Blackmer XLW 600 Pump

XLW Sliding Vane Pumps Ductile-Iron Pump Capable of Handling Liquids with Suspended Particles

Blackmer® XLW Ductile Iron Pumps, part of the Heavy Duty Line of sliding vane pumps, are specially designed to handle liquids with suspended abrasive particles and are constructed with hardened and replaceable wear surfaces (liners and end discs) for extended service life. The XLW is capable of handling liquids with suspended particles up to 250 microns and 25% concentration. 

Utilizing unique Blackmer 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.

Blackmer fully Integrated Unit Assemblies are the pre-engineered and pre-designed drop-in pumping solution. These unit assemblies, include motor, gearbox, baseplate, coupling safety covers, and a XLW Sliding Vane Pump (2, 3 & 4-inch size). No alignment required with these pre-configured fully Integrated Unit Assemblies as they are ready for immediate drop-in installation.

Features and Benefits

  • Replaceable casing, liners and end discs that allow easy rebuilding of the pumping chamber to like-new condition without removing the pump from the piping
  • Hardened ductile-iron construction with internal relief valve
  • Blackmer mechanical seal and ball bearing construction provide maximum reliability
  • Symmetrical bearing support assures even loading and wear for long life
  • Adjustable relief valve protects pump against excessive pressures
  • External ball bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk
  • Advantages of sliding vane technology:
    • Unique sliding-vane pump design self-adjusts for wear to maintain flow rates
    • Excellent self-priming and dry-run capabilities
    • Sliding vane design provides sustained performance and trouble-free operation
    • Easy maintenance: vanes can be easily replaced without removing the pump from the piping system
    • High suction lift and line-stripping capabilities
    • Low maintenance and low life-cycle costs
