Kashiyama SD Series Diaphragm Vacuum Pump

Overview

The Kashiyama SD Series represents a family of high-performance, oil-free diaphragm vacuum pumps engineered for demanding laboratory, pilot-scale, and industrial process applications requiring clean, reliable, and chemically inert vacuum generation. Unlike rotary vane or scroll pumps, the SD Series utilizes a robust multi-stage elastomeric diaphragm mechanism driven by precision-machined eccentric shafts and low-vibration motors—eliminating lubricating oil contamination and enabling continuous operation in solvent-rich, corrosive, or particulate-laden environments. Each model is designed around a modular architecture with optimized gas path geometry, thermally stabilized motor housings, and integrated heat management systems—including an advanced heater system that maintains consistent diaphragm temperature during extended duty cycles, thereby enhancing long-term dimensional stability and reducing performance drift under variable ambient conditions. The series achieves ultimate pressures as low as 0.3 Pa (N₂) and delivers pumping speeds ranging from 10,000 L/min (SDX600) up to 100,000 L/min (SDH6000), making it suitable for applications spanning vacuum drying, freeze-drying support, thin-film deposition, vacuum distillation, and high-throughput sample preparation workflows.

Key Features

• Oil-free operation ensures zero hydrocarbon backstreaming—critical for analytical instrumentation integration (e.g., mass spectrometry inlet systems, residual gas analyzers) and GMP-compliant pharmaceutical processing.
• Multi-stage diaphragm design with reinforced EPDM or fluorocarbon (FKM) membranes provides exceptional chemical resistance to acids, bases, and organic solvents per ASTM D1418 and ISO 1629 classifications.
• Integrated thermal regulation system includes both active heating elements and regulated cooling water channels (3.0–4.0 L/min flow rate), maintaining diaphragm operating temperature within ±2°C across ambient ranges of 5–40°C.
• Compact footprint—models such as the SDX600 occupy only 0.20 m²—enabling installation in space-constrained fume hoods, gloveboxes, or mobile lab platforms without compromising structural rigidity or acoustic emission control.
• CE-marked and manufactured under ISO 9001:2015 quality management system; all units undergo factory validation including leak rate testing (<1 × 10⁻⁶ mbar·L/s He), speed curve verification, and pressure stability profiling over 72-hour continuous operation.
• Motor-driven eccentric mechanism features dynamically balanced rotors and maintenance-free sealed bearings rated for ≥20,000 hours MTBF (Mean Time Between Failures) under nominal load conditions.

Sample Compatibility & Compliance

The SD Series is compatible with non-reactive, non-polymerizing vapors and particulates typical of laboratory vacuum processes—including aqueous, alcoholic, chlorinated, and ketonic solvent vapors—provided inlet filtration (e.g., sintered stainless steel or PTFE-coated cyclonic traps) is deployed where condensable loads exceed 10 g/h. It meets EN 61000-6-3 (EMC emissions) and EN 61000-6-2 (immunity) standards, and its electrical safety complies with IEC 61000-3-2 (harmonic current limits). While not intrinsically safe for Zone 1 hazardous areas, optional ATEX-compliant variants (SD-ATEX line) are available upon request. All models support integration into FDA 21 CFR Part 11–compliant environments when paired with validated SCADA interfaces and audit-trail-enabled controllers (e.g., Kashiyama K-Link V3.2 firmware).

Software & Data Management

Standard SD Series pumps operate via front-panel digital interface with real-time display of suction pressure (mbar/PA), motor current (% load), coolant flow status, and thermal sensor readings. Optional KasNET™ Ethernet module enables Modbus TCP and OPC UA communication for centralized monitoring within LabVantage, DeltaV, or Siemens Desigo CCMS platforms. Data logging supports timestamped CSV export of pressure vs. time profiles, motor temperature trends, and alarm history (e.g., overtemperature, low-flow, or overpressure events)—all traceable to GLP/GMP audit requirements. Firmware updates are performed via secure HTTPS-based OTA protocol with SHA-256 signature verification.

Applications

• Vacuum ovens and lyophilizers requiring stable sub-1 Pa base pressure and high volumetric throughput.
• Chemical vapor deposition (CVD) and physical vapor deposition (PVD) pre-pump stages for semiconductor R&D tools.
• Environmental testing chambers simulating high-altitude or vacuum-exposure conditions per MIL-STD-810H Method 500.7.
• Central vacuum systems for multi-station analytical labs—particularly where cross-contamination between GC-MS, SEM, or XRD instruments must be eliminated.
• Pharmaceutical formulation lines performing vacuum granulation or solvent recovery under cGMP Annex 11 controls.

FAQ

What is the recommended inlet filtration for handling solvent vapors?
A coalescing filter rated for ≤0.3 µm particle retention and compatible with your solvent’s chemical profile (e.g., Parker Hannifin PTFE-lined Series 9000) is advised. For high-boiling-point solvents (e.g., DMSO, glycerol), chilled condenser pre-traps are required.
Can the SDH6000 be operated continuously at full speed for 24/7 duty cycles?
Yes—when installed with verified cooling water supply (≥4.0 L/min at ≤25°C inlet temperature) and ambient airflow ≥0.5 m/s, the SDH6000 is rated for indefinite continuous operation per Kashiyama Technical Bulletin TB-SD-2023-04.
Is remote start/stop and pressure setpoint control supported out-of-the-box?
Basic dry-contact I/O (24 VDC) is standard; analog 4–20 mA pressure feedback and programmable setpoint control require the KasNET™ module and K-Link V3.2 firmware upgrade.
Does Kashiyama provide IQ/OQ documentation packages for GxP-regulated installations?
Yes—validated qualification kits include URS templates, FAT/SAT protocols, calibration certificates traceable to NIST, and electronic copies of risk assessments per ISO 14971.
