The Astoria CMA brand is one of the few brands which use a specific type of motor on their espresso machines, a water cooled motor. This is also the case with the Astoria Divina espresso machine. Note: there is also a external motor available.
The water cooled engine is made by the Italian company RPM. This motor is available in a 120V and a 230V version. The 120V model produces 310W and the 230V 330W. The water cooling of this motor is done by wrapping a copper tube around the body of the motor. The water passing this motor goes to the water inlet.
The external motor is also a motor made by RPM. This motor is a 120V or a 220/230V model and produces 262W. On the outside is a junction box installed, so that you can wire your cables in a protective box.
Both these models of pumps are fitted with a clamp on ring for the espresso machine pump. But with Astoria espresso machines you always have a coupling set. These are spacers between the pump and motor. So this assembly requires 2 stainless steel clamps.
You can fit a variety of pump brands on these pumps, but they do need to be clamp on pumps. These can be from brands such as Fluid o tech, Procon and Nuert. They need to produce around 180/200 L/H.
