They work by pushing hot coffee through the ground with high pressure. This produces a concentrated shot that is full of flavor. It is a rich source of caffeine, which can be an effective stimulant.
These types of machines come in a range of sizes, from small models that are ideal for homes to larger ones that are designed for commercial use. These machines are available in manual and semi-automatic versions. Manual machines require the operator to manually regulate the flow of water and pressure while semi-automatic models have an inbuilt pump that handles this for you. Some semi-automatic machines include a grinder, while others don't. The kind of machine you choose will be based on your personal preferences and budget.

It features an under-chamber that holds the water and an upper chamber with an iron filter. When it's heated, the steam from the water is pushed through the grounds and into the top chamber, from where the brewed espresso is ready to serve.
Varieties

These machines are still available however they are not as frequent due to the amount of effort required and the fatigue they can cause. Modern espresso machines utilize various mechanisms to generate pressure, including screw, push and see-saw designs. This lets the user control pre-infusion and water volume more precisely than the lever machine.
Pump-driven espresso machines are similar to stovetop mokapots, however, they use an electric motor to press the grounds of coffee, instead of steam. The boiler heats the water to boiling point, and a pump then forces the water through the group head. These are the most common types of espresso machines and they're generally less expensive than other models.

But, because they lack steam functions, you'll need an additional milk frother to make lattes and cappuccinos.
In the 19th century a large number of cafes in Europe relied on steam machines to reduce brewing time and boost production. But these early machines were heated by an open flame, which resulted in a fluctuating temperature and pressure. Inventor Angelo Moriondo of Turin, Italy is credited with creating the first machine capable of making espresso without steam.
The most popular type of espresso machine in use today is a pump-driven machine. The machines employ portsafilters to hold the ground espresso beans. When the valve is set to the espresso position it extracts the coffee and espresso maker espresso through water at 15 atmospheres of pressure from a heating vessel. After the brew is completed, the portafilter is removed and then emptied to be cleaned.
