Switching operating modes in Wilo Yonos is made using a separate switch. It is possible to use fixed settings. For the most economical power consumption, the module can be switched to automatic mode.

The Wilo Yonos pump control unit has an indicator panel, where all information about power, system pressure and other parameters is displayed. In addition to the usual installation length of 18 cm, production of small-sized devices of 130 mm was launched.

The company produces pumps of two subspecies:

• with a dry rotor;
• with a wet rotor.

This type of pump indicates that the rotor of an electric motor has no contact with water. The connection of the engine with the working part is made with the help of special sealing rings, which will not allow the used fluid to be in the electric drive.

This unit consists of two parts: the 1st part is the electric motor itself, the 2nd part is the body with two branch pipes - one branch pipe of the injection type, the other - the suction side. In addition, it has an impeller that performs pumping.

The main indicators of the device:

• high level of efficiency - more than 80%;
• It is necessary to install filters to prevent foreign objects and particles from entering the product.

In the room where this equipment will be installed, there should be no dust, otherwise the sealing rings will quickly become unusable. It will be quite difficult to replace the rings, only a specialist can do it. Type of connection, as a rule, flange.

This product is often used for domestic needs. The device of such pumps will differ significantly from other models. The motor and the impeller are located in the housing itself, which has both an inlet and an outlet. The transfer of the coolant is carried out as if by the rotor itself, which is equipped with an impeller.

The bearings are cooled and lubricated by the pumped liquid itself. This product is used in heating systems with a small length and small pipe diameters.They are connected by a threaded connection.

Main equipment indicators:

• almost silent operation;
• has the most compact execution;
• if necessary, you can change the parameters of work, which will help to significantly save on electricity consumption;
