Oil-sealed two-stage rotary vane pump with a nominal pumping speed of 4 L/s at 50 Hz and an ultimate pressure of 4 × 10−2 Pa with the gas ballast closed. DN25KF connections, gas ballast and anti-suckback protection support laboratory and industrial backing service.
Description
KYKY RV4 Rotary Vane Vacuum Pump
The RV4 is a direct-drive, two-stage oil-sealed rotary vane pump for rough-vacuum operation and high-vacuum pump backing. It is suitable for clean, non-reactive gases within the limits of the manufacturer manual.
| Nominal pumping speed | 4 L/s at 50 Hz; 4.8 L/s at 60 Hz |
|---|---|
| Ultimate pressure, gas ballast closed | 4 × 10−2 Pa in the applicable manufacturer manual |
| Ultimate pressure, gas ballast position II | 4 Pa |
| Inlet / exhaust connection | DN25KF |
| Oil charge | Approximately 1.2 L; use manufacturer-approved vacuum oil |
| Motor | 0.55 kW in the manufacturer family catalog; confirm voltage and phase |
| Nominal speed | 1,420 rpm at 50 Hz; 1,710 rpm at 60 Hz |
| Noise with gas ballast closed | Approximately 50 dB(A) under the stated test conditions |
| Approximate weight | 28 kg |
Gas ballast assists with condensable vapor, while an anti-suckback valve reduces oil migration when the pump stops. Common uses include leak detectors, vacuum chambers, analytical instruments, coating systems and turbomolecular pump backing.
The source page listed a different motor power and noise value; this English card follows the KYKY family catalog. Confirm the current pump revision, motor, cable, fittings, oil and exhaust treatment before ordering. Provide safe ventilation and assess all hazardous or reactive process gases separately.
