Sanotac SH1020 Hastelloy High-Pressure Constant Flow Pump (100 mL/min, 20 MPa)

Overview

The Sanotac SH1020 is a high-pressure, constant-flow reciprocating pump engineered for precision fluid delivery in demanding chemical process and analytical environments. Utilizing a dual-piston parallel architecture with floating piston design, it delivers stable, pulse-minimized flow across its full operational range—critical for applications requiring strict mass or volumetric dosing control under elevated pressure. Its core function relies on positive displacement mechanics, where synchronized cam-driven pistons displace fluid through chemically inert wetted pathways constructed entirely from Hastelloy C-276, sapphire, PTFE, and ceramic components. This material selection ensures exceptional resistance to corrosion, pitting, and stress cracking in aggressive media—including strong acids (e.g., HCl, H₂SO₄), halogenated solvents, supercritical CO₂, and high-temperature reactive streams—making the SH1020 suitable for long-term operation in catalytic hydrogenation, hydrothermal synthesis, petrochemical evaluation, and radiochemical handling.

Key Features

• Dual-piston parallel configuration with real-time cam-profile compensation and electronic pulse suppression, reducing pressure ripple to ≤ 0.2 MPa at maximum load
• Full-range flow calibration capability with multi-point correction (0.01–100.00 mL/min), achieving ±0.5% absolute accuracy and ≤ 0.1% RSD repeatability
• Hastelloy C-276 fluidic path—including pump head, check valves, and 1/16″ tubing connections—certified for continuous service up to 20 MPa at ambient to 80 °C
• Integrated column cleaning circuit enabling post-stroke flush of piston seals to minimize abrasive wear and extend service intervals
• Configurable pressure protection logic with zero-point offset compensation to eliminate thermal drift effects on pressure transducer readings
• Modular I/O architecture supporting analog (0–5 V, 4–20 mA), digital (TTL/relay), and serial (RS232/485/422, USB) control modes for seamless integration into PLC, DCS, or SCADA platforms

Sample Compatibility & Compliance

The SH1020 is validated for use with corrosive, viscous, and particulate-laden liquids common in process R&D and pilot-scale synthesis. Its wetted materials comply with ASTM B575 Grade C-276 specifications and meet ASME B31.3 process piping requirements for high-integrity fluid systems. The pump supports GLP/GMP-aligned workflows via audit-trail-capable firmware (when paired with optional Sanotac Control Suite v3.2+), logging all parameter changes, calibration events, and runtime diagnostics with timestamped metadata. It is compatible with ISO 9001-certified manufacturing protocols and conforms to electromagnetic compatibility standards EN 61326-1 and safety standard EN 61010-1 for laboratory equipment.

Software & Data Management

Sanotac Control Suite provides native Windows-based operation with support for method-driven flow programming—including constant, linear ramp, multi-step gradient, and user-defined time-segment profiles. Real-time visualization includes synchronized flow rate vs. pressure trend plots, progress bar indicators, and dynamic error flagging (e.g., overpressure, low flow, seal leakage). All operational data—including timestamps, setpoints, actual values, and system status—are logged in CSV and binary formats, exportable for LIMS integration or statistical process analysis. Firmware supports remote firmware updates, password-protected parameter locking, and factory-reset recovery. Optional OPC UA server module enables secure bidirectional communication with enterprise MES systems under IEC 62443-3-3 cybersecurity guidelines.

Applications

• Microreactor and continuous flow chemistry systems requiring precise stoichiometric reagent feeding
• High-pressure catalytic testing rigs (e.g., Fischer–Tropsch, ammonia synthesis, hydrodesulfurization)
• Supercritical fluid chromatography (SFC) and preparative liquid chromatography (prep-LC) mobile phase delivery
• In-line reaction calorimetry and gravimetric feed control loops interfaced with balance feedback
• Petroleum reservoir simulation cores and enhanced oil recovery (EOR) screening experiments
• Radiolabeling synthesis modules in nuclear medicine labs operating under ALARA principles
• Materials synthesis reactors for MOFs, perovskites, and nanomaterials under hydrothermal or solvothermal conditions

FAQ

What is the maximum continuous operating pressure of the SH1020?

The SH1020 is rated for continuous operation up to 20 MPa (2900 psi) at ambient temperature; derating applies above 60 °C per ASME B31.3 Annex D guidelines.
Can the pump be integrated into a PLC-controlled batch reactor system?

Yes—it provides native Modbus RTU/ASCII support over RS485, plus isolated 4–20 mA analog input for flow setpoint modulation and relay outputs for fault signaling.
Is flow calibration traceable to NIST standards?

Calibration procedures follow ISO/IEC 17025-compliant methodology using certified gravimetric standards; certificate of conformance is issued per unit upon request.
Does the pump support gradient elution for preparative chromatography?

Yes—via time-programmed flow profiles with up to 99 segments, each configurable for rate, duration, and ramp slope; compatible with dual-pump solvent blending configurations.
What maintenance intervals are recommended for routine operation?

Piston seal replacement every 6 months under continuous 20 MPa operation; check valve inspection every 3 months; full fluid path cleaning recommended after each corrosive solvent campaign.
