Twin-Screw Pump
The MK FLOW Twin-Screw Pump is a high-performance positive displacement pump designed for viscous, volatile, multiphase, or shear-sensitive fluids. With its non-contacting intermeshing screw design, it offers pulsation-free, smooth flow, making it ideal for critical process applications in food, chemical, oil & gas, cosmetic, and pharmaceutical industries.
It is capable of handling both low and high viscosities, and can even run dry for short durations, making it extremely versatile.
⚙️ Working Principle
Twin-screw pumps use two precisely machined screws that rotate in opposite directions within a closely fitted housing. The intermeshing screws form chambers that trap and move fluid axially from suction to discharge side. Since the screws don’t touch, the design offers low shear and gentle fluid handling, with excellent suction capabilities and no pulsation.
