Finder Pompe Oil and Gas - API 610 and API 685 - VS1-VS6 - HPVT
HPVT are vertically-suspended, multi-stage centrifugal pumps designed and built in full accordance with API 610 norms.
Available either in VS1 or VS6 configurations, depending on the characteristics of the pumped liquid and given conditions of service. Impellers are of centrifugal radial type, closed design with front and back wear rings and balancing holes to provide individual axial thrust balance (standard construction). Rotor axial positioning and support is granted through an oil lubricated double row ball thrust bearing, located on the upper side.
A rigid coupling with spacer allows the removal of the cartridge mechanical seal without interfering with motor positioning and alignment.
Bowls are integrally cast diffuser type to assure optimum hydraulic efficiency and minimum radial thrust under any operating condition. A generously sized, carefully designed line shaft assures rotor stability and low vibration level: shafts are manufactured in one piece for pumps lengths up to 6 m.
Line shaft bearings are normally lubricated by the same pumped fluid and can be provided in different material combinations, depending on the fluid to be handled.
VS6 (vertically suspended, in can construction) is available on low boiling hydrocarbons and condensate extraction services. PED and ASME design and certifications for can, column and discharge head are an available option.
HPVT-DS are designed for higher capacities, with double suction first stage impeller in order to reduce NPSH required and minimize overall pump length in critical suction conditions.
