diaphragm seal swap offers an early warning alert to the potential of dry running situations, cavitation and other pump points that may result in emergency shutdowns and expensive upkeep.

FCI’s FLT93 Series move switch reliably screens the flow and temperature of liquids, gases, and slurries. It is designed for pump wet/dry detection, the place sudden, sudden reductions in media flow charges can depart pumps vulnerable to over-heating circumstances that shutdown course of lines and require troubleshooting and fixing. The SIL2 rated instrument is meant for heavy-duty, probably hazardous course of business environments and comes with a complete record of world security approvals.
It has a no transferring elements design and provides a strong scheme for pump protection with its twin alarm functionality. With Alarm 1, the switch detects a low flow situation anywhere between zero.01 and three ft per second FPS (0.003–0.9 m per second MPS). This low circulate alarm is a pre-warning sign for the control system or operator who can then resolve to keep the pump running or to close it down.
If an Alarm 2 happens as a outcome of the feed line to the pump is working dry, this may be an emergency sign to close down the pump immediately as a end result of the bearings now see gas as a substitute of a liquid as a warmth switch media. In such conditions, the temperature of the bearings might rise very quick. Using a flow swap prevents everlasting harm to the pump’s bearings.
