3. Features

Automatic Start & Stop
The pump activates and shuts off automatically based on water demand, minimizing energy use and reducing system wear.

Adjustable Start Pressure
Easily fine-tune the starting pressure with the top-mounted adjustment screw to better suit your specific water usage needs.

Dry-run Protection
Automatically powers off the pump when no water is detected, effectively preventing damage caused by dry running.

Fault Indicator
Built-in LED display quickly alerts you to any system faults, making troubleshooting simple and efficient.

Industrial-grade PCB
Constructed with premium electronic components and reinforced terminals for enhanced durability and long-lasting performance.

Copper-core Relay
Features a copper coil and silver oxide tin contacts for excellent electrical conductivity and reliable switching action.

Upgraded Diaphragm
The thickened rubber bladder withstands pressures up to 15KG, offering superior resistance to rupture.

High-Temperature Check Valve
Fitted with a heat-resistant ABS triangle valve and sealing ring that can handle temperatures up to 120°C while preventing backflow and leakage.

Heavy-duty Spring
Made from quenched manganese steel, the thickened spring resists deformation and ensures consistent pressure control over time.

4. Applications

Ideal for use with pipeline pumps, booster pumps, self-priming pumps, and circulation pumps.

Important Note:
This controller is designed to manage pump activation and shutdown only. It does not increase or boost water pressure.

5. FAQs

Q1: Does this controller increase water pressure?
A1: No, it only controls the pump’s start and stop functions. The actual water pressure is determined by your pump.

Q2: Can I manually adjust the startup pressure?
A2: Yes, the controller includes a screw-type adjustment on the top, allowing you to easily set the startup pressure to suit your needs.

Q3: How do I wire the controller correctly?
A3: Use 0.75–1.5mm² copper wire. If your pump has only two wires, the ground wire is optional. Make sure the copper wires are fully inserted and screws are tightened securely to avoid arcing or damage to the circuit board.
