Overview
The Sanotac SP6015 is a prep-scale high-pressure constant flow pump engineered for precise, stable, and repeatable fluid delivery in demanding continuous-flow and batch process environments. Based on dual parallel plunger architecture with floating plunger design, it operates on positive displacement principles—ensuring volumetric accuracy independent of fluid viscosity, density, or compressibility within its operational envelope. Its 600 mL displacement per stroke enables high-throughput applications such as catalyst dosing in fixed-bed reactors, co-feed control in hydroprocessing units, supercritical CO₂ delivery in extraction systems, and reagent metering in electrochemical flow cells. With a maximum pressure rating of 15 MPa (2175 psi) and flow range from 0.01 to 600.00 mL/min (0.01 mL/min resolution), the SP6015 bridges the performance gap between analytical HPLC pumps and industrial process metering pumps—making it suitable for both laboratory-scale process development and pilot-plant integration.
Key Features
- Dual parallel plunger system with floating plunger compensation—minimizes mechanical hysteresis and ensures long-term volumetric stability across pressure and temperature gradients.
- Multi-point flow calibration routine—performed in-situ via front-panel interface or remote software—enables traceable correction across the full 0.01–600 mL/min range, meeting ISO 5725-2 repeatability requirements.
- Integrated pulse suppression: hardware-level cam-profile compensation combined with real-time electronic flow feedback reduces pressure pulsation to ≤0.2 MPa (peak-to-peak), critical for sensitive downstream detectors or pressure-sensitive reaction zones.
- Column plunger rear-wash function—automated solvent flush behind the seal assembly—reduces abrasive wear on ruby/PTFE seals and extends maintenance intervals by up to 3× under abrasive slurry conditions.
- Weight-based closed-loop control interface—supports direct integration with load-cell-equipped reactors, enabling mass-based feed control compliant with ASTM E2656 for gravimetric flow verification.
- Redundant safety architecture: programmable over-pressure limit, zero-point drift compensation, and thermal shutdown protect both equipment and process integrity.
Sample Compatibility & Compliance
The SP6015 accommodates a broad chemical compatibility spectrum through fluid-contact materials including 316L stainless steel, sapphire (ruby) check valves, PTFE seals, and ceramic plungers—validated for use with organic solvents (e.g., THF, DMF), aqueous acids/bases (pH 1–13), supercritical CO₂, and low-viscosity ionic liquids. It conforms to CE machinery directive 2006/42/EC and EMC directive 2014/30/EU. For regulated environments, firmware supports audit-trail-enabled operation (user login, parameter change logging, method version stamping) aligned with FDA 21 CFR Part 11 data integrity expectations when paired with validated SCADA/DCS host systems. Optional GMP-compliant validation documentation packages (DQ/IQ/OQ) are available upon request.
Software & Data Management
The pump supports native operation via intuitive front-panel controls or full remote supervision using Sanotac’s PumpLink™ PC software (Windows/Linux). Key capabilities include: real-time plotting of flow vs. pressure curves with configurable sampling intervals (100 ms–5 s); time-stamped CSV export of all operational parameters (flow, pressure, temperature, status flags); user-defined method libraries with password-protected access levels; and gradient programming with up to 99-step linear/ramp/hold profiles. Analog input (0–10 V / 4–20 mA) allows external process variable synchronization—for example, linking flow rate to reactor temperature or pH feedback. All firmware updates are digitally signed and delivered via secure HTTPS channel.
Applications
- Preparative liquid chromatography (prep-LC) and simulated moving bed (SMB) systems requiring high-volume, low-pulsation eluent delivery.
- Catalytic reaction engineering: precise co-feeding of catalyst precursors, hydrogen, or oxidants into continuous stirred-tank reactors (CSTRs) or tubular reactors.
- Supercritical fluid processing: stable CO₂ or ethane delivery for particle formation (RESS, SAS), impregnation, or extraction at pressures up to 15 MPa.
- Electrochemical synthesis: controlled reagent addition in flow electrolyzers to maintain stoichiometric balance and suppress side reactions.
- Advanced materials synthesis: metering of monomer/solvent mixtures in continuous polymerization or MOF crystallization platforms.
- Pharmaceutical process development: GLP-aligned intermediate dosing in kilo-lab scale API synthesis where flow consistency directly impacts yield and impurity profile.
FAQ
What is the minimum programmable flow rate and its corresponding accuracy?
The SP6015 achieves 0.01 mL/min resolution with ±0.5% full-scale accuracy, verified per ISO 4064-2 gravimetric calibration methodology.
Can the pump be integrated into an existing PLC-controlled plant automation system?
Yes—it supports Modbus RTU/ASCII over RS485, Profibus DP, and Profinet natively, with preconfigured function blocks for Siemens S7, Rockwell Logix, and Schneider EcoStruxure platforms.
Is remote firmware update supported over Ethernet?
Yes—secure OTA updates are enabled via TLS 1.2-encrypted HTTP(S) connection with SHA-256 signature verification.
How often does the plunger seal require replacement under typical organic solvent service?
With rear-wash enabled and operating below 12 MPa, mean time between maintenance (MTBM) exceeds 6,000 hours based on accelerated life testing per ASTM D4170.
Does the pump meet explosion-proof requirements for Zone 1 hazardous areas?
The base unit is non-certified for hazardous locations; however, ATEX/IECEx-certified enclosures and intrinsically safe signal interfaces are available as factory-installed options (model suffix “-EX”).
