Pond one 8000 . Had mine for 2 years. Still like New
Running 2x 6' 3x 4' 6 x 2'6" & 2x 2' tanks easily

You realise a difference of 20w is only $40 per year?
And the power output is dependent on flow, the less flow the less power draw.
My lp 60 draws 40w.

I've been on a mission to try and find ways to reduce my electricity consumption in my fishroom...

Stopped using these chinese canister filters with uv light (rated at 60w each) along with other canisters... stopped using around 10 power heads (rated at 15w - 20w), changed my sump pumps to Eco pumps and saved between 35w - 70w depending on pump size and a few other things...

Overall, I've already reduced power consumption around 500-600w ($1200/yr)

So at the moment, I think every bit counts!!!

Correct me if I'm wrong...

If your LP-60 is rated @ 70L/min and 60w shouldnt it be flowing 70L/min???

Unless you restrict the flow, but isn't that bad for the pump???

Im tossing up getting one. Where is cheapest place? Is aoa?

[werdna]

You are never going to get exactly 70L/min out of it.
I have never noticed failure from a little back pressure.
Also my pump works on tanks 2ft to 1m deep, there is going to be more back pressure than normal on that depth.

i reckon hiblow, i had a 125 soniq and a 40(dunno what brand)    replaced the 2 with a refurbished hiblow 80 and its got more outlets than the other 2 had and still heaps more air, and they last for ever

The quoted output of pumps is for free air (unrestricted flow), and incidentally is the greatest power consumption situation. All pumps, by definition run under some "back pressure"/restriction, and naturally this reduces flow proportionally to the amount of restriction. Any restricted output also naturally results in a decrease of cooling air-flow within the pump.

 

i have several  Sakagurawa Hi-Blo pumps of the old SPP types, and replacement parts for these are virtually unobtainable. I find that the life of diaphragms can be maximised by cooling the pump exterior by the simple process of blowing an air stream from a small personal fan over the pump. I place the fan as close as possible to the pump, and I consider this at least doubles the diaphragm life. Of course, the fan consumes some electricity (circa 12 watts), but I consider this acceptable inasmuch as the service life is so considerably extended.
