Overview
The Kashiyama MU180X and MU180XN are high-capacity, oil-free dry scroll vacuum pumps engineered for continuous, contamination-sensitive laboratory and pilot-scale industrial applications. Based on Kashiyama’s proprietary dual-stage scroll technology, these pumps operate without hydrocarbon-based lubricants—eliminating vapor backstreaming, reducing maintenance intervals, and ensuring clean vacuum environments essential for analytical instrumentation (e.g., mass spectrometry sample introduction), thin-film deposition, electron microscopy chamber evacuation, and solvent recovery systems. With a rated ultimate pressure of 1.5 Pa and a maximum pumping speed of 3000 L/min at both 50 Hz and 60 Hz operation, the MU180X/MU180XN delivers stable, pulse-free vacuum generation across wide inlet pressure ranges—from atmospheric down to low rough-vacuum conditions. Its robust cast-aluminum housing, precision-machined stainless-steel scrolls, and integrated thermal management system support long-term reliability under demanding duty cycles.
Key Features
- Dry scroll design with fluorinated oil-lubricated bearings only—no process-side oil exposure or condensable vapors introduced into the vacuum line.
- NW160 inlet flange and NW40 exhaust flange conform to ISO-KF standards, enabling direct integration with common vacuum manifolds and foreline traps.
- Integrated nitrogen purge interface (RC 1/4″ coupling) supports inert gas sealing and dilution during corrosive or reactive gas handling (e.g., Cl₂, NH₃, HCl), extending scroll lifetime and preventing internal oxidation.
- Water-cooled stator jacket with regulated flow (2–3 L/min at 0.2–0.5 MPa gauge pressure) maintains scroll temperature within optimal operational range (10–25 °C ambient), minimizing thermal drift and dimensional instability.
- Three-phase induction motor (2.2 kW, 200–220 V, 50/60 Hz) with ±10% voltage tolerance and 4.5 kVA apparent power rating ensures compatibility with standard industrial power infrastructure in North America, EU, and APAC regions.
- Low-vibration, low-noise operation (<68 dB(A) at 1 m) suitable for shared laboratory spaces and vibration-sensitive equipment installations.
Sample Compatibility & Compliance
The MU180X/MU180XN is compatible with non-condensable gases and low-vapor-pressure solvents typical in rotary evaporation, freeze drying, and vacuum filtration workflows. When used with optional nitrogen purge, it accommodates mildly corrosive process gases in compliance with ISO 21809-3 (offshore pipeline coating) and ASTM D257 (electrical insulating materials) vacuum conditioning protocols. The pump meets CE marking requirements per EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. Its oil-free architecture supports GLP-compliant documentation of vacuum integrity in pharmaceutical stability testing (ICH Q1A–Q5E) and eliminates risk of sample cross-contamination required by USP Analytical Instrument Qualification.
Software & Data Management
While the MU180X/MU180XN operates as a standalone analog-controlled pump, its electrical interface supports integration into centralized facility monitoring systems via optional external PLC modules (e.g., Modbus RTU over RS-485). Real-time status signals—including motor current draw (2.0–13.0 A), cooling water flow confirmation, and nitrogen purge pressure verification—can be logged for preventive maintenance scheduling and audit-ready traceability. All operational parameters adhere to FDA 21 CFR Part 11 principles when paired with validated SCADA platforms, supporting electronic record retention for GMP-regulated laboratories.
Applications
- Rough vacuum generation for electron microscopes (SEM/TEM) and surface analysis tools (XPS, AES).
- Forepump for turbomolecular and diffusion vacuum systems in UHV research setups.
- Vacuum distillation and solvent removal in synthetic chemistry labs.
- Chamber evacuation for physical vapor deposition (PVD), sputtering, and plasma etching.
- Process vacuum in lyophilization and vacuum ovens where hydrocarbon-free environments are mandatory.
- Environmental simulation chambers requiring repeatable, low-maintenance vacuum cycling.
FAQ
What distinguishes the MU180X from the MU180XN model?
The MU180XN includes an integrated nitrogen purge regulator and calibrated flow control for consistent inert gas delivery; the MU180X requires external regulation.
Is this pump suitable for pumping solvent vapors?
It is rated for low-saturation-pressure solvents (e.g., hexane, toluene, ethyl acetate) but not high-vapor-pressure or highly condensable media (e.g., water, methanol, DMF) without cold trap protection.
Does the pump require periodic oil changes?
No—only the sealed bearing compartment contains fluorinated oil (0.1 L), which is factory-filled for life under normal operating conditions.
Can it be mounted vertically?
Mounting must follow Kashiyama’s specified orientation: horizontal installation only, with inlet flange facing upward to prevent condensate accumulation in scroll chambers.
What safety certifications does it hold?
CE-marked per EN 60204-1 (safety of machinery – electrical equipment) and RoHS 2011/65/EU compliant; no UL listing is provided by default but can be arranged under special order.
