OTHER FEATURES & BENEFITS
Back Pull-Out Design
• Reduce downtime for service
• Maintain pump without disturbing piping or shaft alignment
Customized Options
• Relief valve
• A variety of seal choices
• Oversized and high-pressure flanges
• Tutriding process to harden surface of pump to resist abrasion, fatigue, and limit crack propagation
• Specialized construction for high temperatures
• Modular port options
• Jacketing
Design Features Extend Seal Life
• Oversized shaft and bearing diameters on models GG130–GG550 to minimize shaft deflection
• Large bore size for stuffing boxes for improved fluid circulation
