6:1 & 9:1 Ratios
RAASM 900 series 6:1 and 1200 Series 9:1 Ratio Stainless Steel oil pumps feature a separated air motor and pump design and are ideal for high volume high pressure oil delivery in aggressive environments typical of underground mining and process plant applications. The higher ratios of these pumps make them particularly suited to pumping viscous products longer distances where high pressure drops are experienced.
