Goulds Model 3910 for Refinery Services
The 3910 offers inherent in-lineadvantages:
• Lower Installation Costs — No heavy foundation required. • Minimum Floorspace — Ideal for retrofitting and debottlenecking. • Shaft-to-Shaft Alignment — Maintained during changes in nozzle loads or operating conditions (thermal cycling). • In-Line Suction and Discharge Simplifies piping design and construction.

Goulds 3910 is designed to meet the demanding requirements of theHydrocarbon Processing Industries.

3910 Bearing Frame Design for Reliability
Goulds Model 3910 combines in-line and horizontal pump advantages...
• Positive Shaft Alignment — Extended seal and bearing life and reduced vibration. • Proven Shaft Stiffness — Reduced deflection for extended seal life. • Standard Mechanical Seals • Standard Flexible Couplings • Simplified Maintenance — Use of GouldsFramehook™ allows safe and easy maintenance. • Standard Vertical Motors — Power end absorbs all pump hydraulic loads.

BEARING FRAME DESIGN ELIMINATES RIGID COUPLED IN-LINE PROBLEMS:
• Eliminates product lubricated bushings that wear and increase shaft deflection. • Complex rigid coupling assembly and shaft alignment procedures not required. • Special motor designs not required.

GouldsFramehook for Safe and Simple Maintenance
TM

Now there’s a safe and easy way to remove the back pullout assembly for offsite maintenance... without removing the motor or disturbing suction and discharge piping. Goulds Framehook™ facilitates removal (and installation) of the back pull-out. Maintenance personnel can now remove a heavy assembly safely and in minimum time. 1. After removing the casingstud nuts, coupling spacer and any flush or seal piping, position Framehook™ using suitable lifting capability. 2. With Framehook™ bolted in place, separate the assembly from the casing by using the jacking bolts. 3. Lift assembly clear of casing studs. 4. Tilt the unit using threaded adjustment rod for easy removal through opening in motor support. 5. The entire back pull-out assembly ready foroffsite maintenance.
