Tuthill's process pumps use robust pump design together with tougher, stronger, and more reliable materials to extend the pump’s life.

Tuthill Process Pumps – Built on a time-tested design & more than 90 years of gear pump engineering experience

Capable of tackling the toughest high-viscosity applications, GlobalGear® uses robust pump design together with tougher, stronger, and more reliable materials to extend the pump’s life, reducing total cost of ownership. The result? An unbeatable pump that offers unparalleled performance.

THE PUMP DESIGNED FOR YOU!
Tuthill’s GlobalGear® was developed based on customer input, and customer input in the process industries clearly points to the need for better gear pump reliability and specifically better seal reliability.

  1. STRONG SHAFT DESIGN – Models employ high-strength materials. This, along with oversized diameters, ensures a strong, reliable shaft with less deflection and longer seal life.

  2. 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.

  3. ROBUST BEARINGM – Maintenance free lube for life.

  4. API PLAN 13 – Vent to suction mechanical seal flush.

GLOBALGEAR® Design Features For Extended Seal Life Include:


  • 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

Tuthill Process Pump Package Design

Tuthill designs GlobalGear® pump packages to satisfy a growing customer base of large, international Oil & Gas end users with API 676 standard requirements*. This standard is set forth by the American Petroleum Institute to establish guideline specifications for the use of rotary positive displacement pumps in petroleum, petrochemical, and gas industry services.

Tuthill can offer API 682 mechanical seals for API 676 configured pumps and allowable nozzle loads that are two times or more greater than the minimum allowable nozzle loads specified in API 676. Tuthill also offers the complete package of baseplate, electric motor, gear reducer, coupling, and guard that addresses API 676 features and specifications, along with other project specific requirements.
