With a little assistance, many homeowners can replace a hydraulic accumulator membrane on their own. The hydraulic accumulator, which is frequently seen in hydraulic or heating systems, depends on a membrane to keep pressure constant and guarantee correct operation. This membrane may deteriorate or start to leak with time, which would lower system efficiency. Thankfully, changing the membrane is an easy procedure that can get your system operating again without requiring professional assistance.
It’s important to gather the required tools and materials before you start. Usually, you’ll need some simple tools like pliers or wrenches, along with a replacement membrane made specifically for your model of hydraulic accumulator. Before beginning work, it’s also imperative to make sure the system is securely isolated and depressurized. This keeps the pressure from accidentally releasing and guarantees your safety the entire time.
Find the hydraulic accumulator in your system first. It typically has a cap or access point that lets you reach the membrane, and it’s frequently connected to pipes. Using your tools, carefully remove the cover or cap once you’ve found it. It might take some force to complete this step, so take care not to harm any nearby components.
Once the cover is off, the old membrane will be visible. Observe the placement and fastening of the old membrane within the accumulator. Depending on the model, clips, screws, or other fasteners may be used to hold it in place. Remove the old membrane carefully, being cautious not to damage any internal fixtures or components.
Next, make sure the new membrane is compatible with your hydraulic system and meets the specifications of the old one. Correctly align the replacement membrane in accordance with the manufacturer’s instructions or any internal accumulator markings. Using the proper fasteners, firmly but not too firmly, ensure that it is in place to prevent damage.
Once the new membrane is firmly in place, put the hydraulic accumulator’s cap or cover back on. Using your tools, firmly tighten it, making sure it’s properly sealed to stop any leaks. Following the manufacturer’s instructions, you can then gradually reintroduce pressure to the system after everything has been put back together.
Lastly, once the pressure has been restored, look for any indications of leaks or strange behaviors in the system. You’ve successfully replaced the hydraulic accumulator membrane on your own, saving time and money by doing it yourself rather than hiring a professional if everything seems to be working properly. For many years to come, the smooth operation of your hydraulic system is ensured by routine maintenance and prompt replacement of parts like membranes.

How to determine a breakdown
While traveling to the location, I discovered that the gadget was bought four years prior. Furthermore, the neighbor permanently resides in the country. This indicates that enhanced mode is being used by the water supply system. Although the accumulator membrane is intended to last five years, it breaks much sooner when subjected to continuous loads.
If you push it to work hard, the temperature will rise and the pressure will start to drop because of the frequent compression. However, the membrane material is not fond of it. Rubber can only withstand temperatures up to +70 °C, after all. It starts to crack at higher temperatures.
If you notice a regular drop in the water pressure, you should become very concerned. Furthermore, these are unmistakable indicators of major issues when the pump runs too frequently. However, these phenomena might point to tank issues. Maybe there was a crack in it. You will also need to disassemble the device in order to determine whether the membrane in the storage tank needs to be replaced.
It will become evident right away during disassembly whether there are issues with the rubber pear. The tank is actually divided into two segments that are totally isolated from one another. One of them contains water, and the other one contains air. Furthermore, if the atmosphere starts with the fluid from the tank as well, a membrane rupture occurred.
The entire pear will never allow these two settings to coexist. And once everything is in order, you have to drain the water and then steal the air. It won’t be feasible to enter the structure and perform a thorough diagnostic until then. However, it is essential to cut the hydrophore off from the water supply before performing this kind of check.
The following video will demonstrate how to inspect the hydraulic accumulator and determine whether the membrane needs to be replaced:

Only after the water has been totally drained and the air has been bled out of the tank can the membrane be removed. To expel the atmosphere, the body has a unique nipple. You must unfasten the lid’s fasteners and disconnect the hose in order to empty the water.
Let’s examine the step-by-step process for replacing a hydraulic accumulator’s membrane:
- The unit is disconnected from the water supply and taken out into the open space.
- Air is released through the nipple.
- The hose is removed.
- The screws on the cover are unscrewed halfway to drain the water.
- After all the liquid has drained, remove the cover with the pressure gauge.
- The membrane is removed through the technological hole.
- The pear is washed from dirt and rust and carefully inspected. If it has become unusable, then a new membrane is prepared.
- The tank is thoroughly washed and dried. Then checked for possible defects.
- The membrane, selected according to the capacity of the container, is mounted in its place.
- 10.The structure is reassembled in reverse order.
In order to install a membrane in a hydraulic accumulator, no particular training or expertise is needed. The only thing left to do is to make sure the hydrophore is operating properly. It must be reconnected to the water supply, and you must pump in up to two atmospheres of air. Using a unique spool, a standard pump can accomplish this.
Water is then added to the tank. However, you must proceed cautiously to avoid damaging the membrane. It is preferable to use the least amount of pressure and to hold off until the container is full.
The following are the key elements in hydraulic accumulator prevention. The tank body is inspected for damage once every three months. Additionally, the pressure level is checked every six months. The pressure gauge and pressure switch are also checked for proper functioning at the same moment.

Although replacing a hydraulic accumulator membrane may seem difficult, it is a task that can be completed with the correct equipment and a methodical approach. First, make sure you’re safe and gather the required supplies, which include a wrench, a new membrane, and maybe a pressure gauge. Release the hydraulic system’s pressure before starting to prevent mishaps.
After the system has been safely depressurized, find the accumulator and use your wrench to carefully disassemble it. Make a note of the old membrane’s placement and carefully remove it to prevent accumulator housing damage. To guarantee a good seal with the new membrane, clean the housing of any dirt or leftover sealant.
Next, install the new membrane by cautiously inserting it into the accumulator housing in accordance with the guidelines provided by the manufacturer. Ensure that it fits snugly and flush inside the housing. To stop leaks, reassemble the accumulator and evenly tighten the bolts. After assembly, gradually repressurize the hydraulic system while keeping an eye out for any leaks or unusual pressure fluctuations.
You are done replacing the hydraulic accumulator membrane after making sure the accumulator is operating properly and there are no leaks. Hydraulic systems require routine monitoring and maintenance in order to function effectively and last a long time. You can confidently take on similar maintenance tasks in your construction or repair projects by following these guidelines and exercising caution.
