Yes. In hazardous flammable solvent environments (methanol, acetone, toluene), JONSN magnetic gear pumps eliminate mechanical seals and dynamic arcing. When paired with ATEX-certified flameproof electric motors (Ex d IIC T4 Gb) or American-imported air motors (AM330/AM640) with copper static grounding lines, the entire skid is certified for safe operation in ATEX Zone 1 and Zone 2 hazardous areas across chemical precision dosing applications.

JONSN provides diverse motor-drive pairings for global voltages:

· Brushless DC Motors (BLDC): DC 12V / 24V / 48V integrated brushless drives with hall sensors;

· AC Induction Motors: AC 110V / 220V / 380V (50Hz/60Hz) with IEC/NEMA flange standards;

· Precision Servo & Stepper Motors: For ultra-precise micro-dosing and volumetric dispensing;

· Pneumatic Air Motors: American-imported AM330 (330W) and AM640 (640W) intrinsically safe air drives.

JONSN motor drivers support full industrial automation protocols:

· Analog Signals: 0-5V, 0-10V, and 4-20mA speed regulation;

· Digital Pulse: Pulse Width Modulation (PWM) and frequency pulse control;

· Fieldbus & Industrial Ethernet: Modbus-RTU (RS485), CANopen, and optional Profinet gateways, allowing real-time speed, pressure, temperature, and fault diagnostics feedback into central plant PLCs.

Yes. For major overseas EPC projects, large OEM commissioning, or complex multi-pump skids, JONSN deploys senior application engineers to client sites worldwide for mechanical alignment, PLC bus commissioning, and fluid loop startup. Additionally, our Shanghai engineering center provides 24/7 remote video commissioning support and real-time remote diagnostics via secure telemetry.

Operating with magnetic coupling and static seals, JONSN pumps are essentially maintenance-free for 20,000+ hours under clean fluid conditions. Recommended preventative maintenance includes:

· Regular inspection of inlet suction filters (retaining 300-mesh filtration);

· Annual verification of O-ring elasticity;

· Checking internal gear-to-bushing micro-clearance using feeler gauges after 10,000 hours of aggressive chemical service.

Follow JONSN's 3-step rapid troubleshooting protocol:

· Cavitation Noise: Check if inlet pipe diameter is too narrow (<1.5 m/s recommended) or inlet filter is clogged, causing insufficient NPSHa;

· Reduced Flow: Verify if operating viscosity has increased due to lower ambient temperature (derate speed or activate heating jackets), or check motor power supply voltage;

· Magnetic Decoupling: If differential pressure exceeds 50 bar spikes, reset pump speed to zero and restart smoothly to re-engage synchronous magnetic torque lock.

Yes, absolutely. JONSN strictly respects and protects customer intellectual property. We routinely sign bilateral Non-Disclosure Agreements (NDA) governed by international law prior to reviewing proprietary CAD models, chemical fluid formulations, or specialized OEM chassis constraints. All shared drawings and data are stored on encrypted internal servers with restricted role-based access.

Within 24 hours of receiving your parameters, our Shanghai and Ganzhou application engineering teams provide:
