The DW series is superseded entirely by the SumPro series. In the new documentation only the new models will be presented and quoted for.
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.

Tip: when replacement  pumps are required for older pump models you have to realise that these pumps have evaluated over time in efficiency. So a 1:1 exchange will probably lead to a much higher capacity than expected with the risk of too high suction line velocities etc. We recommend to always recalculate new replacement pumps against the actual process requirements. Please contact us in case of doubt. Calculate with 1 m/sec max suction line speed to be on the safe side.

Our new general catalog of ARBO is ready in 3 languages: EN-DE and NL.
The new design incorporates the update of technical details and added shipping information, like weights and box sizes. In printed format we only offer the complete set*) of documentation. Every single brochure is available in digital format in low resolution via the website.

In April we signed a distributor contract with Tapflo Danmark SpA. Flemming Ravn Sorensen is co-owner of this company within the Tapflo Group and very experienced in the sales of pumps.

In the new documentation we do not mention in general old models any longer. In the sealless immersible product range (3.0) the DO-DW series has been replaced and is part of the SumPro product range. There is still a limited amount of stock of parts to support the after sales. If you need to replace a DO-DW pump, please contact us and we have clear substitution tables available to help you with dimensions and connection sizes.
