JONSN MR SERIES PRECISION MINIATURE MAGNETIC GEAR PUMP
Solve an industry pain point in a single sentence: Achieves truly high-precision, pulse-free, and linearly stable delivery of flow rates at the milliliter level, while supporting fully customizable, non-standard adaptations
1.Ultra-high precision, consistent batch-to-batch quality.
Adopting the positive displacement volumetric principle and driven by servo/stepper motors, the equipment delivers pulse-free linear fluid output.
Linear Accuracy: ±0.5%
Repeatability: ±0.2%
Flow Rate Attenuation: Less than 2% after 10,000 hours of operation (industry average: ≤5% attenuation within 6 months)
Unit-to-Unit Delivery Accuracy: ±2%~±5% (conventional industry standard: ±5%~±10%)
Advantage: Significantly reduce equipment integration costs and subsequent calibration expenses.
2. Powerful Suction & High Pressure Resistance, Suitable for Extreme Working Conditions
Suction Performance: Maximum inlet vacuum of -95 kPa, compatible with low liquid level, high-viscosity media and long pipeline conveying
applications.Pressure Resistance: Standard pressure resistance up to 4 MPa; custom special models support high-pressure delivery ranging from 6 MPa to 10 MPa.
3. Zero Leakage, Safe & Sanitary
Equipped with full magnetic drive and static O-ring sealing structure to fully enclose media throughout the flow path.
Eliminates abrasion risks of mechanical seals, completely preventing medium leakage, material contamination and cross-contamination between materials.
Compliance Standards: Food-contact grade; FDA testing and certification; RoHS testing and certification (free of heavy metals).
4. Special Materials & Exquisite Craftsmanship
Gear Shaft: Made of high-strength modified PEEK, heat-treated and matched with zirconia ceramic, featuring outstanding wear resistance, corrosion resistance and stable dimensional performance without deformation.
Sliding Bush: Integrally molded PEEK-ceramic composite formula with low friction coefficient. Its wear resistance is 5 times that of ordinary bushes, enabling quiet and stable operation.
5. Ultra-long Service Life, One Unit Equals Three Ordinary Pumps
Dual optimization of structure and materials; over 20,000 hours of maintenance-free continuous operation.
Actual tested service life is 3–5 times that of conventional gear pumps on the market.
Reduces downtime, spare parts replacement and manual maintenance costs, improves continuous production line efficiency and boosts return on investment (ROI).
6. In-depth Custom Non-standard Solutions for Seamless System Integration
Full-dimensional customized development tailored to exclusive requirements of various equipment:
Port Customization: Full specifications including VCR, quick connectors, sanitary tri-clamps and more are optional.
Inlet & Outlet Orientation: Multiple directions of 0°/90°/180° to fit compact equipment spaces.
Surface Coating Customization: Electropolishing, PVD wear-resistant coatings available on demand.
Motor Integration: Servo / stepper motors; closed-loop flow control systems can be developed.
Mounting Types: Multiple fixing options such as flanges, brackets and embedded bases.
Extra Functions: Integrated flow feedback, temperature sensors, Modbus / CANopen communication protocols, etc.
From standard models to custom fluid transfer solutions, JONSN helps break technical barriers in precision micro-volume conveying.
