This machine has the ability to use two different sized buckets; a 5-gallon and a 55-gallon drum to pump out the sealant used for glass assembly. This machine will pump the sealant component from one bucket and the hardener component from another bucket in the most consistent and accurate way. This machine is equipped with a static reciprocating mixer to ensure that the right components mix properly. This machine is used in any sized production shop to increase efficiency and achieve higher productivity. This machine is built on a rigid steel frame for better stability.
