When you are going to the top, choose the pumps that have already been there – the SP 8800.
These are the high pressure workhorse pumps that have topped out more high rise buildings than any others. The technology of our twin-cylinder, all-hydraulic open loop system concrete pump has been refined for decades along with the proven Rock Valve™ that is so important to reliability and cost of operation.
The Rock Valve’s design creates positive pressure within the valve which is ideal for high pressure pumping applications. As pressure from the concrete acts on the pressure spring, a tighter seal is created between the carbide cutting ring and the wear plate.
