Recently, a major domestic tobacco industry customer completed the domestic substitution of key equipment in its low-flow flavor delivery process: the JONSN MRA series magnetically driven precision gear pump replaced a gear pump from a European and American international brand originally in service. At a working condition of 4 bar pressure and 0.8 L/min flow rate, the pump achieves stable, precise and leak-free delivery. Both operational stability and service life match or exceed the original imported solution — yet another field-proven case supporting JONSN's proposition that its products can fully replace European and American imports.

▼ Customer Background: The Hidden Costs of Costly Reliance on Imported Pumps

The customer originally used a magnetically driven gear pump from a European and American international brand, configured with a 316 stainless steel pump body, PEEK gears on 316 shafts, PTFE seals, and a seal-less magnetic drive for zero leakage. In the initial stage of production, the seal-less zero-leakage design did indeed meet the sealing requirements of the flavor medium. However, as the production line ran over the long term, hidden problems gradually emerged:

• Core precision components had long depended on imports from the original manufacturer, with long spare-parts lead times, high unit prices, and weak localized technical service response;

• After long-term operation in the flavor medium, the gears and sealing components wore faster and precision degraded noticeably, so actual service life fell well short of expectations;

• The combined effect of these problems was more frequent unplanned downtime and flow fluctuation in flavor delivery between batches, directly affecting formula consistency and flavor stability, while annual maintenance and spare-parts costs remained persistently high.

  
  

▼ JONSN MRA: Proprietary Core Technology Redefines Low-Flow Fluid Transfer

Faced with the pain points of high operating costs and precision degradation of the imported pump, the customer ultimately selected the JONSN MRA series magnetically driven precision gear pump. Built on JONSN's proprietary core fluid transfer technology, the MRA series delivers systematic upgrades across three dimensions — materials, structure and medium compatibility:

Key Materials Upgrade: From "Good Enough" to "Better"

Special PEEK gears (vs. the original PEEK + 316 shaft): a zirconia ceramic shaft combined with high-strength imported PEEK offers clear advantages in mechanical strength, long-term temperature resistance, wear resistance and self-lubrication, making it better suited to long-term, high-load operation with flavors and food additives, with stronger retention of flow accuracy.

At the low flow rate of 0.8 L/min, the MRA — with its superior material system and more stable gear-clearance control — achieves high-precision, highly repeatable metered delivery, meeting the stringent consistency requirements of precision dosing and additive transfer.

Note: The table above compares the characteristics of the two solutions before and after replacement. Flow and accuracy figures are typical/indicative values; actual performance is subject to JONSN's factory test reports and the customer's on-site verification data.

▼ Application Validation: High-Precision Metering Proven Across Scenarios

The MRA series' stable performance in tobacco flavor delivery is built on mature validation across a wide range of low-flow, high-precision applications. Typical applications include:

• Beverage filling: stable low-flow metering of sauces, syrups and flavor liquids;

• Precision dosing: accurate proportional addition at the formulation stage, ensuring batch-to-batch consistency;

• Food additive transfer: friendly to food-grade media, leak-free and easy to clean;

• Low-flow precision metering: repeatable accuracy control at 0.1–2 L/min and across wider flow ranges

▼ Proprietary Core Technology: A Full Alternative to European and American Imports

With its proprietary core fluid transfer technology, JONSN has achieved systematic breakthroughs in material selection, magnetic-drive structure, gear-clearance precision control and localized service for precision gear pumps, and has completed replacement validation against European and American imports in industries including semiconductor process media, coating, liquid cooling, food & beverage, and printing & inkjet.

This 0.8 L/min high-precision tobacco flavor transfer case demonstrates that domestic substitution is not about trading performance for a lower price — it is about better materials, a more reliable structure and service that stays closer to the customer, achieving superiority in both performance and total cost of ownership (TCO). JONSN is becoming a trusted domestic alternative in the field of precision fluid transfer.

From costly reliance on high-priced imports to independent, self-controlled domestic technology, this 0.8 L/min flavor transfer pump is a small but concrete footnote to JONSN's technological self-reliance. With proprietary core technology, we continue to provide customers with fluid transfer solutions that are more stable, more economical and more controllable.
