The Sundyne LMV-801S is an API-685, vertical inline, single stage, overhung sealless magnetic drive pump ideally suited for high-head, low-flow liquids.

The Sundyne LMV-801S is an API-685, vertical inline, single stage, overhung sealless magnetic drive pump that is ideally suited for high-head, low-flow liquids required in today’s refinery processing, chemical processing and midstream industry services.  The LMV-801S is part of Sundyne’s direct-drive line of pumps that offers reliable performance in a compact vertical design.  

Combining Proven Sundyne Hydraulics with Pioneering Magnetic Drive Technology:
The LMV-801S combines the industry standard hydraulics of the Sundyne direct-drive line of pumps with the magnetic drive technology pioneered by Sundyne HMD/Kontro more than 70 years ago.  It is built to comply with both API-685 and API-610 standards, and is specifically engineered to eliminate emissions and improve personnel safety without compromising the time-proven production hydraulics of Sundyne direct-drive pumps.   

Proven Performance Coverage:
The LMV-801S sealless pump utilizes the same hydraulics as the traditional line of LMV-801 direct-drive pumps – making it easy to upgrade to a safe sealless pump design, or commission new units without compromising existing production.

   ♦ Flows to 380 gpm (86 m³/hr)

   ♦ Heads to 720 ft (220m)

Worry-Free Conversion:
The LMV-801S is dimensionally interchangeable with the traditional mechanically sealed LMV-801 (OH3/5), and can be easily dropped into existing pipework - making this sealless upgrade possible without the need to modify piping and foundation layouts.  Additionally, a plug-in version of the pump is available, enabling customers to swap out the mechanical seal drive end with the new sealless option without disconnecting the existing LMV-801 casing and diffuser from the piping.

Benefits:
The LMV-801S delivers maximized up-time, reduced maintenance costs and optimized productivity over the lifecycle of the unit.  Its sealless design offers no seals that leak, making it safe and reliable for handling hazardous liquids.  

Customers in the oil refining and petrochemical industries rely on Sundyne pumps for their high-head, low-flow capabilities, and for their ability to safely handle difficult or hazardous applications.  The LMV-801S provides the benefits of a sealless pump, the reliability of Sundyne hydraulics all in a compact package.
