ARVADA -- Sundyne, a global leader in the design and manufacture of API-compliant centrifugal pumps and integrally-geared compressors today announced a series of enhancements to the LMV 803Lr high-flow pump designed to deliver ultra-low NPSHr performance while reducing installation and maintenance costs.Sundyne_logoUSE 

The API-compliant LMV 803Lr is a direct-drive, heavy duty vertical inline centrifugal pump that shares technology with Sundyne’s legendary 800-series pumps, which are widely used in the oil & gas, refining and hydrocarbon processing industries.

The design of the LMV 803Lr features Sundyne’s innovative inducer technology and backswept impeller, which allows the pump to reach unparalleled NPSHr performance (less than 10 ft/3m up-and-down the curve) without the risk of cavitation.

Updates announced today improve the LMV 803Lr pump in the following areas:

  • An enhanced throat bushing improves seal performance for light hydrocarbon applications. This facilitates API 682 seal chamber compliance utilizing existing castings with a consistent footprint.
  • A new oil mist bearing box (which comes standard) complies with API 610 requirements and offers more robust loading capabilities, reducing the need for periodic greasing. A grease lubricated bearing box is also available.
  • An updated cryogenic design for NGL recovery, ethane, and LNG production & storage applications.
  • An expanded hydraulic package meets a wider range of process parameters and delivers ultra-low NPSHr up-and-down the curve. The total size of the LMV 803Lr is just 25-percent as large as competitive horizontal pumps. This small footprint reduces service & maintenance costs, because in many instances a crane is not required to install and maintain the pump.

“The LMV 803Lr can be installed at grade level, which enables operators to meet their NPSHr requirements without a sump pit, or elevated tower skirt,” said Helene Balligand, Sundyne’s product line manager.

“By eliminating the need to install pumps below grade, or lift vessels to attain NPSHr, plants can save tens-of-thousands of dollars on installation costs, while simplifying maintenance and streamlining operating costs over the life of the pump.”

Sundyne said the latest enhancements to the LMV 803Lr make the pump ideally suited for low NPSHr processes that require booster pumps, LNG processing & storage applications, bubble point light-hydrocarbon applications, or downstream refining applications such as fractionation.

The LMV 803Lr is also used in industrial applications, such as boiler feed, or seawater applications.
