Reliable direct drive vertical centrifugal pump with an easy to maintain API-682 compliant cartridge seal, OH3 API-610

The Sundyne LMV 801CS is a direct drive centrifugal pump with an API 682 compliant cartridge seal in a standard OH3 API 610 configuration.

The Sundyne LMV 801CS (Cartridge Seal) is a self-contained unit consisting of a shaft sleeve, seal and gland plate that fits onto the pump shaft as a single assembly.  The cartridge seal design eliminates many common causes of seal failure and it helps operators overcome the fitting and installation problems associated with conventional seals.

The compact and rugged API 682 cartridge seal is designed specifically for the Sundyne LMV 801, providing operators and maintenance engineers with an economical alternative to standard seal configurations, in a convenient package that eliminates errors in installation.

- Flows to 380 gpm (86 m³/hr)
- Heads to 720 ft (219 m)

The benefits of Cartridge Seals include:  
  ♦ Faster, easier, and error-free replacement of pump shaft seals

  ♦ The Sundyne LMV-801CS can be installed on any Sundyne LMV-801 without changing the wet end components

  ♦ Eliminates premature failures due to improper installation

  ♦ Less downtime for maintenance

  ♦ Increased durability and reliability

Thousands of extremely reliable and efficient Sundyne LMV 801 centrifugal direct drive pumps are widely utilized to move process liquids and chemicals in various hydrocarbon processing applications including refining, petrochemical and chemical processing facilities. Also, they are commonly utilized in midstream natural gas processing plants and offshore production rigs including FPSO's.

OH3 API-610 ISO 13709 Pumps
The API OH3 is a vertical in-line, single stage, overhung pump with separate bearing brackets. The bearing housing is integral with the pump to help absorb the loads imposed on the pump, and the motor is generally mounted on a support that is also integral with the pump. The pump and motor are coupled with a flexible shaft coupling.
