Utilizing the unique Blackmer® sliding vane design, these Heavy Duty Line positive displacement rotary pumps offer the best combined characteristics of sustained high level performance, energy efficiency, trouble-free operation and low maintenance cost.
The HXL pumps are constructed of ductile iron (ASTM 536) that will withstand sudden thermal shock and stress well beyond the capabilities of cast iron. All models are fitted with replaceable casing, liners and end discs that allow easy rebuilding of the pump, without removing the pump from the piping. Models are available in 6-, 8- and 10-in ANSI flanged port sizes with maximum rated capacities of 755, 1,200 and 2,220 gpm (171, 273, 504 m3/h) respectively. Standard elastomers include FKM O-rings. Optional bolt-on relief valves are designed to protect the pump from excessive pressure are available for all sizes.
