Sanotac S-1040 Stainless Steel High-Pressure Metering Pump

Overview

The Sanotac S-1040 is a precision-engineered, electrically driven high-pressure metering pump designed for continuous, accurate, and pulse-minimized fluid delivery in demanding laboratory and pilot-scale process environments. Operating on positive displacement principle with a reciprocating sapphire-plunger mechanism, it delivers stable volumetric flow across its full range (0–100 mL/min) at pressures up to 40 MPa—enabling reliable operation in supercritical fluid applications, catalytic reaction systems, microreactor feed control, and high-backpressure chromatographic workflows. Its robust 316L stainless steel fluid path—complemented by sapphire check valves and PTFE/keramic sealing elements—ensures chemical compatibility with aggressive solvents, acids, bases, and supercritical CO₂, while maintaining long-term dimensional stability under sustained high-pressure loading.

Key Features

• Precision Flow Control: Multi-point flow calibration across the entire operating range ensures ±0.5% flow accuracy and ≤0.1% repeatability—validated per ISO 5167 and ASTM D3923 practices for metering device certification.
• Low-Pressure Pulsation Architecture: Integrated cam-profile compensation and real-time electronic pulsation suppression reduce pressure ripple to ≤0.1 MPa, minimizing vibration-induced column damage in HPLC/UHPLC and ensuring stable residence time in continuous-flow reactors.
• Active Compression Compensation: Dynamically adjusts plunger stroke timing and dwell to counteract fluid compressibility effects at elevated pressures—critical for accurate delivery of low-compressibility solvents (e.g., water, methanol) above 20 MPa.
• Extended Service Life Design: Post-stroke plunger cleaning cycle flushes residual media from seal interfaces, reducing abrasive wear on sapphire/PTFE seals and extending mean time between maintenance (MTBM) to >6,000 operational hours under typical lab conditions.
• Industrial-Grade Connectivity: Standard USB and RS232 interfaces support direct PC integration; optional RS485/422 enables daisy-chained multi-pump synchronization. Native Modbus RTU/ASCII protocol compliance facilitates seamless integration into PLC-controlled reactor skids and SCADA-based process monitoring systems.
• Configurable Operational Modes: Supports constant, linear ramp, and multi-step gradient flow profiles—programmable via front-panel interface or remote software—with real-time graphical display of flow vs. pressure transients and runtime progress tracking.

Sample Compatibility & Compliance

The S-1040 accommodates a broad spectrum of process fluids—including aqueous buffers, organic solvents (THF, DMF, acetonitrile), corrosive reagents (HCl, HNO₃ ≤30%), supercritical CO₂, and viscous polymer solutions (up to 500 mPa·s at 25°C). All wetted components comply with USP Class VI biocompatibility standards and meet FDA 21 CFR Part 11 requirements when used with audit-trail-enabled software configurations. The pump’s mechanical design adheres to CE Machinery Directive 2006/42/EC and conforms to IEC 61000-6-2/6-4 electromagnetic compatibility standards. For GMP/GLP-regulated environments, optional firmware supports electronic signature, user-level access control, and tamper-evident method logging.

Software & Data Management

Optional Sanotac FlowControl™ software provides comprehensive instrument management: real-time plotting of flow rate and system pressure curves; export of timestamped data in CSV and XLSX formats with embedded metadata (operator ID, method name, calibration date); and secure storage of up to 100 programmable flow methods with version history. Calibration routines allow user-defined gravimetric or volumetric verification against NIST-traceable standards, with automatic coefficient recalculation and certificate generation. Remote operation mode supports Ethernet (Modbus TCP) and wireless connectivity (via industrial Wi-Fi gateway), enabling centralized supervision across distributed lab networks—fully compatible with LabVantage, DeltaV, and Siemens Desigo CCMS platforms.

Applications

• Catalytic evaluation reactors requiring precise co-feed of liquid catalysts and substrates under 30–40 MPa H₂ or syngas pressure
• Supercritical fluid processing (SFE, SFC, particle formation) where density-dependent solvent power demands sub-0.5% flow fidelity
• Microfluidic synthesis platforms integrating with pressure-resistant glass or SiC microreactors (ID ≤500 µm)
• Preparative and analytical liquid chromatography systems operating above 1,000 bar backpressure
• Electrochemical flow cells requiring stoichiometric reagent dosing with <1% CV inter-run variability
• Continuous hydrothermal synthesis setups with in-line pH and conductivity feedback loops

FAQ

What is the maximum allowable viscosity for stable operation at 40 MPa?
The S-1040 maintains rated accuracy up to 500 mPa·s at 25°C; for viscosities >200 mPa·s, pre-heating the fluid path to ≥40°C is recommended to mitigate shear-thinning effects and ensure plunger lubricity.

Can the pump be operated in closed-loop pressure control mode?
Yes—when paired with an external pressure transducer and Sanotac FlowControl™ v3.2+, the pump supports PID-based pressure-regulated flow modulation using analog 0–5 V or 4–20 mA feedback signals.

Is third-party calibration documentation available?
Factory calibration certificates traceable to NIM (China National Institute of Metrology) are provided; UKAS-accredited calibration services are available upon request with lead time of 10 business days.

Does the pump meet explosion-proof requirements for hazardous area installation?
The base model is rated IP54; ATEX/IECEx-certified variants (II 2G Ex db IIB T4 Gb) are available as custom builds—contact engineering support for zone-specific configuration.

How frequently should the sapphire plunger and check valves be inspected?
Under continuous operation at ≥30 MPa, visual inspection and leak testing are recommended every 500 hours; replacement intervals average 3,000–4,500 hours depending on fluid abrasivity and particulate content.
