Pump works - my new review

The pump works although you will find it consumes a lot of air, this is my first time with a pump of this nature so I can't say that it is better or worse than other pumps in that area. The user manual is horrible!

Pros
  • Exactly what we ordered, works great and was packed to avoid damage.
Cons
  • Not suitable for high viscosity fluids, limiting its versatility

leaks at base where there is 2 bolts near inlet port but still worked

It leaked at inlet base first off, bolts were loose so snugged them up and slowed leak but didn't stop, was able to still use it as needed it, can't fiqure out from parts list they sent with it to what parts i need to fix leak on QBK-15, I would guess there is 4 orings, seal or gaskets i would need but no part numbers. Should have did a check over of all bolts before using it so my fault. Pump seems like good quality but if can't fix leak with new parts or parts locally it would be a throw away

Pros
  • Great looking and great working little pump
Cons
  • Cast iron body may corrode over time with exposure to certain chemicals

Worked Well Until on my review.

This pump worked well for us. We pump some fairly thick polymers and we use a portable gas powered compressor. It pumps about 10 gallons a minute of the really thick stuff (like Elmer's Glue) and about double that rate with the thinner stuff. Also, my air drier failed and damaged the pump. After much research I found that the air side rebuild kit is ARO 637434 Air Section Service Kit and available on Walmart. If for any reason this kit does not work as expected I will update this review.

Pros
  • ‎No
Cons
  • Product specifications may not meet the specific needs of certain industries or applications

Phone number for spare parts?

Have not used yet, but holy moly. even the English instructions are "broken ".kinda hard to decipher. would also be nice if there were a customer service number for extra parts.should work well though, and really fast shipping!

Pros
  • Product was great what they describe and works wonderful saves a lot of time
Cons
  • Requires an air compressor for operation, adding to overall cost
