Pressostat SK-9 230V 1-phase pour pompe domestique pompe puits

General description Pressostat SK-9 is a mechanical pressure switch designed for domestic water installations operating at 230V. It is suitable for various applications including water pumps, expansion tanks, and garden pumps. This single-phase device automatically activates the pump based on water pressure, ensuring efficient operation. Technical specifications Input voltage: 220-240V Max current: 10A Max pressure: 6 bar Pressure adjustment range: 1.4 to 4.1 bar Start pressure adjustment: 1.4 - 2.8 bar Temperature range: 0 - 55°C Connections: 13 mm (1/4 inch) Weight: 0.376 kg Dimensions (H x L x W): 110 mm x 105 mm x 65 mm Material: Metal / Plastic Color: Black Protection class: IP44 (splash-proof) Installation To adjust the pressure switch, follow these steps: Loosen the differential nut (2) Set the start pressure (1) Tighten the differential screw (2) to the stop pressure Note: If your pump exceeds 1.1 kW, a power connector or relay must be installed upstream. Usage The pressostat operates by monitoring the water pressure in the circuit. When the pressure drops below a certain threshold, the pump is activated and will stop once the desired pressure is restored. Other information Reference: 50622 Registration number WEEE: DE45283704
