XL 2-4 Inch Sliding Vane Pumps

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