Overview
The Kashiyama SDE20N12TX is a high-capacity, oil-free scroll vacuum pump engineered for continuous, reliable operation in demanding laboratory and pilot-scale industrial vacuum applications. Designed as a dual-stage dry scroll system, it achieves ultimate pressures down to 0.5 Pa without the risk of hydrocarbon contamination—making it ideal for processes requiring ultra-clean vacuum environments, such as thin-film deposition, vacuum drying, electron microscopy sample preparation, and analytical instrumentation interfacing (e.g., mass spectrometry inlets or residual gas analysis chambers). Its robust architecture integrates a primary SDE120TX scroll unit with an integrated MSB2004 booster module, enabling stable high-throughput evacuation across large-volume chambers or low-conductance piping networks. Unlike oil-lubricated rotary vane pumps, the SDE20N12TX eliminates oil backstreaming, vapor carryover, and scheduled oil changes—reducing maintenance overhead and ensuring long-term vacuum integrity under GLP-compliant workflows.
Key Features
- Dry scroll technology with fluorinated oil-lubricated bearings ensures zero hydrocarbon emission and compatibility with oxygen- or solvent-rich atmospheres.
- Rated pumping speed of 30,000 L/min at both 50 Hz and 60 Hz—optimized for rapid chamber evacuation and steady-state process vacuum maintenance.
- NW160 inlet and NW40 outlet flanges conform to ISO-KF standards, supporting standardized vacuum plumbing and easy integration into existing systems.
- Integrated nitrogen purge interface (RC 3/8″ coupling) enables active sealing against corrosive or condensable vapors; purge flow is adjustable from 0 to 60 L/min depending on process requirements.
- Water-cooled design with regulated flow (4–8 L/min) and pressure differential control (min. 0.3 MPa delta P) ensures thermal stability during extended operation at full load.
- Industrial-grade electrical interface: 3-phase, 200–220 V supply with ±10% voltage tolerance and 14.5 kVA demand; includes Tyco HK4/O-004-M connector and DB-25PF-N I/O port for external PLC or SCADA integration.
Sample Compatibility & Compliance
The SDE20N12TX is suitable for non-reactive, mildly corrosive, and condensable gas streams when used with appropriate nitrogen dilution and cooling. It complies with JIS B 8341-1 (vacuum pump performance testing) and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not intrinsically rated for Class I Div 1 hazardous locations, its oil-free operation and sealed motor enclosure (IP54) support use in ISO Class 5–7 cleanrooms and GMP-aligned R&D facilities. For FDA-regulated applications involving vacuum-assisted lyophilization or packaging, the pump’s audit-ready operational logs (via optional software) support 21 CFR Part 11 compliance when paired with validated data acquisition systems.
Software & Data Management
The SDE20N12TX operates as a standalone hardware platform but supports digital monitoring via its DB-25PF-N interface, which provides analog outputs (0–10 V) for vacuum level, coolant flow, and motor temperature, alongside discrete status signals (e.g., “Run”, “Fault”, “Coolant Low”). When integrated with Kashiyama’s optional VAC-Link™ control module or third-party LabVIEW/Python-based DAQ systems, users can log real-time performance metrics—including cumulative runtime, purge gas consumption, and thermal deviation history—for preventive maintenance scheduling and audit documentation. All firmware updates are delivered via secure USB interface and retain full traceability per ISO/IEC 17025 calibration record retention guidelines.
Applications
- High-throughput vacuum ovens and freeze-dryers in pharmaceutical development labs.
- Backing pumps for turbomolecular or cryogenic high-vacuum systems.
- Vacuum degassing of resins, adhesives, and battery electrolytes prior to casting or encapsulation.
- Process vacuum in physical vapor deposition (PVD) and sputtering systems where hydrocarbon-free base pressure is critical.
- Environmental simulation chambers requiring rapid cycling between atmospheric and sub-1 Pa conditions.
- Research-scale vacuum distillation and molecular distillation setups handling thermally sensitive compounds.
FAQ
What is the recommended nitrogen purge pressure for standard operation?
A regulated nitrogen supply at 0.05–0.10 MPa (gauge) is advised for optimal sealing and dilution efficiency during routine operation.
Can this pump handle water vapor or solvent vapors without damage?
Yes—provided nitrogen purge is activated and cooling water flow remains within specification (4–8 L/min); prolonged exposure to saturated condensables without purge may accelerate scroll wear.
Is the motor protected against voltage fluctuations?
The drive electronics tolerate ±10% variation around nominal 200–220 V input; however, sustained operation outside this band requires external voltage stabilization.
Does the pump require periodic oil replacement?
No—scroll elements operate dry; only fluorinated bearing oil (DP: 0.7 L, MB: 0.6 L) requires inspection every 12,000 operating hours per Kashiyama’s maintenance schedule.
What is the minimum allowable cooling water pressure differential?
A minimum pressure drop of 0.3 MPa between inlet and outlet is mandatory to ensure adequate heat transfer and prevent thermal throttling.
