Kashiyama SDE-X Series Oil-Free Vacuum Pump

Overview

The Kashiyama SDE-X Series represents a high-efficiency, oil-free dry scroll vacuum pump platform engineered for continuous-duty laboratory, pilot-scale, and light industrial applications requiring clean, hydrocarbon-free vacuum generation. Utilizing a dual-stage, dynamically balanced scroll mechanism with precision-ground stainless-steel and aluminum alloy components, the SDE-X achieves stable ultimate pressures down to 0.5 Pa without lubricating oil—eliminating risk of process contamination, oil backstreaming, or scheduled oil changes. Its design adheres to fundamental principles of positive displacement compression, where two interleaved spiral scrolls (one fixed, one orbiting) create progressively smaller crescent-shaped chambers that compress gas from inlet to exhaust. This architecture delivers high volumetric efficiency, low vibration, and minimal maintenance over extended service life—particularly under cyclic or variable-load conditions typical in vacuum drying, degassing, mass spectrometry sample preparation, glovebox evacuation, and thin-film deposition support systems.

Key Features

• Energy-optimized motor configuration: Power consumption reduced up to 54% versus legacy Kashiyama scroll models—e.g., SDE90X operates at only 1.3 kW while delivering 1,500 L/min pumping speed.
• Robust thermal management: Integrated air-cooling system with IP54-rated fan and optimized fin geometry ensures stable performance across ambient temperatures from 5 °C to 40 °C.
• Wide voltage compatibility: Supports three-phase AC input across global industrial standards—200–220 V (50/60 Hz) and 380–480 V (50/60 Hz)—enabling seamless integration in North America, Europe, and Asia-Pacific facilities.
• Modular scalability: Six standardized models (SDE90X to SDE30M09X) cover pumping speeds from 1,500 to 45,000 L/min, allowing selection based on chamber volume, outgassing rate, and required base pressure.
• Dry operation compliance: Fully oil-free compression path meets ISO 8573-1 Class 0 (zero oil content) requirements—critical for analytical instrumentation, semiconductor R&D, and pharmaceutical process validation.
• Low noise emission: Acoustic pressure level ≤62 dB(A) at 1 m distance—suitable for shared laboratory environments without dedicated mechanical rooms.

Sample Compatibility & Compliance

The SDE-X series is compatible with non-corrosive, non-condensable gases and low-vapor-pressure solvents (e.g., water, ethanol, acetone) within its specified operating envelope. It is not rated for halogenated compounds, strong oxidizers (e.g., O₃, Cl₂), or highly polymerizing vapors. All units are CE-marked in accordance with the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. While not intrinsically safe, optional ATEX-certified variants (SDE-X-ATEX) are available upon request for Zone 2 hazardous locations. The pump’s dry compression mechanism supports GLP-compliant documentation workflows when paired with external pressure loggers and audit-trail-capable SCADA interfaces.

Software & Data Management

The SDE-X operates as a standalone analog device with no embedded controller or digital interface. However, it integrates seamlessly into facility-wide monitoring systems via standard 4–20 mA analog output (vacuum pressure feedback) and dry-contact status signals (running/fault). For data integrity in regulated environments, users may connect third-party validated controllers (e.g., Eurotherm, Watlow) that comply with FDA 21 CFR Part 11 requirements—including electronic signatures, audit trails, and user-access-level permissions. Pump runtime, fault logs, and thermal sensor readings can be archived in SQL-based LIMS or MES platforms when interfaced through RS-485 Modbus RTU (optional add-on module).

Applications

• High-purity vacuum drying of lyophilized biologics and ceramic precursors
• Evacuation of inert-atmosphere gloveboxes (N₂ or Ar) for battery electrode R&D
• Backing pumps for turbomolecular and cryogenic high-vacuum systems
• Sample degassing prior to SEM/TEM imaging or XRD analysis
• Vacuum-assisted resin transfer molding (VARTM) in composite materials labs
• Continuous vacuum packaging development for food science and pharma stability studies

FAQ

Is the SDE-X series suitable for use with aggressive chemical vapors?
No. The pump is designed for clean, non-corrosive gases and low-boiling organic solvents. Exposure to halogens, strong acids, or monomers may degrade scroll surface coatings and compromise sealing integrity.
Does the pump require periodic maintenance beyond filter replacement?
Yes. While oil-free, the inlet particulate filter must be inspected every 500 operating hours and replaced if loaded; scroll wear inspection is recommended at 10,000-hour intervals per ISO 21809-3 guidelines.
Can the SDE-X operate continuously at ultimate pressure?
Yes—its thermal design permits indefinite operation at ultimate pressure (0.5–1.3 Pa), provided ambient temperature remains ≤40 °C and ventilation meets minimum 0.5 m³/min airflow requirements.
What certifications accompany standard SDE-X shipments?
Each unit ships with CE Declaration of Conformity, RoHS 2011/65/EU compliance statement, and full mechanical safety documentation per EN 60204-1.
Is N₂ purge capability built-in?
No. Nitrogen purging is not integrated but can be implemented externally via a T-fitting at the inlet port using a regulated N₂ supply (<50 sccm flow) to reduce moisture adsorption during idle periods.
