CB2 - 2CPm 25/16B - Single-phase pressure group 2x2 HP
2 SINGLE-PHASE ELECTRIC PUMPS.
2 x 1.5 Kw (2 x 2 HP) motor. Flow rate up to 280 l/min (16.8 m³/h). Head up to 58 m.


COMBIPRESS are pressure groups with two electric pumps assembled in a ready-to-install unit.
The groups are set up so that, with each increase in demand from the user, one or both pumps are automatically started in succession.
This also allows for a significant reduction in electricity consumption since only the pumps needed to satisfy the water demand are activated.
The electronic circuit in the electrical panel alternates the operation of the pumps.
