Reproducible dosing precision of ± 2 %
Stroke length manually adjustable between 0% and 100%
Also suitable for frequency converter operation
Wide range of dosing head materials
With ATEX certification can be used in zones 1 and 2 explosion risk areas
Non-leaking
Suitable for highly aggressive or poisonous dosing media,
Intermediate chamber for targeted discharge of the dosing medium in the event of a diaphragm rupture

The MEMDOS LB dosing pump with ATEX certification is an electric motor-driven, explosion protected of equipment group II, equipment category 2G. When used with an explosion-protected motor, it is used to supply and dose fluids in zone 1 and 2 explosion risk areas.
