The initial feed rate reproducibility is ±10 %.
As the metering hose loses elasticity the feed rate can fall over a
period in operation (see also "Maintenance").

The device is resistant to normal atmospheres in technical areas.
The metering hose is resistant to the following at 25 °C:
- Chlorine beaching solution 12 % (NaOCl) (only Tygon
- Sodium hydrogen sulfate 15 % (NaHSO
- Hydrochloric acid 38 % (HCl) (only Tygon
- Sulfuric acid 30 % (H SO
2
- Organic chlorine products 10 % (Chlorifix) (only Tygon
- Polyaluminiumchloride (PAC)
For the resistance to other chemicals, see the ProMinent list of
compatibilitys (homepage or products catalog).
The device must not be placed in the direct path of UV radiation.
