The Nupulse Style bucket assemblies are the type we use on our Mini-Milker milking machines. The Nupulse style are a unique bucket assembly because the claw and the pulsator are all one piece. This makes it very simple and easy to use. The Nupulse style bucket assemblies come with everything that you need to milk, except the vacuum pump. The bucket assembly includes, milk bucket, lid and gasket, Nupulse claw, shells, inflations, and all other necessary rubber goods
