Wilo-RainSystem AF 400
Wilo-RainSystem AF 400
Your advantages
- Low-noise due to optimised overall flow and noise concept (multistage centrifugal pumps)
- Maximum operating reliability through the use of fully electronic RainControl Hybrid controller
- High economic efficiency due to needs-based fresh water replenishment
- Automatic control of the feeding pump
- System/level control in low-voltage range
Recommended services
RainSystem AF 400-2MP 304 - 605
Design
Automatic rainwater utilisation system with hybrid tank (400 litres) and two non-self-priming pumps from the MultiPress MP series
Application
Commercial and industrial rainwater utilisation for conserving drinking water as a hybrid system in conjunction with rainwater storage tanks or vessels
Equipment/function
- Connection-ready module with compact construction
- Completely connected, electrically and hydraulically, and mounted on vibration-insulated baseplate, comprising:
- 2 non-self-priming, corrosion-free, low-noise MultiPress series centrifugal pumps
- R 1 1/2 joint tubing on the pressure side, including transmitter unit with 8-l diaphragm pressure vessel following the flow-through principle and shut-off device with draining, manometer 0–10 bar
- Ball valve on suction and pressure sides and non-return valve
- A large-volume hybrid tank with all connections, non-turbulent supply lines and overflow with siphon
- RainControl Hybrid central switchgear with control electronics, 4–20 mA pressure transmitter and level control in the low-voltage range
- Signals concerning operation and malfunctions
- Steady system control by means of cyclical pump cycling and integrated test run on idle pumps
- Automatic fault-actuated switchover and peak-load operation
- Automatic water exchange in the replenishment reservoir
- Permanent display of rainwater storage level, system pressure, operating status via LCD (optional)
- Including DVGW-certified R 1 solenoid valve for the drinking water replenishment

Construction
- Ready-to-connect water-supply unit with 2 water-supply pumps as compact module for commercial and industrial rainwater utilisation
- For fully automatic supply with rainwater from ground reservoir or rainwater storage tank using submersible motor pumps as feeding pumps
- Depending on the pump dimensioning, greater distances between the system and rainwater storage tank can be bridged over with this hybrid system (see also Wilo submersible motor pumps, Wilo-Drain series)
- High-volume hybrid tank with all integrated functions offers needs-based replenishment of drinking water in the consumer network when rainwater storage tanks are not full.
- Fully-electronic control unit for controlling the water supply and cistern pump, equipped with main switch, control switch for each pump with Manual-0-Automatic function and display of the operating status operation/fault for each pump as well as low-water display
- Depending on the pressure, pumps are switched on and off in cascade according to the need for water
- Diaphragm pressure vessel for energy savings in the event of smallest leakages in buildings
- Steady system control by means of cyclical pump cycling and integrated test run on idle pumps.
- Automatic fault-actuated switchover and peak-load cut-in guarantee maximum system availability.
- In the event of low water, the system is switched off by built-in dry-running protection
- Including integrated electronic motor protection
- Control device displays extensive signals; it is also equipped with potential-free contacts for collective run signals and collective fault signals
- System is ideal for connection to building management system (GLT/DDC)
Scope of delivery
- Two noise-reduced, normal suctioning, multistage centrifugal pumps
- 400 l hybrid tank with all required connections, transmitter unit with 8 l diaphragm pressure vessel, central switchgear, RainControl-Hybrid with control electronics and level control device of Wilo-Drain TM or TS cistern pumps in three-phase version (optionally in single-phase version) to be ordered separately
