Overview
The Titan VRP-4 is a compact, dual-stage rotary vane vacuum pump engineered for reliable and stable primary vacuum generation in laboratory and light industrial applications. Operating on the principle of positive displacement, it utilizes two counter-rotating vanes within an eccentrically mounted rotor to continuously compress and exhaust gas from the inlet to the outlet. Its dual-stage design achieves ultimate pressures down to approximately 5 × 10⁻³ mbar (typical), making it suitable for applications requiring moderate vacuum levels—including vacuum drying ovens, rotary evaporators, vacuum filtration systems, freeze dryers, and low-pressure distillation setups. Built with precision-machined aluminum alloy housing and hardened steel vanes, the VRP-4 balances mechanical robustness with thermal stability under continuous operation.
Key Features
- Dual-stage configuration for improved ultimate vacuum performance and enhanced pumping efficiency across the 10⁰ to 10⁻³ mbar range
- Oil-lubricated system ensures consistent sealing between vanes and stator, minimizing internal leakage and maximizing volumetric efficiency
- KF16 (ISO-KF 16) quick-release flange enables rapid, leak-tight connection to standard laboratory vacuum lines and accessories
- Integrated oil mist filter and gas ballast valve support operation with condensable vapors and reduce oil contamination risk
- Thermally protected 0.4 kW single-phase induction motor (220 V AC, 50 Hz) delivers stable rotational speed and extended service life
- Compact footprint (320 × 140 × 270 mm) and 19 kg net weight facilitate benchtop integration and equipment mobility
- Oil sight glass and drain plug allow for routine maintenance monitoring and simplified oil replacement per manufacturer-recommended intervals
Sample Compatibility & Compliance
The VRP-4 is compatible with non-corrosive, non-explosive, and non-particulate-laden gases commonly encountered in general-purpose vacuum processes. It is not intended for use with aggressive solvents (e.g., acetone, chlorinated hydrocarbons), reactive gases (e.g., Cl₂, NH₃), or high-humidity vapor streams without auxiliary trapping. As a CE-marked device compliant with IEC 61000-6-3 (EMC) and IEC 60335-1 (safety), it meets essential requirements for electrical equipment used in laboratory environments. While not certified to ISO 22867 or ISO 8573 for compressed air purity, its oil-sealed architecture adheres to widely accepted engineering practices for Class II vacuum pumps per ISO 21360-1 definitions.
Software & Data Management
The VRP-4 operates as a standalone mechanical vacuum source and does not incorporate embedded digital controls, IoT connectivity, or proprietary software. All operational parameters—including inlet pressure, oil temperature, and runtime—are monitored manually via analog gauges or external vacuum measurement instrumentation (e.g., Pirani or capacitance manometers). For laboratories operating under GLP or GMP frameworks, users may integrate the pump into validated vacuum systems using third-party data loggers compliant with FDA 21 CFR Part 11 requirements—provided audit trails, user access control, and electronic signature functionality are implemented at the system level.
Applications
- Rotary evaporation of organic solvents under reduced pressure
- Vacuum-assisted drying of heat-sensitive samples in ovens and desiccators
- Supporting vacuum filtration of aqueous and mild organic suspensions
- Providing rough vacuum for diffusion pump backing or cryopump regeneration cycles
- Enabling controlled atmosphere processing in small-scale glovebox antechambers
- Facilitating degassing of resins, adhesives, and casting compounds prior to curing
FAQ
What is the recommended vacuum oil type for the VRP-4?
Titan specifies ISO VG 68 mineral-based vacuum pump oil (e.g., Shell Vacuol U, Atlas Copco Roto 68) for optimal viscosity index, oxidation resistance, and vapor pressure characteristics.
Can the VRP-4 be operated continuously?
Yes—when installed in a well-ventilated area with ambient temperature ≤35 °C and oil level maintained within the sight glass limits, the pump supports uninterrupted duty cycles up to 8 hours per day.
Is KF16 interchangeable with other flange standards?
KF16 conforms to ISO 2861 and is mechanically compatible with NW16 and DN16 fittings; however, gasket dimensions and clamp torque specifications must align with ISO-KF dimensional tolerances.
Does the VRP-4 include an automatic shut-off feature?
No—the pump lacks integrated thermal overload cutoff or vacuum-sensing auto-stop logic; external control relays or programmable logic controllers (PLCs) must be deployed for safety-critical interlocks.
How often should the vacuum oil be changed?
Under normal laboratory use (≤4 hrs/day), oil replacement is recommended every 500 operating hours or semiannually—whichever occurs first—to preserve pumping speed and ultimate vacuum integrity.
