Rated 1 out of 5 by This pump must be okay for something, but it did not hold up well when used to pump boiler chemicals from drums into buckets. Bought it for the pH rating, but possibly the Viton seals are not as good as the Polyethylene seals. Will try one of those next, found one for $8 more than the Viton pump. The chemicals pumped were Caustic Soda and 3-Amine Blend. The three amines typically consist of Diethylaminoethanol, Cyclohexylamine, and either Morpholine or Hydrazine. Probably the caustic soda (Sodium Hydroxide) that killed it, nothing stands up very long with that stuff, even after cleansing pump with fresh water after use. March 26, 2015
Rated 1 out of 5 by While the pump does move fluid well, the build quality is poor.We are using this in a barrel of Simple Green. Apparently, the glue holding the dip tube to the pump body is not immune to this product and came apart. Since it is just a slip fit, I am not surprised.The spout is also very loose and will fall out with normal use.Overall, not a sturdy product without modification. What a waste of time for something that should be bullet proof. September 27, 2013
