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.
