The advantages of this device are basically the integration into a single compact device: a pressure sensor to control the start pressure, a flow sensor to manage the stop pressure and to prevent dry-running operation of the pump, a membrane giving elasticity to the hydraulic net avoiding constant starts and stops of the pump due to water leakages in the installation, a check valve, easily adjustable starting pressure and a pressure gauge.
Basically, this device starts the pump when a tap/valve is opened in the installation and stops the pump when water consumption is finished.
Based on these premises, they have been developed over the years a wide variety of devices to suit market needs.
- No maintenance.
- Installation time saving.
- Protection against water hammer effect.
- Compact and reduced dimensions.
- Removal of protecting devices (level switches).
- Avoids the pump oversizing using integratelly their flowpressure curve.
- Integrated protection system again dry working for lack of water.
Is the cut in pressure adjustable?
Yes, be aware of the maximum presure the pump need to acheive to switch off at no flow.
