The number of types has expanded and we made a split between the plastic – and Stainless Steel variants of the same pump models. They are called “Stainless” which does not mean that they are only available in standard Stainless Steel qualities. On request also high grade Stainless, like Hastelloy is available

Within this series a number of variants is now available for 2900 min-1. Heavy duty bearing assemblies are developed which makes the use of higher motor powers possible.HD series

In the product portfolio and PumpFlo a new VX variant is available.
VX means Vortex, indicating that the pump has a vortex housing and a turbine impeller. This combination makes it possible to pump liquids with solids up to 32 mm without problem!

The capacity curves are quite similar to the existing types, but the consequence of larger particle ability is a fractional lower efficiency.  
Basically the Vortex execution is available on all ARBO pump series.
