Type: Return Pump
Brand: Jebao
Model: DCT-8000
Claimed Watts: 75W
Actual Watts: 71.5W
Comments:

On full power (10), the Jebao DCT-8000 pump draws roughly the claimed power consumption.

Below at are the readings on the various power settings below 10.

  • 20.3w
  • 24.3w
  • 29w
  • 34w
  • 39.4w
  • 45w
  • 51.6w
  • 57.5w
  • 64.5w
  • 71.5w

@i-CONICA . Does the wattage change with the load at a given speed? ie if you had more flow resistance through greater head height maybe you would see a slight increase in Amps and therefore Watts. I suppose this could be tested by partially closing the return valve....

Good point, I'll experiment. I've got no resistance at the minute other than the head-weight through my 32mm plumbing, and various elbows.

I'll do the same tests if the ball valve on the return line is closed somewhat. Although with my head-height, and various elbows, even though it's 32mm plumbing, I'm getting pretty much spot on (slightly less) than the specifications suggest, so maybe the claimed figures are based on a typical plumbing set-up, and if so, then my sub-readings of lower settings should fall roughly into line as my base-line max power figure is on point.

So with the ball valve closed to about half way, the readings all actually reduce by about 15%. So straining this pump doesn't increase it's consumption, it reduces it. So maybe it's total revolutions for this type of pump which govern it's consumption, not load.

They do state High performance motor with innovation electronics, and energy saving up to 50% than before.
