Sanotac WK0010 High-Pressure Solvent Delivery Pump with Industrial IoT & Wireless Networking Capability

Overview

The Sanotac WK0010 High-Pressure Solvent Delivery Pump is an engineered precision fluid handling system designed for continuous, stable, and programmable delivery of solvents and reagents under elevated pressure conditions—up to 42 MPa (6090 psi). Built upon a dual-piston series architecture with floating piston mechanics, the pump operates on positive displacement principles optimized for low pulsation and high volumetric reproducibility. Its core application domain spans preparative and analytical chromatography systems, microreactor integration, continuous-flow synthesis platforms, and automated process analytical technology (PAT) environments. Unlike conventional constant-flow peristaltic or single-piston pumps, the WK0010 leverages synchronized cam-profile compensation and electronic pulse suppression algorithms to maintain flow stability across variable backpressure scenarios—critical for gradient elution in HPLC, solvent-driven crystallization, or pressurized catalytic reactions. The pump’s mechanical wetted path—comprising 316L stainless steel manifolds, ruby check valves, PTFE seals, and ceramic plungers—ensures chemical compatibility with aggressive organic solvents, aqueous buffers, and mildly corrosive reagents commonly used in pharmaceutical development and fine chemical manufacturing.

Key Features

• Dual-piston serial drive architecture with floating piston design for enhanced mechanical longevity and reduced wear-induced drift
• Real-time pressure and flow rate monitoring with dynamic curve visualization on integrated 256×64 backlit LCD display
• Configurable pressure safety limits—user-definable upper and lower thresholds with automatic shutdown and alarm signaling
• Multi-unit flow calibration support: switch seamlessly between volumetric (mL/min) and gravimetric (g/min) delivery modes
• Column piston back-flush function to prevent salt precipitation and crystalline residue buildup on sealing surfaces and plunger rods
• Comprehensive communication suite: native RS232, RS485, RS422, USB 2.0, 10/100 Mbps Ethernet, and IEEE 802.11 b/g/n WLAN interfaces
• Protocol-native integration: full support for Modbus RTU/TCP, Profibus DP, and Profinet—enabling plug-and-play interoperability with SCADA, DCS, PLC, and LabVIEW-based control architectures
• User-accessible calibration parameter zone for field adjustment of flow response across system-specific load profiles and fluid compressibility conditions

Sample Compatibility & Compliance

The WK0010 accommodates a broad range of liquid-phase chemistries including acetonitrile, methanol, THF, DMF, water-based buffers (pH 2–12), and low-viscosity ionic liquids (<50 cP). Its wetted materials conform to USP Class VI biocompatibility standards for polymer components (PTFE) and meet ASTM F899 specifications for surgical-grade 316L stainless steel. While not certified for intravenous or sterile-fill applications, the pump complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) electromagnetic compatibility requirements. For regulated environments, its audit-trail-capable firmware supports time-stamped event logging—including pressure excursions, flow deviations, and communication handshake records—aligning with GLP documentation practices and serving as foundational infrastructure for future FDA 21 CFR Part 11-compliant validation packages when deployed with validated software layers.

Software & Data Management

The WK0010 does not include proprietary closed-software but exposes all operational parameters via standardized industrial protocols. Engineers may integrate it directly into existing MES or LIMS platforms using Modbus TCP register mapping or Profinet device profiles. Remote diagnostics, firmware updates, and parameter configuration are achievable over secure Ethernet or WLAN using TLS-enabled RESTful endpoints (when paired with Sanotac’s optional gateway module). All real-time pressure and flow traces are timestamped and exportable in CSV format via USB mass storage mode or network file transfer. No local data storage is performed on-device; all logs reside externally—supporting centralized data governance, version-controlled configuration management, and long-term trend analysis per ISO/IEC 17025 Clause 7.7 requirements.

Applications

• HPLC and UHPLC preparative systems requiring sub-0.1% RSD flow stability at pressures up to 42 MPa
• Continuous-flow microreactors for API synthesis, where precise stoichiometric reagent metering impacts selectivity and yield
• In-line PAT workflows integrating with UV-Vis, FTIR, or Raman spectrometers for real-time reaction monitoring
• Automated dissolution testing per USP and , especially for poorly soluble compounds requiring pressurized media delivery
• High-pressure supercritical fluid processing (SFC) auxiliary pumping stages
• Modular lab-scale pilot plants implementing Industry 4.0 principles via OPC UA–enabled edge gateways

FAQ

What is the maximum operating pressure and flow range?
The WK0010 delivers 0.001–9.999 mL/min with a rated maximum pressure of 42 MPa. Flow resolution is 0.001 mL/min, and accuracy is ±0.1% of setpoint under calibrated conditions.
Does the pump support remote firmware updates?
Yes—via Ethernet or WLAN using secure HTTP/TLS when configured with Sanotac’s optional industrial gateway module. Local USB update is also supported.
Can the pump be integrated into a GMP-regulated manufacturing environment?
It provides foundational hardware compliance (EMC, material traceability, deterministic control logic) and supports audit-trail-ready data capture. Full GMP qualification requires site-specific IQ/OQ/PQ execution and integration with validated software layers.
Is there built-in flow calibration capability?
Yes—the user-accessible calibration zone allows multi-point flow correction based on gravimetric or volumetric reference measurements, compensating for fluid compressibility and system backpressure effects.
What maintenance intervals are recommended for the pump head and seals?
Under continuous operation at ≤30 MPa with compatible solvents, the manufacturer recommends inspection every 2000 hours and replacement of ruby check valves and PTFE seals every 4000 hours—or sooner if pressure fluctuation exceeds 0.15 MPa RMS.
