All boilers are required to have a pressure gauge, which can be mounted on the front or side. A Bourdon pressure gauge is typically used on a high pressure boiler. Safety valve: The safety valve protects the boiler against extreme high pressure inside the drum. It allows for blowoff when the working pressure gets too high.

It is the pump that produces a force so that the water creates a flow. Unlike a motor engine which uses the movement of the piston to turn the crankshaft, the pump relies on the crankshaft movement to drive the pistons. This movement allows the water to flow in and out of the pump. There's a common misconception that a pump produces the pressure.
