Blackmer’s XL Series sliding vane pumps are constructed of ductile iron which will withstand sudden thermal shock and stress beyond the capabilities of cast iron pumps. All models are fitted with replaceable casing liners and end discs that allow easy rebuilding of the pump without the need to remove the pump from the piping. The XL pump models are available in 1.25-, 1.5-, 2-, 3- and 4-in port sizes with capacities from 5 to 345 gpm (19 to 1,305 lpm). The 1.25- and 1.5-in models have NPT-tapped ports and are capable of running at motor speeds up to 1,750 rpm. The 2-, 3- and 4-in models have flanged ports.
