If you need greater pressure (higher lift) we recommend the CM Booster 3-5. The CMB 3-5 pumps 38 litres/minute @ 380 kPa (more than enough to get up the fourth floor of a building). If you need more water in a single storey home, this pump delivers about 67 litres/minute @ 250kPa.
The CMB 3-5 is fitted with the advanced PM controller (PM2) which features options of a maximum continuous operating time (30 minutes), an auto reset function and much more.
With a rated power consumption of 689W the CMB 3-5 is still energy efficient compared to most other pumps of this size. The CMB 3-5 now also comes with 2 years additional warranty (registration required).
