Sundyne LMV 806 Direct Drive Pump

Safe, reliable and economical the Sundyne API 610, OH3 or OH5, Direct Drive Pump

The Sundyne LMV-806 is an API 610 direct drive centrifugal pump in a standard OH5 configuration or OH3 when used with the bearing frame option. It is also available in the ISO-13709 standard. It is part of Sundyne’s line of direct drive pumps. It fills a gap in the Direct Drive product family by extending the performance envelope to address higher ranges

These vertical inline overhung impeller general service pumps have been deployed by process and rotating equipment engineers for industrial applications in the hydrocarbon, refining, petrochemical, chemical production, oil and gas production, offshore and specialty processing industries. Sundyne pumps are renowned for high suction pressure and a wide range in operating temperatures.

“O” build temperature range 0 to -240°F (115°C) Pressure capability is reduced due to strain hardened pump case studs. Contact Application Engineering.
See Sundyne Corporation exceptions/clarifications to API 610, 11th Edition for material requirements of pump parts.
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.
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.
