Kashiyama SDE1203TX Oil-Free Scroll Vacuum Pump

Overview

The Kashiyama SDE1203TX is a high-capacity, oil-free scroll vacuum pump engineered for continuous-duty laboratory and pilot-scale industrial applications requiring clean, hydrocarbon-free vacuum generation. Based on Kashiyama’s proprietary dual-stage dry scroll technology, the SDE1203TX operates without lubricating oil in the compression chamber—eliminating oil backstreaming, vapor contamination, and maintenance associated with rotary vane or oil-sealed pumps. Its design integrates a scroll pump module (SDE120) with an integrated nitrogen-assisted purge and cooling system (KMB1203), enabling stable operation under demanding conditions—including exposure to mildly corrosive vapors, condensable solvents, and reactive process gases. With a rated pumping speed of 20,000 L/min at both 50 Hz and 60 Hz and an ultimate pressure of ≤0.5 Pa, the SDE1203TX serves as a primary roughing or backing pump for high-vacuum systems (e.g., turbomolecular or cryogenic pumps), vacuum drying ovens, freeze dryers, electron microscopy sample preparation chambers, and semiconductor process tool support.

Key Features

• Dry scroll architecture ensures zero oil carryover—critical for ultra-clean vacuum environments compliant with ISO 8573-1 Class 0 (oil-free air/vacuum) requirements.
• Integrated KMB1203 control module enables automated nitrogen purge sequencing, pressure-regulated cooling water flow monitoring, and real-time thermal management—reducing operator intervention and enhancing process repeatability.
• NW100 inlet flange (ISO-KF standard) and NW40 outlet flange provide standardized, leak-tight vacuum interface compatibility with common laboratory and industrial vacuum lines.
• Robust 3-phase motor drive (200–220 V, 50/60 Hz) with ±10% voltage tolerance and 11.0 kVA apparent power rating ensures stable performance across variable grid conditions typical in research facilities and manufacturing labs.
• Fluorinated oil lubrication confined exclusively to the motor and motion transmission components—fully isolated from the vacuum path—maintains long-term bearing life while preserving vacuum purity.
• Front-panel accessible service points and modular KMB1203 electronics simplify preventive maintenance, calibration verification, and GLP-compliant logbook documentation.

Sample Compatibility & Compliance

The SDE1203TX is suitable for vacuum applications involving non-explosive, non-toxic, and non-polymerizing process gases and vapors. When used with optional nitrogen purge (0.05–0.10 MPa gauge, regulated via external pressure-reducing valve), it accommodates intermittent exposure to moisture, acidic vapors (e.g., HCl, HF traces), and organic solvents—common in chemical synthesis, solvent recovery, and analytical sample preparation workflows. The pump meets JIS B 8341-1:2018 (vacuum pump performance testing) and conforms to IEC 60034-1 (rotating electrical machines) safety standards. Its construction materials—including aluminum alloy housing, stainless steel internal scrolls, and fluoropolymer seals—are selected for corrosion resistance and dimensional stability under thermal cycling. While not intrinsically safe, the unit may be installed in Class 1, Division 2 hazardous locations when integrated into a certified system per NEC Article 500.

Software & Data Management

The SDE1203TX does not include embedded firmware or proprietary software but provides analog and digital I/O interfaces compatible with third-party supervisory control systems. The DB-25PF-N connector delivers status signals (pump running, overtemperature, low coolant flow, nitrogen pressure fault) and accepts remote start/stop commands. The HK4/O-004-M terminal block supports discrete 24 VDC control inputs and relay outputs for integration into PLC-based vacuum control panels. All operational parameters—including inlet pressure (via optional external transducer), cooling water flow rate, and nitrogen supply pressure—can be logged via external DAQ systems aligned with FDA 21 CFR Part 11 requirements when paired with audit-trail-enabled SCADA platforms. Routine calibration checks (e.g., ultimate pressure verification per ISO 21360-1, pumping speed validation per ISO 1606) are supported by Kashiyama’s certified service network and documented in factory-issued test reports.

Applications

• Roughing and backing for high-vacuum systems: Turbomolecular pumps, diffusion pumps, and cryopumps in surface science, thin-film deposition (PVD/CVD), and mass spectrometry laboratories.
• Vacuum drying and lyophilization: Controlled dehydration of pharmaceutical intermediates, biologics, and nanomaterials where residual hydrocarbons would compromise stability or regulatory acceptance.
• Electron microscopy: Sample chamber evacuation for SEM, TEM, and FIB-SEM instruments requiring particle-free vacuum to prevent lens contamination and imaging artifacts.
• Process gas handling: Solvent recovery loops, vacuum distillation, and catalyst activation under inert atmosphere—enabled by nitrogen purge integration and corrosion-resistant wetted materials.
• Research-grade vacuum furnaces: Uniform thermal processing of advanced ceramics, battery electrode materials, and aerospace alloys under repeatable low-pressure conditions.

FAQ

What vacuum level can the SDE1203TX achieve without nitrogen purge?
The ultimate pressure of ≤0.5 Pa is specified under standard test conditions (clean, dry air, no purge gas). Performance may vary with gas composition, temperature, and upstream conductance.
Is the pump suitable for pumping solvent vapors?
Yes—when operated with continuous nitrogen purge (0.05–0.10 MPa gauge) to prevent condensation and maintain scroll clearance integrity. Condensable loads must remain below saturation limits at operating temperature.
Does the unit require periodic oil changes in the vacuum path?
No—this is an oil-free scroll pump. Fluorinated oil is used only in the motor and gear train; it is physically isolated from the vacuum chamber.
Can the SDE1203TX be integrated into a GMP-compliant manufacturing environment?
Yes—its modular design, traceable factory calibration, and compatibility with electronic audit trails support qualification under EU Annex 11 and USP Analytical Instrument Qualification protocols.
What cooling water specifications must be maintained for continuous operation?
Cooling water must be deionized or softened, with flow rate held between 4–8 L/min and inlet temperature maintained at 10–25 °C. Pressure must be sustained between 0.3–0.5 MPa (gauge) to ensure adequate heat rejection from the scroll stack.
