MixerPump is a combined volumetric concrete mixer and concrete pump that can be driven to the jobsite. It pumps pea-gravel mixes, ¾-in. blend mixes, 1-in. big rock mixes, and low-slump shotcrete mixes. A tapered underside allows for pipe and hose storage. The pump can be disconnected from the mixer when not in use and quickly reattached, and attaches to mobile or stationery volumetric mixers. Reed Concrete Pumps. 888-779-7333. www.reedpumps.com
