Diaphragm Accumulators — Sales & Service in Edmonton
A diaphragm accumulator uses a flexible diaphragm to separate the nitrogen charge from the hydraulic fluid in a compact, sealed shell, making it durable and well suited to smaller hydraulic circuits, instrumentation and space-restricted mobile applications. Northland supplies, services and charges diaphragm accumulators across Edmonton and Alberta — every major brand.
How diaphragm accumulators work
In a diaphragm accumulator, a rubber diaphragm flexes as hydraulic fluid enters and leaves the shell, compressing the nitrogen charge above it. The compact, welded or threaded design is highly durable and ideal where space and weight are limited and volumes are small.
Applications
Diaphragm accumulators fit compact, lower-volume roles:
● Small hydraulic circuits
● Instrumentation and control systems
● Space-restricted and mobile applications
● Pulsation dampening and small-volume energy storage
● Pressure stabilization
Diaphragm accumulator sales
We supply diaphragm accumulators in a range of sizes and pressure ratings and can size the right unit to your circuit. See accumulator sizing.
Service & charging
We inspect, test and set the nitrogen pre-charge on diaphragm accumulators, and supply replacements where a sealed unit can’t be rebuilt. See accumulator nitrogen charging and testing & certification.
Brands
We supply and service diaphragm accumulators from HYDAC, Parker, Bosch Rexroth, Olaer and more.
Frequently Asked Questions
-
Diaphragm accumulators are compact and durable, so they’re used for small hydraulic circuits, instrumentation, pulsation dampening and space-restricted mobile applications.
-
Some diaphragm accumulators are serviceable, while sealed (welded) types are replaced rather than rebuilt. We’ll test yours and advise the most economical option.
-
Both use a flexible element, but diaphragm units are more compact and suited to smaller volumes, while bladder units handle larger flows and volumes. We’ll help you choose — see accumulator sizing.
-
Yes — we set and verify nitrogen pre-charge on diaphragm accumulators in-shop or on-site.
