Overview
The Sanotac SP1020k is a precision-engineered PEEK high-pressure constant flow pump designed for demanding laboratory and pilot-scale applications requiring stable, pulse-minimized fluid delivery under elevated pressure conditions. Built upon positive displacement plunger technology with cam-driven actuation and electronic pulse suppression, the SP1020k delivers highly reproducible volumetric or gravimetric flow control across a wide operational envelope—up to 20 MPa (2900 psi) and 100 mL/min. Its all-PEEK wetted path ensures exceptional chemical resistance to aggressive solvents, acids, bases, and supercritical fluids, making it suitable for integration into HPLC/UHPLC systems, catalytic reaction setups, microreactor platforms, SFC instrumentation, and continuous-flow synthesis modules. Unlike traditional peristaltic or diaphragm pumps, the SP1020k employs a dual-plunger architecture with real-time pressure feedback and adaptive cam-profile compensation to minimize flow pulsation (<1.5% RSD), enabling precise stoichiometric reagent addition and consistent residence time control in kinetic studies.
Key Features
- Integrated pressure and flow sensing—no external transducers required; full digital calibration and parameter tuning via front-panel interface or remote command
- Low-pulsation fluid delivery achieved through synchronized cam motion profiling and active electronic flow stabilization
- Dual-unit flow mode: selectable volumetric (mL/min) or mass-based (g/min) output, compatible with balance-coupled closed-loop control systems
- Configurable pressure protection: programmable upper and lower pressure thresholds with automatic shutdown and alarm logging
- Real-time graphical display of dynamic pressure and flow curves on built-in LCD screen; data exportable to Excel-compatible .xlsx files
- Multi-protocol industrial connectivity: native support for Modbus RTU/TCP, Profibus DP, and Profinet—enabling seamless integration into SCADA, DCS, PLC, and LabVIEW environments
- Scalable control architecture: supports 1:N master-slave configurations (up to 32 units), ideal for multi-solvent gradient systems or parallel reactor arrays
- Auto-calibration function with user-defined correction factors stored in non-volatile memory for long-term accuracy retention
- Integrated plunger rod cleaning cycle to mitigate particle accumulation and extend seal life in abrasive or particulate-laden media
Sample Compatibility & Compliance
The SP1020k’s PEEK fluidic path demonstrates broad compatibility with organic solvents (e.g., THF, DMF, acetonitrile), aqueous buffers, halogenated compounds, strong acids (e.g., HCl, HNO₃ ≤ 6 M), and bases (e.g., NaOH ≤ 2 M). It is unsuitable for hydrofluoric acid, molten alkali metals, or oxidizing agents above 50% concentration without prior material validation. The pump meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and low-voltage safety (EN 61010-1). When operated with Sanotac’s certified firmware and audit-enabled software, the system supports 21 CFR Part 11-compliant electronic records—including timestamped parameter changes, run logs, and calibration history—with role-based access control and electronic signatures. Full traceability aligns with GLP and GMP documentation standards for pharmaceutical process development and QC laboratories.
Software & Data Management
Sanotac provides the PumpControl Suite—a Windows-based application supporting local configuration, real-time monitoring, and automated script execution. The software enables creation of multi-step flow programs (including ramping, hold, and step-gradient profiles), synchronization with external triggers (TTL, analog input), and scheduled data logging at user-defined intervals (100 ms to 10 s resolution). All operational metadata—including pressure setpoints, actual flow deviation, temperature readings (optional external sensor input), and communication error codes—are timestamped and archived with SHA-256 hash integrity verification. Export formats include CSV, XML, and native .xlsx with embedded charts. Remote access is secured via TLS 1.2 encrypted Ethernet/WLAN connections; firmware updates are digitally signed and validated prior to installation.
Applications
- HPLC and preparative chromatography systems requiring solvent delivery stability at pressures up to 20 MPa
- Catalytic hydrogenation, oxidation, and cross-coupling reactions in fixed-bed or slurry-phase reactors
- Supercritical fluid processing (SFC, scCO₂ extraction) with co-solvent blending capability
- Continuous-flow photochemistry and electrochemical synthesis where precise stoichiometry and residence time control are critical
- Materials science workflows including polymerization initiation, nanoparticle synthesis, and MOF crystallization
- Pharmaceutical API process development under ICH Q5–Q7 guidelines, including DOE-based parameter optimization
- Automated feeding in pilot-scale bioreactors and enzymatic cascade systems with pH- or OD-triggered dosing logic
FAQ
What is the maximum allowable backpressure for continuous operation?
The SP1020k is rated for continuous operation at up to 20 MPa (2900 psi); short-term overpressure tolerance is limited to 22 MPa for ≤30 seconds per event.
Can the pump be used with viscous fluids such as polymer solutions or slurries?
Yes—provided the fluid viscosity remains below 500 mPa·s and suspended solids are <5 µm in diameter; optional ceramic-coated plungers and hardened inlet filters are available for abrasive service.
Is flow calibration traceable to NIST standards?
Calibration certificates are provided upon request, referencing gravimetric measurement against NIST-traceable mass standards (OIML R117 compliant) with uncertainty budgets per ISO/IEC 17025.
Does the pump support fail-safe shutdown during communication loss?
Yes—the device implements watchdog timer supervision; loss of heartbeat signal for >5 s triggers immediate flow stoppage and pressure venting via integrated relief valve.
How is firmware updated, and what safeguards prevent corruption?
Updates are performed via signed binary packages delivered over secure HTTPS; boot-level signature verification and dual-bank flash memory ensure rollback capability in case of interruption.
