text: PULSCO’s Hydropneumatic Bladder Surge Control System designs are developed from a proprietary program developed especially for surge control analysis to model the fluid system and offer a low cost alternative for small water system application. From this analysis, the correct surge tank and components can be sized and determined. The result is a complete and accurate account of system requirements and a reliable solution design for any transient flow problem.
  The tank is designed, built and certified to ASME Sec. VIII, Div. 1 requirements. The tank volume and design pressure is determined by the system's requirements and horizontal or vertical arrangements are possible with capacity ranging from 120 to 8,000 gallons, or to customer specification. The bladder is a heavy Elastomer which is chosen specifically for the application: potable water, raw, water or hydrocarbons. An optional PULSCO Bladder Failure Alarm provides local and remote alarm indication for a ruptured bladder
  The Bladder Pressure Control System produces frequent pump starts and stops during periods of peak service.
  The principal components of the system are the ASME tank, bladder, safety valve, pressure gauge assembly and air charging valves.
