Description
Glanded twin-head pump in in-line design with flange connection.
-
Advantages
- Reduced life cycle costs through optimised efficiency
- 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
- Main/standby mode or peak-load operation (by means of external auxiliary device)
