The D6528 Mixer/Pump from Blastcrete Equipment Co. gives gypsum flooring contractors a versatile and easy-to-use mixer/pump with high capacity and low maintenance, according to the company.

Contractors can use the D6528 Mixer/Pump to install gypsum underlayments for sound and fire proofing floors, as well as up to ½-inch aggregate concrete mixes for breezeways and patios. 

The mixer/pump's hydraulic mixer blends up to 9 cubic-feet of material in just 45 seconds and keeps it in suspension as the machine dumps material into the unit’s 12-cubic-foot hopper with hydraulic agitation, according to the company. Operators can use a skid steer loader and Blastcrete’s optional calibrated bucket to load as much as 7.6 cubic-feet of material into the mixer at a time.

“We have been very impressed with what we can do with the unit,” said Dewayne Olsen, owner of Western Slope Gypsum in Rifle, Colo. “We can pump gypsum up to five stories high and as far as 400 feet horizontally.”

The mixer/pump features high-quality, heavy-duty, tubular steel frames that reduce noise, vibrations and the risk of cracks that can occur with channel frames. The mixer/pump comes equipped with a 29-horsepower, water-cooled diesel engine or an optional 40-horsepower Kohler gasoline engine.
