HXLJ Jacketed Sliding Vane Pumps Featuring Heat Jackets for Use in high-viscous and high-temperature applications

Utilizing the unique Blackmer® sliding vane design, these Heavy Duty Line positive displacement rotary pumps offer the best combined characteristics of sustained high level performance, energy efficiency, trouble-free operation and low maintenance cost.

The HXLJ8 model features jacketed heads for high-viscous and high-temperature applications. Base-mounted unit assemblies with commercial gear reduction drives are available for all HXL models. This model is fitted with replaceable casing liners and end discs that allow easy rebuilding of the pump, without removing the pump from the piping. The jacketed model is available in 8-in ANSI flanged port sizes with a maximum rated capacity of 1,228 gpm (279 m3/h). Standard elastomers include FKM O-rings. Optional bolt-on relief valves are designed to protect the pump from excessive pressure are available for all sizes.

Features and Benefits

  • Ductile-iron construction with bolt on, internal relief valve
  • Internal mechanical seals have reduced speeds, allowing for extended dry run without failure and continuous operation with non-lubricating liquids
  • Replaceable casing liners and end discs allow easy rebuilding of the pumping chamber to like-new condition without removing the pump from the piping
  • High volumetric efficiency and symmetrical bearing support means less required horsepower than other PD pumps, meaning a cost savings on both motor operation and electricity
  • 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
