Default eheim 1264 vs compact 5000

Guys need advice here.
Both pumps are from eheim.
1264- old model
4500lph
100w

5000 - new model
2500 to 5000lph
86w

As it can be seen that lots of people still prefer 1264.
1264 bulky
5000 smaller

Please advice.

The outlet of the 2 pumps are different. 1 is a nozzle the other comes with screwthread.

Head loss in lay man terms... the longer the distance water travels the lesser the flow rate?
Hope i got it right and didn confuse u. Haha

The stated flowrate is measured at the outlet, thus is at 0 headloss

The real loss is more on the vertical distance the water has to travel rather than the horizontal distance. Number of elbow joints also contribute to more losses in flowrate.

Hmax I think refers to the maximum effective pumping height of the the pump.

Do correct me if I'm wrong. That's my understanding. Most pump packagings do come with a flowrate chart that gives flowrate vs pumping height. Just need to take a measurement of your pumping height and compare to whichever pump best suits your tank.
