Principle

These pumps can handle virtually any fluid, regardless of viscosity, lubricity or abrasiveness e.g. seawater, bitumen, molasses, lime, acid, caustic solution or hydrocarbon.

The W-range is a horizontal pump execution with external bearings. We distinguish from the short execution (Wzk) and the long pump execution (Wz). The short execution will be used for applications with high differential pressures. Due to the low space for the mechanical seals the choice of the seals is limited.
