PRIDDY "Continuous Flow" Concrete Pumps eliminate surge by utilizing a patented 3-position “YS-Tube” & Trapezoid cutting ring. Pressure and flow of the concrete material is never lost during the valve shift. This also allows the pumping pistons to both discharge simultaneously at the beginning and ending of their strokes!
PRIDDY is committed to developing this same technology to be integrated into all types of applications in our industry! Imagine a surge-free Boom Pump regardless of the placing boom configuration, pumping volume and/or concrete slump!
