All espresso machines (regardless of the machine model) start with a water source. In some devices, there is a small tank for water, and some are directly connected to the main plumbing. Tank machines are usually used for low-volume applications, but a high-volume professional espresso machine requires a reliable source with plumbing connections.
A good espresso needs pure and clean water that does not contain too much (or too little) mineral salt. For this reason, most espresso machines have internal filters. In addition, the water normally does not have enough force to extract the coffee extract to produce a good espresso. Hence, the espresso machine needs a pump.
In many modern espresso machines, an electric pump is used to generate the required force and pressure. Espresso production requires about 9 times the atmospheric pressure at sea level or 130 PSI (PSI is the unit of pressure measurement in “pounds per inch”). To get a better understanding, consider that the recommended pressure for most car tires is between 30 and 35 PSI.
Normally, there are two types of espresso pumps in espresso machines:
- Industrial and commercial machines usually have a complex rotary pump to provide constant pressure. These types of pumps use an electric rotor that is powered by a mechanical disk.
- Most home espresso machines also use a vibrating pump. These pumps have an electromagnetic coil to push and pull the piston. These vibration pumps only start working when you start extracting.
The water tank built into the device has a capacity of 1.8 liters. The body of Bomann espresso maker EM 502 GS is made of aluminum alloy and stainless steel. This feature allows you to use the device for years without worry. It is also completely resistant to pressure and impact. The filter placed on this device is made of stainless steel.
