wolfcraft Pump with Metal Casing (3000 l/h) I 2200000 I for Pumping Liquids with a Power Drill

Strong pump. Satisfied.

Used this for pumping out 500L oil from an oil tank, adding glycol to a heat pump system and sucking out engine oil from my car through the dipstick hole! Brilliant bit of kit.

Works well. I tested it moving water between 2 bowsers before opting to siphon to save my drill battery.Use a mains drill for this unless you have a cordless with substantial battery life.I opted for the metal version over plastic as it looked better made, indeed it is a solid little unit and is a quality item worthy of the price.It got 4 stars, as I’m too tight to give anything a 5.

Great product can't praise it enough. it's a small form factor and perfect for moving any amount of water.Great product

It's been very effective at draining water, pumping at a good rate with a big enough electric drill. I spray some light oil into it after each use. I connect mine to my hose-reel. I also have the smaller plastic version of the pump but find that slightly more awkward to prime.

I've been using this pump for 4 years to service a solar thermal hot water system once a year.Other reviewers (check the 1-star reviews pages 2 and 3) have used it for this same, but with less success. My experience has been generally better. I can't comment on the observations (by Others in the 1-star), that the pump contaminates the fluids. This does seem likely since it relies on the internal rubber flaps rubbing inside the housing. I propose that solar glycol-type fluid is intrinsically lubricating which maybe helped.So I managed to get good enough performance for about four uses over four years. The pump when new would provide very nearly 2.0 bar into the system. That was running on a powerful 800W drill. By use # 3 (probably after half an hour running total), it was providing 1.8 bar. By year 5, (perhaps 1 hour running total), the pump seems to have failed, and won’t circulate much liquid at all or provide any pressure. (– bear in mind that the internals have been thoroughly pickled by now for years in the solar fluid). As a result I do suspect that the inner rubbery bits have chucked their content into my pipework, but that’s hard to say because five years in the solar fluid is black and stinky and foul and needs a flush and refresh anyway.The pump will do a “negative lift”, in my case only about 20cm and I start it very gently and ensure it’s got some fluid inside from the get-go.The design looks like one reversal could instantly knacker it, and perhaps this explains some of the “useless” reviews? Make sure the drill goes the right way (forwards /clockwise) before starting out.Sadly, there seems to be little available other than this pump which is likely to do a better job for a DIY-er servicing solar thermal on a budget. I have tried lesser drill pumps in the past and they wouldn’t provide adequate pressure even from new. I might have to buy another of these, and be ready for its inevitable failure after a few uses.

Does exactly what it is supposed to do.I have several agricultural water troughs collecting rain water. I simply place my home made frame on the trough, start the drill and water my plants.

Unfortunately there was hardly any pressure for using with an irrigation system or sprinkler. There was more gravity fed power than the actual pump itself. We weren’t sure if our Dewalt battery drill was powerful enough, so decided to purchase an 800w corded drill. It still didn’t work. Thankfully Amazon are refunding the item but we would have preferred it to have worked as per the description. Not sure if we got a faulty pump, but we will never know 😳
