SINOR combines a National High-tech Enterprise qualification with 10+ years of custom engineering experience to push progressive cavity pump performance — from energy-saving stator geometry to precision metering accuracy.
Our in-house R&D team designs around real operating conditions — media viscosity, solids content, pressure stage, and uptime requirements. Every geometry, elastomer compound, and seal configuration is selected and verified on our own test benches before it reaches production.
We hold dual certifications as a National High-tech Enterprise and a Specialized, Refined, Distinctive & Innovative SME, and we hold multiple patents covering pump structure, seal systems, and precision dispensing technology.
Uniform-thickness stator geometry reduces friction and drive load, cutting energy consumption while keeping volumetric efficiency high.
Combined with the equal-wall stator, hollow rotor designs further reduce mass and inertia for quieter, more efficient operation.
Built-in agitator prevents bridging and arching of high-viscosity, fibrous, and lumpy media — smooth feed, no clogging.
Progressive cavity geometry delivers pulse-free, linear flow control — dosing accuracy within ±1% for chemical and polymer metering.
Multi-stage cavity design delivers stable output from 6 bar (single) up to 48 bar standard — and 60+ bar on custom builds.
Single/double mechanical seal and packed gland solutions engineered per media — sealing system optimization as a full technical package.
Media properties, flow, pressure, and site conditions are reviewed with the customer before any design work begins.
New geometries are modeled in CAD; OEM parts are replicated from samples or drawings using 3D scanning.
Prototypes are machined and run on our test benches — flow rate, pressure, vibration, and temperature all verified.
Approved designs move to the 15,000 m² production line with full material and batch traceability.
