Yeah, that's correct...being only fractionally larger than the Laing D4.

How does this pump (or the Eheim 1024, MCP600, or c-systems for that matter) compare noise wise with your MD-30Z @ 50Hz? I have an MD-20Z @ 60Hz (in the USA), and I'm curious as to just how quiet the Iwakis are to other 'quiet' pumps.

Also, what would you say the life expectancy of an Iwaki MD-20Z would be? I bought an old used one and I'm not sure if I really want to put it in my new rig. :shrug:


Thanks,

Any thoughts?

longer than you

it is said a properly maintained iwaki will attend the owner's funeral

the problem is knowing its prior use
I've had a number of 40s, dry for an instant buggers the impeller and front housing

Excellent. I got the impression though the pump was run 8hours a day for several years as a "protein skimmer" (no clue what that means) it was treated well.

Um, how do you "properly maintained" a pump? Change the seals ever once in a while?

Any thought on reference to Iwaki noise vs. Csystems, the quiet Eheim model, and/or the MCP600?

Thanks

- not run dry
the 40 is a 1/4 (1/3 ?) hp motor @ 3600 RPM

How goes things on the March front Cathar?

Protein skimmers are a kind of filter, generally used in a marine aquarium.

[off topic]
Indeed.
They consist mostly of a transparent tube of different heights and diameters (depending on the capacity) and a strong waterpump that injects water from the fishtank through a venturi where it is mixed with very fine air bubbles into the tube.
The rising air bubbles act as a lift in the tube, allowing the chemical compounds of the proteins to attach to the bubbles and hitch a ride to the surface, where they are captured in a collection cup and disposed of. (under the form of a very smelly dark liquid)
