A stable and reliable pressure circuit is essential for accurate long-term hydrostatic pressure testing of plastic pipes and fittings. AHP PLASTIK MAKINA has developed a new 4-liter diaphragm accumulator specifically for use in hydrostatic pressure testing systems.
The accumulator is designed to help stabilize system pressure, absorb pressure fluctuations, reduce hydraulic pulsations, and protect pressure circuit components during continuous testing.
With its stainless steel 304 lid construction (Parts in contact with water), Italian diaphragm, powder-coated steel body, standard M28×1.5 connection, and integrated metal protection filter, the accumulator provides a durable solution for demanding laboratory and industrial testing applications.

Stainless Steel 304 Lid Construction
Since the accumulator is continuously exposed to water during operation, the top wetted section is manufactured from Stainless Steel 304.
The use of stainless steel significantly improves corrosion resistance and helps prevent deterioration of the internal surfaces during long-term operation.
This is particularly important in hydrostatic pressure testing equipment, where the accumulator may remain connected to a water circuit for extended periods.
Durable Powder-Coated Steel Body
The external body is manufactured from steel to provide the mechanical strength required for demanding pressure testing applications.
A durable powder-coated finish protects the external steel surfaces against environmental conditions while providing a professional industrial finish.
The combination of a strong steel body and corrosion-resistant stainless steel internal components provides both mechanical durability and long service life.
High-Quality Italian Diaphragm
The diaphragm is one of the most critical components of an accumulator.
For this design, AHP PLASTIK MAKINA uses a high-quality Italian diaphragm selected for reliable operation under repeated pressure cycles.
The diaphragm separates the working sections of the accumulator and responds continuously to pressure changes in the hydraulic circuit. Its quality therefore has a direct influence on pressure stabilization, reliability, and service life.
Standard M28×1.5 Accumulator Connection
The accumulator is equipped with a standard:
M28×1.5 mm connection
Using a standardized accumulator connection simplifies installation, servicing, and integration into hydrostatic pressure testing systems.
Integrated Metal Filter for Diaphragm Protection
An important feature of this accumulator is the integrated metal filter located in the fluid path before the diaphragm.
During operation, small particles, machining residues, contamination, or other debris may circulate within the water system. If these particles reach the diaphragm, they can cause premature wear or physical damage.
The metal filter helps prevent contaminants and solid particles from entering the diaphragm area, providing an additional level of protection and helping extend diaphragm service life.
Serviceable Stainless Steel Top Cover
The accumulator is designed with a removable stainless steel top cover secured by stainless steel bolts.
A dedicated central service opening is provided in the stainless steel cover.
This serviceable construction provides convenient access to the internal components when inspection, diaphragm replacement, or maintenance is required.
Why Is an Accumulator Important in Hydrostatic Pressure Testing?
Hydrostatic pressure testing systems are required to maintain controlled pressure conditions for extended periods.
Pump operation, valve switching, temperature variations, and changes within the hydraulic circuit can create small pressure fluctuations or pulsations.
The accumulator acts as a hydraulic energy buffer, absorbing sudden pressure variations and releasing stored energy when required.
As a result, it can contribute to:
- Improved pressure stability
- Reduced pressure pulsation
- Smoother operation of the hydraulic circuit
- Reduced stress on pumps, valves, fittings, and other components
- Improved reliability during long-duration pressure testing
