Parts and Solo Backpack Sprayers
The Solo 474 Backpack Sprayer is a durable and versatile sprayer equipped with a diaphragm pump, ideal for handling abrasive materials like wettable powders. Designed for professional and heavy-duty use, it delivers a maximum pressure of 60 psi, ensuring consistent and precise spray coverage. Unlike piston pump models, the Solo 474 is built to resist abrasive media, making it the perfect choice for applications involving suspensions and viscous materials. This sprayer is suitable for a range of agricultural and commercial tasks, offering reliable performance and excellent chemical resistance.
