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.

The DW series is superseded entirely by the SumPro series. In the new documentation only the new models will be presented and quoted for.pumps
For after sales on existing projects we have 100% exchangeable types available. As an example:

for the DO-100-DW we offer the DO-32-125
for the DO-300/400 we offer the DO-50-125.
Between the SumPro and HD series there was a gap which now has been filled with the new SumPro DO 40-160 and DO-50-160 models which can be equipped with motors up to 5,5 KW max. This expansion in the SumPro makes smaller ranges in the HD series obsolete.
For the DO-HD new IE2 and IE3 motors are available in 5,5 and 7,5 KW with extended shafts.
