Pressure accumulators serve as an air reservoir in automation technology, as a pressure spring in mechanics, and as a power-free failsafe solution in safety engineering.
Our pressure accumulator solutions are based on industrially proven series components, offering not only the highest reliability and (unlike welded solutions) particle-freeness, but also a significant price advantage — up to 50 % cheaper than comparable products. Market leaders across a wide range of industries therefore rely on us.
At the same time, our in-house developments create extensive design freedom for engineers — technically flexible and economically efficient.
Price advantage through standard industrial components
30–50 % cheaper
than dedicated pressure accumulator systems — the advantage of mereco pressure accumulators over conventional pressure accumulators.
By design
100 % particle-free
No weld residues — unlike welded pressure accumulator solutions.
Fundamental advantages of pressure accumulators when redesigning pneumatically operated equipment:
01
Constant working pressure
Working pressure is available permanently and constantly; load changes of the compressor/pump are buffered.
02
Optimal operating range
The compressor/pump can run in its optimal operating range and is not constantly switched on and off as needed or briefly overloaded. This increases both the efficiency and the service life of the system.
03
Lower noise level
The compressor does not need to start up for every working pressure demand. Occasional, continuous noise phases are far less disruptive than frequent, impulse-like noise events.

Pulsation Dampers
Why use pulsation dampers?
Pulsation dampers are a special form of pressure accumulator whose special design provides highly effective damping of pressure fluctuations in pneumatic systems.
Their use is particularly advantageous with powerful piston compressors, which often cause significant pulsation during pressure build-up. These pressure fluctuations can impair precise control processes and measurements.
Through highly effective suppression of pulsation amplitudes, pulsation dampers not only reduce the noise emission of the entire system but also ensure trouble-free operation of controls and measuring devices. Sensitive sensor data is not overlaid by high interference levels, significantly simplifying the evaluation of measurement results.
In addition, they are cost-effective and simultaneously act as efficient pressure accumulators, ensuring a continuous flow of pressure.
Reduced disruptive noise
up to 15 dB
Highly effective suppression of pulsation amplitudes — more than 12 dB already in the standard version, up to 15 dB depending on the variant.
Especially valuable in medical technology
Another significant advantage is the marked reduction of disruptive noise in the overall system — especially valuable for devices in regular working environments or in medical technology, particularly for devices operating at a patient's bedside at night.
Typical problems without pulsation damping
Impairment of sensitive precision sensors and actuators
Pulsating pressure flow in the lines

The Basics
What is the difference?
Both components initially serve as intermediate storage for compressed air or vacuum in automation technology. Nevertheless, there are decisive differences in their function and application.
Pressure Accumulator
Basic functions
Permanent provision of working pressure
Constant working pressure, largely independent of compressor load
Safeguarding: working pressure for emergency triggering during a power outage
Protects compressors by avoiding constant alternating loads for short-term demand
Noise reduction through less frequent and more even use of compressors
Pulsation Damper
Use in sensitive applications
Pulsation dampers additionally take on the task of drastically reducing pressure fluctuations in the system. This is particularly relevant for piston compressors, as they tend to produce an irregular, strongly pulsating pressure flow due to strong pulsation, especially during pressure build-up, which can disturb sensitive components such as dosing devices, actuators or measuring equipment.
In such cases — e.g. for dosing tasks or precise measurements — pulsation dampers are the best choice. Installed in-line between pump and actuator, they act as a combined pressure accumulator and damper. Already in the standard version, a pulsation damper reduces the pressure amplitude by more than 12 dB. Depending on the application, variants with even higher damping performance are available.
Why not always use pulsation dampers?
Higher production effort leads to a higher price
Additional connection and therefore increased installation effort
With non-dehumidified compressed air, pulsation dampers tend to form condensate — this must be taken into account when designing the system
