1) The roughness of the surface in contact with the medium, including the sealing surface of the flanges (all standards), made of Hastelloy C, Monel or
Tantalum is Ra 0.8 μm. Lower surface roughness on request.
2) Housing weight see ä 51
3) Combination of AISI 316 for required pressure resistance and AISI 316L for required chemical resistance (dual rated)
4) ECTFE coating on AISI 316L.
When operating in hazardous area, avoid electrostatic charge of the plastic surfaces.
