The VS6 Type ring section impeller is ideal for pumping fluids at medium and high pressures.
The FGB/TKVB pumps are ideal for pumping fluids at medium and high pressures. They are manufactured in materials selected for each particular application, all included within table H1 of the API 610 standard. Manufacturing processes guarantee the highest quality level and include rotor dynamic balance, hydrostatic and performances tests, measuring flow, head efficiency, NPSH, vibrations and the most rigorous quality control. Multistage centrifugal pumps up to 14 stages (standard construction), mounted in series separated and placed into perpendicular elements to the shaft rotation.
