Product description

Full-PTFE diaphragm for standard accumulators
HYDAC has developed a full-PTFE diaphragm and has patented its design and application.
It is resistant to aggressive operating fluids and can be installed in almost all screw-type and weld-type standard diaphragm accumulators.

HYDAC thus revolutionizes the possible applications of hydraulic accumulators in the chemical industry, in process technology and also in water applications, such as on the pumps of drinking water treatment plants in marine applications.

Facts and figures:
- Nominal volumes up to 4 litres
- High level of media resistance
- Available for use in screw-type and weld-type diaphragm accumulators
- Rapid change-out of diaphragm possible (screw-type)
e.g. when required for repair or a change in operating media



The family of PVDF accumulators
HYDAC manufactures pulsation dampers completely made of polyvinylidene fluoride (in short PVDF) with a PTFE/ NBR diaphragm. Its principal component, PVDF, is a semi-crystalline thermoplastic and combines excellent chemical resistance (similar to PTFE) with good mechanical properties.

PVDF is hygienically safe. This makes it a suitable material for transporting water, dosing fluids (chlorine) and high purity fluids in the pharmaceutical and semiconductor industries.
Due to the high fluorine content of the PVDF, the HYDAC diaphragm accumulator pulsation damper is resistant to almost all fluids used in hydraulic systems and power units, and has universal applications particularly in metering technology and the chemical industry.

Facts and Figures:
- Nominal volumes. 0.08; 0.2 and 0,5 litres
- Max. permissible operating pressure up to 25 bar
- Diaphragm and accumulator shell are highly resistant to almost all operating media,
- Entire accumulator can be used for temperatures up to 60 °C
- PTFE and PVDF make these accumulators suitable for food industry applications
