The attachment features Blastcrete's 3in hydraulic squeeze pump, making it ideal for ICF, block fill, form and pour, driveways, basements and shotcrete applications. The receiving hopper includes a hydraulic agitator that keeps the mix well-blended, ensuring aggregate and sand stay evenly suspended throughout the mix. Not only does this result in high-strength concrete, but it also keeps the aggregate and sand from settling to the bottom of the hopper and clogging near the suction area.

The RD6536 offers variable speeds of 0-25 cubic yards per hour. Contractors can pump materials 250ft horizontally and as high as 50ft with the use of a rubber delivery line.

Operators can run the RD6536 in both forward and reverse to relieve pressure build-up clogs and eliminate potential damage to the pump. The pump also features hydraulically powered controls that operate both agitator and pump speed. The unit's oil requirement is 18gpm at 3,000psi.

The skid-steer pump weighs 2,700lb and features a 48in wide frame (55in with the receiving hopper), narrow enough to fit between the wheel wells of most standard work trucks. The RD6536's forklift pockets allow quick and easy loading and unloading from the transport vehicle.
