ILMVAC WOB-L Dual-Mode Vacuum and Pressure Piston Pump 2534C-02

Overview

The ILMVAC WOB-L Dual-Mode Vacuum and Pressure Piston Pump 2534C-02 is an oil-free, reciprocating piston pump engineered for precise, reliable operation in both vacuum generation and low-pressure positive displacement applications. Based on a robust Wankel-type oscillating piston mechanism—commonly referred to as a “WOB” (Wobble) design—the pump achieves consistent volumetric displacement without lubrication, eliminating risk of oil contamination in sensitive laboratory environments. It operates across a dual-mode pressure range: from atmospheric pressure down to 93 mbar absolute vacuum, and up to +500 kPa (gauge) positive pressure, enabling flexible use in degassing, sample preparation, filtration, controlled atmosphere purging, and small-scale pneumatic actuation. Its compact footprint, low thermal load, and continuous-duty-rated motor support unattended operation in analytical labs, QC facilities, and R&D settings where space, cleanliness, and operational stability are critical.

Key Features

• Oil-free reciprocating piston architecture ensures zero hydrocarbon carryover—essential for GC sample introduction, mass spectrometry interfaces, and solvent-sensitive processes.
• Dual-mode capability: seamlessly switches between vacuum and positive pressure modes via integrated valve configuration—no external manifold or re-plumbing required.
• Integrated analog vacuum/pressure gauge with calibrated scale provides real-time, operator-readable feedback across the full operating range (0–1000 mbar abs / 0–600 kPa).
• Adjustable throttle valve enables fine control over suction rate and backpressure—critical for gentle handling of volatile or foaming samples during rotary evaporation or membrane filtration.
• Low-noise operation (<52 dB(A) at 1 m) and thermally stable motor (93 W, Class F insulation) permit placement inside fume hoods or adjacent to vibration-sensitive instrumentation.
• Modular housing with standardized 7 mm OD exhaust port simplifies connection to common Tygon®, Viton®, or stainless-steel tubing; no proprietary fittings required.
• Service-friendly design: piston seal replacement and valve inspection can be performed with standard hex tools in under 15 minutes—no specialized calibration equipment needed.

Sample Compatibility & Compliance

The 2534C-02 is compatible with non-corrosive, non-condensable gases and vapors at ambient temperatures (5–40 °C). It is not rated for solvent vapors with dew points above 25 °C, halogenated compounds, or acidic gases (e.g., HCl, SO₂) without optional chemical-resistant seals. As a CE-marked device compliant with EN 61000-6-3 (EMC) and EN 61000-6-2 (immunity), it meets essential requirements for electromagnetic compatibility in shared laboratory infrastructure. While not intrinsically safe, its low surface temperature rise (<35 K above ambient) and absence of ignition sources make it suitable for general-purpose lab use per IEC 61010-1. Documentation includes EU Declaration of Conformity and RoHS 2 compliance statement—supporting GLP audit readiness and procurement traceability.

Software & Data Management

The 2534C-02 is a standalone, analog-controlled instrument with no embedded firmware or digital interface. All operational parameters—including vacuum level, pressure setpoint, and runtime—are monitored manually via the front-panel gauge and mechanical throttle. This design prioritizes reliability, eliminates cybersecurity exposure, and avoids software validation burdens under FDA 21 CFR Part 11 or ISO/IEC 17025. For laboratories requiring electronic logging, integration with third-party data acquisition systems (e.g., LabVIEW, Delta Tau PMAC, or Siemens S7 PLCs) is supported via optional 0–10 V analog output modules (sold separately), enabling time-stamped vacuum/pressure trend recording aligned with LIMS workflows.

Applications

• Primary vacuum source for benchtop rotary evaporators (up to 2 L flasks) and cold traps in solvent recovery systems.
• Positive-pressure driver for inert gas blanketing of reaction vessels, glovebox purge cycles, and controlled-atmosphere sample storage.
• Vacuum-assisted filtration in HPLC mobile phase degassing, particulate removal from aqueous standards, and microbiological membrane filtration.
• Actuation of low-force pneumatic valves, microfluidic chip priming, and vacuum chucking in metrology fixtures.
• Backup or redundancy pump in multi-stage vacuum systems—particularly where oil-free integrity must be preserved upstream of turbomolecular or diffusion pumps.

FAQ

Is the 2534C-02 suitable for continuous 24/7 operation?
Yes—it is rated for indefinite duty cycle at ambient temperatures ≤35 °C and relative humidity <80% non-condensing, provided adequate ventilation around the motor housing is maintained.
Can this pump handle water vapor or condensable solvents?
It is not recommended for sustained pumping of saturated vapors; condensation inside the cylinder may accelerate seal wear. Use only with dry gas streams or install a chilled trap upstream when processing ethanol, acetone, or IPA vapors.
What maintenance intervals are recommended?
Inspect piston seals and valve plates every 2,000 operating hours; replace seals every 6,000 hours or when vacuum hold-down degrades >15% from initial specification (measured at 23 °C, 50% RH).
Does the pump include mounting hardware or inlet filters?
No—standard configuration ships with bare pump body, analog gauge, throttle valve, and 7 mm exhaust port. Optional accessories include anti-vibration feet, inlet particulate filter (10 µm sintered bronze), and vacuum hose kits with ISO-KF 16 adapters.
Is technical documentation available in English with traceable calibration data?
Yes—each unit ships with bilingual (DE/EN) operating manual, EC Declaration of Conformity, and factory test report listing measured ultimate vacuum, flow rate at 50 mbar, and no-load current draw—all traceable to DAkkS-accredited metrology standards.
