The Sundyne LMV-803Lr is an API 610 compliant, OH3 or OH5 type pump for ultra-low NPSHr pump applications.

Ultra-Low NPSHr Pump:
Multiple decades of inducer design experience are coupled with state-of-the-art design and analysis to bring NPSHr down on the LMV-803Lr to unparalleled levels: approximately 5 ft (1.5m) up and down the curve without losing NPSHr performance.

  ♦ Flows to 800 gpm (180 m3/hr)
  ♦ Heads to 1,000 ft (305m).

The LMV-803Lr is Sundyne’s most robust direct drive pump to date.  A rugged 6x4 casing allows for higher pressures and higher flows.  The pump features new inducer technology and a backswept impeller that eliminates low-inlet pressure cavitation.

Direct Drive Pump Applications:
The vertical configuration of the direct drive line of Sundyne pumps are specifically designed to save valuable space in refineries, NGL, petrochemical and chemical plants.  They are designed to be used as:

  ♦ Feed pumps
  ♦ Booster pumps
  ♦ Bottoms pumps
  ♦ Wash water pumps
  ♦ Reflux pumps
  ♦ Condensate pumps

Installed Cost Benefit:
Available as either an API OH3 or API OH5 type pump, the LMV-803Lr can be installed at grade level, eliminating the need and expense of pump installation in a pit or construction of a tall distillation tower to provide ample head.
