Duo 35 | Description
The Pfeiffer Duo 35 Dual Stage Rotary Vane Vacuum Pump is designed and manufactured to meet the demanding requirements of various industrial and scientific applications requiring low to medium vacuum. This Duo 35 can achieve an Ultimate pressure of 2.25×10-3 Torr, has a 3 phase 265/460 VAC 60Hz motor, pumps up to 21 CFM and runs at a modest 61 Db. This Duo 35 runs on P3 Hydrocarbon oil only, which will need to be bought separately in order to be ready for use out of the box.

Standard Series – Standard pumps with mineral oil filling cover a broad range of uses in practically all fields of vacuum technology.
DUO 1.6, DUO 3, DUO 6, DUO 11, DUO 35, DUO 65, DUO 125, and DUO 255
Magnetically Coupled Series – In contrast to the standard pump, these products have a frictionless magnetic coupling. Oil leakage from a wear-prone conventional shaft seal is ruled out in these models.

Corrosive Version (PFPE) – These corrosive versions of our rotary vane pumps are prepared for operation with Pfeiffer Vacuum perfluoropolyether (PFPE) operating fluids. Due to the inert operating fluid, these pumps can be used in highly corrosive processes. PFPE operating fluids must be ordered separately.
DUO35C and DUO65C
Magnetically Coupled Corrosive Version (PFPE) – These corrosive versions of our rotary vane pumps are prepared for operation with Pfeiffer Vacuum perfluoropolyether (PFPE) operating fluids. Due to the inert operating fluid, these pumps can be used in highly corrosive processes. By using the magnetic coupling, the integral leak rate of these pumps is less than 1 · 10-7 Pa m3/s. This maximizes the operating reliability in corrosive applications. PFPE operating fluids must be ordered separately.

Explosion Protected – Especially for processes that take place in explosive environments or for evacuating explosive gases and vapors. It is certified in accordance with ATEX directive 2014/34/EU and meets the high requirements for explosion protection. The ATEX certification is valid for the interior and exterior of the pump. The pump corresponds to equipment category 3G and temperature class T4. All gases up to explosive group IIC can be pumped.
