TeraPump 20012 Barrel Pump (TRRP90P Plastic Rotary Drum for water based solutions and all petroleum products), 1 Pack

No instructions were included, but the pump assembled easily and intuitively. Construction is pretty solid. The inlet and outlet ports are 3/4 BSP, so adapting a different tube would be easy if needed. The pumps works well and I'll probably buy a few more. Thanks.

I have used this now for several weeks in a 12% Sodium Hypochlorite (Chlorine Bleach) drum and it work great. About 10 handle turns gets you a gallon. Good product. I have tried other ones and if there is any metal whatsoever or cheap rubber parts the bleach corrodes and/or disintegrates it in days. Not this one. Highly recommend. I do rinse it every time after use by running fresh water through it but honestly don't think that's even necessary.

I purchased this pump primarily for watering some recently planted fruit trees using a 55 gallon drum mounted on the back of my tractor. I selected this pump mainly because being plastic, it should not corrode like cast iron or other metal pumps. I have been using it about once every week for two months now. It works pretty well for the most part, but has a few shortcomings.First, the good points:1. It is inexpensive.2. Easy assembly.3. Not difficult to use, but I wouldn't advise be too rough with it.Now the not so good:1. The threaded connections are fine threads, which are very shallow on the plastic suction tube and do not have much holding power. Why is this an issue? Over tighten them once when threading into the bottom of the pump housing (even if using only your bare hands and no tools) and you'll find out just how easily they strip. Once you strip the threads, the pump will constantly suck air through the threaded connections and will easily not draw fluids up through the tube. This leads to another immediate problem- you cannot simply glue the stripped threads into the pump housing or then you cannot remove the collar that fits into the barrel bung and holds the pump assembly in place. IMO, this is a design flaw and was not very well thought out. The good news if this happens to you- you can still take it back apart and swap the top and middle sections of the suction tube around if the one at the top is stripped out where it threads into the pump housing- and use pipe sealant on the stripped threads so it won't draw in air.2. The collar that threads into the barrel bung was difficult to start into the threaded connection on the barrel and is made of plastic with a metal clip and thumb screw that is tightened against the suction tube to hold the pump assembly in place. This screw is inadequate to prevent the whole assembly from rotating relative to the barrel when using the handle to pump. Another poor design that could be easily fixed by putting a a small flat section on the suction tube for the thumb screw and clip to press against and more firmly hold it from moving while you are trying to pump with it.3. The 2-piece discharge tube has a swivel union that dribbles a little where the two pieces mate together- but being plastic, I had learned my lesson on over tightening. Another minor complaint- there are no pipe threads to connect a hose barb fitting into the outside end of the discharge tube. I ended up using a pipe tap to cut some threads so I could attach a standard plastic 3/4" garden hose barb. Otherwise you would have to attach a very large diameter hose (maybe 1 1/4"?) OVER the outside of the discharge tube and use hose clamps to attach it.Overall, the pumps works pretty well despite these issues and for the cost, I can't really complain too much. It pumps a good volume with the 3/4" garden hose and I can empty the entire 55 gallon barrel in about 12-15 minutes without working too hard rotating the pump. Sometimes it can be a little difficult to get the pump to prime if is has no residual water left in the hose. A more robust suction tube and stronger threads would fix most of these problems. Had it not been for the above issues, I would have given it a much higher rating.

Great product, strong material. Will purchase again

We use this pump in one of our water barrels...we needed about another six inches of tubing to allow the pump handle to clear the sides of the barrel when we pumped the water...the company was absolutely no help in assisting us to find a length of tubing we could use to extend the height of the pump head. We finally solved the problem by using a compression fitting to add a length of PVC tubing. The pump itself is great.
