Overview

Nexa PN is designed according to the API 675 standards. The use of various high grade materials during construction allows these metering pumps to satisfy every liquid dosing and mixing application, including hazardous areas given their compliance also to the ATEX European Directive.

Designed to produce low noise emissions and to minimize power consumption. Each mechanism comes complete with an internal gearbox allowing different pumps to be added together to form multi head pump units, providing greater flexibility in selecting the pumps themselves. Its high precision stroke adjustment, to an accuracy level ± 1%, can be both manually or electrically adjusted using SEKO designed pneumatic actuators. 

Other features include a zero-leakage profile offering watertight construction for dosing toxic, corrosive and other hazardous liquids; its double diaphragm protection system immediately signals the anomaly whilst not stopping the pump from working, thereby preventing immediate downtime.
