That's right, they're finally here!! Introducing our very own, and very kick-ass, all Delrin, high-performance top for use with Laing DDC-series pumps! Designed in-house by our very own Petra (Alex) and machined by the spiffy guys down the street, our DDC top features an internal design which allows for maximum flowrate increase with a minimal loss of maximum head pressure (...and let's not forget all of that sexy, black Delrin ). More performance information about our prototypes (which weren't quite as well contoured, internally, as the final production version) as well as the Radiical and Alphacool (stock & modded) tops can be found HERE. More recent, detailed performance information for the DDCT-01s on various versions of the DDC can be found HERE. Immune to galvanic corrosion, designed in the USA, manufactured in the USA, and backed by Petra'sTech... could things really get any better than that?
The DDCT-01s represents a minor revision of our original DDCT-01 design, providing compatibility with the newer, blue impellered Laing DDC-3 series of pumps that are currently available in Europe. In addition to expanded compatibility, the DDCT-01s also provides slightly improved performance, with slightly reduced power consumption.
