Metering head materials offered
-
Polypropylene: Very price-worthy version, resistant to a high number of acids and brines. Typical application areas: water treatment applications
- Acrylic: High resistance against Sodium Hypochlorite and has the advantage that the metering process can be seen through the translucent dosing head. Trapped air or cristalline sediments can be recognized and removed.
-
PVDF: Resistant against concentrated and oxidizing acids and brines. Price-worthy alternative to PTFE.
-
PTFE: Especially suitable for the metering of high-concentrated and oxidizing acids and brines.
-
Stainless steel: Most suitable for the metering of solvents and oil-like fluids.
For strongly outgasing media ProMinent offers self-ventilating metering headsin PP and perspex.
This universally applicable pump generators an excellent cost/performance ratio. Either foot or metering valve - as per demand - being included in delivery.
