TRIVAC D 65 BCS 3Ph 200-240/380-400 V 50 Hz / 200-240/400-480 V 60 Hz

TRIVAC D 65 BCS – corrosion-protected version with 65 m³/h

The Leybold TRIVAC D 65 BCS combines the pumping speed of the TRIVAC D 65 B (65 / 78 m³/h at 50 / 60 Hz, ultimate total pressure ≤ 2 × 10⁻³ mbar, DN 40 ISO-KF) with the corrosion-protected equipment of the BCS series. It is intended for pumping corrosive or aggressive media in the chemical industry and semiconductor manufacturing, for research and production, and as a backing pump in pump systems.

Design and function

According to Leybold, the TRIVAC BCS is of corrosion-protected design: yellow metals have been dispensed with; grey cast iron, surface-treated aluminium, steel and stainless steel are used. Added to this are a double shaft seal, a built-in temperature switch for temperature monitoring, the built-in oil pump for continuous operation up to 1000 mbar and the oil-pressure-controlled anti-suckback valve. Together with the chemical oil filter with safety shut-off valve CFS 40-65, the exhaust filter with oil return ARS 40-65, the inert gas system IGS 40-65 and the limit switch system LSS 40-65, the pump forms the TRIVAC SYSTEM. Water vapour tolerance 40 mbar, water vapour capacity 1925 g/h (50 Hz) / 2310 g/h (60 Hz), oil filling 2.0 / 3.3 l, noise level 57 / 59 dB(A) (without / with gas ballast).

PFPE version

The BCS-PFPE variant is prepared for operation with perfluoropolyether LEYBONOL LVO 400 and is supplied without an oil filling. According to Leybold, PFPE is practically inert to chemical and oxidising influences, does not polymerise under high-energy radiation and is thermally highly stable (decomposition only above 290 °C). Leybold recommends always installing a chemical oil filter CF or CFS. Ultimate partial pressure without gas ballast: < 8 × 10⁻⁴ mbar.

Variants of the TRIVAC D 65 BCS

The TRIVAC D 65 BCS is available from Ehrler & Beck in two variants (part numbers 11398, 11399). The rated motor power is 2.2 kW (50 Hz), the weight ranges from 84.5 to 87.9 kg. Voltage, phase and all further data of the individual variants can be found in the variant selection and under Technical data.
