1.4 Lubricants
The same oil can be used for the pump and the gear.
The rotary piston pumps should be run with oil N 62. N
62 is a vacuum pump oil that meets many requirements:
• Low vapour pressure, even at high temperatures.
• Flat viscosity curve.
• Minimum water content and absorption.
• Good lubricating properties.
• Resistant to ageing under mechanical strain.
The use of other special-grade lubricants for specific
applications is possible. Please consult us in such cases.
