Description

The Everflo EF4000 is a high-volume, 12V diaphragm pump designed for users who need significant flow for larger spraying tasks. Positioned between the mid-range 3.0 GPM models and the heavy-duty 5.5 GPM units, it offers a high output of 4.0 GPM, making it suitable for both high-capacity spot spraying and small-to-medium boom applications.

Technical Specifications

Key Features

• 4-Chamber Displacement: The four-chamber design ensures a smoother flow with reduced pulsation compared to smaller pumps. This is particularly beneficial when using long hoses or spray booms, as it minimizes “hose whip” and provides a more consistent spray pattern.

• Chemical Compatibility: Built with a polypropylene pump head, Viton valves, and a Santoprene™ diaphragm. This construction is highly resistant to corrosive agricultural chemicals, including glyphosate (Roundup) and various liquid fertilizers.

• Large 1/2″ NPT Ports: The larger intake and discharge ports are essential for moving 4.0 gallons per minute without creating excessive backpressure or risking cavitation.

• Honeywell Micro Switch™: The integrated demand switch automatically manages the pump’s power based on pressure. It shuts off at 60 PSI when the flow is blocked and restarts immediately when the trigger is pulled.

• Enhanced Cooling: The motor features an internal fan to help dissipate heat during longer run times, which is common when covering larger acreage or performing high-volume transfers.

Ideal Applications

• Agricultural Boom Spraying: Capable of powering booms with 4 to 6 nozzles (depending on orifice size) for consistent field or lawn coverage.

• High-Volume Spot Spraying: Ideal for UTV-mounted tanks used for treating large fence lines, orchards, or park areas where speed and volume are required.

• Soft Washing: A popular choice for residential soft washing of siding and fences, providing enough volume to quickly apply cleaning solutions.

• Liquid Transfer: Efficiently moves water or non-flammable chemicals between storage tanks or into smaller application equipment.
