Designed and created from the field by installers who needed a lightweight, one person operational pump. Empty, this pump weighs less than 35 pounds and can be carried as a backpack (hence the name). A cart is available also which accommodates the SCOUT and a small compressor. Compressed air is supplied through a series of regulators and meters so the operator can control the flow easily. Also includes two shut off valves per side (A & B) for safety, and camlock connectors for easy cleaning and storage.
