Tork Series

SEKO’s years of experience in designing and manufacturing pumps for long-life applications were used to design the Tork series. It offers an exceptionally flexible pump configuration that allows the pump to be installed even after installation, while remaining easy to maintain at all times.

The Tork Series is designed to produce low noise emissions and minimize power consumption. Each mechanism comes with a built-in gearbox; Therefore, pumps with different speeds (strokes / min) can be combined, giving greater flexibility in choosing the pumps themselves. High precision stroke adjustment with precision level ±1%, both manual and adjustable using SEKO designed electric actuators.

Other features include a zero leak profile offering waterproof construction for dosing toxic, corrosive and other hazardous liquids; The double diaphragm protection system immediately reports the pump’s unstoppable abnormality, thus avoiding immediate downtimes.

Tork is also able to manage solid suspensions thanks to the diaphragm, which does not require perforated shields on the process side, allowing liquids to be pumped into solid suspensions.
