TD_KN0_SS_rev.2.2 1 of 4 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 working conditions. General Specifications: „h Low noise integral gearbox, worm type, oil bath lubricated „h Reduced energy consumption based on low friction rolling bearings design „h High flexibility multiple mechanism solution to permit different piston speeds (SPM) on the same group „h Micrometric stroke lenght adjustment both manually and/or automatically actuated. „h Automatic stroke length variation by electrical servomotor, pneumatic actuator or frequency converter. „h Linearity and repeatability in compliance with API 675 Standards. „h Easy “on field” installation of electrical servomotor on manual stroke adjustment mechanism.
