Automatic Pressure Control Switch For Pressure Boosting Water Pump

This pressure switch is suitable for cold and hot water automatic self-priming pumps, household booster pumps, pipeline pumps and other water pumps. It can automatically control the start and stop of water pumps, featuring simple operation, stable performance, equipment protection and power consumption saving. Select according to required pressure.

Technical Parameters: Rated Voltage: 220V (allowable error ±10%) Rated Current: 16A

Thread Types:

Male Thread: 1/4 inch male thread, diameter 12.5mm;

Female Thread: 3/8 inch female thread, diameter 15mm;

Product Material:

1. The bottom of this switch is made of zinc alloy. Low-cost inferior products on the market use plastic. Zinc alloy is durable, corrosion-resistant, and can withstand high pressure without water seepage or leakage.
2. It adopts silver dual-contact clutch. (The contact has 15 contact surfaces, which is more stable than a single round-point contact.) It ensures the operating strength of the switch with stable and reliable quality and long service life, preventing frequent startup!

Marking Instructions:

Example (1.5–2.2kg): Technical explanation – the water pump starts when the water pressure reaches 1.5kg and stops working at 2.2kg pressure.

If you are unsure how to buy a suitable pressure switch, here are two methods for you:

1. Check the label on the original pressure switch or the nameplate parameters of the water pump. The pressure switch section will show xxkg – xxkg;
2. Contact me for model matching. Just provide the brand, model, power and maximum head of the machine.

Pressure Range: (Model selection by pressure)

1.0~1.8kg (for 125W)

1.5~2.2kg (for 250W, 300W, 370W)

1.8~2.6kg (for 550W)

2.2~3.0kg (for 550W, 750W)

2.5~3.3kg (for 750W)

Product Application: This switch is applicable to fully automatic cold and hot water self-priming booster pumps of major domestic and overseas brands, for elbows with internal and external threads.

After the copper sheet is pressed to separate the contacts, it can be seen that the four contact surfaces are all white silver surfaces. That is, the genuine double contact pressure switch

Adjustment Operation:

(Disconnect the power supply first) Use a screwdriver to remove the screws on the plastic cover. Turn to “+” to increase pressure and turn to “-” to decrease pressure.

Pressure Adjustment:

1. If the pump starts frequently when the tap is opened, increase the pressure by turning the knob 1 to 3 circles towards the plus sign.
2. If the pump keeps running after the tap is closed, reduce the pressure by turning the knob 1 to 3 circles towards the minus sign.

(There are various causes for the pump failing to shut down, mainly classified as follows: damaged switch, poor sealing of the check valve causing pressure backflow, pressure leakage due to pipe leakage, and insufficient pressure caused by wear of the pump impeller.)

Product use: The switch is suitable for automatic cold and hot water self-priming booster pumps of major brands at home and abroad, and for elbows with internal and external threads.
