BUSCH VACUUM PUMP OILS
R-500 SERIES DESCRIPTION
Busch R-530 and R-540 Series Pump Oils Busch R-530 and R-540 Series vacuum pump oils are detergent free oils derived from highly refined paraffiniccrudes with excellent lubricating properties. The combination of high viscosity indexes and low pour points ensures ease of handling and flow in all but extreme temperature situations. R-530 oil isequivalent 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 Buschonce-through-sealing vacuum pumps. Busch R-570 and R-580 Pump Oils Busch R-570 and R-580 vacuum pump oils are synthetic compounded polyalphaolefins which offer excellent protection against wear, rust,and corrosion, and have superb low temperature flow characteristics. They are very stable at high temperatures, resisting oil breakdown due to oxidation, which allows a pump to run longer between oilchanges compared to standard mineral oils and semi-synthetic oils. They are also non-foaming and have excellent water resistance, eliminating the harmful formation of emulsions. Busch R-580 is equalin 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 foroperation in low ambient conditions, high temperature applications, for pumps handling high vapor loads, and for laboratory applications. Busch R-590 Pump Oil Busch R-590 vacuum pump oil is asemisynthetic, hydrocracked, dewaxed paraffinic oil which also offers excellent protection against wear, rust, and corrosion. It is stable at high temperatures, resisting oil breakdown due to oxidation,which allows a pump to run longer between oil changes when compared to standard mineral oils. It is non-foaming and has excellent water resistance, eliminating the harmful formation of emulsions. Busch...
