Global Gear Pumps
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 for viscous liquids are fundamentally designed for packing and later adapted to mechanical seals.
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
