Sundyne LMV 801S Sealless Magnetic Drive API 685 Pump

SundyneSealless Magnetic Drive API 685 Pump – Safe, Reliable and Economical

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.

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.

  • Flows to 380 gpm (86 m³/hr)
  • Heads to 720 ft (220 m)
  • Temperature Range -40 to 400°F (-40 to 205°C)

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.
