Kashiyama SDL12E50-901 Integrated Screw-Type Vacuum Pump System

Overview

The Kashiyama SDL12E50-901 is an integrated high-vacuum pumping system engineered for demanding laboratory and pilot-scale industrial applications requiring clean, oil-free vacuum generation with stable base pressure and robust throughput capability. This system combines a dry screw vacuum pump (model SD500L) with a mechanical booster pump (KMB1203E-901), enabling efficient evacuation across a broad pressure range—from atmosphere down to ≤0.8 Pa—without reliance on oil-sealed mechanisms. Its design eliminates hydrocarbon backstreaming, making it suitable for ultra-clean environments such as thin-film deposition, vacuum drying of sensitive pharmaceutical intermediates, electron microscopy sample preparation, and analytical instrumentation requiring contamination-free vacuum integrity. The system operates on standard three-phase industrial power (200–220 V, 50/60 Hz) and integrates active cooling via regulated deionized water flow (6–8 L/min at 5–25 °C), ensuring thermal stability during extended duty cycles.

Key Features

• Dual-stage architecture: SD500L dry screw pump (7.5 kW) paired with KMB1203E-901 mechanical booster (3.7 kW) for optimized compression ratio and volumetric efficiency
• Oil-free operation: Eliminates risk of process contamination and reduces maintenance intervals associated with oil changes and filter replacements
• Integrated noise suppression: Dual silencers (SR-48 and SR-49) compliant with ISO 3744 acoustic emission standards for laboratory-friendly ambient noise levels
• Modular control cabinet: Enclosed electrical control unit with PLC-based sequencing, interlock logic, and real-time status monitoring of pump temperatures, coolant flow, and nitrogen purge pressure
• Standardized vacuum interfaces: MF160 inlet flange (ISO-KF compatible) and NW50 exhaust flange (ISO-FM) for seamless integration into existing vacuum manifolds and chamber systems
• Nitrogen purge capability: Configurable inert gas purging (0–50 SLM at 0.1–0.7 MPa) via 3/8″ valved connection to prevent condensable ingress or oxidation during shutdown cycles

Sample Compatibility & Compliance

The SDL12E50-901 is compatible with vacuum chambers, gloveboxes, freeze dryers, and custom-built reaction vessels operating under low-to-medium vacuum conditions. Its oil-free architecture meets stringent requirements for GLP-compliant laboratories conducting residual solvent analysis (per USP ), vacuum-assisted crystallization (per ASTM E2932), and vacuum thermal desorption (per EPA Method TO-17). All electrical components conform to IEC 61000-6-2 (EMC immunity) and IEC 60204-1 (safety of machinery). The system supports audit-ready operational logs when interfaced with validated SCADA platforms compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures.

Software & Data Management

While the base configuration features analog/digital I/O for external supervisory control, optional Ethernet/IP or Modbus TCP interfaces enable integration with LabVantage, DeltaV, or custom LIMS environments. The control cabinet stores timestamped operational data—including pump head temperature, coolant inlet/outlet delta-T, purge gas flow rate, and motor current—for up to 30 days. Data export is supported via USB or RS-485 in CSV format, facilitating traceability per ISO/IEC 17025 clause 7.7 (result reporting) and internal QA documentation protocols.

Applications

• Vacuum distillation and molecular distillation of heat-sensitive organic compounds
• High-throughput lyophilization cycle development with precise vacuum ramping profiles
• Preparation of oxide-free metal surfaces prior to XPS or AES analysis
• Continuous degassing of polymer melts in rheological characterization setups
• Support vacuum for electron beam evaporation systems in nanomaterial synthesis
• Back-up pumping for diffusion pumps or turbomolecular pumps in hybrid vacuum architectures

FAQ

Is the SDL12E50-901 certified for use in Class A cleanrooms?

It is not ISO 14644-1 Class A certified as a standalone unit; however, its oil-free operation and low particle emission profile allow installation in adjacent utility rooms with HEPA-filtered air supply lines routed to the process chamber.
What maintenance intervals are recommended for the SD500L screw rotor assembly?

Under continuous operation at ≤80% load and with proper coolant quality control, Kashiyama recommends inspection every 12,000 operating hours and replacement only upon measured axial play exceeding 0.03 mm per manufacturer’s service manual SM-SD500L Rev. 4.
Can this system be operated without nitrogen purge gas?

Yes—nitrogen purge is optional and primarily used during idle periods to inhibit moisture condensation in the booster stage; omission does not impair primary pumping function but may reduce long-term corrosion resistance in humid environments.
Does the control cabinet support remote diagnostics via Ethernet?

Standard configuration includes isolated digital I/O; Ethernet connectivity requires optional firmware upgrade kit EC-ETH-SDL and configuration via Kashiyama’s proprietary PUMPVIEW software (v3.2+).
Is the cooling water circuit compatible with closed-loop chillers?

Yes—the system accepts recirculated coolant provided chiller output maintains stable temperature (±1 °C) and conductivity remains below 10 µS/cm to prevent electrochemical erosion of stainless steel heat exchangers.
