Vertical bladderless water hammer tank

Vertical compressor-based vessel, no bladder or membrane — 2,000 L to 35,000 L — 6 to 30 bar

Vertical water hammer tank operating without a bladder or membrane: the air cushion is replenished by a compressor controlled by water level, rather than by a replaceable elastomer element. This design removes the most heavily stressed wear part found in bladder tanks, and particularly suits large capacities and operators looking to minimise maintenance on internal components.

Connection	Flanged (DN250 — DN700 depending on capacity)
Volume	2,000 L — 35,000 L
Pressure	6 to 30 bar depending on model
Orientation	Vertical
Regulation	Water-level-controlled compressor
Manhole	DN400 (2,000—15,000 L) / DN500 (18,000—35,000 L)

• No bladder/membrane to replace — no elastomer wear
• Air cushion automatically replenished by a level-controlled compressor
• Flanged process connection, DN increasing with capacity (DN250 to DN700)
• Manhole for inspection and internal maintenance
• Suited to large capacities (up to 35,000 L) and networks requiring high availability
