XL 2-4 Inch Sliding Vane Pumps Ductile-Iron Pumps for Use in Processing, Filling and Transfer Applications

Designed for use in refineries, lube oil plants and general industry for processing, filling and transfer applications, the XL pump line - which is part of the Iron Line of sliding vane pumps - features replaceable casings, liners and end discs that allow easy rebuilding of the pumping chamber to like-new condition without removing the pump from the piping.

Features and Benefits

  • 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

Applications

  • Refinery applications
  • Lube oil plants
  • General industry
  • Processing applications
  • Filling applications
  • Transfer applications
