Bladder Pressure Control System

PULSCO’s Hydropneumatic Pressure Control System is a control and feedback application that maintains water system pressure between a specified pressure range to prevent system pumps from short cycling.

The Bladder System provides superior pressure protection for industries processing potable, raw, wastewater and hydrocarbons. The advantage of this system is the physical separation between the water and compressed air which eliminates the need for level controls. These pressure systems increase the life of your system and save the cost of electro-energy to drive the large pumps.

PULSCO’s Hydropneumatic Bladder Pressure Control System designs are developed from a proprietary program developed especially for pressure control analysis to model the fluid system and offer a low cost alternative for small water system application. From this analysis, the correct pressure 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.
