Blackmer XL Series
Design Features
The XL pumps are constructed of ductile iron (ASTM 536, 18% Elongation) 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 1.25, 1.5, 2, 3 and 4-inch port sizes with capacities from 5 to 345 gpm (19 to 1,305 lpm). The 1.25 and 1.5-inch models have NPT tapped ports. The 2, 3 and 4-inch models have flanged ports.
?Standard elastomers include FKM O-rings. Optional Buna-N or PTFE elastomers are available. A wide range of mechanical seal components and a variety of vane materials are optional.
The X(R)L1.25 and XL1.5 motor speed pumps are base mounted. The X(R)LF1.25 and XLF1.5 models are fitted with an integral bracket for direct
mounting to a NEMA C-face motor. Base mounted unit assemblies with helical gear reduction drive are available for all XL models.
Application
Blackmer XL type pumps are commonly used in refineries, lube oil plants and general industry for processing, filling and transfer applications.
Benefits
Utilizing Blackmer’s unique sliding vane designs, these positive displacement rotary pumps offer the best combined characteristics of sustained high level
performance, energy efficiency, trouble-free operation and low maintenance cost.
