Features

• Air cushion in direct contact with pipeline fluid absorbs positive and negative pressure transients caused by pump trip or rapid valve closure
• Integrated compressor variant maintains air volume on a timed or pressure-actuated cycle, compensating for dissolved air loss over time
• Passive suction cup variant replenishes air without external power, suited to remote or unmanned installations
• Carbon steel or stainless steel pressure shell; design per client specification and site hydraulic analysis
• Capacities from 100 litres to 120,000 litres, sized per transient hydraulic analysis
• Manufactured to PED 97/23/EC and internationally recognised pressure vessel codes including EN 13445 and ASME VIII-Div.1

Notes

• Specify required capacity in litres when enquiring (range: 100–120,000 L). Vessel is sized per site hydraulic transient analysis. Specify air maintenance method: integrated compressor or passive suction cup.

Description

Hydropneumatic surge vessel with air cushion in direct contact with the pipeline fluid. Air volume maintained by integrated compressor (timed or pressure-actuated) or passive suction cup for remote installations. Absorbs pressure transients from pump trip or valve closure. Suited to raw water, irrigation and industrial applications. Capacities from 100 to 120,000 litres, sized per hydraulic transient analysis.
