Overview
The KJ GROUP YTP550-4E16A is a continuously operable, oil-lubricated rotary vane vacuum pump engineered for stable, low-maintenance performance in laboratory and light industrial vacuum applications. Based on the proven Couette-flow principle of rotary vane displacement, it achieves reliable evacuation across medium-vacuum ranges—specifically optimized for base pressures down to 4 × 10⁻¹ Pa. Its robust cast-aluminum housing, precision-ground vanes, and thermally stabilized motor enable uninterrupted 24-hour operation under ambient conditions ranging from −5 °C to +60 °C. The integrated vertical oil mist filter at the exhaust port significantly reduces oil carryover—minimizing both operational oil consumption and atmospheric hydrocarbon emissions—making it suitable for environments where operator safety and cleanroom-adjacent workflows are prioritized.
Key Features
- Continuous-duty rated motor with thermal overload protection and dual-voltage compatibility (208–240 V, 50/60 Hz)
- High-efficiency rotary vane mechanism delivering consistent 240 L/min (7.8 CFM) pumping speed at atmospheric inlet pressure
- Integrated vertical oil mist filter (standard) with replaceable coalescing element—reduces oil vapor discharge by >95% per ISO 8573-1 Class 4 compliance
- KF25 (ISO-KF) vacuum flange interface ensures rapid, leak-tight connection to standard vacuum chambers, gloveboxes, and deposition systems
- 1100 mL oil reservoir with sight gauge and drain valve for simplified maintenance and extended service intervals
- Compact footprint (440 × 160 × 300 mm) and balanced 25 kg mass facilitate benchtop integration or mobile cart mounting
Sample Compatibility & Compliance
The YTP550-4E16A is compatible with non-corrosive, dry, and mildly condensable gas loads typical in materials science labs—including inert-gas purging, vacuum drying ovens, electron microscopy sample preparation, thin-film evaporation, and vacuum desiccation. It is not designed for halogenated solvents, strong acids, or particulate-laden streams without upstream trapping. While not certified to UL/CSA or CE for standalone safety compliance, its electrical design conforms to IEC 61000-6-3 (EMI emission limits) and IEC 61000-6-2 (immunity). When operated within specified ambient and load conditions, it supports GLP-aligned documentation protocols via external data loggers and meets baseline requirements for ISO 27426 (vacuum system performance verification) when paired with calibrated Pirani and cold cathode gauges.
Software & Data Management
This is a standalone analog vacuum pump with no embedded digital controller or communication interface. All operational parameters—including current draw, temperature rise, and runtime—are monitored externally using third-party instrumentation (e.g., clamp-on ammeters, PT100 surface probes, or programmable logic controllers). For audit-ready operation logs, users may integrate the pump into facility SCADA systems via auxiliary dry-contact status outputs (optional relay module available separately). While the device itself does not support FDA 21 CFR Part 11 electronic signatures or audit trails, its mechanical simplicity and deterministic performance make it well-suited for GMP-compliant processes where vacuum stability—not digital traceability—is the primary critical quality attribute.
Applications
- Pre-evacuation and rough pumping for high-vacuum diffusion or turbomolecular pump systems
- Vacuum sintering and heat treatment furnaces requiring stable 10⁻¹ Pa base pressure
- Thin-film coating systems (e.g., thermal evaporation, e-beam deposition) where low oil backstreaming is essential
- Lab-scale freeze dryers and vacuum concentrators handling aqueous or organic solvent vapors
- Materials characterization workflows including XRD sample chamber evacuation and SEM stub mounting
- Quality control testing per ASTM E557 (vacuum integrity verification) and ISO 20022-2 (vacuum-assisted packaging validation)
FAQ
What vacuum level can the YTP550-4E16A achieve without a secondary pump?
It reaches an ultimate pressure of 4 × 10⁻¹ Pa under clean, dry, room-temperature conditions with recommended KF25 sealing and fresh vacuum oil.
Is the pump compatible with aggressive chemical vapors?
No—it is intended only for non-corrosive gases and low-saturation vapors; use with halogenated or acidic compounds requires a chemically resistant foreline trap.
How often should the oil be changed?
Under continuous operation with clean loads, oil replacement is recommended every 500–1000 hours; frequency increases with humidity or condensable vapor exposure.
Can the vertical oil mist filter be retrofitted to older KJ GROUP pumps?
Yes—the KF25-threaded filter assembly is mechanically compatible with all YTP-series models manufactured after 2019.
Does the pump include vibration isolation feet?
Standard units ship with rubber-damped leveling feet; optional active anti-vibration mounts are available upon request for sensitive optical or metrology setups.
