SEKO Hydraulic Double Diaphragm Dosing Pump with Diaphragm Rupture Alarm Device

Nexa series SEKO hydraulic double diaphragm dosing pump are designed and manufactured in accordance with the API675 Standard, and are divided 3 sub-series: YN, TN, and HN. The dual-diaphragm design provides double safety protection for both the pump body and the system.

The pump features a built-in mechanical automatic oil refill system to ensure a constant hydraulic oil level, thereby achieving high linear accuracy and repeatability while effectively controlling diaphragm deformation and extending its service life. In addition, the Nexa dosing pump is equipped with an electronic regulator that replaces the traditional manual flow adjustment mechanism, enabling automatic stroke regulation to meet the demands of modern production for precise dosing and remote control.
