Sundyne's New 33XN Gearbox Conversion Offers a Simple and Straightforward Upgrade for LMV 31X Pumps
ARVADA, Colo., Aug. 17, 2020 /PRNewswire-PRWeb/ -- Sundyne, a global leader in the design and manufacture of API compliant pumps and compressors for the oil & gas, refining, power generation, chemical and water treatment industries, today announced a simple upgrade for LMV 31X pumps with the introduction of the LMV 33XN Gearbox Conversion. The new LMV 33XN gearbox features a robust design that is capable of handling higher loads and tougher process conditions, while also extending mean time between maintenance intervals.
This new upgrade is offered as an easy, interchangeable, bolt-on solution that can be delivered to customers quickly. Sundyne's LMV 31X pumps have been deployed for decades - and this upgrade targets existing LMV 31X pumps that are approaching an overhaul, or for units that are not meeting newly expanded MBTM expectations.
"Process conditions in plants serving the energy, chemical and power industries are changing, and every operator seeks greater efficiency, better reliability and decreased maintenance costs via extended MBTM intervals," said Sundyne's Aftermarket Product Manager Donald de Regnier. "Our new gearbox upgrade provides a bigger idler shaft with stronger gear sets that can handle higher loads, and it also extends the bearing life three-times longer than the existing LMV 31X offering."
Sundyne's new gearbox upgrade offers the following ten improvements:
1. Enhanced labyrinth/face input shaft seal - reduces oil misting, shaft
wear and gearbox contamination.
2. Improved spherical roller bearings (idler shaft) - the L10 bearing life
of 25,000 hours at rated point is three times greater than the bearings
used in a 31X gearbox. This upgraded design provides significantly higher
radial and axial loading capacity.
3. New helical upper mesh gears - handle the highest levels of loading in
the entire gearbox. The new helical teeth provide 3 points of contact at
all times (as opposed to straight teeth with one point of continuous
contact). A 59% increase in gear thickness significantly increases the
load capacity over a 31X gearbox.
4. New bolt-in, unidirectional internal lube pump - increases capacity to
provide 12% more oil flow.
5. Improved oil fill & reserves - ensures lubrication of thrust and journal
bearings prior to start up.
6. No auxiliary lube pump is required - for more than 90% of applications.
7. Increased shaft diameter - offers greater load capacity and decreased
deflection at gear teeth.
8. Lower mesh gears - are now 49% thicker than LMV 311 for increased load
handling.
9. Lower idler bearing - new hydrodynamic bearings improve life & load
capacity.
10. Splined impeller connection - provides superior torque distribution to
combat shaft fatigue.
