LEWCO 10-gallon and 20-gallon Pulsation Dampeners help smooth the flow by counteracting the pulsations that are typical of positive displacement reciprocating pumps.
Simple and durable, LEWCO Pulsation Dampeners are completely field serviceable, and their bladders are interchangeable with leading brands. A standard replaceable bottom plate helps reduce maintenance costs when pumping abrasive or corrosive fluids. A large top flange permits replacing the urethane or Buna-N (nitrile) diaphragm bladder without removing the unit from the line. The body is made of two forgings welded together using the sub-arc process.
All dampeners also feature a stainless steel charge valve and pressure gauge, located on the top flange and protected by a heavy-duty cover which also serves as a lifting eye. LEWCO Pulsation Dampeners are ABS & DNV certified, and 100% NDE tested. Most importantly, LEWCO pulsation dampeners are compatible with most mud pumps.
