Supplier: VACUUBRAND GMBH + CO
Description: Rotary vane pump oil, B
Rotary vane pump oil, B has excellent viscosity characteristics and low vapour pressure. Its exceptional chemical resistance, more stable behaviour when pumping oxidants, acid and alkaline vapours, and the fact that it is better tolerated on contact with skin, sets this oil apart from conventional mineral oils. Even after continuous operation for several weeks and months, the oil ensures the pressure is maintained constantly. Used for priming all RE/RZ series pumps.
