Your advantages

• Reduced life cycle costs thanks to optimized efficiency
• Standard condensate drainage holes in the motor housings
• Can be used flexibly in air-conditioning and cooling systems, with application benefits due to direct draining of condensate via optimised lantern design (patented)
• High standard of corrosion protection thanks to cataphoretic coating
• High worldwide availability of standard motors (according to Wilo specifications) and standard mechanical seals

Construction
Glanded pump in in-line design with flange connection.
