Sundyne LMV 801CS Direct Drive Pump

Safe, reliable and economical the Sundyne API 610, OH3 or OH5, with Cartridge Seal API-682 Direct Drive Pump

The Sundyne LMV 801CS (Cartridge Seal) is a self-contained unit consisting of a shaft sleeve, seal and gland plate that fits onto the pump shaft as a single assembly.  The cartridge seal design eliminates many common causes of seal failure and it helps operators overcome the fitting and installation problems associated with conventional seals.

The compact and rugged API 682 cartridge seal is designed specifically for the Sundyne LMV 801, providing operators and maintenance engineers with an economical alternative to standard seal configurations, in a convenient package that eliminates errors in installation.

  • Flows to 380 gpm (86 m³/hr)
  • Heads to 720 ft (219 m)
  • Suction Pressure 1,000 psi (71 kg/cm²)
  • Temperature Range -200 to 650°F (-130 to 340°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.

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.
