Sundyne LMV 803Lr Ultra-Low NPSHr Direct Drive Pump

The Ultra-Low NPSHr Sundyne API 610, OH3 or OH5, Direct Drive Pump

Sundyne engineers have decades of impeller and inducer design experience. They leveraged that experience and analysis to develop a heavy duty vertical inline centrifugal pump with NPSHr performance that is unparalleled in oil and gas production, midstream and hydrocarbon processing industries. The LMV-803Lr is cabable of running ultra-low NPSHr <5 ft (1.5m) up and down the curve without losing performance.

The LMV-803Lr is Sundyne’s most robust direct drive pump to date.  A rugged 6×4 casing allows for higher pressures and higher flows. The pump features new inducer technology and a backswept impeller that eliminates low-inlet pressure cavitation.

  • Flows to 900 gpm (204 m³/hr)
  • Heads to 1000 ft (305 m)
  • Suction Pressure 525 psi (37 kg/cm²)
  • Temperature Range 0 to 300°F (-18 to 149°C)

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.

The vertical configuration of the direct drive line of Sundyne pumps are specifically designed to save valuable space in refineries, NGL production, petrochemical and chemical plants.

As Required

  1. “O” build temperature range 0 to -240°F (115°C) Pressure capability is reduced due to strain hardened pump case studs. Contact Application Engineering.
  2. See Sundyne Corporation exceptions/clarifications to API 610, 11th Edition for material requirements of pump parts.
  3. Impeller is upgraded to 316SS. A seal gland is not required because the seals mount in the seal housing. O-rings are used instead of a case gasket.
  4. A seal gland is not required because the seals mount in the seal housing. The pump shaft is AISI 4140 because it is not exposed to the fluid. O-rings are used instead of a case gasket.
