Piston Accumulators — Sales, Repair & Reseal in Edmonton

A piston accumulator uses a sliding piston to separate the nitrogen charge from the hydraulic fluid, which lets it handle high flow rates, large gas volumes, high working pressures and wider temperature extremes than other types. Northland supplies, reseals, rebuilds and charges piston accumulators for large and demanding hydraulic systems across Edmonton and Alberta — every major brand.

How piston accumulators work

In a piston accumulator, a free-floating piston moves inside a honed cylinder, compressing the nitrogen charge on one side as hydraulic fluid enters the other. That design suits high-flow, high-pressure duty and large storage volumes, and the piston seals are the main wear item we service.

Applications

Piston accumulators are chosen where flow, volume, pressure or temperature is high:

●        Large hydraulic systems and power units

●        High-flow and high-pressure applications

●        Large-volume energy storage

●        Wide temperature-range and demanding duty cycles

●        Heavy industrial, oil & gas and mining equipment

Piston accumulator sales

We supply piston accumulators in a range of bore sizes, volumes and pressure ratings, and can size the right unit to your system. See accumulator sizing.

Repair & reseal

Piston accumulators are serviced by resealing the piston and rebuilding with OEM-quality parts, then pressure-testing and recharging. We reseal and rebuild piston accumulators in-shop and return them ready to install. See accumulator repair & rebuild.

Charging

We set and verify nitrogen pre-charge on piston accumulators in-shop or on-site. See accumulator nitrogen charging.

Brands

We supply and service piston accumulators from HYDAC, Parker, Bosch Rexroth, Olaer, Tobul and more.

Frequently Asked Questions

  • Piston accumulators handle high flow, high pressure and large storage volumes, so they’re used on large hydraulic systems, power units and heavy industrial, oil & gas and mining equipment.

  • Yes — piston accumulators are resealed and rebuilt with new piston seals and OEM-quality parts, then pressure-tested and recharged. It’s usually far cheaper than replacement.

  • Yes — we reseal and rebuild piston accumulators with new piston seals and OEM-quality parts, then pressure-test and recharge them before return.

  • Piston units handle higher flow, larger volumes and wider temperatures; bladder units respond faster and excel at shock and pulsation dampening. We’ll help you choose the right type — see accumulator sizing.
