Pressure groups with automatic electronic start and stop control and protection against lack of water, silent and maintenance-free. Pressurization for domestic use in houses, apartments, etc. Starting pressure 1.5 Bar. Stop pressure (the maximum reached by the pump). Built-in check valve. Supplied with pressure gauge. Inlet and outlet diameter: 1” male and 1” female respectively. Reset button.

Operation
Integrated dry-running protection. IP 44 protection. Automatic operation with start at 1.5 Bar and stop at the maximum pressure reaching the pump. It has a small accumulation to avoid cyclical starting and stopping in case there is any loss of water in the installation. If there is no water in the pump inlet, it stops automatically.

Fluid: Clean waters and non-aggressive or viscous liquids, free of solid substances.
Maximum fluid temperature: 35 ºC

Flow Controller
Compact device for automatic control and protection of electric pumps. The patented system is equipped with special electronic flow and pressure sensors integrated into the electronic circuit that controls the operation of the electric pump and maintains constant pressure and flow and has a safety system against dry running. OPTIMATIC replaces the traditional autoclave, pressure switch, check valve and level switch system. This device automatically turns on the electric pump when any water point is opened and stops it after a 10-second delay as soon as there is no more water consumption.

Electric Motor
Two-pole induction type, closed and self-ventilated, suitable for continuous operation, with IP55 degree of protection and class F insulation. Single-phase 230V - 50Hz with permanent capacitor. Motors must be thermally protected by the user.
