Blastcrete Equipment LLC, a long-time manufacturer of shotcrete and gunite mixers and pumps, has introduced the RS180 mixer pump with variable speeds from 0-18 cubic yards per hour and long-distance and high-volume pumping capabilities. The RS180 is a user-friendly, economical option for gypsum flooring underlayment, grouting, cellular concrete and some wet shotcrete applications. It offers contractors smoother material delivery for specialty applications, ease-of-use for operation and maintenance, and industry-leading durability for optimum efficiency in a variety of applications.

To eliminate material surges and allow for higher pumping volumes, Blastcrete's RS180 incorporates an adjustable 2L8 rotor-stator pump. The adjustable rotor-stator, or progressive cavity, design allows contractors to tailor material flow to the job at hand.

By tightening the unit, operators can increase line pressure for longer vertical or horizontal pumping distances. For shorter distances, the unit can be loosened. This flexibility limits wear compared to other rotor-stator pumps and results in industry-leading longevity and durability.

In addition to the 2L8 rotor-stator, the RS180 features a 12-cu ft hydraulic spiral mixer, driven with a planetary gearbox, offering variable speed from 0-60 rpm for application- and site-specific adjustments. Mixing a full load in less than two minutes, the robust mixer minimises downtime and ensures a continuous flow of material. A 15-cu-ft receiving hopper, easily charged with 1,000-pound bulk bags or 11.6-cu ft skid steer bucket, further increases jobsite efficiency.
