Text Box: API 610 VS1 / VS6
National Vertical Turbine Pumps

VS1 / VS6 Series features include:

Compliant with API 610 current edition.

Multi-staging in the medium specific speed range from 1,300 Ns through 5,000 Ns.

High pressures with premium efficiencies and low operating costs.

Low NPSH first stage construction with Nss below 11,000 is available which allows for a reduction in can length for double casing pumps (VS6) and minimum submergence for wet pit single casing pumps (VS1).

Pressure and flow variations are achieved by changing number of stages or impeller type.

Pump bowl assembly is characterized as low energy per stage resulting in a broad flow range with excellent hydraulic stability.

Thrust balanced impellers are available for pump axial thrust reduction and assist in obtaining the desired thrust bearing rating/life.

Thrust pot assembly is available in applications where non-thrust carrying motors are required.
