No other sequencing valve combines lowest cost per yard maintenance costs and ease of rebuilding as the Rock Valve™.
"Have the pump out and running and I am really impressed. Even all the sceptics now think it was a good idea. Did 50 yards in a 16’ ceiling and could not be happier. Only thing I would change is a toolbox above the battery box so you don’t have to climb up on the truck so much."
- Andy H. Stachler, Stachler Concrete , St. Henry, OH
"High utilization of the equipment is the name of the game for concrete pumpers which is why I own three 17-meter boom pumps and the S 20. We have a lot of customers who specifically request our small boom pumps, so when I was introduced to the S 20 with the 4-section boom I instantly recognized it as a tool we could use.”
- Jim Toothaker, owner, Independent Concrete Pumping, Wakefield, MA
