685S “Snubber”Pulsation Dampener

The Snubber is designed to permit the installation of the Major Level Control on the pump suction line without being affected by surges when the pump starts or stops, or when any other condition results in rapid fluctuation of static head. Of the head type switches in common field use, only the Major Level Control is available with this built-in dampening feature.

Features:

• Simple - Just one additional diaphragm, an orifice, silicone oil, and housing.
• Dependable - Factory sealed snubber assembly eliminates the possibility of orifice plugging from foreign matter.
• Effective - Rapid pulsation pressure peaks up to 30 PSIG result in no visible pointer motion.
• Cost Saving - The Snubber eliminates the necessity of a separate tank connection, and field wiring from the pump unit to the Level Control. The Level Control can be shop mounted and wired on the pump unit skid at a considerable saving in field installation cost.
• Simple Installation - The Snubber can be field installed on an existing Level Control in a few minutes.
