Restricting flow on powerhead without....

[stealth_elongatus]

burning it up. Has any one done so?

 

[sabotage]

put a pvc 90 degree or something to deafen the pressure, more of like a muzzle.....

i'm looking to feed the outlet of the powerhead into about 15 - 20 feet of line.
was wondering if the pressure would burn up the motor?

think of it as almost using it as a wet/dry pump.

True powerhead don't lift water they just 'push' it.

As long as it has sufficient water flow to cool it, the magnetic drive pump should be ok.

Before you build something around this pump, definitely build a mock-up and try it for flow.

thanks dr. joe -

i should expect a slight gain in water temp then ?

 

[Dr Joe]

If the pumps big enough and the tanks small enough .

usually if you restrict the outlet the pumps will be fine...as long as they are moving some water.

or you could ziptie/rubberband a sponge or two over the outlet to diffuse the flow
