Pulsatrol Installation, Operation, & Removal Instructions
The PULSAtrol is a pneumatically charged diaphragm-type chamber that intermittently stores energy.
Used on the inlet, it will improve NPSHA (Net Positive Suction Head available) characteristics of the
suction piping system. On the discharge line it will reduce peak pressures and pulsating flow variations.
