Compact and dependable, our machines are capable of pumping traditional plaster and stucco at high speeds and long distances. Their lightweight portability also makes them particularly effective in applying material to tight, hard-to-reach areas. When you need plaster or stucco spraying done quickly and reliably, nothing does the job as well as our products. There are pumps … and then there are Hy-Flex pumps. They’re in a class of their own.
