Why Choose LMV 803Lr?
Select the LMV 803Lr when you need a compact, heavy-duty pump that runs with ultra-low net positive suction head-under 10 ft (3 m)—throughout its performance range. This means it can be installed at grade without a suction pit or elevated tower , cutting installation costs and simplifying maintenance in oil & gas , petrochemical , LNG, and water services. Industry-standard API 610 OH3 design ensures robust reliability
Main Features
Direct-drive vertical inline design (API 610 OH3/OH5) using innovative inducer and backswept impeller for risk-free low-inlet-pressure operation.
Rugged 6″×4″ casing rated to 1,000 psig, sized 25% smaller than typical horizontal competitors .
API 682 cartridge seal, oil-mist bearing box standard (grease option), and updated throat-bushing for light hydrocarbon compatibility .
Cryogenic design version supports NGL, ethane, and LNG applications with confidence .
Compact vertical layout saves space and may eliminate the need for cranes or pits during maintenance .
Applications
Widely used in critical services such as:
Feed, booster, reflux, bottoms, and fractionation duties
Bubble-point or NGL pumping without cavitation concerns
LNG, ethane, and cryogenic fluid services
Wash-water, condensate, and boiler-feed pumps
Suitable for seawater or vapour-liquid processes .
Choose the LMV 803Lr for its ultra-low suction requirements, compact footprint, and heavy-duty reliability. Designed to API 610 standards and proven in hydrocarbon and cryogenic services, this pump saves space, eliminates tricky installations, and boosts plant uptime—while still fitting into existing LMV configurations with global support.
