Types of Accumulators
Northland stocks and services the three main accumulator types — bladder, piston, and diaphragm — so we can match the right technology to your pressure, flow, and duty cycle.
BLADDER ACCUMULATORS: Bladder accumulators respond fast and excel at shock containment and high-frequency pulsation dampening, which makes them the workhorse for mobile equipment, industrial machinery, and hydraulic power units. We stock, charge, and rebuild bladder units and carry replacement bladders and repair kits. Learn more on our bladder accumulators page.
PISTON ACCUMULATORS: Piston accumulators handle high flow, large gas volumes, and high working pressures, and they tolerate wider temperature extremes — making them ideal for large hydraulic systems and demanding duty cycles. We service and reseal piston units and supply seal kits. See our piston accumulators page.
DIAPRAGM ACCUMULATORS: Diaphragm accumulators are compact and highly durable, which suits smaller hydraulic circuits, instrumentation, and space-restricted mobile applications. See our diaphragm accumulators page.
Accumulator Service & Repair
Beyond sales, Northland is a full-service accumulator shop: repair and rebuild, nitrogen charging and pre-charging, pressure testing and and sizing support — for units we sold and units we didn’t.
Repair & Rebuild
Our repair service covers complete teardown; inspection of the shell, ports, valve assembly and bladder; replacement of worn components with OEM-quality parts; and functional testing before the unit returns to service. We replace bladders and seals and rebuild bladder, piston, and diaphragm accumulators. Details on our accumulator repair & rebuild page.
Nitrogen Charging & Pre-Charging
Correct pre-charge pressure is critical to accumulator performance and life. We verify and set nitrogen pre-charge, recharge units that have lost gas, and confirm pressure to spec — in-shop or on-site. See accumulator nitrogen charging.
Testing & Inspection
We pressure-test and leak-inspect accumulators so you can return them to service with confidence. Accumulators are pressure vessels, so proper testing and documentation matter — especially on regulated Alberta job sites.
Sizing & Selection
Choosing the wrong size or pre-charge is the most common cause of accumulator problems. Give us your application, system pressure, and volume and we’ll size and select the right unit. Use the form below or see accumulator sizing.
Our Accumulator Repair Process
1. Inspection: We inspect the shell, ports, valve assembly, bladder, and overall condition to identify issues.
2. Disassembly: The accumulator is safely disassembled and all internal components are inspected.
3. Rebuild: Damaged components are replaced with OEM-quality parts and the unit is reassembled.
4. Testing: Each accumulator is pressure tested, charged before returning to service.
Every repair is backed by our workmanship and decades of hydraulic experience.
Industries We Support
We keep accumulators running for Alberta’s heavy industries — oil & gas, mining, forestry, manufacturing, construction, and power generation. From presses and power units in the shop to drilling rigs and mobile equipment in the field, we service the accumulators your operation depends on.
Accumulator Problems We Solve
Most accumulator trouble shows up as one of three symptoms. Here’s what each usually means:
● “My hydraulic system feels slow or spongy.” — Often an incorrect pre-charge or a failed bladder.
● “My pump cycles too frequently.” — The accumulator is losing its nitrogen charge and needs recharging or repair.
● “Pressure spikes are damaging components.” — Accumulator failure, or a unit that’s incorrectly sized and no longer absorbing shock.
If any of these sound familiar, see the signs of a failing accumulator, or send us your details for a diagnosis.
Accumulator Brands We Service & Supply
We service and supply all major accumulator brands, including HYDAC, Parker (Greer), Bosch Rexroth, Olaer, Tobul, and Enerpac. Don’t see yours? We service all makes and models — just ask. See brands we service.
Accumulator Safety — Handle Stored Energy Correctly
Hydraulic accumulators store significant energy under high-pressure nitrogen, so incorrect disassembly, discharging, or depressurizing is genuinely dangerous. Always have purging, charging, servicing, and pressure diagnostics done by qualified technicians. Northland’s team is trained to handle accumulators safely and to the standards Alberta job sites expect.

Frequently Asked Questions
-
A hydraulic accumulator stores energy by holding hydraulic fluid under pressure against a compressed nitrogen charge. That stored energy smooths pressure spikes, dampens pulsation and shock, supplies emergency or backup power, and helps stabilize system performance — reducing wear on pumps and components.
-
Common signs are a slow or spongy system, a pump that cycles too frequently, pressure spikes that damage components, or an accumulator that won’t hold pressure. These usually point to a lost nitrogen charge, a failed bladder, or a unit that needs recharging or rebuilding.
-
Most accumulators can be repaired or rebuilt rather than replaced. We replace bladders and seals, rebuild bladder, piston and diaphragm units with OEM-quality parts, and pressure-test and recharge them before return. If a unit is beyond economical repair, we’ll tell you and supply a replacement.
-
Pre-charge is the nitrogen pressure in the accumulator with no hydraulic fluid in it, and it must match the application to work correctly. We verify and set pre-charge with dry nitrogen, adjust it to spec for your system pressure, and confirm the reading — in-shop or on-site.
-
We service and supply all major brands, including HYDAC, Parker (Greer), Bosch Rexroth, Olaer, Tobul, and Enerpac, plus makes we didn’t sell. If you have an accumulator from another manufacturer, contact us — we service all makes and models.
-
Yes. We charge, test, and service accumulators both in our Edmonton shop and on-site across the region, which keeps mobile equipment and fixed plant running with less downtime. See our mobile / on-site hydraulic repair service for coverage.
-
Sizing depends on your system pressure, the fluid volume you need to store or absorb, and the duty cycle. Send us your application, system pressure and volume using the form and our specialists will size and select the right unit — getting this right prevents most accumulator problems.
-
Yes. We pressure-test and leak-inspect accumulators. Because accumulators are pressure vessels, proper testing and documentation matter on regulated Alberta job sites — talk to us about your certification requirements.
