Sundyne: New low NPSHr, high-flow pump


sundyneThe Sundyne LMV-803Lr is an API 610 compliant pump available in either OH3 or OH5 motor mounting configuration that provides ultra-low NPSHr performance – approximately 5 ft (1.5 m), across the entire performance range – for flows to 800 GPM (180 m³ / hr) and heads to 1,000 ft (305 m).

The ultra-low NPSHr allows the pump to be installed at grade level, eliminating the expense of installation in a pit and performing maintenance in a confined space. The vertical design is ideal for use in refineries, NGL, petrochemical and chemical plants, as well as handling light hydrocarbon handling services, such as bottom pumps for de-ethanizers.

Based on a direct drive technology, the LMV-803Lr is  a rugged pump, delivering

  • a compact footprint,
  • low vibration and
  • increased efficiency.

Featuring innovative Sundyne inducer technology and a newly redesigned backswept impeller, this model is capable of meeting lower NPSHr requirements than either BB2 or VS style pumps without risk of cavitation. The LMV-803Lr also boasts a robust new 6×4 casing that is engineered to operate reliability in extremely high-pressure applications with maximum case working pressures equivalent to 1,000 psig (70 kg / cm²).
