Pressure switch domestic pumps SKD1 230V single phase cable included

The pressure switch automatically starts and stops the water pump by the opening and closing of the valve. As a result, there is a constant pressure in the water pump. If there is no water, the dry running protection is activated and the pump stops working. The pressure switch reduces the effects of water hammer. The pump controller consists of hydraulic and electronic parts: The hydraulic part: • Stop valve • Valve sensitive to flow change • Form-pressed and enhanced plastic body • Membrane and spring sensitive to pressure change • Check valve that prevents water leaks when the membrane is damaged The electronic part: • A robust casing from self-extinguishing and form-pressed plastic • A single tested and controlled electronic card with insulated conducting path. • A relay with a switching capacity of approx. 100.000 cycles during continuous operation with a maximum charge of 1.1 KW. • A varistor (additional protective element) against voltage spikes and surges. The pressure switch goes together with 2 cables (protective contact coupling/ plug), each 1.35 m long.
