Built to comply with stringent API 610 bearing conditions, the 33XN delivers a minimum 3 years MTBF – thus reducing downtime and the need for costly maintenance overhauls.

Sundyne, a leader in the design and manufacture of high head, low flow pumps and compressors for use in the global oil and gas production, refining, petro-chemical and chemical industries, today announced the release of the new Sundyne 33XN gearbox.

A streamlined evolution from the gearbox currently found on Sundyne’s popular line of integrally geared centrifugal pumps and compressors, the new 33XN gearbox is simplified from the casing up to perform better at every level, thus delivering enhanced performance and reliability.

Built to comply with stringent API 610 bearing conditions, the 33XN delivers a minimum 3 years MTBF – thus reducing downtime and the need for costly maintenance overhauls – as well as increased resistance to off-peak or upset conditions. Additionally, with no auxiliary lube pump to specify or maintain, the Sundyne LMX / BMX-33XN gearbox is designed specifically for low to medium power applications, including the difficult to achieve 200-225 horsepower rating, based on Sundyne hydraulics.

Capable of delivering between 150 and 275 horsepower, dependent on configuration, the Sundyne 33XN gearbox features the following design upgrades:

  • Desiccant breather, for preventing excessive moisture build-up within the gearbox;
  • Gearbox output SundSEAL™, which minimizes seal leakage while effectively controlling seal face condition for longer life;
  • A redesigned bearing plate to improve oil path flow;
  • An updated internal lube oil pump that locks securely in place and can tolerate much higher radial shaft loads;
  • And new, more robust anti-friction bearings to increase efficiency and shaft longevity.

The NEW Sundyne 33XN Gearbox is available now.
