Fimco 12V Diaphragm Sprayer Pump 60 PSI 2.1 GPM with Internal Cooling Fan and Upgraded Pressure Switch

The Fimco High Flo 12-volt diaphragm sprayer pump delivers up to 60 PSI and 2.1 GPM with an internal cooling fan and upgraded pressure switch for longer, cooler operation.

This compact 12V diaphragm pump is engineered for demanding agricultural and landscaping spray tasks where reliability and cooler running matter. It combines a high-flow diaphragm design with a built-in fan and beefed-up motor windings to reduce heat buildup during extended use. The pump draws about 8 amps under normal conditions and is designed to resist thermal stress through improved components and an upgraded pressure switch for more durable cycling.

How does the built-in fan improve pump performance?

The internal fan actively circulates air around the motor and housing, lowering operating temperature and reducing heat soak. Cooler operation helps maintain consistent pressure and extends motor life when you run the sprayer for long periods.

• Reduces operating temperature by up to 50% compared with uncooled models
• Helps prevent thermal shutdowns and premature wear
• Supports steady flow for extended spraying sessions

What are the key specifications I should know?

This Fimco pump combines practical flow and pressure for common spraying tasks. It runs on a 12-volt electrical system, delivers a maximum of 60 PSI, and produces approximately 2.1 gallons per minute at optimal conditions. The electrical draw sits near 8 amps, making it compatible with standard 12V battery setups on trucks, ATVs, and tractors.

• Voltage: 12 VDC for vehicle or battery operation
• Maximum pressure: 60 PSI for higher-pressure applications
• Flow rate: ~2.1 GPM for efficient coverage
• Current draw: ~8 amps for typical power planning

How does the upgraded pressure switch and motor winding improve durability?

Fimco updated the pressure switch to withstand more cycles and resist early failure, and the motor windings are thicker to dissipate heat better. These hardware improvements reduce stress on electrical components and help the pump last through more frequent on-off cycles and long runs.

• Upgraded pressure switch for longer service life and reliable cut-in/cut-out
• Enhanced motor windings improve heat dissipation and reduce thermal fatigue
• Design choices focused on longevity in field conditions and prolonged use

What fluids can and can’t I use with this pump?

The pump is designed for water-based sprays and many agricultural and landscape chemicals compatible with diaphragm materials. It is not intended for flammable or combustible liquids; avoid solvents, fuels, and other volatile fluids to prevent damage and safety risks.

• Suitable: water, water-based herbicides, pesticides, fertilizers as permitted by chemical labels
• Not suitable: flammable or combustible fluids and aggressive solvents
• Always follow the chemical manufacturer’s compatibility and safety instructions

Who is this for? The Fimco High Flo 12V diaphragm sprayer pump is aimed at farmers, landscape contractors, and property owners who need a dependable, cooler-running pump for towing sprayers, ATV-mounted rigs, or truck-bed systems. If you want a 12-volt pump with a strong balance of pressure and flow plus design updates that reduce heat and extend component life, this pump is a practical, service-oriented choice. It is especially useful when you require continuous spraying without frequent thermal interruptions, and when compatibility with standard 12V power sources and common agricultural chemicals is a priority.
