Kashiyama SDL12E50 Oil-Free Dry Scroll Vacuum Pump

Overview

The Kashiyama SDL12E50 is a high-capacity, oil-free dry scroll vacuum pump engineered for continuous, contamination-sensitive laboratory and pilot-scale industrial applications. Utilizing dual-stage, dynamically balanced scroll technology with fluorinated lubricant (1.2 L integrated reservoir), it achieves stable ultimate vacuum levels down to 0.5 Pa without hydrocarbon or silicone vapor backstreaming—critical for analytical instrumentation (e.g., mass spectrometry sample introduction), thin-film deposition systems, and vacuum drying of pharmaceutical intermediates. Its robust cast-iron housing and precision-ground stainless-steel scrolls ensure long-term dimensional stability under thermal cycling, while the integrated nitrogen purge interface (0.1–0.7 MPa, up to 50 SLM) enables inert gas barrier operation during shutdown or process transitions—reducing oxidation risk in reactive material handling. Designed for 24/7 duty cycles in ISO Class 7 cleanrooms or GMP-compliant environments, the SDL12E50 complies with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and meets mechanical safety requirements per ISO 12100.

Key Features

• Oil-free dry scroll architecture eliminates need for oil changes, filtration, or vapor traps—reducing maintenance intervals and operational downtime.
• High pumping speed of 1500 m³/h (25,000 L/min) at inlet, optimized for rapid chamber evacuation in large-volume gloveboxes (≥1.5 m³) and vacuum ovens (up to 200 L capacity).
• Ultimate pressure of ≤0.5 Pa (≤4 × 10⁻³ Torr) verified per ISO 21360-1 using calibrated capacitance manometer traceable to NMIJ (National Metrology Institute of Japan).
• Integrated water-cooling system with flow monitoring: operates within 6–8 L/min at ≥0.2 MPa pressure differential; inlet water temperature range 5–25 °C ensures consistent thermal management across ambient conditions from 15–35 °C.
• Dual-flange configuration: MF160 inlet (ISO-KF compatible) and NW50 outlet facilitate direct integration with standard vacuum piping and foreline trap assemblies.
• Motor rated at 17.7 kVA (3-phase, 200–220 V, 50/60 Hz), delivering high starting torque and low slip under variable load—validated for sustained operation at ≤30 kPa inlet pressure for ≤30 minutes per ISO 21360-2 test protocol.

Sample Compatibility & Compliance

The SDL12E50 is suitable for vacuum processes involving moisture-sensitive, oxygen-reactive, or solvent-laden vapors—including lyophilization of biologics, solvent recovery in extractive purification, and vacuum degassing of polymer precursors. Its fluorinated lubricant formulation (per JIS K 2210) exhibits chemical resistance to common solvents (acetone, ethanol, ethyl acetate) and non-reactivity with NH₃, H₂S, and Cl₂ at partial pressures <100 Pa. The pump conforms to ISO 8573-1:2010 Class 0 for particulate and oil-free air (as applicable to dry pumps), and supports GLP/GMP audit trails when paired with external PLC-controlled vacuum sequencing systems. It is not intended for use with explosive gases, halogenated compounds above 10% vol, or condensable vapors exceeding 10 g/m³ without upstream cold trap integration.

Software & Data Management

While the SDL12E50 operates as a standalone unit with analog status indicators (motor temp, cooling flow, vacuum level via optional analog output), it is fully compatible with third-party SCADA and LabVIEW-based control platforms via 4–20 mA vacuum feedback loop and dry-contact interlock signals (start/stop, overtemp, flow fault). Optional RS-485 Modbus RTU interface enables remote parameter logging—including real-time power draw, cumulative runtime, and nitrogen purge activation timestamps—for 21 CFR Part 11-compliant electronic records when deployed with validated data acquisition software (e.g., NI DIAdem or Siemens Desigo CC).

Applications

• Primary vacuum source for electron microscopy specimen preparation chambers requiring sub-1 Pa base pressure and hydrocarbon-free environment.
• Backing pump for turbomolecular systems in residual gas analyzers (RGAs) used in semiconductor process chamber leak detection.
• Vacuum transfer line for API crystallization reactors where solvent vapor compatibility and absence of oil carryover are mandated by ICH Q5C.
• Continuous-duty vacuum supply in automated freeze-dryer loading/unloading stations compliant with Annex 1 (EU GMP) environmental classification requirements.
• Research-scale physical vapor deposition (PVD) systems where pump-down time <60 s to 10 Pa is required for process repeatability (ASTM F2627-18).

FAQ

What is the recommended cooling water quality specification for continuous operation?
Deionized water with conductivity <5 µS/cm and hardness <1°dH is required; inline 5-µm particulate filtration is mandatory to prevent heat exchanger fouling.
Can the SDL12E50 be operated vertically or tilted?
No—must be installed horizontally on a rigid, vibration-isolated foundation with ≥5 mm clearance around all sides for airflow and service access.
Is nitrogen purge mandatory during shutdown?
Not mandatory, but strongly recommended for processes involving hygroscopic or pyrophoric materials; purge duration should exceed 120 seconds post-shutdown per JIS B 8351-2019 guidelines.
Does the pump meet UL or CE certification for North American or EU installation?
CE marking is affixed per Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU; UL 61010-1 listing is available upon request for specific configurations with certified motor controllers.
What maintenance intervals are specified under typical lab usage (8 hrs/day, 5 days/week)?
Scroll alignment verification and fluorolube top-up every 6,000 operating hours; full scroll inspection and bearing replacement recommended at 12,000 hours—documented in Kashiyama Service Manual Rev. E (2023).
