Look at the pump manufacturer’s spec sheets for the machine’s output rate (usually given in cubic yards per hour) and maximum horizontal and vertical pumping distances.

A high-capacity pump usually isn’t necessary for placing thin cement-based overlays. And to take advantage of a pump with super-fast delivery rates, you must have enough workers on hand during the placement to keep up with the pace. This is especially critical on decorative stamped concrete jobs because you have a limited window of opportunity for finishing and stamping after the concrete hits the ground. For decorative work, consider going with a pump equipped with variable volume control, which lets you adjust the pump output to suit the tempo of the job. This will permit you to slow down concrete delivery if the finishing or stamping crew falls behind.
