drill pump

[killian]

I picked up a drill pump a while ago to recirc Ice water for chilling. I had some problems when I hooked it up. I think the hose was too long, the water was recirculating but it just wasnt flowing very fast and my temp wasnt dropping. So next time I think I'm going to cut my hose down so it is just long enough to reach near the bottom of the ice cooler. Any thoughts?

What kind of probelms? How long was your hose? What were you expecting?

I think the GPM of those drill mounts is much less than your standard garden hose.

well I ran it for about 15 min and the temp didnt drop at all (from 69 deg). The hose to the chiller was about 6 feet long or so ( I didnt think about the hose length causing a slower flow rate). I used about 14 lbs of Ice. I was hoping to get down to lager pitching temp.

We used to have those on the farm, 6' isnt long... Id suspect there are other issues, not the hose length.

did you put a few drops of mineral oil in the pump? it helps great a good seal and keeps the rubber parts flexible

6' shouldn't be a problem but for priming the pump (between the pump itself and the cooler of water) the shorter the better. These pumps work decently but they are usually cheaply made, so it could just be a bad pump. That being said I've had no problems going a few feet into the pump then spliting the flow into two 25' lengths of 3/8 tubing. The flow is more than fast enough for cooling. In cooling the temp difference in the water isn't nearly as vital as a good flow speed, too fast or slow and you won't get efficient heat transfer.

this was the first time I used the pump. The speed of the water through the chiller was way to slow. From the pump to the chiller it was probably 3 ft.

I would guess that there just wasn't enough flow to do much good. Did you circulate (stir) your wort as well?

 

[killian]

yes, the out flow was pretty slow

Make sure that you have the suction and discharge of the pump correct for your application, in addition to the rotational direction of the drill. I've used them a bunch for pumping SAE 46 oil at work, and they work pretty good (solid stream) if you have everything correct. If it's not set up right, they don't pump much at all.

Is this a new pump? If not it may have some cob webs or other obstruction inside.
