Wi+ inducer pumps boost the inlet pressure, which helps reduce the risk of cavitation as the required NPSH drops by around 50% to 70%. When this risk is eliminated, so is the risk of a number of operational disturbances that would otherwise be a concern: energy loss, damage, pump wear and tear, excessive noise, etc. A common problem in some applications, such as processes with vacuum requirements, is a low section head.
Since the NPSH requirements are kept to a minimum, the WI+ is distinguished among inducer pumps. The pump is further enabled by the inducer to handle gaseous or viscous products that other centrifugal pumps would not be able to handle.
