Centrifugal pump casing relief system

A method for monitoring a centrifugal pump within a fluid flow network and relieving said pump of deleterious effects caused by an increased pressure and/or temperature in said pump, said pump communicating with a fluid release valve connected to a fluid conduit, said method comprising:

• selecting a sensor to monitor a variable of said pump;
• providing a fluid control device;
• providing an electrical solenoid operated valve having an inlet connected to said fluid conduit and an outlet and a solenoid operated diaphragm, said diaphragm having a first position and a second position;
• providing a power supply;
• attaching said sensor to said fluid conduit or said network;
• attaching said fluid control device and said solenoid operated valve to said fluid conduit;
• forming an electrical circuit by attaching said sensor and the solenoid operated valve to said power supply;
• and
• moving said diaphragm from said first position to said position second position by completing said electrical circuit to the solenoid of said solenoid operated valve.
