Beverage production relies on precise fluid proportioning. A single beverage formula may contain more than 10 components including syrup, acidity regulators, flavors, colorants, fruit puree and plant protein liquid. Minor dosing deviations can be easily detected by consumers: a ±1% syrup variation alters sweetness, a ±0.5% flavor shift changes the taste profile, and a ±0.2% colorant discrepancy leads to inconsistent hue between bottles. Meanwhile, beverage production lines impose stricter standards for sanitation, CIP compatibility and product changeover efficiency than general industrial processes.
Equipped with ±0.2% repeat accuracy, leak-free full magnetic drive and food-grade materials (316L stainless steel + PEEK + FFKM), JONSN MR Series micro magnetic gear pumps deliver a complete precision fluid solution covering syrup blending through plant protein filling.
A beverage consists of water, syrup, acid, flavor, colorant and other ingredients. Flavors may account for as low as 0.05% of total volume, while colorants are dosed at merely tens of ppm. Conventional metering pumps generate pulsation and repeatability errors at such tiny flow rates, resulting in inconsistent flavor between batches. Uniform taste is an irreplaceable core competitive advantage for beverage brands.
Syrup viscosity reaches thousands of mPa·s, and plant protein slurries are even thicker. Screw pumps and centrifugal pumps suffer drastically reduced efficiency and excessive heat generation when handling high-viscosity fluids. High shear force breaks the molecular structure of plant proteins, causing sedimentation, layer separation and grainy texture. Intact protein structure is the core selling point of plant-based drinks.
Carbonation requires precise water flow metering under backpressure. Flow pulsation from supply pumps triggers pressure swings inside carbonation tanks, destabilizing CO₂ dissolution. This creates inconsistent carbonation levels across batches, with some drinks flat and others prone to overflowing when opened.
Beverage lines may switch between 3–5 product variants (different flavors or series) daily. Conventional pumps feature complex internal structures and large dead volumes, extending CIP cleaning time and water consumption. Residual syrup trapped in dead spaces breeds microorganisms within 4 hours at ambient temperature, posing critical food safety hazards.
High-fructose and cane sugar syrups range from 100 to 5000 mPa·s, with viscosity varying sharply with temperature and concentration. The MRA Series (100–2000 mL/min) delivers steady volumetric flow via positive displacement design: flow remains nearly unchanged at fixed rotation speed even if syrup temperature rises from 20°C to 40°C and viscosity drops by half. Paired with the MPG Series (40 μL/r) for micro-injection of acidity regulators (citric/phosphoric acid solutions), the sugar-acid ratio is locked within ±0.5% of the formula target, enabling fully reproducible base syrup taste parameters across batches.
Recommended: MRA (main syrup supply) + MPG (micro acid injection)
Flavors are typically dosed at 0.05%–0.5% (500–5000 ppm), while colorants range from 10–100 ppm. The MPG Series (40 μL/r displacement, 1–280 mL/min flow) adopts continuous multi-tooth meshing to achieve truly pulsation-free micro continuous injection, unlike the intermittent surging output of diaphragm pumps. Smooth delivery similar to intravenous infusion evenly disperses flavor and color molecules into the main stream, eliminating uneven taste and color across sips. Multiple MPG pumps can be installed in parallel with independent delivery and metering for each flavor/colorant.
Recommended: Multiple MPG units, independent channel per flavor/colorant, ppm-level precision
Carbonation dissolves CO₂ into water under backpressure. The MRA Series delivers precisely metered degassed water to carbonation tanks. Pulsation-free positive displacement flow stabilizes tank pressure fluctuation below ±0.5%, ensuring consistent CO₂ solubility across all batches. Full magnetic sealing prevents ingress of ambient air, avoiding re-oxygenation of degassed water that impairs carbonation efficiency. Carbonation volume deviation is controlled within ±0.1 vol.
Recommended: MRA Series (100–2000 mL/min), pulsation-free water supply for stable carbonation
NFC (Not From Concentrate) juice contains pulp fibers and natural pectin, with viscosity of 50–500 mPa·s and acidic pH (orange juice pH 3.3–4.2). MRA Series pump heads constructed from 316L stainless steel resist acidic juice corrosion. Wide flow channels of positive displacement gear pumps smoothly pass pulp fibers without clogging or crushing fruit cells, preserving the natural authentic flavor of NFC juice. Full magnetic sealing eliminates leakage and external contamination during raw juice transfer.
Recommended: MRA Series (100–2000 mL/min), acid-resistant 316L construction with pulp-friendly flow paths
Plant-based drinks including soy, oat and almond milk contain 1%–3% protein with slurry viscosity ranging from 2000 to 10000 mPa·s. The DP Series (0.2–100 cc/r), engineered for high-viscosity media, features low-shear gear sets that minimize damage to protein molecular chains — a performance unattainable by high-shear screw pumps. The MRA Series handles finished blended liquid transport to filling machines. The full-line low-shear design maintains suspension stability and smooth mouthfeel of plant protein beverages.
Recommended: DP Series (high-viscosity protein slurry) + MRA (post-blending transfer), low-shear design to preserve protein integrity

Syrup viscosity fluctuates drastically with temperature and concentration, yet pump flow is solely determined by rotation speed. No recalibration is required even if syrup temperature shifts from 20°C to 40°C; formula settings remain effective year-round.
Low-speed, large-displacement DP Series delivers minimal shear force, preserving nearly complete protein molecular chains during transfer. It eliminates graininess, layer separation and sedimentation — a critical texture benefit unachievable with high-shear screw pumps.
316L mirror polishing, FFKM seals and dead volume below 0.5 mL enable complete line switching after only 3 minutes of alternating CIP alkaline and acid cleaning. ATP swab test readings stay below 10 RLU to fully eliminate hidden food safety hazards.
Static O-ring seals replace dynamic mechanical sealing surfaces to eliminate all leakage points. It prevents syrup drips that attract pests and blocks external bacterial contamination — a fundamental requirement for food cleanrooms.
Five beverage categories with diverse fluid properties are fully supported: MRA handles syrup, raw juice and process water; MPG serves flavor and color micro-dosing; DP manages high-viscosity plant protein slurries. Beverage equipment manufacturers only need one supplier, JONSN, to resolve all fluid transfer demands.
