GlobalGear® Pumps tackle the toughest high-viscosity applications

Tuthill Global Gear Series of Process Pumps are a preferred solution to support lubrication applications in large natural gas compressors.


  • Strong Shaft Design – all models employ high-strength materials. This, along with oversized diameters, ensures a strong, reliable shaft with less deflection and longer seal life.
  • Tough Gears – The rotor and idler gears are made of tough materials, which can handle the stresses of high-viscosity and high-pressure operation. No need for steel rotor upgrade.
  • Robust Bearing – Maintenance-Free lube for life.
  • API Plan 13 – Vent to suction mechanical seal flush.

Designed for Extended Seal Life:

  • Oversized Shaft & Bearing Diameters on Models GG130 – GG550
  • Large Bore Size for Stuffing Boxes
  • Pressurized Fluid Paths for Seal Lubrication
  • Options for Viscous Liquid Duty Seals
  • In-Line Seal Maintenance
TuffSeal™ Heavy-Duty Slurry Seal
