The BS vertical centrifugal pumps, made in 6 sizes and in 9 versions, are designed with a completely cantilever shaft in standard lengths, without mechanical seals or guide bushes.
A double-acting impeller dynamically ensures the hydraulic seal of the liquid.
The absence of sliding parts makes these pumps particularly suitable for the handling of liquids with suspended particles, with the tendency to form incrustations or to crystallise, or in any case when the wear risk may influence the life-span of the pump.
