Sanotac S0550/S1040 High-Pressure Micro-Flow Plunger Pump for Water-Jet Guided Laser (WJGL) Systems

Overview

The Sanotac S0550 and S1040 high-pressure micro-flow plunger pumps are engineered specifically for Water-Jet Guided Laser (WJGL) material processing systems. In WJGL technology, a continuous, laminar water jet—typically 20–100 µm in diameter—acts as a light pipe to deliver pulsed or CW laser energy to the workpiece with micron-level precision. This requires a fluid delivery system capable of generating ultra-stable, low-pulsation flow at pressures exceeding 40 MPa (5800 psi), while maintaining sub-0.1% volumetric repeatability across the full operating range. These pumps meet that requirement through a dual-stage cam-driven plunger architecture, integrated electronic pulse suppression, and thermally stable 316L stainless steel fluidic pathways. Designed for integration into OEM laser machining platforms and advanced microfabrication laboratories, they support consistent jet formation critical for kerf-free cutting, high-aspect-ratio drilling, and thermal-sensitive material ablation—including silicon, glass, sapphire, and biomedical polymers.

Key Features

• High-pressure capability: Continuous operation up to 50 MPa (S0550) or 40 MPa (S1040), fully adjustable via digital setpoint control
• Ultra-low pulsation: ≤0.1 MPa pressure ripple achieved via optimized cam profile compensation and real-time electronic flow modulation
• Exceptional metrological performance: ±0.5% full-scale flow accuracy and ≤0.1% RSD repeatability over 0.01–100 mL/min range
• Chemically inert wetted path: 316L stainless steel housing, sapphire check valves, PTFE seals, and ceramic plungers ensure compatibility with ultrapure water, DI water, and low-conductivity aqueous solutions
• Multi-mode operational control: Supports pressure-triggered start/stop, programmable timed dispensing, and ramped flow profiles (constant, linear, gradient)
• Industrial-grade connectivity: Standard USB, RS232, and RS485 interfaces with Modbus RTU protocol; Profinet and CANopen available as factory-configured options
• SCADA/DCS/PLC integration ready: Analog input (0–10 V / 4–20 mA) for remote flow setpoint modulation; discrete I/O for run/stop and fault signaling

Sample Compatibility & Compliance

These pumps are validated for use with deionized water (resistivity ≥18.2 MΩ·cm), nanopure water, and low-viscosity aqueous coolants commonly employed in WJGL beam delivery systems. All wetted materials comply with USP Class VI and ISO 10993-5 biocompatibility standards. The pump architecture conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) for industrial environments. Firmware supports audit-trail-enabled operation per FDA 21 CFR Part 11 requirements when used with compliant host software—enabling electronic signatures, user access levels, and immutable method/data logging for GLP/GMP-aligned labs.

Software & Data Management

The included PC-based control software provides real-time visualization of flow rate vs. pressure curves, program execution progress bars, and synchronized timestamped data logging. All acquired parameters—including instantaneous flow, system pressure, motor current, and temperature—are recorded at configurable intervals (10 ms–10 s) and exportable in CSV or Excel-compatible formats. Users may save and recall multiple flow programs with independent ramp rates, dwell times, and pressure thresholds. On-device calibration functions allow single-point or multi-point volumetric verification using gravimetric or timed-volume methods; calibration coefficients are stored in non-volatile memory with factory reset capability. Remote firmware updates and parameter backup/restore are supported via USB or serial interface.

Applications

• Water-jet guided laser micromachining of semiconductor wafers, MEMS devices, and optical components
• Low-heat-input drilling of brittle materials (e.g., fused silica, BK7, LiNbO₃) without chipping or cracking
• High-precision stent cutting and catheter patterning in medical device manufacturing
• Research-scale laser-assisted additive manufacturing where jet-guided beam delivery enables localized energy deposition
• Integration into automated microfluidic test benches requiring precise high-pressure liquid actuation
• Calibration reference sources for high-pressure flow metrology laboratories (traceable to NIST or national metrology institutes)

FAQ

What is the maximum allowable particulate concentration in the feed water?
Feed liquid must be filtered to ≤0.22 µm absolute rating; suspended solids >0.1 µm risk abrasion of sapphire valves and ceramic plungers.
Can the pump operate continuously at 40 MPa for extended periods?
Yes—rated for continuous duty at full pressure and flow, provided ambient temperature remains between 15–35°C and cooling airflow is unobstructed.
Is flow calibration traceable to international standards?
Yes; on-site gravimetric calibration using certified mass standards (e.g., ASTM E542, ISO 4064-2) is supported, and calibration reports include uncertainty budgets per ISO/IEC 17025 guidelines.
Does the pump support fail-safe shutdown during overpressure events?
Yes—hardware-integrated pressure transducer triggers immediate motor stop and valve isolation within <50 ms upon exceeding user-defined threshold; manual reset required before restart.
Are spare parts and service documentation available globally?
All consumables (seals, plungers, check valves) and service manuals are stocked in EU and US distribution centers; technical support includes remote diagnostics and firmware patch deployment.
