L Series Lobe Pumps L80

The Ebsray® Model L80 Lobe Pump is designed and precision built for efficient transfer of medium to high viscosity clean liquids. It is a highly-efficient positive displacement rotary lobe pump that has only two moving parts to perform its pumping cycle. This lobe pump is especially suited for high viscosity liquids where increased efficiency is demanded, such as applications in the chemical, oil, paint, bitumen, resin, petrochemical and sugar industries.

Features and Benefits

  • Mechanical seal/hydraulic packing
  • Heating/cooling jackets
  • Reversible rotation and flow
  • Integral bypass/pressure relief valve - optional
  • Heavy-duty design
  • High overall efficiency at high viscosities
  • Self-priming, positive displacement
  • Low maintenance - long life, since lobe pump has only two rotating elements
  • Robust construction for heavy-duty applications
