Hydraulic Diaphragm Pumps – Seko Tork/Stark

Tork/stark are designed according to the API 675 standards. Tork is hydraulic double diaphragm pump; Stark is hydraulic single diaphragm pump.

Tork
SEKO’s long standing experience of designing and producing pumps for heavy duty applications has been utilized for
the design of the Tork series. It offers an outstandingly flexible pump configuration allowing for customization of the
pump even post installation whilst remaining always easy to maintain.

• Capacity range: up to 2065 l/h, up to 200 bar
• Wetted parts: SS 316L, PP, PVDF and PTFE
• Certified ATEX 94/4/CE II 2 G E IIB T4 (for Zone 1)

Designed to produce low noise emissions and to minimize power consumption. Each mechanism comes complete with an internal gearbox; pumps with different speeds(strokes/min) can therefore be joined, allowing for 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 electrical 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. Manages solid suspensions thanks to the diaphragm not requiring perforated shields on the process side, which allows liquids containing solid suspensions to be pumped.

Stark
The Stark series are hydraulic diaphragm dosing pumpssuitable for applicationsthat require very high levels of precision, manufactured with materials that ensure compatibility with the widest range of liquid dosing application.

• Capacity range: up to 660 l/h, up to 124 bar
• Wetted parts: SS 316L, PP, PVDF and PVC

Conceived to produce low noise emissions and to minimize power consumption. High precision stroke adjustment, both manual and via electric actuator. Other design features include a zero-leakage profile offering watertight construction for dosing toxic, corrosive and other hazardous liquids; it also offers protection against pollutants which could contaminate the liquid that is being pumped.

The flow rate adjustment uses SEKO’s AKTUA system that replaces the pump’s manual flow adjustment device with an automatic system that offers remote management. A mechanical refilling system maintains a constant hydraulic fluid level, thereby guaranteeing maximum precision and repeatability. It also helps manage the eventual deformation of diaphragm thereby increasing its lifespan and reducing operational costs.

Applications
Urban water plant, waste water treatment, industrial waste water and various chemical, etc.
