Tuthill Global Gear Series

Global Gear was introduced in 2001, and since then more than 12,000 pumps have been shipped to locations all over the world. The Inside Reliability Story Behind GLOBALGEAR®

Tuthill’s Global Gear® 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.

Tuthill Global Gear Series Performance Capabilities

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.

Design features for extended seal life include:

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