Oils for rotary vane pumps have to meet high requirements, especially in circumstances of continuous operation:
low vapor pressure even at high temperatures
excellent lubricating properties
low oil backflow
excellent resistance to aging
resistant to break-down
Rotary-Vane Pump Oil B has excellent viscosity characteristics. Its good chemical resistance, low vapor pressure as well as its better stability when pumping oxidants such as acid and alkaline vapors, makes it superior compared to standard mineral oils. This oil is used for the first filling of RE / RZ / RC series pumps.
Many pumped substances can cause deterioration of common pump oil, leading to mechanical problems. Special oils should be used as a prevention. Special oils may maintain lubricating properties but provide only limited protection against corrosion. The start of the pumps at low temperatures can be impeded.
Vapor pressure at operating temperature of pump: <1 x 10-3 mbar
Viscosity at 40°C: 94mm2/sec
Density at 20°C: 0.87g/cm3
