Contractors can use the D6528 Mixer/Pump to pump up to 1/2-inch aggregate concrete mixes, eliminating the need for additional concrete pumping equipment

The D6528 Mixer/Pump’s hydraulic mixer blends up to 9 cubic feet of material in just 45 seconds as the machine dumps material into the unit’s 12-cubic-foot hopper with hydraulic agitation. 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.

The D6528 Mixer/Pump’s squeeze pump features a 3-inch rubber pumping tube mounted inside the unit’s circular housing, where the roller section rotates and effectively pumps material through the tube. If a blockage does occur, operators can simply run the pump in reverse to relieve pressure and reduce the risk of injury that can occur if they were to open the line under pressure.

The D6528 comes equipped with a 29-horsepower, water-cooled diesel engine or an optional 40-horsepower Kohler gasoline engine. Blastcrete designed the unit with the engine placed away from the mixer and receiving hopper to prevent thermal transfer that can cause material to set prematurely.
