Blastcrete Equipment LLC’s RD6536 skid-steer pump attachment is compatible with any skid-steer, and provides a fast, efficient solution for pumping grout materials, 3/8-inch shotcrete and 3/4-inch structural concrete mixes in a variety of concrete and shotcrete applications. The attachment features Blastcrete’s 3-inch hydraulic squeeze pump, making it ideal for ICF, block fill, form and pour, driveways, basements and shotcrete applications.

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

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, it keeps the aggregate and sand from settling to the bottom of the hopper and clogging near the suction area.

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 18 gpm at 3,000 psi.

The skid-steer pump weighs 2,700 pounds and features a 48-inch wide frame (55 inches 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.

Blastcrete designed the RD6536 for a long service life and fast and simple maintenance by using steel construction that prevents concrete from coming in contact with the pump’s moving parts. Unlike other types of concrete pumps, cleanup on the RD6536 squeeze pump is fast and hassle-free. Using just water and a sponge ball, the pump can be cleaned in about 5 minutes. Further, the primary wear part, the rubber pumping tube, can be easily replaced on the jobsite in about 20 minutes.
