Overview
The Sanotac EXP0010 Intrinsically Safe & Flameproof Constant Flow Pump is an engineered solution for precise, reliable fluid delivery in hazardous environments where flammable gases or vapors are present—such as chemical synthesis labs, petrochemical pilot plants, pharmaceutical process development suites, and solvent-handling facilities. Designed and certified to the full suite of Chinese national explosion-protection standards (GB3836 series), the EXP0010 integrates dual-piston positive displacement mechanics with intrinsic safety (‘i’) and flameproof enclosure (‘d’) protection layers. Its core operating principle relies on microprocessor-regulated, parallel-driven piston actuation with real-time solvent compressibility compensation and multi-point flow calibration—ensuring traceable accuracy across a wide dynamic range (0.001–9.999 mL/min) under pressures up to 42 MPa. Unlike general-purpose peristaltic or diaphragm pumps, the EXP0010 employs a true constant-flow architecture optimized for chromatographic, reaction quenching, and continuous-flow synthesis applications requiring long-term stability and minimal pulsation.
Key Features
- NEPSI-certified dual protection: Flameproof enclosure (Ex d IIB T4 Gb) and intrinsically safe circuitry (Ex ia IIB T4 Ga), compliant with GB3836.1, GB3836.2, GB3836.4, and GB3836.18.
- Floating piston design reduces mechanical stress on high-pressure seals, extending service life of 316L stainless steel and ceramic sealing components by >300% versus fixed-piston alternatives.
- Low-pressure pulsation (<0.1 MPa) achieved via cam-profile optimization and real-time electronic pulse suppression—critical for UV detection stability and column integrity in HPLC and SFC systems.
- Multi-slope gradient capability: Combines isocratic, linear, and step gradients into customizable profiles—enabling method development for complex separations without hardware modification.
- Open communication protocol (RS232/RS485) supports integration with third-party chromatography data systems (CDS), LIMS, and PLC-based process control networks—fully compatible with FDA 21 CFR Part 11 audit trail requirements when deployed with validated software layers.
- Self-luminous 256×64 dot-matrix LCD display ensures readability in low-light or glove-box environments; front-panel programming stores up to 10 user-defined methods with flow rate, gradient slope, and pressure limit parameters.
Sample Compatibility & Compliance
The EXP0010 accommodates a broad spectrum of solvents—including acetonitrile, methanol, THF, dichloromethane, and concentrated acids/bases—thanks to its chemically inert wetted path composed of 316L stainless steel, sapphire check valves, PTFE gaskets, and ceramic plungers. It meets material compatibility requirements defined in ASTM D471 and ISO 15142 for elastomer resistance. All electrical interfaces are rated for Zone 1 (gas) and Zone 21 (dust) hazardous locations per IEC 60079-0 and GB3836. The pump’s certification documentation includes full test reports from the National Supervisory Inspection Center for Explosion-Protected Instruments (NEPSI), supporting GLP/GMP facility audits and regional ATEX/IECEx equivalency assessments upon request.
Software & Data Management
While the EXP0010 operates autonomously via its embedded controller, its open ASCII-based command set enables bidirectional communication with laboratory automation platforms. When integrated into regulated environments, it supports time-stamped event logging (start/stop, pressure fault, flow deviation >±0.5%), parameter change history, and user-access authentication—all exportable in CSV or XML formats. Optional firmware upgrades provide enhanced gradient timing resolution (10 ms) and extended memory for method archiving. No proprietary driver installation is required; standard terminal emulators or Python-based control scripts can initiate run sequences, pause operations, or retrieve real-time status (flow, pressure, temperature if optional sensor added).
Applications
- HPLC and UHPLC mobile phase delivery in explosion-risk laboratories (e.g., solvent recovery labs, battery electrolyte R&D).
- Continuous-flow hydrogenation and photochemical reactors requiring stoichiometric reagent dosing under inert or explosive atmospheres.
- Automated sample introduction for online IC/ICP-MS systems handling volatile organometallics.
- Calibration traceability workflows in metrology labs accredited to ISO/IEC 17025—leveraging its ±0.1% flow accuracy and NIST-traceable calibration certificate option.
- Process analytical technology (PAT) deployments aligned with ICH Q8/Q9 frameworks, where consistent flow delivery directly impacts critical quality attributes (CQAs) of active pharmaceutical ingredients (APIs).
FAQ
Is the EXP0010 suitable for use in Zone 0 hazardous areas?
No. The EXP0010 is certified for Zone 1 (gas) and Zone 21 (dust) per GB3836. It is not rated for continuous exposure to explosive concentrations (Zone 0). For Zone 0 applications, consult Sanotac’s Ex ia-only micro-dosing variants.
Can the pump be calibrated in-house using standard gravimetric procedures?
Yes. The open command protocol supports manual calibration mode, and the dual-piston architecture allows verification against NIST-traceable flow standards per ISO 4064-2. Calibration certificates are available upon request.
Does the EXP0010 support analog 0–10 V or 4–20 mA external control inputs?
Not natively. External analog control requires optional I/O expansion module (EXP-IO-01), sold separately and certified to same GB3836 requirements.
What maintenance intervals are recommended for the 10 mL pump head at 42 MPa continuous operation?
Sanotac recommends seal inspection every 500 hours and full piston assembly servicing every 2,000 hours under nominal load. Extended-life kits (ceramic-coated plungers, reinforced PTFE seals) are available for aggressive solvents.
Is firmware update capability accessible remotely via network connection?
No. Firmware updates require local USB-to-serial connection and signed binary files to maintain integrity compliance—consistent with IEC 62443-3-3 security requirements for industrial control devices.
