ...

The Roots blower is one example of a vacuum pump. A vacuum pump is a type of pump device that draws gas particles from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity. [1]
