We fully support prototype testing for qualifying OEM integrators. Sample units are manufactured to 100% production-grade standards inside our Ganzhou smart base and bench-tested before dispatch. When an OEM customer transitions the evaluated model into mass production and reaches the agreed annual batch milestone (typically 20+ units), the initial sample cost differential can be credited back into the mass order.

JONSN maintains lean inventory of raw materials (316L, Hastelloy C-276, PEEK blanks) to ensure industry-leading lead times:

· Standard Models: Dispatched in 2–4 weeks (coMPared to 16–24 weeks for legacy European/US brands);

· Custom OEM Models: Sized, 3D modeled, carved via Mazak CNCs, and delivered in 4–6 weeks;

· Replacement Spare Parts: PEEK gears, Zirconia ceramic shafts, and O-ring kits dispatched within 48–72 hours from our Ganzhou warehouse.

Yes. For critical production downtime or urgent EPC commissioning schedules, JONSN activates an Emergency Fast-Track Channel. By prioritizing CNC machining schedules across our Haas and Mazak centers and utilizing dedicated test benches, emergency replacement pump units can be manufactured, bench-qualified, and express-shipped (via DHL/FedEx/Air Freight) within 7–10 working days.

Yes. JONSN has extensive engineering experience replacing legacy imported pumps across semiconductor, chemical, and medical lines. We match or exceed original mounting bracket bolt patterns, port centerline heights, thread standards (NPT/G/VCR), and performance curves. OEM designers can achieve 1:1 drop-in replacement without altering equipment chassis dimensions or piping layouts.

JONSN pumps match or outperform European/American benchmarks. Validated by our 2026 strategic partnership with AMEC (Advanced Micro-Fabrication Equipment Inc.), JONSN pumps demonstrated superior corrosion resistance and volumetric stability, outperforming imported brands. Key metrics include:

· Lifespan: 3x longer than conventional gear pumps (20,000+ hours maintenance-free);

· Flow Attenuation: Strictly 2% after 10,000 continuous hours (industry average: ≤5% per 6 months);

· Repeatability: ±0.2% precision metering for chemical precision dosing applications.

JONSN provides a standard 12-month factory warranty from the date of commissioning (or 18 months from shipment date, whichever occurs first). Extended warranty packages (up to 24–36 months) are available for critical OEM projects. The warranty covers all defects in materials, CNC machining tolerances, dynamic magnetic coupling, and factory assembly, with immediate free repair or unit replacement.

JONSN solves long-term flow decay through four proprietary technological advantages:

1. Modified PEEK Ceramic Bearings: Wear resistance 5x higher than standard industry bushings;

2. Nanostructural Zirconia Shafts: Micro-polished ceramic shafts that resist abrasive wear;

3. High-Coincidence Gear Profiles: Precision-machined on Mazak 5-axis centers to minimize tooth deformation;

4. Dutch Bronkhorst Mass Flow Bench Verification: 100% empirical validation of volumetric stability before shipment.

We support flexible international payment methods based on customer credit rating and order nature:

· Sample Orders / First-Time Buyers: 100% T/T wire transfer before dispatch;

· Standard Batch OEM Orders: 30% T/T deposit with order confirmation, 70% balance T/T before shipment (upon inspection report release);

· Large EPC Projects / High-Volume Accounts: Irrevocable Documentary Letter of Credit at sight (L/C at sight) or open account (OA 30–60 days) via Sinosure credit underwriting.

We accept direct settlement in USD, EUR, GBP, CHF, and CNY (RMB). Our pricing structure features transparent tiered volume discounting: Tier 1 (1–9 units prototype/trial), Tier 2 (10–49 units small batch), Tier 3 (50–199 units annual OEM contract), and Tier 4 (200+ units framework contract with locked annual pricing).

JONSN supports standard Incoterms 2020 terms: FCA (Shanghai), FOB (Shanghai Port), CIF (Destination Port), CFR, CPT, and DDP (Delivered Duty Paid). For customers requiring door-to-door convenience without customs handling, we provide complete DDP air/sea freight services with customs duties and import taxes prepaid.

All JONSN pumps are packaged in heavy-duty export packaging:

· Fluid ports sealed with anti-dust protective caps;

· Pump body vacuum-sealed in anti-static, moisture-proof VCI foil bags with desiccant packs;

· Suspended in high-density custom EPE foam inside custom-reinforced, fumigation-free plywood export crates compliant with ISPM-15 standards, tolerating harsh sea-freight vibration and drops.
