Wilo-Para R
The OEM safe solution.
The OEM safe solution.
The high-efficiency circulator series Wilo-Para R responds perfectly to the new regulation EN 60335-2-40 on A3 refrigerant gases (up to R290) used in heat pump applications.
The design of Wilo-Para R ensures that the circulator not be source of potential flammability of eco-friendly gases in case of leakage of such one.
It includes a high protection against corrosion, a protection of electronics against any fire ignition and a terminal box made of self-extinguishing material.
The dedicated SCU control mode, as standard version, fits perfectly with low head loss systems and is easy to use and operate with the green push button and LED interface.
The Wilo-Para R can also be used with the external control modes via the bi-directional iPWM1 & iPWM2 signals and the LIN Bus.
The Wilo-Para R series is the safe solution to integrate into new generations of heat pumps.

Your advantages
- Safe solution with a protection of the electronic components against any fire ignition and a terminal box made of self-extinguishing material
- Easily recognizable thanks to a special pictogram
- Easy installation thanks to a compact and standardised design with a front access to the signal connector and screws
- Exists in 3 different control modes to respond better to your specific needs:
- Self-controlled (SCU) version allowing several regulation modes and adjusted predefined settings, easy to handle thanks to the green push button combined with a LED interface
- External control mode through iPWM signal for a direct information on pump status and flow estimation directly from the pump itself
- External LIN control mode allowing many data exchanges between the pump and the appliance to go a step further on digitalisation. Extended functionalities through the LIN extended mode LINX
- High system protection due to integrated functionalities such as air venting, manual restart as well as reset to factory settings upon control mode
- Protection against corrosion thanks to corrosion-free motor housings and screws.
Design
Glandless circulation pump with a cast iron or composite pump housing and threaded or clipped connection. High-efficiency motor with automatic power adjustment, self-protecting modes and protection against any fire ignition.
Application
Hot water heating systems of all kinds, air conditioning and geothermal applications
