High flow solar pump unit

S2 solar 2 is the high-flow solar pumping unit suitable for integration in forced circulation solar thermal systems. It is used to transport the fluid from the solar panels to the user's exchanger.

Installs in less than half an hour thanks to the included accessories that facilitate mounting on the wall or on the kettle. Its innovative and compact design makes it modern, stylish and space-saving.

• High head pump
• Thermometers and safety group
• Temp continues: 120 ° C (max 160 ° C for 20s)
• PN 10

Members of the group of solar pumping

Non-return valve

This special non-return valve inserted inside both the delivery branch and the return branch.

seals and ensures low pressure drop to the advantage of system efficiency.  By turning the handle 45 ° it is possible to exclude it in case of maintenance. (e.g. system emptying) 

Flow regulator

The groups of pumping solar have important characteristics that improve the stability of the system, such as the presence of a practical flow regulator that allows easy operation of the plant.
This fact shows the taps of loading / unloading in a close position, thus minimizing the residual air in circulation after the loading operation.

Recirculation pumps high prevalence

The high temperature solar pumping group is available with 2 types of wet rotor circulators:
the Wilo Para 1-7 or the Wilo Para 1-8. Both circulators are safe and reliable over time thanks to resistant materials and advanced electronics, they allow three different speed stages that can be manually set to adapt to the desired performance. 

Security group for solar systems

In the secondary circuit is a security group contains the following features:
- 3 valve and pressure gauge bar 63 mm 0-4 bar. 
- Connection 1 1 / 2 "male hose or kit. 
- O connection 1 "Female pipe or kits.
The connection to the fitting to "T" is secured by a special sealing system with OR preloaded EPDM, which does not require the use of sealing pastes.
