Applications

A progressive cavity pump uses a rotating rotor inside a flexible stator to create sealed cavities that move fluid continuously u2014 giving pulse-free, self-priming flow. Unlike centrifugal pumps, it handles high-viscosity fluids, shear-sensitive materials, and fluids with entrained solids or fibers. Unlike piston/diaphragm pumps, it produces constant flow at varying pressure without pulsation.

SINOR pumps serve 9 major industries: wastewater treatment, chemical processing, food & beverage, oil & gas, pharmaceutical, paper & pulp, mining, 3C electronics, and new energy (EV battery / solar). Each application page above explains the specific scenarios, challenges, and recommended pump series for that industry.

Start with your fluid: viscosity, solid content, temperature, and chemical compatibility. For general transfer: SGP Series. For food-grade sanitary: SFP Series. For high-viscosity or fibrous materials: SSP / STP hopper pumps. For metering & dosing: SMP Series. For precision dispensing (adhesives, thermal grease): SSV / SDJ Series.

Yes. Choose chrome-plated or tungsten carbide coated rotors and HNBR stators for abrasive slurries; Duplex 2205 rotors and FKM stators for corrosive chemicals. All stator materials (NBR, EPDM, FKM, HNBR) are available to match your media compatibility requirements.
