Titan VWP-5 Circulating Water Vacuum Pump

Overview

The Titan VWP-5 Circulating Water Vacuum Pump is an oil-free, water-sealed vacuum generation system engineered for reliable, low-maintenance operation in academic laboratories, quality control environments, and small-scale industrial R&D settings. It operates on the principle of water ring vacuum generation: rotating impeller motion creates a liquid ring inside the pump chamber, forming sealed cavities that expand to draw in gas and contract to expel it—enabling continuous vacuum production without lubricating oil or hydrocarbon contamination. With an ultimate vacuum capability of 0.098 MPa (equivalent to ~98 kPa absolute pressure or ~20 mbar residual pressure), the VWP-5 supports common vacuum-dependent applications including rotary evaporation, vacuum filtration, vacuum drying, and suction filtration under ambient conditions. Its compact vertical architecture and integrated water reservoir eliminate external cooling lines, reducing setup complexity and footprint while maintaining stable performance across extended duty cycles.

Key Features

• Oil-free design ensures clean vacuum output—critical for solvent-sensitive processes and compliant with ISO 8573-1 Class 0 air purity requirements for non-lubricated systems.
• Integrated 12-L water reservoir with level indicator and overflow protection minimizes manual refilling and prevents dry-run damage.
• Stainless steel inlet/outlet ports and corrosion-resistant PVC housing provide long-term durability against organic solvents and mild acids commonly used in chemistry labs.
• Thermally protected 550 W induction motor delivers consistent torque across variable load conditions, with IP54-rated enclosure for dust and splash resistance.
• Adjustable vacuum regulation via dual-stage vent valve allows fine-tuned control over suction pressure (0.03–0.098 MPa range) without external throttling valves.
• Low-noise operation (<62 dB(A) at 1 m) meets ISO 7779 standards for laboratory acoustic environments, supporting shared workspace usability.

Sample Compatibility & Compliance

The VWP-5 is compatible with standard laboratory glassware interfaces (e.g., 10/15/19/24 standard taper joints) and integrates seamlessly with common vacuum accessories such as Büchner funnels, Hirsch funnels, rotary evaporator condensers, and vacuum desiccators. As a water-ring pump, it tolerates brief exposure to saturated vapors from aqueous or low-boiling organic solvents (e.g., ethanol, acetone, ethyl acetate); however, prolonged use with high-vapor-pressure solvents or aggressive halogenated compounds (e.g., chloroform, DCM) requires optional cold trap integration. The unit complies with GB/T 18039.3–2013 (China’s electromagnetic compatibility standard for laboratory equipment) and conforms to general safety requirements outlined in IEC 61010-1:2010 for electrical equipment used in laboratory environments. While not certified for hazardous area use (ATEX/IECEx), its oil-free construction supports GLP-aligned documentation practices where trace hydrocarbon contamination must be excluded from analytical workflows.

Software & Data Management

The VWP-5 is a standalone analog-operated device with no embedded microcontroller or digital interface. It features mechanical vacuum gauge readout (0–0.1 MPa scale) and manual flow control—designed for simplicity, reliability, and ease of validation in regulated environments. For users requiring audit-ready operational records, the pump may be integrated into broader lab infrastructure via external pressure transducers (e.g., Honeywell ASDX series) connected to SCADA or LIMS platforms. When deployed in FDA-regulated facilities, its fixed-function architecture simplifies 21 CFR Part 11 compliance: no electronic records are generated internally, eliminating requirements for electronic signature controls or audit trail configuration. Routine maintenance logs—including water replacement frequency, motor temperature checks, and seal inspection intervals—can be maintained per ISO/IEC 17025 clause 6.4.10 for equipment verification.

Applications

• Routine vacuum filtration of crystalline precipitates, cell suspensions, or particulate contaminants using sintered glass or membrane filters.
• Rotary evaporation of heat-labile compounds at reduced boiling points, particularly where solvent recovery mandates oil-free vacuum integrity.
• Vacuum-assisted degassing of polymer precursors, resin mixtures, or coating formulations prior to casting or curing.
• Supporting vacuum ovens and desiccators for moisture-sensitive material storage or gravimetric analysis sample conditioning.
• Providing primary vacuum for basic distillation setups, cold traps, or Schlenk line manifolds in synthetic chemistry teaching labs.

FAQ

What is the recommended water replacement interval for continuous operation?
Under continuous 8-hour shifts at ambient temperatures ≤25°C, replace the circulating water every 24 hours; increase frequency to 12-hour intervals if inlet water temperature exceeds 30°C or if solvent vapor loading is significant.
Can the VWP-5 be used with corrosive gases such as HCl or Cl₂?
No—standard configuration is unsuitable for highly corrosive or oxidizing gases. Optional PVDF-lined impeller and EPDM elastomer seals are available upon request for limited HCl vapor service, but full chemical compatibility assessment must precede deployment.
Is the pump suitable for cleanroom environments?
Yes, provided the water reservoir is filled with purified water (≥15 MΩ·cm resistivity) and operated within ISO Class 8 (100,000) or lower cleanliness classifications; no particle shedding or outgassing has been observed during validated testing.
Does Titan provide calibration certificates or metrological traceability?
Factory calibration of the mechanical vacuum gauge is performed per JJG 52–2013 (Chinese national metrology verification regulation); NIST-traceable calibration certificates are available as a value-added service upon order confirmation.
What is the expected service life under typical laboratory usage?
With biannual bearing lubrication (using ISO VG 32 mineral oil) and quarterly impeller clearance checks, mean time between failures exceeds 12,000 operating hours based on field data from 2020–2024 installations across 87 institutions.
