Overview
The Sanotac KAP6010 is a high-precision dual-piston metering pump engineered for continuous, stable, and traceable fluid delivery under elevated pressure conditions up to 10 MPa. It operates on a parallel dual-piston architecture with floating piston design—enabling true pulse-free flow generation through synchronized displacement and cam-profiled mechanical compensation. Unlike single-piston or peristaltic alternatives, this configuration ensures minimal flow deviation across the full operational range (0.01–600.00 mL/min), making it suitable for demanding applications where volumetric accuracy, long-term stability, and system compatibility are critical. The pump is purpose-built for integration into laboratory-scale reaction systems, catalytic synthesis platforms, supercritical fluid processing units, and continuous-flow chemical manufacturing setups requiring ISO/IEC 17025-aligned fluid control.
Key Features
- Dual-piston parallel drive with real-time cam-curve compensation to suppress pressure pulsation (≤0.2 MPa) and maintain flow continuity
- Multi-point flow calibration capability across the entire range—ensuring ±0.5% flow accuracy and ≤0.1% RSD repeatability
- Integrated pressure protection logic with zero-point drift correction to compensate for ambient thermal and mechanical drift
- Automatic post-stroke plunger cleaning cycle—reducing seal wear and extending service intervals in abrasive or viscous media handling
- Weight-based closed-loop dosing interface—compatible with reactor inlet load cells for gravimetric feed control in exothermic or stoichiometrically sensitive reactions
- Modular communication architecture supporting RS232, USB (standard), and RS485/RS422 (optional) with native support for Modbus RTU/ASCII and Sanotac’s deterministic protocol
Sample Compatibility & Compliance
The KAP6010 accommodates a broad spectrum of process fluids—including organic solvents, aqueous catalyst solutions, supercritical CO₂, polymer melts, and corrosive reagents—via chemically inert wetted path materials: 316L stainless steel housing, ruby check valves, PTFE seals, and ceramic plungers. Its construction complies with CE machinery directive 2006/42/EC and meets IP20 environmental rating for indoor laboratory use. While not intrinsically rated for hazardous area deployment, optional ATEX-compliant variants are available upon request. The pump’s deterministic flow behavior and audit-ready parameter logging align with GLP and GMP documentation requirements; when integrated with validated SCADA or DCS systems, it supports 21 CFR Part 11-compliant electronic records when paired with appropriate software validation packages.
Software & Data Management
The embedded firmware enables real-time visualization of flow rate vs. pressure profiles, progress tracking of multi-step programs, and dynamic unit switching between volumetric (mL/min) and gravimetric (g/min) delivery modes. All operational data—including timestamped flow, pressure, motor current, and alarm status—are logged internally and exportable via USB to CSV or XLSX formats. Method files store gradient profiles (linear, stepwise, or custom-defined), calibration offsets, and safety thresholds—allowing rapid recall and cross-system replication. Remote operation is supported through Sanotac’s optional PC-based control suite, which provides TLS-secured web interface access, role-based user permissions, and automated backup of configuration history for audit trail integrity.
Applications
- Catalytic hydrogenation and oxidation reactors requiring precise co-feed of gaseous and liquid reagents
- Supercritical fluid chromatography (SFC) and extraction systems operating at 10 MPa with CO₂/methanol mobile phases
- Continuous-flow polymerization and nanoparticle synthesis where stoichiometric consistency dictates product morphology
- Foaming extrusion processes demanding stable melt-phase additive injection under backpressure
- Electrochemical energy research—e.g., electrolyte feeding in flow battery test rigs or PEM fuel cell anode/cathode conditioning
- High-pressure hydrothermal synthesis and geochemical simulation reactors with temperature-coupled flow control
FAQ
What is the minimum programmable flow increment?
The KAP6010 offers 0.01 mL/min resolution across its full 0.01–600.00 mL/min range.
Can the pump be integrated into a PLC-controlled process line?
Yes—it supports Modbus RTU over RS485 and digital I/O signals (start/stop, fault reset, run status) for direct DCS/PLC interfacing.
Is the flow accuracy verified per ISO 5725 or ASTM D3120 standards?
Calibration is performed using gravimetric reference methods traceable to NIM (China National Institute of Metrology); formal ISO/ASTM certification requires third-party lab validation per customer specification.
What maintenance intervals are recommended for continuous 24/7 operation?
Plunger seals and check valves should be inspected every 2,000 hours; full preventive maintenance—including cam gear lubrication and encoder alignment—is advised every 6,000 hours.
Does the pump support automatic viscosity compensation?
No—viscosity effects are mitigated mechanically via pressure feedback loop and cam optimization; for highly non-Newtonian fluids, empirical flow correction tables may be loaded via software.
