Teffiko has been engaged in the R&D and manufacturing of industrial screw pumps for more than 20 years, focusing on delivering efficient and stable fluid‑transfer solutions for global industrial scenarios. The brand’s continuously‑variable speed screw pump (CV screw pump, Continuously Variable) is an upgraded precision positive‑displacement transfer device. It targets and addresses the industry pain points of conventional fixed‑speed screw pumps, namely fixed flow rate, poor adaptability and high energy consumption. Built on proven CV continuously‑variable transmission technology, the equipment enables stepless and jitter‑free continuous flow regulation, featuring high transmission efficiency and broad medium compatibility. It is widely applied in variable‑rate transfer working conditions for viscous materials across industries including chemical, environmental‑protection, food and daily‑chemical sectors.
The core principle of CV continuously‑variable speed relies on two sets of variable‑diameter gears or pulleys. The transmission ratio is dynamically adjusted via belt or chain drive to achieve continuous and stable speed regulation. Through technical iteration, the improved CV structure can bear a maximum torque of 300 N·m, which thoroughly breaks the torque limit of conventional small‑torque designs and fully meets the heavy‑duty operation requirements of industrial pumps.
The continuously‑variable speed screw pump adopts a core assembly of motor plus continuously‑variable gear gearbox. Leveraging the precise linear relationship between screw‑pump rotational speed and flow rate, it accurately controls output flow through smooth speed adjustment. Meanwhile, the rotor‑stator meshing forms closed volume chambers, ensuring pulse‑free medium transfer and stable pressure for superior transfer performance.
Featuring compact layout and easy disassembly for maintenance, the pump consists of four core modules: the CV continuously‑variable transmission mechanism acts as the speed‑regulation core to guarantee smooth speed change and low transmission loss; wear‑resistant and corrosion‑resistant rotor‑stator assemblies adapt to complex media that are viscous or contain particles and impurities; high‑strength sealed pump body effectively prevents medium leakage; optimized inlet‑outlet flow channels deliver excellent self‑priming performance for stable transfer of high‑viscosity materials.
At present, mainstream industrial models fall into two categories to match diverse production requirements. The mechanical CV gear speed‑regulation version adopts manual hand‑wheel speed adjustment. Requiring no electronic control, it features low failure rate and high cost‑performance, suitable for conventional manual‑operation production conditions. The frequency‑conversion continuously‑variable speed version is equipped with an intelligent frequency converter, supporting remote control and automatic pressure‑and‑flow stabilization. It provides higher speed‑regulation precision and fits fully‑automatic production lines and dynamically changing working conditions.
Compared with ordinary screw pumps, the CV continuously‑variable speed screw pump boasts remarkable strengths. Free of shift jitter, it delivers uniform and stable flow output and strong process adaptability. Its transmission efficiency reaches 95 %, far exceeding the 85 % of ordinary automatic transmissions, delivering prominent energy‑saving effects and fast response. It is compatible with various viscous liquids as well as media containing fibers and fine particles for wide application coverage. In addition, smooth speed adjustment reduces mechanical impact, extends service life and lowers overall operation‑and‑maintenance costs.
Focusing on variable flow regulation and stable transfer of viscous materials, the equipment serves key working conditions in multiple industries: in environmental‑protection industry, it transfers sludge, flocculants and viscous sewage; in food and daily‑chemical industry, it handles pasty materials such as honey, sauces, toothpaste and lotions; in chemical industry, it conveys coatings, lubricants and corrosive slurries. It also applies to precision‑production scenarios such as quantitative feeding for light‑industry and pharmaceutical sectors as well as industrial slurry transfer.
With mature CV continuously‑variable transmission technology, the continuously‑variable speed screw pump fundamentally resolves the pain points of conventional pumps including fixed flow rate, high energy consumption and weak medium adaptability.
