Why Choose VS6?
The VS6 combines the benefits of a diffuser-style hydraulic design with a robust double-casing structure, making it ideal for high-pressure, high-flow wet-pit environments. Designed to API 610 11th Edition and ISO 13709 standards, it effectively increases NPSH and protects against leaks. With discharge routed through the shaft column, it delivers reliability in critical applications from sump pumping to pit drainage—while meeting petrochemical, desalination, and refining demands
Main Features
Double-pressure casing encloses the submerged bowl, eliminating the need for an open sump .
Diffuser-type hydraulics convert velocity into pressure across multiple stacked stages
Rodelta
Radial-split casing, permitting inline removal of the rotating column without disturbing pipework
Column discharge configuration, where flow is directed up through the shaft column—simplifying installation
Seal chamber per API 682 enables reliable single or tandem mechanical seal configurations
Applications
Ideal for demanding services including:
Desalination plant sumps
Tank-farm drainage and transfer
Warehouse and refinery wet-pit utility pumps
Plant condensate extraction
Offshore/in-plant sump installations and wet-basin chemicals
Choose the VS6 – Its double-casing design boosts NPSH and protects oil systems, while diffuser hydraulics and vertical discharge provide smooth, efficient flow. Built to API 610 standards and supported by Sundyne’s global service network, the VS6 excels at delivering clean, powerful pit pumping in the toughest environments.
