Kashiyama NeoDry-36G Oil-Free Diaphragm Vacuum Pump

Overview

The Kashiyama NeoDry-36G is a high-performance, oil-free diaphragm vacuum pump engineered for demanding laboratory and analytical applications where contamination-free operation, long-term reliability, and precise vacuum control are essential. Utilizing a multi-stage elastomeric diaphragm mechanism with precision-machined stainless steel valves and chemically resistant PTFE-coated components, the NeoDry-36G achieves an ultimate vacuum pressure of 0.7 Pa (with gas ballast valve closed) and delivers a maximum pumping speed of 600 L/min at atmospheric inlet pressure. Its dry, oil-free architecture eliminates hydrocarbon backstreaming and condensable vapor contamination—making it ideal for vacuum drying, solvent evaporation, mass spectrometry sample preparation, freeze-drying support, and inert-atmosphere glove box evacuation. Designed and manufactured in Japan by Kashiyama Industrial Co., Ltd., the pump complies with IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) standards, and features an integrated IEC C14 power inlet for universal compatibility across global AC voltage ranges (100–240 V, 50/60 Hz).

Key Features

• Oil-free diaphragm technology ensures zero hydrocarbon emission and eliminates routine oil changes or filter replacements
• Low-noise operation (≤50 dB[A] at 1 m) enabled by vibration-damped mounting, acoustic enclosure design, and balanced motor dynamics
• RS485 serial interface supports Modbus RTU protocol for integration into centralized lab automation systems, enabling remote start/stop, real-time vacuum monitoring, and variable-speed control via external PLC or PC-based SCADA
• Optional gas ballast kit increases water vapor handling capacity by up to 10%, extending operational stability during high-humidity processes such as lyophilization or aqueous solvent removal
• Robust mechanical architecture with stainless steel housing, PTFE-sealed valves, and reinforced diaphragms rated for >20,000 hours MTBF under continuous duty
• NW40 ISO-KF inlet flange standard enables rapid, leak-tight connection to vacuum chambers, cold traps, and analytical instrumentation using industry-standard clamps and seals

Sample Compatibility & Compliance

The NeoDry-36G is compatible with non-corrosive, non-explosive gases and vapors—including water, ethanol, acetone, and ethyl acetate—within its specified vapor load limit of 350 g/h. It is not intended for use with halogenated solvents, strong oxidizers (e.g., NO₂, Cl₂), or acidic gases (e.g., HCl, HF) without prior consultation and optional material upgrades. The pump meets CE marking requirements per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). Its construction and documentation support GLP-compliant environments: full traceability of serial-numbered components, factory calibration certificates (vacuum performance verified per ISO 21360-1), and optional audit-ready electronic log files generated via RS485 data logging.

Software & Data Management

While the NeoDry-36G operates autonomously without proprietary software, its RS485 interface allows seamless integration with third-party laboratory information management systems (LIMS) or building management platforms. Users may configure custom data acquisition intervals (1–60 s), set programmable vacuum setpoints with hysteresis control, and trigger digital I/O alarms (e.g., overtemperature, overload, or communication timeout) via Modbus register mapping. All communication adheres to open protocol specifications—no vendor lock-in. For validation-critical workflows, the pump supports time-stamped event logging (start/stop cycles, fault codes, speed commands) compliant with FDA 21 CFR Part 11 when deployed with validated host software and access-controlled user authentication.

Applications

• Vacuum concentration and rotary evaporation of biological samples and pharmaceutical intermediates
• Pre-vacuum conditioning of electron microscopy stubs and TEM grids
• Support vacuum for benchtop X-ray diffractometers (XRD) and thermal gravimetric analyzers (TGA)
• Continuous low-pressure purging in nitrogen-filled glove boxes and inert-atmosphere reactors
• High-throughput sample preparation in QC labs requiring repeatable, contamination-free vacuum profiles
• Integration into automated sample prep workstations where silent, reliable, and programmable vacuum is critical to throughput and reproducibility

FAQ

What is the recommended maintenance schedule for the NeoDry-36G?
Routine inspection every 6 months is advised; diaphragm and valve replacement is typically required after 12,000–15,000 operating hours, depending on vapor load and duty cycle. No lubrication or oil servicing is needed.
Can the NeoDry-36G be used with a cold trap?
Yes—its NW40 inlet port is fully compatible with standard ISO-KF cold traps. When paired with a −50 °C trap, the effective ultimate pressure improves to ≤0.1 Pa for low-vapor-pressure solvents.
Is the RS485 interface galvanically isolated?
Yes—the communication circuit includes opto-isolation and transient voltage suppression, meeting IEC 61000-4-5 surge immunity requirements for industrial lab environments.
Does the pump meet ISO 8573-1 Class 0 air purity requirements?
As a vacuum pump—not a compressed air source—ISO 8573-1 does not apply. However, its oil-free design satisfies ISO 8573-1 Class 0 equivalency for downstream vacuum processes requiring zero hydrocarbon contamination.
What safety certifications does the NeoDry-36G hold?
It carries CE marking, UL recognition (E491705), and conforms to JIS C 61000-6-2/6-3. Full test reports are available upon request for GMP facility qualification.
