Wilo-Sub TWI 5/TWI 5-SE
Multistage, submersible, rainwater storage tank pump.
-
Description
Wilo-Carus Air Super is the ideal solution to provide continuous air venting of closed heating and chilled water circuits in domestic and commercial buildings. The design with protective cap and the expansion sealer rings prevents leaks.
The long distance between the water and the closing mechanism as well as the conical shape of the cap reduce the possibility of contamination.
-
Advantages
- Higher efficiency of the heating and chilled water system thanks to the intelligent “open closed”- principle of the float valve
- High reliability and less maintenance by removing free air out of the system
- No water contamination through the conical shape and long distance between water level and venting valve
- Reduced noise level thanks to efficient air venting
-
Technical Features
Design
Multistage, submersible, rainwater storage tank pump.
Application
- Designed for pumping drinking water (in accordance with ACS) and rainwater with up to 50 g/m³ sand content from wells and rainwater storage tanks for irrigation, sprinkling and water supply.

Construction
Rainwater storage tank pump in monobloc design with radial impeller as multistage hydraulics.
Single-phase current motor with sheath flow cooling. The motor is cooled by the pumped fluid. The motor is equipped with automatic thermal motor monitoring.
The motor itself is dry. Two mechanical seals are used to seal the motor and the fluid. There is an oil separation chamber between the two mechanical seals. The oil separation chamber is filled with white oil and absorbs leakage through the seal on the fluid side.
Connection cable with fitted plug.
