Unboxed: JECOD (Jebao) DCT4000 Return Pump

In case you haven’t heard, Jebao are changing their name to JECOD (which stands for Jebao ECOlogical Design). All new UK products will have this branding, and first to reach us are the new DCT series of pumps which replaced the previous DC series late last year. In this unboxing review we take a preliminary look at the DCT4000 model and evaluate the range overall in terms of quality,  performance on paper and features.

Looking almost identical to the older DC series (with the new DCTs grey, and the older DC series blue) you might wonder what exactly makes these pumps ‘new and improved’ as overall they do appear to be very similar. On this subject, we are reliably informed that, rather than featuring the 2 phase 4 pole motors and hall effect sensors of IMG_4645webthe DC pumps (and WP/RW pumps), the new DCT pumps feature new 3 phase 6 pole sensorless motors. This basically means that in the DCT pumps, the control electronics have been moved from the pump into the controller itself. This should result in greater reliability as an electronic failure should only require a controller change rather than a whole pump motor. There’s been the odd comment online about the DCT series not being compatible with the Apex system, unlike the older DC series, but we believe that neither the DC or DCT pumps were designed to be Apex compatible. With PWM used to control the speed though, it is technically possible that they could be controlled by Apex, if a suitable interface is designed.

Looking at the feature-set we can immediately see that the DCT range offers a redesigned 10 speed controller which allows each pump to be dialled well back from the max flow rates (see table below). Retaining the soft start mechanism and the dry running/blocked rotor auto-shut-off system of the older DC pumps, the DCT now adds a visible indication/warning system through this controller. As well as providing extended control over the pump output level, the controller allows for selection of a 10 minute ‘feed mode’ and, as said, provides an extensive visual fault alarm system. Take note that pump settings should also be stored in the event of a power outage so it won’t come back on at a power level higher than you’ve chosen. The pump itself has a ceramic shaft and excludes copper components, so this range (like the older one) is suitable for saltwater or freshwater applications. Of course this is an internal only pump. Units in the range, along with dimensions and ‘real life power/flow measurements’ are as follows:

DCT 4000 – 13.6cm x 8.0cm x 10.7cm
1920 – 4000lph 30w 3.0m Max head RRP £82

DCT 6000 – 16.5cm x 10.4cm x 12.8cm
2880 – 6000lph 42w 3.8m Max head RRP £125

DCT 8000 – 18.2cm x 10.4cm x 12.8cm
2480 – 8000lph 70w 4.5m Max head RRP £135

DCT 12000 – 18.2cm x 10.4cm x 12.8cm
3720 – 12000lph 85w 5m Max head RRP £145

DCT 15000 – 21.5cm x 12.6cm x 15.8cm
n/a* – 15000lph 100w 5m Max head RRP TBA (but close to £190)

(*note: the DCT1500 has a different controller and power settings have not yet been verified – this model is due into the UK in a couple of weeks)

Obtaining our unit from exclusive UK-based trade distributor and site sponsor Simply Aquaria, it arrived promptly, well-packaged with a UK plug as standard (we were also extremely impressed by the support we received from SimplyAquaria, and their knowledge of the product is clearly excellent!). Also included in the box are a range of different fittings which include essentials like an intake strainer and hose attachments. All components appear of reasonable quality and durability on first impressions.

So, that’s it for now! Keep an eye on the blog as we’ll be running an operational test of this unit on our new test system in the coming weeks which as usual will include a more detailed evaluation on the units actual power consumption, noise and heat generation, reliability, functionality and more. We’ll hopefully also be taking a look at the rebranded RW series circulation pumps which are currently slated for mid-March arrival.
