OMT Diaphragm Accumulators
OMT diaphragm accumulators store hydraulic energy and smooth pressure surges in a robust, low-maintenance package. With electron-beam welded construction and a metal diaphragm clamping ring, they deliver reliable performance across a wide pressure and temperature range — ideal for systems where space is tight and uptime matters.
Key Specifications
- Nominal volume: 0.07 to 3.5 litres
- Maximum working pressure: up to 350 bar
- Diaphragm materials: NBR (standard), IIR, FKM, ECO — others on request
- Temperature range: dependent on diaphragm material (e.g. NBR, FKM, ECO each rated differently)
- Oil-port options: G1/2" and G3/4"
- Gas-port connection: M28x1.5
Applications
Energy accumulation and controlled energy delivery, plus pulsation damping to reduce vibration and noise from pressure surges. Suited to a wide range of hydraulic systems.
