ILMVAC WOB-L Dual-Mode Vacuum and Pressure Piston Pump 2546C-02

Overview

The ILMVAC WOB-L Dual-Mode Vacuum and Pressure Piston Pump 2546C-02 is an engineered solution for laboratories requiring precise, oil-free control over both vacuum and positive pressure environments within a single compact unit. Based on the WOB-L (Wobble-Lever) piston principle, this pump employs a non-contact, wear-resistant mechanical drive system that eliminates sliding friction—ensuring long-term stability, minimal maintenance, and consistent performance across repeated duty cycles. Unlike conventional rotary vane or scroll pumps, the WOB-L architecture delivers high volumetric efficiency at low to medium vacuum ranges while simultaneously supporting regulated positive pressure up to 1 MPa (10 bar), making it suitable for applications such as controlled gas dosing, vacuum filtration with back-pressure regulation, leak testing under differential pressure, and sample chamber pressurization prior to analytical transfer. Its dry-running operation guarantees zero hydrocarbon contamination—critical for sensitive applications in analytical chemistry, pharmaceutical R&D, and materials science where residual oil vapor could compromise GC-MS baseline integrity or alter surface adsorption behavior.

Key Features

• Oil-free diaphragm-piston hybrid design ensures contaminant-free operation—fully compliant with ISO 8573-1 Class 0 air purity requirements for critical processes.
• Dual-mode functionality: seamlessly switches between vacuum generation (down to 80 mbar absolute) and positive pressure delivery (up to 1 × 10⁶ Pa) without hardware reconfiguration.
• Integrated analog vacuum/pressure gauge and adjustable needle valve enable real-time process monitoring and fine-tuned flow regulation.
• Robust aluminum housing and reinforced elastomeric diaphragms provide mechanical durability and resistance to chemical exposure from common solvents and process gases.
• Low-noise operation (<52 dB(A) at 1 m) and thermally optimized 190 W motor support unattended, continuous-duty use in shared laboratory spaces.
• Compact footprint (254 × 191 × 229 mm) and lightweight construction (6.3 kg) facilitate benchtop integration, mobile cart mounting, or field-deployable setups.

Sample Compatibility & Compliance

The 2546C-02 is compatible with inert and mildly aggressive gases (e.g., N₂, Ar, CO₂, compressed air) and non-condensable vapors typical in solvent evaporation or lyophilization pre-chamber conditioning. It is not rated for corrosive gases (e.g., Cl₂, NH₃, HCl), halogenated solvents, or explosive atmospheres without additional ATEX-certified enclosures. The pump meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. Its oil-free architecture supports GLP-compliant documentation workflows, and its stable pressure/vacuum output enables validation per ASTM D3924 (vacuum testing of packaging) and ISO 20028-2 (performance testing of laboratory vacuum systems).

Software & Data Management

While the 2546C-02 operates as a standalone analog device, its pressure/vacuum output is fully compatible with third-party digital monitoring systems via standard 0–10 V or 4–20 mA signal interfaces (optional adapter kits available). When integrated into automated platforms, the pump supports audit-trail-capable data logging when paired with compliant SCADA or LabVIEW-based controllers. All firmware updates, calibration certificates, and technical documentation are accessible through ILMVAC’s secure customer portal—maintaining traceability aligned with FDA 21 CFR Part 11 requirements for electronic records in regulated environments.

Applications

• Vacuum-assisted filtration and degassing of polymer solutions prior to rheological or viscometric analysis.
• Controlled atmosphere sample handling in gloveboxes and inert-gas purged analytical chambers (e.g., XRD, XPS).
• Calibration of vacuum gauges and transducers across the 100–80 mbar range.
• Positive-pressure actuation of microfluidic devices and pneumatic valves in custom-built lab automation rigs.
• Pre-conditioning of sorption analyzers (e.g., BET instruments) and thermal desorption units requiring stable inlet pressure profiles.
• Small-scale vacuum impregnation of porous ceramics and composite preforms in materials development labs.

FAQ

Is the 2546C-02 suitable for continuous 24/7 operation?
Yes—the motor and diaphragm assembly are thermally rated for indefinite duty cycle under ambient temperatures ≤35 °C and relative humidity ≤80% non-condensing.
Can this pump handle condensable vapors such as water or ethanol?
It is not recommended for sustained exposure to condensables; optional cold trap integration is advised for applications involving significant vapor loads.
What maintenance intervals are specified by ILMVAC?
Diaphragm replacement is recommended every 12,000 operating hours or 36 months—whichever occurs first—under typical laboratory usage conditions.
Does the unit include vacuum/pressure sensor calibration certification?
A factory-issued calibration certificate (traceable to PTB standards) is provided with each unit; optional UKAS-accredited recalibration services are available upon request.
Is the exhaust port configurable for inline filtration or silencing?
Yes—the 7 mm Ex port accepts standard ISO-KF 10 or NPT 1/4″ adapters, enabling direct coupling to activated carbon filters or acoustic dampeners without modification.
