Available materials for metal dampeners are aluminium and stainless steel.
Aluminium dampeners
The aluminium dampeners are perfect to use for pH-neutral fluids. They have great resistance to corrosion and deterioration. They can be found in many applications from workshop, through paint industry to chemistry.
AISI 316 stainless steel dampeners
Dampeners made of stainless steel offer great mechanical strength combined with good chemical resistance. AISI 316 is resistant to aggressive and abrasive liquids. The dry part of the dampener that does not come into contact with the pumped product is, as a standard, made of corrosive resistant PP.
ATEX certified dampeners
The dampeners are available in explosion proof – ATEX marked – execution. They are supplied with earth connection and conductive materials: conductive body, diaphragm in PTFE (conductive backing) or EPDM (conductive).
Industry | Example of application |
Workshop | Oil, fat, solvents, water, cooling fluid, lubricants |
Print & paint | Glue, additives, varnish, ink, paint, latex, acid, resins, pigments |
Mining & construction | Adhesives, sump, dewatering, coal sludge, pastes |
Ceramic industry | Abrasives, glaze, water, enamels, clay |
Chemistry | Acids, alkalis, alcohol, solvents, latex, emulsions |
Aluminium for thick and thin pH neutral liquids. Stainless steel for chemicals.
