The CC6 casting unit uses a short version of the SP4 pump and fits down tightly on a standard 6 gallon bucket. The pump was designed for the small to medium size ceramic studios. It is not suitable for commercial use productions. The CC6 has an optional steel base (CC6M) with three swivel casters that makes it very easy to roll around. The motor mount combination top cover is clear so you can see inside the bucket and can easily be transferred to any 6 gallon buckets. A 3/4" x 8' pouring hose with drum faucet is included.
