Spec Sheet 102-001 Section: Effective: Replaces: HXL Series Shock-Resistant, Ductile Iron Pumps Design Features 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-inch ANSI flanged port sizes with maximum rated capacities of 755, 1,228 and 2,220 gpm (171, 279, 504 m3/h) respectively. Standard elastomers include FKM O-rings. Optional bolt-on relief valves designed to protect the pump from excessive pressure are available for all sizes. The HXLJ8 model features jacketed heads for high viscous and high temperature applications. Base-mounted unit assemblies with commercial gear reduction drives are available for all HXL models. Consult factory for details. Benefits Utilizing Blackmer’s unique sliding vane design, these positive displacement rotary pumps offer the best combined characteristics of sustained high level performance, energy efficiency, troublefree operation and low maintenance cost. Applications Blackmer HXL type pumps are commonly used in refineries, terminal operations, barge and ship loading, and off-loading applications where self-priming and high suction lift capabilities enable them to strip lines clean.
