12V FL40 FRONT END SWITCH

12v FL40 Front End Switch

Automatic Pressure Control for 40 PSI Diaphragm Pumps

Keep your diaphragm pump operating automatically with the FL40 Control Switch, a practical replacement pressure switch designed for compatible 40 PSI diaphragm water pumps.

This compact switch controls the pump's power according to water pressure, allowing the pump to start and stop automatically as you open and close a tap or valve.

When you open a tap, the pressure in the water system drops and the switch allows the pump to start. Once the tap is closed and the system reaches the required shut-off pressure, the switch automatically stops the pump.

It's a convenient solution for maintaining automatic water delivery without having to manually switch your pump on and off.

Why You'll Love It

• 40 PSI Pressure Rating: Designed for compatible 40 PSI diaphragm pump systems.

• Automatic Pump Control: Starts and stops the pump according to changes in water pressure.

• Convenient Operation: Allows your pump to respond automatically when taps or valves are opened and closed.

• Ideal Replacement Part: Suitable for replacing a worn or faulty control switch on a compatible diaphragm pump.

• Compact Design: A practical component for compatible water pressure systems.

• Less Manual Switching: Helps maintain convenient, pressure-controlled water delivery.

How Does the FL40 Control Switch Work?

The FL40 Pressure Control Switch responds to changes in pressure within your water system.

1. Open a Tap or Valve: Water pressure drops as water begins to flow.

2. Pump Starts: The pressure switch activates the connected diaphragm pump.

3. Close the Tap: Pressure builds up in the system.

4. Pump Stops: Once the required shut-off pressure is reached, the switch automatically cuts power to the pump.

This makes it a useful component for diaphragm pump systems where automatic operation is needed.

Ideal Applications

The FL40 Control Switch is suitable for compatible pressure-controlled diaphragm pump systems, including:

• Diaphragm Pump Repairs: Replace a worn or faulty pressure switch.

• Portable Water Pump Systems: Maintain automatic pump operation.

• Caravan & Camping Water Systems: Control compatible pumps supplying taps and water outlets.

• Small Water Pressure Systems: Automatically manage pump operation as water demand changes.

• Water Transfer Equipment: Suitable for compatible diaphragm pumps requiring a 40 PSI pressure switch.

Important Information

• Switch Only: This listing is for the FL40 Control Switch. The diaphragm pump is not included.

• Check Compatibility: Confirm that the switch is suitable for your specific diaphragm pump model before purchasing.

• Pressure Rating: The switch is designed for compatible 40 PSI systems. Ensure the pressure setting matches your pump's requirements.

• Electrical Compatibility: Confirm that the switch's voltage and current ratings are suitable for your pump.

• Dry-Run Protection: The original product information mentions run-dry control, but this should not be treated as confirmed protection against running without water.

• Correct Installation: Follow the pump manufacturer's instructions when fitting or replacing the switch.

If your 40 PSI diaphragm pump is no longer switching on or off correctly, the FL40 Control Switch may be a practical replacement part to help restore automatic pressure-controlled operation.
