Hydro Multi-E booster sets from Grundfos Pumps come as pre-assembled packages on a base plate — complete with sensors, manifolds, diaphragm tank, dry-run protection, valves and fittings. There is a built-in frequency converter on each pump with a speed range from 2900 to 3600 rev/min
Other features include energy-efficient permanent-magnet motors for many models. The speed-controlled cascade achieves large energy savings compared to traditional booster systems.
These sets are available with two, three and four pumps. They can be connected to all major field-bus systems.
