Putzmeister Tommy Gun® Upgrades to New Hydraulic Mixer

The A3 Tommy Gun Series of high volume fireproofing and plaster pumps by Putzmeister now feature a hydraulic-driven Hydra-Flow™ mixer by Macalite. This update replaces the previous mechanical-driven gearbox design.

The hydraulic mixer still utilizes a similar blade design to mix all materials thoroughly and quickly. However, added benefits include more mixing power and an increased capacity from 12 to 13 cubic feet. It also features the ability to run the mixer in both forward and reverse for easier clean out, more efficient discharge of materials, and a simpler way to free material blockages.

Also, a variable speed drive on the unit’s gas- and diesel-powered mobile versions now more effectively controls mixing speeds. With the diesel version, the pump and mixer run off the same Hatz diesel engine. With the gas version, the mixer runs off a separate 14-horsepower Kohler gas engine, which is 30 percent more powerful than engines found on competitive brands.

Dave Rudin, Product Line Manager - Thom-Katts® and Mortar Machines, commented, “Being hydraulic-driven, this new design eliminates many of the wear components associated with gearbox mixers.”

The new mixer is available on all Tommy Gun gas-, diesel- and electric-powered mobile and skid-mounted versions.
