Busch Oils
R-530 oil is equivalent in viscosity to an SAE 30 wt. oil and is recommended for use in most Busch R5 vacuum pumps. R-540 oil is equivalent in viscosity to an SAE 40 wt. oil and is recommended for use in most Busch once-through-sealing vacuum pumps.
Busch R-568 Flushing Oil
Busch R-568 flushing oil is a synthetic fluid formulated to dissolve varnish and soluble sludge from vacuum pumps while they are in operation. It is recommended for use as a flushing agent when changing from a hydrocarbon based oil to a synthetic oil, and in any application which promotes depositions in the pump between oil changes as a cleaning flushing agent.
Busch R-570 and R-580 Pump Oils
Busch R-580 is equal in viscosity to a 15 wt. oil and is recommended for the R50021. Busch R-570 oil is equal in viscosity to a 30 wt. oil and is recommended for all other Busch R5 pumps. Busch R-570 and R 580 are best for operation in low ambient conditions, high temperature applications, for pumps handling high vapor loads, for laboratory applications where acids may be present and applications with halogenating agents.
Busch R-590 Pump Oil
Busch R-590 oil is equal in viscosity to a 30 wt. oil and is recommended as a replacement for standard mineral oils for all pumps running under high ambient temperature conditions. It is also recommended for pumps handling high water vapor loads and for laboratory applications where acids may be present.
