The Murphy Pulsation Damper (PD8183) Series eliminates pointer flutter on pressure indicating Swichgauge devices which are subject to pulsating pressure from reciprocating pumps or compressors. It also allows a close setting of high and low contact points providing for more accurate pressure indication and control of equipment. It is recommended a pulsation damper is used in conjunction with the OPL switchgauges
The PD8183 Series decreases wear on geared movements and increases the life of pressure indicating instruments by eliminating excessive gauge strain and unnecessary movement, a necessity which quickly pays for itself by protecting any pressure indicating and control instrument which is subject to pulsation.
