Sundyne LMV 801S Sealless Magnetic Drive API 685 Pump

Sundyne Sealless 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.

O-rings

As Required

  1. “O” build temperature range 0 to -240°F (115°C) Pressure capability is reduced due to strain hardened pump case studs. Contact Application Engineering.
  2. See Sundyne Corporation exceptions/clarifications to API 610, 11th Edition for material requirements of pump parts.
  3. Impeller is upgraded to 316SS. A seal gland is not required because the seals mount in the seal housing. O-rings are used instead of a case gasket.
  4. A seal gland is not required because the seals mount in the seal housing. The pump shaft is AISI 4140 because it is not exposed to the fluid. O-rings are used instead of a case gasket.
  5. Diffuser Inserts and Diffuser Covers apply to model LMV-801 only.

POWER MONITOR

Installed in the Motor Control Center (MCC), a power monitor measures the power required to operate the pump.  By setting High and Low trip points, the power monitor is the perfect solution for protecting your pump from:

  • Dry running
  • Low flow operation
  • High flow operation
  • Severe cavitation
  • Magnet de-coupling

New ZeroLoss™ Containment Shell

Reduces Power Losses in the Pump to Zero

  • Excellent energy savings can now be made thanks to the introduction of the ZeroLoss containment shell for larger pumps. The elimination of eddy current losses can result in up to a 20% saving in power consumption, further enhancing the benefits and green credentials of magnetic drive technology from Sundyne HMD Kontro.
  • The advantage increases in proportion with the magnetic coupling size and is particularly appropriate for larger pumps, making the magnetic drive option even more attractive because through life costs are reduced further. Lower powerconsumption not only results in reduced running costs but alsopotentially provides lower initial capital costs, as smaller motors can be specified.
  • In addition, installation costs can be reduced as lower-rated cabling may be required, and there are space-savings from the ability to use a smaller base plate for the pump and motor combination.

VapourView® Ultrasonic Monitor

A gas detection system designed to bolster the reliability and eliminate dry-running of HMD Kontro API-685 Sealless magnetic drive pumps. This warning system mitigates costly pump component replacements and downtime that can result from dry running, entrainment or cavitation.

The VapourView is powered by an industry standard 24 Vdc supply and returns a 4-20 mA signal suitable for monitoring using a distributed control system (DCS). It features both light emitting diode (LED) and liquid crystal displays (LCD) to provide information on process fluid conditions inside of the pump to process engineers.

The VapourView has been performance tested and is compliant with explosive atmosphere and electro-magnetic compatibility requirements.The VapourView non-intrusive gas-in-liquid detector can be easily retrofitted into any HMD Kontro API 685 pump and will operate at temperatures between -40 and +350 degrees F (-40 and +180 degrees C).

LONG COUPLED

Long coupled configurations conform to API 685, API 610, ASME/ANSI B73.3 and ISO 2858 dimensions for easy replacement of mechanically sealed pumps (utilizing same baseplate, coupling, guard and motor).

SECONDARY CONTROL & CONTAINMENT

HMD Kontro Sealless magnetic drive pumps are available with secondary control devices to restrict any leaks. Mechanical devices are fitted to the drive shaft assembly and are activated in the unlikely event of containment shell failure. Also, the pump coupling housing is fitted with gaskets to eliminate any leaks across the joining faces.

Solids Handling

All HMD Kontro pumps, as standard, can handle up to 5% hardsolids and 150 microns diameter. The solid size can increase by fitting a self-cleaning in line filter, to 8% solids and 250 microns.

For larger solids HMD Kontro can provide pumps with a clean flush system or filter built into the flush pipework.
