The Sundyne Ultra Low NPSHr LMV 803Lr centrifugal API-610 OH3 and OH5 pump. Built with a new 6x4 casing design to withstand high pressure applications in the midstream and downstream industries. Rugged reliability with a small vertical footprint.

The LMV-803Lr is the high head - high flow, ultra low NPSHr (less then 5 feet, 1.2 meters) centrifugal vertical pump that Sundyne is known for in the midstream and downstream oil and gas industries. The ultra low NPSHr pump features industry leading Sundyne inducer technology and a backswept impeller that eliminates low-inlet pressure cavitation.

The LMV-803Lr is ideal for use as a booster or fractionation bottom pump in midstream LNG processing, as well as for pumping seawater or condensate truck loading. 

Models are available in OH3 and OH5 standards and are fully compliant with API 610 A-8 guidelines. The LMV-803Lr also boasts a robust new 6x4 casing design that is built to withstand high pressure applications. As with the decades old Sundyne tradition, the ultra low NPSHr pump brings the compact footprint, up time reliability and optimized efficiency of this workhorse technology to your high pressure, high flow application.
