DK20
Buying DK20 from Flexa Systems
Buy the Gerwah DK20 motor, in stock refurbished with brand new available on request, or send yours to Flexa Systems for repair. Its listed dimensions are 8mm x 9.5mm bores with a 25mm OD, so a replacement has to match both bore sizes and the outer diameter to fit the same shafts and envelope as the unit coming out. Check those three figures against the markings on your existing DK20 before ordering, because a mismatch at either bore means it will not seat on the shafts already in the machine. Each refurbished DK20 is tested before shipping, carries a 2-year warranty and typically costs 30-60% less than new.
Repair option: component-level repair is available for this model — free diagnostics, a 2-year warranty, and a 5–30 business day turnaround. Repair typically costs 40–70% of a new unit, saving you 30–60%. Request a repair quote.

DK20 FAQ
What should I match before swapping in a Gerwah DK20?
Compare the 8mm and 9.5mm bores and the 25mm OD with the rating plate or markings on your current unit. Both bores and the outer diameter must line up for the DK20 to fit your existing shafts and mounting space.
Is a refurbished DK20 a good alternative to a brand new one?
Refurbished DK20 units are in stock and tested before shipping, which makes them the faster route. Brand new is available on request if your specification requires an unused part.
