Can Eheim 1264 replace MD55?

[blueheaven]

Hi guys, I need to know ASAP if a Eheim 1264 can replace a Resun MD55 for use as a return pump.

Will the flowrate be more or the same or lower?

Thanks!

i dun think so, if i am not wrong, md55 is pressure rated but ehiem is not..

u mean return pump must be pressure rated??

Nope and that is my main concern, whether the pump is pressure rated or not because of headloss consideration

I think that the higher the height for the head loss, the return would be more, all things being equal.

Though that the 1264 has a slightly higher output l/h compare to the md55,and because of the head loss, the latter would have a higher output of water.

I was once wondering why the eheim compact 5000 consumes less electricity compares to the 1264 even though it is rated 5000l/h.

after some research, i found out that the compact series has a lower height for head loss and in the end the output of water would be less.

Hope it helps.

Its best to get the info from flow chart of both pumps.

Highly doubt so... the construction of both pumps are very different... the head pressure rating on the MD55 is way much better than the Eheim....
