Features

Product Specs

The Kenco NO-FLOW SWITCH (“NFS”) is designed to protect the engine and compressor cylinder(s) against lubrication failure. The Kenco “NFS” mounts in line between the lubricator and cylinder. On start up, the first stroke of the lubricator automatically opens the “NFS” switch contact. The contact is opened and closed by the precision-fit plunger inside the “NFS” body. Lubricator oil flows through the body with the rate of flow controlled by the amount of oil that passes between the precision-fit plunger and the bore inside the body. If the lubricator stops pumping, the precision-fit plunger will drift back against the switch contact and stop the engine.

Switch Contact Electrical Rating: 2 amps, 30 VAC or VDC
Switch Contact Circuitry: Case-To-Ground

Flow Rates Required to Open Switch Contact:

6 drops per minute or more when using standard plunger spring
Between 3 and 6 drops per minute when using optional light plunger spring “L” (See ordering note below)

Maximum Recommended Working Pressures:

NFS-3, NFS-4, NFS-5, NFS-30: 2,000 psig
NFS-6, NFS-11: 4,000 psig
NFS-7, NFS-9, NFS-25: 1,750 psig (Consult factory for other available rupture pressure settings)
