High flow solar pump unit

S2 solar 2 is the group of solar pumping at high flow rates suitable to be integrated in solar thermal systems with forced circulation. Is used for the transport of the fluid from the solar panels to the heat exchanger user.

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 is inserted inside of the delivery branch that in the return branch.

seals and ensures low pressure drop to the advantage of system efficiency. By turning the handle you can exclude 45 ° in case of maintenance. (Eg, emptying the system)

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 unit 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, allowing three different speed stages that can be set manually 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.
