Groz 44185 Lubricant Pump, Made for DEF, Antifreeze, and Other Chemicals

Has really good suction, then blows the load where directed

Using it to pump bull def out of drum for farming pump a few times then let it siphon works great

Gets the job done

The only thing this pump will suck is your money! After 15 of furious pumping absolutely nothing (as in zero), I discovered that the top connector had been mis-threaded prior to shipping. Oh good I thought, now I will at least be able to pump out the 1/2 gallon of water from my tank...nope! After an hour of time wasting/muscle tiring, fatigue and trying to figure out what else made this pump utterly worthless, I had to go rent a real pump (for $20.00) and finish the job before my fuel delivery (the next day). The very idea that a company would be willing to sell this POS is disgusting. I will NEVER be purchasing ANYTHING from this company again.

I have purchase several and have had issues with them break. I also see that they do not completely reach the bottom of the drum, leaving several gallons of liquid to be manually poured out.

it only took about 4 pumps to fill a gal.it also stayed primed.now we will see how long it works i just got it today 8/30/2021

Works great on herbicides so far lasted a year where as metal oil pumps of similar build only last months, we have 5 of them and go through 100’s of drums a year.

This was an expensive pump. I use it to pump oil out of a drum. I pumped about half out of the drum and into buckets. Then I had to take the pump out to seal the drum back up (or the oil could start to oxidize and go bad). When I was ready to pump the remaining oil out of the pump it wouldn't work. It wouldn't create any suction. I tried everything. The pump had been stored properly. It wasn't damaged in any way after removing from drum. It was super frustrating especially since it was an expensive pump. While I loved it while it worked, I expected more than one use out of it.
