Got Questions? We Have Answers.

A hydraulic piston accumulator is an energy storage device that uses a floating piston to separate compressed nitrogen gas from hydraulic fluid — storing and releasing pressure as your system demands.

Hydraulic fluid enters the accumulator under system pressure, compressing the nitrogen gas. When pressure drops, the gas expands and pushes the fluid back into the circuit — stabilizing pressure instantly.

Piston accumulators handle larger volumes, higher pressures and wider temperature ranges. Bladder accumulators respond faster but are limited in volume. The right choice depends on your system requirements.

Our piston accumulators operate between 50 to 750 bar — suitable for both standard industrial systems and extreme high-pressure hydraulic applications across various industries.

Piston accumulators are widely used in oil and gas, steel, automotive, marine, chemical, pharmaceutical, construction, mining and power generation industries across India.

Sizing depends on required fluid volume, operating pressure range, flow rate, cycling frequency and system response time. Our technical team performs detailed sizing calculations to find the perfect match.

Routine maintenance includes quarterly nitrogen precharge checks, annual seal inspections, monitoring for external leakage and verifying smooth piston movement — adjusted based on duty cycle and operating conditions.

Yes. Piston accumulators tolerate fluid contamination better than diaphragm types due to robust metal-to-metal guidance and sealing. However, maintaining ISO 4406 cleanliness standards is always recommended.
