Five in to One

Tekna Series is the range of innovative electronic metering pumps that SEKO has designed following many years of experienceworking with its customers world wide. These multifunctional metering pumps maintain outstanding precision and reliability, criticalto any customer, characteristics synonymous with the SEKO name.

Five Models that cover 0,4 to 110 l/h with an outputpressure up to 20 Bar

One Casing allows skids to be pre-constructed, as thefixing points remain constant, and the pumps can beselected on confirmation of the dosing flow

PVDF Pump Head and ceramic ball valve asstandard< PVDF is suitable for almost all chemicals used in Industrial,

Waste Water Treatment and potable Water applications.

< Ceramic balls are used to ensure chemical compatibilityand pump reliability.

The parts that make contact with the injected chemicalshave been chosen to provide precise compatibility withmost chemicals used in industry.

Long life diaphragm tested to give 5 yearsworking life< The advanced design and manufacturing process allows

the diaphragm to have a unique life expectancy.

< Made entirely of PTFE, the diaphragm is compatible withmost chemicals.

< Routine diaphragm replacement is no longer arequirement

Steady Dosing PerformanceStabilized Multi Power Supply 100÷240 Vac 50/60 Hz withreduced consumption< Reduced power consumption as the solenoid only draws

the required power to activate the pump, based on theworking conditions

< Stable dosing performance: improved pump efficiencyas performance is not affected by power supplyfluctuations
