Overview

The FIMCO High Flo 12V Demand Diaphragm Pump delivers dependable, high-flow performance in a compact 12-volt package. Suitable for both spot spraying and broadcast coverage, it moves up to 4.5 gallons per minute at up to 60 psi.

Smart design for tough jobs

Inside, the pump features an internally fan-cooled motor that sustains steady performance under heavy load, along with chemically resistant elastomers that maintain flow and reduce wear. The self-priming design ensures reliable startup, and running dry won’t damage the unit, giving you confidence during busy days in the field.

Durability and compatibility

Designed to endure daily spraying, this pump includes built-in check valves to maintain pressure and prevent backflow, plus chemical resistant elastomers that stand up to common spray formulations. Quick attach port fittings simplify installation, and an inline fuse protects the circuit from surges. The fan-cooled motor and ball bearing drive contribute to long-term reliability, backed by a 2-year warranty. It is compatible with a variety of common spray formulations, including glyphosate-based products.
