Wilo-RainSystem AF 400

Automatic rainwater utilisation system with hybrid tank (400 litres) and two non-self-priming pumps from the MultiPress MP series

Commercial and industrial rainwater utilisation for conserving drinking water as a hybrid system in conjunction with rainwater storage tanks or vessels

• 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

• Operating pressure max. 10 bar
• Protection class: IP 54
• Connections:
  • Pressure pipe/pressure-side joint tubing R 1 ½
  • Inflow pipe HT 50
  • Overflow connection DN 100

• Pump housing made of 1.4301 stainless steel
• Impeller made of Noryl
• Shaft made of 1.4028 stainless steel
• Mechanical seal made of ceramic/carbon
• Stage chambers made of Noryl
• Diaphragm expansion tank, steel, painted

• 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)

• 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

• Rainwater storage level indicator
• Operating hours counter
• Individual run/fault signals
• Clock timer
• 3~230 V, 50 Hz
• 60 Hz versions
• Extension module AF 400
