This Cat Pumps Flow Switch is an essential safety and operational control device for the All In One High Pressure Pump Station. It uses a magnetic reed switch mechanism to monitor fluid flow: the switch closes its electrical contacts only when sufficient flow is detected. This signal is then used to control low-amperage components, such as shutting off a burner or preventing the system from running dry.


Key features and benefits include:


  • Flow-Activated Control: Automatically controls the on/off operation of system components, activating when flow is above 0.8 GPM and opening the contact when flow drops below this minimum.
  • High-Pressure Rating: Built to withstand the demands of high-pressure cleaning systems, with a Maximum System Pressure of 3650 PSI (250 bar).
  • Durable Construction: Features a Brass body for excellent corrosion resistance and robust components, including a magnet covered by a plastic casing to minimize interference from metal particles.
  • Electrical Safety: Rated for 12-230 Volts (Max Amperage 3 Amps, Max Switch Capacity 60 VA) and features an insulation class of IP55.
  • Standard Connection: Equipped with 3/8 inch BSP(M) (British Standard Pipe Male) fittings on both the inlet and outlet ports.
  • Application: Critical safety and control component used in the All In One High Pressure Pump Station.
