SprayMaster® by Airplaco

Cincinnati, Ohio – Airplaco Equipment Company, a US manufacturer of equipment for the shotcrete, gunite, masonry, grouting and mining industries, announces the latest design of its SprayMaster® rotor-stator pump. Model SM-78G is engineered and built for spray applications, such as stucco, eifs, low-volume plaster, fireproofing and finish materials. The SM-78G offers a continuous flow of materials, making it suitable for underlayment projects as well.

“The pump fills out the product line”, says Todd Ferguson, Marketing Manager. “We listened to what customers were asking for and our engineers were able to design a solution. Best of all, it is made in America by an American owned company.”

The SprayMaster’s rotor-stator design is also referred to as “worm gear” or “screw type pump” in the industry. This design allows for a continuous flow of material. The SM-78G can output up to 10 gallons per minute of materials, which are typically pre-bagged fireproofing, stuccos and other spray finish materials. The SprayMaster has an exclusive variable speed control, allowing contractors to adjust the production rate without sacrificing power. The pump has a 14 horse-power gasoline engine and includes an onboard air compressor to provide air to a spray nozzle.  The narrow width of the machine allows it to pass through a standard 32 inch doorway for access to interior work spaces.
