Wilo-Para-ST
The OEM solution for solar thermal application.
The OEM solution for solar thermal application.
The high-efficiency circulator series Wilo-Para ST is dedicated to solar thermal applications.
Its high static pressure and compatibility with wide temperature variations make this circulator fully adapted to this specific application.
Its compact design and adjusted predefined settings make its commissioning and setup very easy.
The self-controlled mode version (SC) is easy to use and to operate with the green push button and LED interface.
The external control via LIN Bus and the bi-directional iPWM2 signal provide information about the operating status or the flow rate.
The Wilo-Para ST series fits perfectly to demanding mechanical requirements of solar thermal applications.
Recommended services
Your advantages
- High integration flexibility due to compatibility with former standard and high-efficiency series
- Easy installation thanks to a front access to the 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 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
- High system protection due to integrated functionalities such as air venting, manual restart as well as reset to factory settings upon control mode
- Mechanical design dedicated to solar thermal systems
Design
Glandless circulation pump with a cast iron pump housing and threaded connection. High-efficiency motor with automatic power adjustment and self-protecting modes. Mechanical design dedicated for solar thermal applications.

Example: | Para ST 15-130/7-50/SC-12 |
Para | Electronically controlled high-efficiency pump. Pump range adapted to requirements of the OEM market. |
ST | Dedicated to solar applications |
15-130 | Nominal diameter - Pump housing length (inline cast iron) |
7-50 | Nominal delivery head range [m] - Power consumption [W] |
SC | SC = self controlled pump ; Δp-v, Δp-c, constant speed I, II, III |
iPWM = the pump is controlled by an external system via iPWM2 signal | |
LIN = the pump is controlled by an external system via Lin Bus Communication |
