Premium Energy Storage & Pressure Control Solutions for Hydraulic Systems
Hydraulic accumulators are essential safety and efficiency components in any industrial hydraulic system. Whether you need energy storage, emergency backup, shock absorption, or pressure stabilisation, a correctly-sized hydraulic accumulator improves overall system life, helps reduce pump cycling, and protects critical components.
We offer a full range of hydraulic accumulators for sale, including HYDAC hydraulic accumulators, from approved and trusted suppliers. Contact our HYDAC accumulator distributors team for supply, service, and engineering support.
What Is an Accumulator in a Hydraulic System?
A hydraulic accumulator stores pressurised fluid using a nitrogen-charged chamber, then releases that stored energy when needed to support demands such as:
- Energy storage for peak demand periods (allowing smaller, energy-efficient pumps)
- Shock & pulsation dampening to prevent hydraulic hammer, noise, & vibration
- Emergency power supply during pump failure or power outage
- Pressure maintenance to compensate for internal leakage or thermal expansion
- Flow supplementation for fast-acting hydraulics & high-response actuators
- Fluid separation/transfer barrier when fluids cannot mix
This improves reliability, safety, and productivity in modern hydraulic systems across manufacturing, construction, defence, mining, agriculture, and aerospace.
