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.

  • ± 0.2 %
    Repeatability
  • > 20000 h
    Flow rate degradation: 2% (10,000 h)
  • ± 0.5 %
    Linearity accuracy
  • 3-5 x
    Exceeds industry lifespan
  • 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.

  • 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.

  • 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 21 CFR 177 compliant (food contact); RoHS testing and certification (free of heavy metals).

  • 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.

  • Ultra-long Service Life, One Unit Equals Five 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).

  • 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.

    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.

High-quality Machining
How JONSN Standardizes MRA Multi-Order Volumetric Reproducibility? Clearances locked via world-class CNC centers, 100% full-process certified via premium Dutch-imported mass flow meters.
Onsite Heavy Machining Infrastructure
MRA series micro-casings and ultra-clean fluid blocks are flawlessly carved by onsite Japanese Mazak Multi-Axis CNC Machining Centers and Tsugami CNC lathes. Clearance boundaries are rigidly locked within micro-levels using automated plane lapping to eliminate manual deburring errors and random hand-fitting variance, steering the volumetric efficiency of the two-stage sealed shell toward perfection.

FAQs aboutMRB Micro Gear Pump & 400-4800ml/min

How does JONSN MRB series ensure pulse-free linear delivery as a high-efficiency chemical dosing pump platform?

High-pressure reciprocating plunger or legacy diaphragm pumps generate violent fluid transient pulses and transient pressure fluctuations, causing ununiform chemical blending. JONSN MRB micro gear pump adopts a positive displacement volumetric principle d

How does this precision micro gear pump achieve zero leakage when handling highly aggressive polar chemistry solvents?

Conventional gear pumps with standard dynamic seals or mechanical joints experience rapid localized internal leakage and wear when processing highly corrosive fluids. JONSN MRB integrates a static magnetic sealing design with static O-ring housing structu

Can the JONSN MRB micro leak-free pump platform withstand continuous high system process counterpressures up to 25 bar?

Yes. As verified in our official technical reference curve sheets, the MRB series features an elite pressure resistance capacity withstanding up to 25–30 bar differential pressure and 4 MPa static pressure capacity. Engineered with premium imported wear r

What non-standard deep custom development solutions can JONSN provide on the MRB line for automated system integration?

JONSN provides full-dimensional non-standard deep custom development for seamless integration into various industrial skids. This includes flexible port selections (VCR semiconductor joints, heavy-duty chemical flanges, quick connectors, sanitary triclamp
