The Ultra-Low NPSHr Sundyne API 610 OH3, API 682, ISO 13709, ASME Certified 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 capable of running ultra-low NPSHr <10 ft (3 m) 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 800 gpm (182 m³/hr)
- Heads to 1,030 ft (314 m)
- Suction Pressure 400 psi (28 bar)
- Temperature Range -200 to 400°F (-129 to 204°C)
LOWER INSTALLED COST
Because the LMV-803Lr has such a low NPSHr rating, it may be installed at grade level eliminating the need of a sump pit. This also greatly reduces the required skirt height of an elevated tower significantly reducing typical installed costs.
In addition, 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.

Proven to be reliable, safe, compact and efficient, Sundyne LMV 803Lr pumps provide a number of operational benefits:
- Ultra-low NPSHr, <10 ft. (3m) eliminates the need and expense of pump installation in a pit
- Ultra-low NPSHr significantly reduces the required skirt height of elevated towers
- Single stage, vertical in-line overhung pump compliant with ISO 13709/API 610 OH3/ASME design
- Enhanced throat bushing improves seal performance for light hydrocarbon applications
- Oil mist bearing box design
- Updated cryogenic design for NGL recovery, ethane, and LNG production & storage
- Can be installed at grade level greatly simplifying maintenance compared to BB & VS pumps
- Smaller hydraulic package meets a wider range of process parameters
- Saves space-25% smaller footprint of competing horizontal pumps
- API 682 cartridge seal
- Continuous operation for 5 years with no overhaul
- Proven inducer technology and backswept impeller eliminates low-inlet pressure cavitation.
