Pressure Switch for Water Jet Pump Parts – 100 psi, Model No. 72131267-Pressure-Switch-100-psi-Water-Jet-Pump-Parts.871.3-1

Introduction, Application, Features, and Maintenance:

This component is a pressure switch designed for water jet pump systems. It is an electromechanical device that monitors fluid pressure and activates or deactivates an electrical circuit when pressure reaches a preset threshold of 100 psi, enabling automated system control or safety functions.

Application:
Used in water jet cutting machines to monitor low‑pressure water supply, hydraulic fluid, or abrasive slurry circuits. Typical installations include pump inlet pressure monitoring, filter condition indication, or safety interlock systems where pressure must be maintained within safe operating limits.

Features:

• Pressure setpoint: 100 psi (6.9 bar).

• Provides electrical switching for automated control or alarm functions.

• Manufactured from corrosion‑resistant materials suitable for water and abrasive slurry exposure.

• Adjustable or factory‑preset switching point depending on design.

• Compact design for easy installation in machine panels or fluid lines.

• Reliable operation under varying system conditions.

Maintenance:

• Regularly inspect the pressure switch for signs of corrosion, leakage, or damage.

• Verify that the switch activates at the correct setpoint using a calibrated pressure source.

• Check electrical connections for proper function and signs of wear.

• Replace the switch immediately if it fails to activate, sticks, or shows signs of leakage.

• Clean the pressure port periodically to prevent clogging.

• Follow the manufacturer’s recommended calibration and maintenance schedule.
