CORE MANUFACTURING COMPETENCIES & METROLOGY

Standardized Mass Production
Precision gear pumps manufactured at scale with consistent accuracy and stable quality. Fast delivery and reliable supply ensure dependable support for large-volume project requirements, achieving a repeat purchase rate of up to 86.5%.

Material Delivery Without Pulsation
Precision grade gears feature high overlap geometry designs, meticulously molded and heat-treated using premium imported wear-resistant PEEK to maximize the elimination of micro-thermal deformation.

High Consistency & Repeatability
Transmission shafts adopt 100% high-strength nano-zirconia structural ceramics. All critical machining tolerances are held within ±2 μm to deliver ultra-stable long-term operational consistency.

High Strength & Leak-Free Technology
Magnetically driven leak-free design integrated with sliding bearings formulated from a confidential modified PEEK-ceramic recipe, delivering a verified system pressure resistance up to 6-10MPa.

Verified Long Service Life
The overall lifespan is verified to be more than three times longer than traditional gear pumps. Geometric tolerances are fully certified by onsite German ZEISS Coordinate Measuring Machine (CMM).
16 years of refinement - JONSN commands the full precision process: PEEK gears, PEEK bushings, PEEK heat treatment and assembly clearance control.
