Leybold TRIVAC D 4 T – two-stage rotary vane pump of the TRIVAC T series
The TRIVAC D 4 T reaches a pumping speed of 4.3 m³/h at 50 Hz (nominal pumping speed 5.3 m³/h) and an ultimate total pressure of 5 × 10⁻³ mbar without gas ballast. With gas ballast the ultimate total pressure is 8 × 10⁻³ mbar in position 1 and 2 × 10⁻² mbar in position 2. The water vapour tolerance is 15 mbar, the water vapour capacity 55 g/h. Intake and exhaust side are designed as DN 16 ISO-KF, the oil filling is 0.6 / 0.9 l (min. / max.), the noise level 52 / 54 dB(A) without / with gas ballast. The pump is designed for ambient temperatures of 12 to 45 °C. The data are taken from the Leybold brochure “TRIVAC T Series”.Versions and order numbers
