Wilo-Para G
The OEM solution for geothermal application.
The OEM solution for geothermal application.
The high-efficiency circulator series Wilo-Para G is dedicated to geothermal applications.
The self-controlled mode version (SC) is easy to use and operate with the green push button and LED interface.
The external control via LIN Bus and the bi-directional iPWM1 signal provide information about the operating status or the power consumption.
The motor housing and the screws are specially designed with corrosion protection. With a minimum fluid temperature of -20°C the circulators are suitable for use in brine circuits.

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 a front access to signal connector and screws
- Exists in 3 different control modes to respond better to your specific needs:
- Self-controlled (SC or SCU) versions 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 power information 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 functionalities such as air venting, manual restart as well as reset to factory settings upon control mode
- Protection of the motor housing and screws against corrosion
Design
Glandless circulation pump with a cast iron pump housing, corrosion-protected motor housing and screws, threaded connection.
Application
Circulation in geothermal systems at a fluid temperature range of -20°C to +95°C

Example: | Para G 15-130/7-50/SC-12 |
Para | Electronically controlled high-efficiency pump. Pump range adapted to requirements of the OEM market. |
G | Dedicated to geothermal application |
15-130 | Nominal diameter - Pump housing length (inline cast iron) |
7-50 | Nominal delivery head range [m] - Power consumption [W] |
SC | SC or SCU (low head loss system) = self controlled pump ; Δp-v, Δp-c, constant speed I, II, III |
iPWM = the pump is controlled by an external system via iPWM1 signal | |
LIN = the pump is controlled by an external system via Lin Bus Communication | |
12 | Position of electronic module |

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.
