Tuthill Global Gear Process Pumps

Tuthill Global Gear Pumps
Tough Pumps with Field Proven Reliability

Fluid Engineering is pleased to represent Tuthill and its Global Gear line of internal gear process pumps. 

GlobalGear® builds on a time-tested design and more than 80 years of gear pump engineering experience. Capable of tackling the toughest highviscosity applications, the GlobalGear® Process Pump handles everything from bulk transfer, chocolate and asphalt, to hightemperature fluids and chemical processing.

GlobalGear® uses robust pump design together with tougher and stronger materials to make the pump last longer. When maintenance is required, in-line seal maintenance and back pull-out features are available to make the servicing of the pumps quicker and easier. The result? An unbeatable pump that offers unparalleled performance.

The Inside Reliability Story Behind GLOBALGEAR®
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. The opportunity for better reliability is created by the situation that many pumps applied on viscous liquids are fundamentally designed for packing and later adapted to mechanical seals. In many cases, the seals being selected were designed for use with water-like liquids. Pumps designed for packing combined with mechanical seals designed for thin liquids are no match to offer extended reliability with demanding viscous liquid applications.

GlobalGear® design features for extended seal life include:

  • Oversized shaft and bearing diameters in sizes 120 thru 550
  • Large bore size for stuffing boxes
  • Pressurized fluid paths for seal lubrication
  • Options for viscous liquid duty seals

GlobalGear® Materials and Size Address a WIDER RANGE OF APPLICATIONS.
GlobalGear® pumps are available in nominal flows of 15 to 550 gpm at pressures up to 200 PSI.


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.

Revolutionary lubrication method extends overall life by reducing friction.

Models employ high-strength shaft materials. This, along with oversized shaft diameters, ensures a strong, reliable shaft.

Maintenance Free.
Lube for Life.

Introducing the HG VERSION GLOBALGEAR®, for the toughest of tough services.
THE CHALLENGE…Provide a pump that will:


  • Handle side loads of belt drive and allow for the sheave to be mounted directly on the pump input shaft
  • Handle thrust loads associated with high system pressure
  • Handle cold starts where the temperature drops to minus 20°F
  • Withstand operation in a high vibration environment
  • Design for five year life with only scheduled preventative maintenance lubrication

Tuthill answers with the HG set of severe services upgrades:

  • Interference fit, paired single row bearings capable of 80,000 hours B-10 life
  • Heavy duty hard face slurry type seals
  • Extra shaft length to accommodate belt sheave
  • Cartridge style drive module for bearing and seal renewal in minutes by a non-specialized crew

The back pull-out design greatly reduces down-time for service – the pump can be repaired without disturbing piping or shaft alignment.

GlobalGear was introduced in 2001, and since then more than 9,000 pumps have been shipped to locations all over the world.
