Also popularly found on espresso machines are steam wands which are used to steam milk and then froth it for specific coffee beverages.

Gaggia’s version uses a handle and manual pumping action to push the heated water through the coffee grounds. The commonly used term, “pulling a shot”, derives from the usage of this maker because of the need to pull the handle several times to complete the task. There are two different styles of the piston espresso machines. The manual version which works by the operator pushing the water through by way of the handle alone and the spring driven version that uses a tensioned spring to build up the pressure.
Pump: Pump espresso makers work by using a motor to build up force to brew the coffee. This style is the popular option for most coffee shops. Business grade machines generally hook right in to the locations plumbing to attain the water needed, but smaller versions for home use come with a built in area to hold water. The ones used in coffee shops tend to work faster then the ones you will find in homes.
Steam: Steam driven espresso machines are just as simple as they sound. Steam pressure builds to push the water through the coffee grounds and it is about as simple as that. The first espresso coffee machines created employed this type of functioning and because they require no moving parts are still used today because of the cheap manufacturing process.
