Finally we had in our hands on an adjustable return pump with great characteristics for a marine aquariums: the ASF Aquarium Systems NewJet DC 2000. You’ll see its great performances in in our tests.

Aquarium Systems has a great experience in the construction of centrifugal pumps, and now we’re glad to have for us the new ASF NewJet DC 2000. It’s an adjustable return pump that works at 24V and it has great technical features that could make it chosen as return pump for a lot of marine aquariums. The pump is easily recognizable because of the livery, in which the base and the rubber holder rings are fuchsia. The pump is in dotation with two rubber holder of different diameters. Please remember, NEVER USE the smaller rubber holder. Read this article for the reason: How to save electric power in marine aquarium: the return pipe.
The pump is an AC centrifugal pump, but it works also at adjustable low voltage. We measured, as usual, hydraulic head, flow rate and power consumption.
For the head we used our usual static method. For the flow rate we used the flowmeter DigiFlow 6710M and for the power consumption awe used the RCE PM600.
The video of the ASF NewJet DC 2000
Before we start with the review, with the technical data, we leave you to our videoreview, where not only we present the pumps and its performances, but we also explain what hydraulic head is and the differences between technical values and measured values. The video is in Italian, but you can turn the English subs on! Enjoy!
Technical characteristics of the ASF NewJet DC 2000
| European Version 100-240 V 50/60 Hz DC 24 V | |
| Maximum flow rate: | 2.150 l/h |
| Maximum power consumption: | 23 watt |
| Hydraulic head: | 2,9 meters |
| Width: | 6 cm |
| Depth: | 12 cm |
| Height: | 9,5 cm (just the body) |
| Price: | 99 euro |
The ASF NewJet DC 2000 has declared a great energy efficiency: 93,5 liters for each consumed watt and an economic efficiency of 21,7 liters per second per euro, that’s a reference value of 3.118 l*m/h.
The price is relatively low for the kind of pump, you can purchase a very solid and safe given the functioning at low voltage, dimmable on 12 steps and that has great basic features. The energy efficiency is pretty good, the economic in the average. Let’s see what we discovered in our lab and how the results are going to fits into the set of values of other pumps that we have recorded until now (on page 3).
The construction
The pump is simple: it has the classic cylinder shape. It presents itself with the black and grey livery and fuchsia details that we like very much. The impeller shell, as you can see from th pictures, screws to the body through 4 stainless steel Allen screws.
Inside the package there are two couples of rubber holders of different size. You can choose the more appropriate basing on the diameter of your own return pump. Please remember, NEVER USE the smaller rubber holder. Read this article for the reason: How to save electric power in marine aquarium: the return pipe.
The impeller is the advanced model with 6 curve blades, and that’s the difference with the previous similar pumps with similar rate. In this way the pump is way more efficient.
How to control the ASF NewJet DC 2000
The main characteristic of this pump is that its flow rate is dimmable on 12 power steps. This means that through the integrated controller we have the possibility to set the flow rate (and the head) on 12 couples of values by lowering the engine revs (remeber that they’re 24 V). Moreover, that’s a button to freeze the pump for 5 minutes. The flow rate of the pump is visualized on the 6 red LED that you find next to the buttons.
The pump is connected to the to the controller and the power through a couple of plugs.
This small power supply is given with the italian plug, capable of 48 watt, so extremely oversized for the load it has to bear.
On page two you’ll find our measurements.
