The heartbeat of any productive portable spray foam machine is the pump and the very best pump that you can use is an air pneumatic plural pump. That is the good news. The bad news? It is difficult to find a portable spray foam machine that uses this type of pump.
Hopefully that will be changing soon, but if you can’t find a machine that has one, you may think twice about buying that equipment. So why is this type of pump so effective? The answer to that question lies in it’s simplicity.
The air pneumatic plural pump has been around for a long time, but it is used mostly for bigger spray foam machines. Here are just a few reasons why it is perfect for the smaller more portable spray foam machines.
· No electrical power needed as air drives the pump
· The 1:1 mixing ratio is very precise
· There are a minimal amount of parts
· The pump can easily be repaired
· The ability to clean the system is improved
