This pump, originally from PanWorld, is a new pump from the series PI able to use 12 V. This pump is design for maximum pumping power and guarantees maximum performance. This pump is a "high pressure" pump in comparison to traditional pumps in watercooling. (No kinding!!) It is able to attain more than 9 meters of H2O at pressure max, about 1 bar or 14.7 psi for US units!

The diameter of the pump head is impressive and the design was made to increase pressure. The diameter of outlet is 4 mm of internal passage for 8 mm external. The inlet on the other hand is 18 mm of external diameter with a passage of 14 mm. It is necessity for large tubing connecting directly to a reservoir. This pump is especially strongly and ...French jargon... good for a restrictive loop where more pressure is needed. As the AQX50Z, one can position the head in 6 different directions to adjust it according to its needs:

The design is the same as the AQX50Z, but with more power in mind. One can find the 2 distinct rotors and a magnetic entraînement with 6 curved channels. The electronics are internal but in a exterior compartment with connections to the sensors and electrical equipment around the srtator. 6 MOSFETs are under the PCB directly and are linked up to the metal shell to use cool properly.

The rotor is a closed type with 6 curved canals. The diameter of the rotor, that turns to ß3200 tr/min, is of 60 mm in order to obtain a speeds need to have a more pressure (conversion speed pressure). There is only 2 manners to obtain this pressure with a centrifugal pump. 1) increases the diameter of the rotor 2) increase RPMs. Increasing rpms creates more noise therefore is not viable in comparison with the first solution. The bearings are ceramic materials and the secondary axis is 6 mm in diameter.

As seen, the rotor has large canals than its smaller sibling. They remain almost identical, but the exit diameter is a bigger ratio allowing for higher flow rate. One could modify the 150Z while cutting the 8mm outlet, then added a new outlet for higher flowrate... One sees well that the rotor of the 150Z is clearly more imposing than the one of the 50Z:

Having a big rotor means having more inertia. The pump needs a long start up accelerates gently for about 15 seconds to attain nominal speed.
