Tunze 1073.02/04 Recirculation Pump Silence

[LSUtiger]

Roger, is there a pump curve/performance table in gpm/ft for the 1073.02 pump? The manual on Tunze's site doesn't appear to be in gpm, and it is very blurry.

I'm curious what flow I could achieve pumping up ~50". I did find a clearer curve, and it looks like the flow would be about 200gpm for the 1073.02 pump and 462gpm for the 1073.04 pump. Am I in the ballpark?

Can these pumps be turned down? I'm looking for around 300gpm through the pump/sump.

Also, can you provide the footprint dimensions for both pumps? I can't make that out.

Thanks,
Mark

The pump measures 4.5 * 3 * 3.5 without the hose nipple or suction cup feet attached. It does have a mechanical flow adjustment knob on the intake. The flow in the chart is given in cubic meters/ meters of head, the clearest chart is on page 6 of the manual, if you download the manual and view it in Adobe acrobat it should be pretty clear. Your numbers are very close. I calculate that 50" is roughly 1.25 m at 1.5 meters a 1073.04 does about 390gph.

Thanks for the reply. I could probably tolerate the 390gph, but I'm glad to know I can adjust the flow if needed.

Thanks,
Mark
