Tork Series

Summary

Product identification

The Tork series consists of hydraulic double diaphragm dosing pumps with full motion mechanisms. They feature mechanical return type mechanisms available in several sizes, designed for low noise emissions and minimized power consumption. Each mechanism includes an internal gearbox, allowing pumps with different speeds (strokes/min) to be joined.

Key features:

• High precision stroke adjustment, to an accuracy level ± 1%, manually or electrically adjusted.
• PTFE double hydraulic diaphragm heads (TY, TT, TH) for double protection and operational safety.
• Zero-leakage profile with watertight construction.
• Double diaphragm protection system signals anomalies without stopping the pump.
• Flow rate can be changed by replacing the plunger and relevant seal cartridge.
• Manages solid suspensions due to the diaphragm not requiring perforated shields on the process side.
• Mechanical refilling system maintains a constant hydraulic fluid level for maximum precision and repeatability.

Operating limits

• Flow rate: Up to 2065 l/h
• Pressure: Up to 200 bar
• Stroke adjustment accuracy: ± 1%

Feed water

These pumps are suitable for dosing toxic, corrosive, and other hazardous liquids. They can also manage liquids containing solid suspensions.

Electrical

• Motor power: 0.18 kW, 1.1 kW, 2.2 kW
• Stroke adjustment can be electrically adjusted using SEKO designed electrical actuators.
• Automatic flow rate variation is optionally available via electrical actuators AKTUA.

Mechanical / hydraulic

• Mechanism: Mechanical return type with internal gearbox.
• Pump head material: SS 316L, PP, and PVDF
• Stroke length: 10 mm, 25 mm, 35 mm
• Diaphragm diameter: 12 mm, 15 mm, 25 mm, 30 mm, 35 mm, 50 mm, 70 mm, 90 mm, 120 mm
• Valves: Cartridge valves with double and triple ball configurations for maximum dosing precision. Metal gaskets for SS316L heads and FPM gaskets for plastic heads ensure compatibility.
• Safety: Built-in relief valve protects against unexpected overpressure. Double diaphragm with rupture detector activates a local visual indicator or signal, allowing the pump to continue working while maintenance is scheduled.
• Venting: Automatic venting during operation, also facilitates pump priming via manual air purge.
