Sundyne LMV 346 OH6 Integrally Geared Pump

Safe, reliable and economical the Sundyne API 610, OH6, Integrally geared pump

Sundyne API 610, 11th Edition OH6 Integrally Gear Driven Pumps are engineered for critical high-head, low-flow, heavy-duty services required by process and rotating equipment engineers within the hydrocarbon, chemical, petrochemical, power generation, gas production, and specialty processing industries. Sundyne pumps are renowned for high suction pressure and a wide range of operating temperatures.

Unlike conventional multi-stage pumps, Sundyne computer tailored hydraulics place the B.E.P. (best efficiency point) at the rated point resulting in optimum efficiency.  An added benefit is reduced end-of-curve horsepower, allowing for smaller driver sizes resulting in energy savings.

  • Flows to 400 gpm (73 m³/hr)
  • Heads to 6,300 ft (1,348 m)
  • Suction Pressure 1,800 psi (126 kg/cm²)
  • Temperature Range -200 to 650°F (-130 to 340°C)

Multi-stage performance in a single stage pump

The vertical configuration of the integrally geared line of Sundyne pumps is 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. 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.
