Sanotac SanoISP Series High-Pressure Constant Flow Piston Pump for Microreactor Integration

Overview

The Sanotac SanoISP Series is an engineered high-pressure constant flow piston pump designed explicitly for integration into continuous-flow microreactor systems used in process intensification, pharmaceutical continuous manufacturing, and fine chemical synthesis. Operating on a dual parallel plunger architecture with floating plunger mechanics, the pump delivers precise, pulse-dampened solvent and reagent delivery under sustained pressures up to 20 MPa — a critical requirement for packed-bed, segmented-flow, and monolithic microreactors where backpressure stability directly governs residence time distribution, mixing efficiency, and reaction reproducibility. Unlike conventional peristaltic or diaphragm pumps, the SanoISP employs direct mechanical displacement with real-time volumetric compensation for fluid compressibility — ensuring traceable mass-based or volume-based dosing across wide viscosity ranges (0.3–500 cP) and temperature gradients (−10 °C to 80 °C). Its modular control interface enables deterministic synchronization with reactor temperature zones, in-line IR/UV sensors, and automated quench modules — forming the foundation of a GLP-compliant, audit-ready continuous processing train.

Key Features

• Dual parallel piston drive with active cam-profile pulsation compensation and electronic flow ripple suppression — achieving pressure pulsation ≤ 0.2 MPa and flow RSD ≤ 0.1% over full range
• Configurable flow units: switch seamlessly between mL/min (volumetric) and g/min (mass-based) using user-defined density inputs for stoichiometric feed control
• Integrated pressure safety logic: programmable upper/lower pressure limits with automatic shutdown and event logging compliant with IEC 61508 functional safety principles
• Post-stroke plunger wash function: automated solvent flush cycle prevents crystallization-induced seal degradation — essential for handling salt-containing or low-solubility reagent streams
• Multi-protocol communication stack: native support for RS-232, USB (standard), RS-485/RS-422 (optional), Modbus RTU/ASCII, and Sanotac’s proprietary ASCII command set for SCADA/DCS-level interoperability
• On-device calibration suite: user-accessible flow correction tables with multi-point curve fitting (up to 10 points) for system-specific fluid compressibility and tubing compliance compensation
• Real-time dual-curve visualization: synchronized pressure vs. time and flow vs. time plots displayed locally on 256×64 backlit LCD; exportable to CSV/Excel for trend analysis and 21 CFR Part 11–compliant record retention
• Scalable control topology: supports 1:1 local operation, binary gradient mixing, or centralized 1:32 daisy-chained configuration via industrial serial bus

Sample Compatibility & Compliance

The SanoISP accommodates aggressive chemistries through chemically inert wetted-path materials: 316L stainless steel housings, sapphire check valves, PTFE seals, and ceramic plungers — validated for compatibility with concentrated acids (e.g., HCl, HNO₃), halogenated solvents (CH₂Cl₂, ClCH₂CH₂Cl), supercritical CO₂ co-solvents, and slurries containing <5 µm particulates. All models meet CE electromagnetic compatibility (EMC) Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. Firmware implements configurable audit trails, electronic signatures, and parameter change logs — aligning with FDA 21 CFR Part 11 requirements when deployed with validated SanoFlu Fluid Control Management Software. System-level validation documentation (IQ/OQ templates) and material certificates (EN 10204 3.1) are provided for GMP pharmaceutical applications per ICH Q5D and ASTM E2500-13.

Software & Data Management

The SanoFlu Fluid Control Management System serves as the central orchestration layer for multi-pump microreactor feeding networks. It provides GUI-based method editor for defining time-resolved flow ramps, pressure hold steps, and conditional triggers (e.g., “increase flow if inlet pressure exceeds 18 MPa”). The software ingests real-time telemetry from integrated load cells or gravimetric dispensers to close the feedback loop — enabling dynamic mass-balance-driven feed rate adjustment without manual intervention. All operational data (flow, pressure, temperature, valve states) are timestamped, digitally signed, and archived in encrypted SQLite databases with optional cloud sync. Export modules generate ISO/IEC 17025-compliant calibration reports and raw Excel datasets with embedded metadata (operator ID, method version, instrument serial number) — satisfying analytical data integrity (ALCOA+) principles required by global regulatory agencies.

Applications

• Pharmaceutical continuous API synthesis: precise stoichiometric delivery of organometallic reagents (e.g., n-BuLi, DIBAL-H) into cryogenic microchannels at −40 °C
• Electrochemical flow reactors: stable biphasic electrolyte/solvent delivery under 15 MPa backpressure for CO₂ reduction studies
• Heterogeneous catalysis in wall-coated microtubes: pulse-free flow maintaining laminar Reynolds numbers (Re < 200) for kinetic regime isolation
• Radiolabeling modules (e.g., ¹⁸F-FDG synthesis): closed-system, single-use pump head configurations meeting USP containment requirements
• High-throughput catalyst screening: 12-pump manifold synchronized via Modbus TCP to execute 96-condition DoE matrices with <±0.3% inter-run flow variance

FAQ

What flow accuracy can be expected across the full operating range?
Flow accuracy is ±0.5% of setpoint (0.01–100.00 mL/min) when calibrated with certified reference fluids at 25 °C and 10 MPa backpressure. Accuracy degrades linearly by ≤0.02%/°C outside 20–30 °C ambient range.
Is the pump compatible with corrosive halogenated solvents?
Yes — all wetted components (including sapphire ball valves and PTFE-coated ceramic plungers) are rated for continuous exposure to CHCl₃, CCl₄, and 1,2-dichloroethane per ASTM D543-20.
Can the SanoISP be integrated into a DeltaV DCS environment?
Yes — via optional RS-485 Modbus RTU interface with pre-certified device description (DD) files for native DeltaV Device Configuration Tool (DCT) integration.
Does the system support automated calibration traceability?
Yes — built-in calibration mode stores user-entered gravimetric verification data (time-stamped mass delta, density, temperature) and auto-generates ISO/IEC 17025-aligned calibration certificates.
What maintenance intervals are recommended for continuous 24/7 operation?
Plunger seals require replacement every 3,000 hours at 15 MPa; check valves every 6,000 hours. Sanotac provides predictive maintenance alerts via SanoFlu software based on cumulative pressure cycles and flow deviation trends.
