Wilo-Para
The most reliable OEM solution.
The most reliable OEM solution.
The high-efficiency circulator series Wilo-Para is dedicated to heating and air-conditioning applications.
Its compact design and predefined standard settings make commissioning and setup very easy.
The circulators can be either self-controlled (Dp-v, Dp-c, n-constant) or externally controlled through iPWM or LIN Bus interface.
Wilo-Para is compact and offers a large choice of pump housings and options. This enables a very high integration flexibility.
The Wilo-Para series, especially with its LIN control mode, allows many development opportunities in the field of intelligent functionalities. This new generation of circulators is dedicated to make your life easier.

Your advantages
- High integration flexibility due to compatibility with former standard and high-efficiency series and a wide range of specific pump housings
- Easy installation thanks to a compact and standardised design with front access to signal connector and screws
- Exists in 3 different control modes to respond better to your specific needs:
- Self-controlled (SC) version allowing several regulation modes and settings, easy to handle thanks to the green push button combined with a LED interface
- External control mode through iPWM signal for 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
Eco-friendly features
- High-efficiency pump with automatic power adjustment (EEI ≤ 0.20)
- Integration of various external control modes to maximise the overall efficiency of the heating system
- Sustainable and carbon-neutral production and processes in our European factories
Design
Glandless circulation pump with a cast iron or composite pump housing and threaded or clipped connection.
EC motor with automatic power adjustment and self-protecting modes.
Application
Hot-water heating systems of all kinds, air-conditioning applications

Options
Variant Wilo-Para*/H available for heat pumps
The high-efficiency circulator series Wilo-Para */H is dedicated to respond to the new regulation EN 60335-2-40 on R32 refrigerant gas used in heat pump applications.
The design ensures the protection of the heating or air-conditioning systems against any risk of high flammable R32 gas leakage.
It includes a protection of the electronics against any fire ignition and a terminal box made of self-extinguishing material.
Easily recognizable with the pictogram R32 on the front.
