Nexa Series includes plunger and hydraulic diaphragm dosing pumps designed in compliance with API 675 Standards; the conformity to the API Standards implies a “heavy duty” design, high safety and severe controls of the performances during the tests. The broad variety of heads execution offers a wide selection of dosing pumps to cover practically any application needs. In addition the full compliance with the ATEX European Directive gives the possibility to install these pumps in classified areas too.*

Mechanism
Available in different sizes, they are mechanical return type, giving the maximum reliability in all the conditions.
