Description
Upgrade your sprayer system with the Fimco 4.5 GPM 12V High-Flo High-Performance Pump—engineered for demanding spot and broadcast spraying tasks. This automatic-demand diaphragm pump delivers reliable performance with 4.5 gallons per minute of flow and a maximum pressure of 60 PSI, making it ideal for use in agricultural, lawn care, and pest control applications.
With quick-connect ports, chemically resistant internals, and a self-priming design, this pump is built for durability and ease of use. The integrated automatic demand switch conserves power by shutting the pump off when maximum pressure is reached, while internally fan-cooled motor components ensure consistent performance during extended use.
