Water Pump Pressure Switch 220V Adjustable 10 Bar Automatic Electronic Controller with Reflux Valve Protection

Compact pressure control switch for water pumps designed for reliable automatic pressure management and easy replacement of worn or faulty switches. Key benefits Adjustable start and stop pressure for precise pump control and flexible system tuning. Wide measuring range 0 to 10 bar to cover common residential and light commercial pump needs. Built with durable materials and rated for long operational life: 140000 cycles. Simple NPT 1/2 in (20 mm) threaded connection and standard 220 V power for broad compatibility. Reflux valve design that allows internal circulation if the outlet becomes blocked, protecting the pump from pressure spikes. Specifications Measuring range: 0 to 10 bar Intended scope: water pump control Voltage: 220 V Interface: NPT 1/2 in (20 mm) Control mode: adjustable start and stop pressure Maximum fluid temperature: up to 80 C Service life: approximately 140000 cycles Size: 11.5 x 8.7 cm (4.53 x 3.43 in) Weight: 552 g Package contents 1 x Pressure control switch Note: Include adapter only if requested. Please specify if an adapter is required. Important operational notes The product uses a reflux valve design. If the water outlet is blocked the motor may continue running; in that situation the reflux valve opens and water circulates inside the pump to prevent pressure buildup. Plan system controls accordingly and avoid assuming automatic motor shutoff when the outlet is obstructed. Verify thread compatibility before installation and request an adapter when needed. Compatibility and typical applications Compatible with submersible pumps, selfpriming pumps, jet pumps, and deep well pumps. Use scenarios: 1) Household water supply system: automatic pressure control for booster pumps feeding domestic plumbing. 2) Small irrigation system: maintains steady pressure for garden or small agricultural irrigation. 3) Industrial transfer and sampling: suitable for sewage sampling and flow liquid transfer in lownoise installations. Why choose this switch Offers a balance of accuracy, adjustability, and durability for routine pump control tasks. Easy to install as a direct replacement for many standard pressure switches with NPT 1/2 in connections. Clear performance limits and behavior noted so you can integrate it safely into existing pump systems.
