Our comment
After the great feedbacks of our friends we had very high expectations on this pump, and we weren’t disappointed! The pump keeps perfectly its promises and this rarely happens, especially for what regards the rate, that almost never matches the declared data. But this isn’t the case!
These conclusions will be really full of material since we’ll do a comparison with similar pumps we have tested before!
The comparison with other pumps
The comparison with the other pumps we’ve tested is very interesting. In particular, we’re comparing the data of Eheim, Hydor, Tunze, Sicce, Corallinea, Waveline and Ecotech Marine, all here below in the chart. These pumps have also their dedicated review. We ordered the chart basing on the reference value of the pump, that is the product of the flow rate times the head divided by 2. In this way we obtain the subtended area. We believe this is the only way to compare homologous pumps. If the reference value differs too much we think they can’t be compared.
| Pomp | Head | Rate | Reference value | Power consumption | Price | Efficiency | Economic efficiency | Annual cost |

You can see from the chart that economically speaking, that is the rate per euro, the Newa Jet 1700 is the most convenient with its 38 l/h per euro. For what regards the technical efficiency it’s in line with the average. So, if the couple of values you research match with this pump, as you can verify in our calculator, you’ve found what suits you.
The relationship with the declared data
Now let’s see the closeness to the data declared by the manufacturer.
Head
| Pump | Head | Measure | Gap |
| Newa Jet 1700 | 210 cm | 200 cm | – 5 % |
The measure of the head has a very insignificant gap. The Newa keeps its promise.
Rate
| Pump | Rate | Lab measure | Gap |
| Newa Jet 1700 | 1.700 l/h | 1.683 l/h | – 3,5 % |
The gap between measured and declared rate is close to 3,5%, but we were very close to what was declared. Chapeau! Also because often the gap is up to 40%.
Power consumption
| Pump | Power consumption | Lab measure | Gap |
| Newa Jet 1700 | 33 w | 31,3 w | – 5 % |
The power consumption is inferior of the 5%. Even here another value absolutely in line with what declared.
Closeness to the declared data
Finally we can assign a value of the correspondance with the data declared by the manufacturer for what concerns rate, head and consumption.
| Pump | Head | Rate | Power consumption | Final Value |
| Newa Jet 1700 | 95 % | 96,5 % | 95 % | 95,5 % |

Conclusions
The reference value of the Newa Jet 1700 is 1.638 l*m/h, where the declared reference value is 1.785. The gap is very little, about 8%. Remember that the reference value is the area subtended by the values of head and rate. The calculation is (head x rate)/2.
The loss 13% actually represents a very great value given the fact that the other competitors do worse.
In order to use a pump in our aquarium we always have to consider what it actually express, and not what it should. But in this case the values are practically identical. An incredible feature!
PROS
Great performances and coincident with the declared data
Very well built
Silent
Very convenient
CONS
Nothing to report!
