Everflo 12V On-Demand Diaphragm Sprayer Pump — 3.0 GPM, 60 PSI, Quick-Attach Ports

The Everflo 12V On-Demand Diaphragm Sprayer Pump delivers up to 3.0 GPM and 60 PSI with quick-attach ports, corrosion-resistant materials, and an automatic power switch for efficient, reliable fluid transfer.

This compact 12V diaphragm pump is engineered for mobile and fixed water-handling tasks where durability, easy installation, and energy efficiency matter. Built with a Honeywell Micro Switch™, Viton valves, and a Santoprene™ diaphragm housed in a fiberglass-reinforced polypropylene manifold, it resists chemical and environmental wear while maintaining smooth priming and long motor life. CE approved and supplied with two quick-connect fittings, it’s a ready-to-mount solution for agricultural spray rigs, de-icing systems, irrigation lines, and light pressure-washing setups.

How does this Everflo pump save battery power during intermittent use?

The pump features an automatic on-demand pressure switch that stops the motor when flow isn’t required and slowly cycles it during minor pressure changes to minimize electrical draw. That reduces deep cycling of the battery and lessens wear on the motor and switch, extending component life and conserving power for mobile installations.

• Automatic pressure switch for power savings
• Slow cycling reduces motor and switch stress
• Efficient priming lowers run time

What materials and components make it suitable for harsh fluids?

Key wetted parts are selected for chemical and abrasion resistance: Viton check valves and a Santoprene™ diaphragm resist many agricultural chemicals and salt brine, while the fiberglass-reinforced polypropylene manifold handles impact and corrosion. Electrical reliability is bolstered by a Honeywell Micro Switch™, designed for consistent on-demand operation.

• Viton valves for chemical resistance
• Santoprene diaphragm for long flex life
• Fiberglass-reinforced polypropylene manifold for strength

How easy is installation and hookup for field or vehicle use?

The pump uses a standard mounting pattern for straightforward attachment to panels or frames and includes QC-to-1/2" hose barb and QC-to-1/2" MNPT fittings for fast plumbing connections. Quick-attach ports let you swap hoses or service the unit quickly without special tools, cutting downtime during seasonal or mobile operations.

• Standard mounting pattern for quick installation
• Includes QC x 1/2" hose barb and QC x 1/2" MNPT fittings
• Quick-attach ports speed hose changes and maintenance

What applications suit the Everflo 12V On-Demand diaphragm pump?

This pump is intended for moderate flow pressure tasks where portability and chemical compatibility are important. Typical uses include spot or broadcast agricultural spraying, salt-brine de-icing, small mobile pressure-wash systems, water transfer and irrigation feeds, misting lines, and compact fire-suppression or emergency water delivery setups.

• Agricultural sprayers and crop applications
• De-icing and salt brine distribution
• Mobile pressure washing and water transfer

Who is this for? Installers, farmers, landscape contractors, and fleet technicians who need a compact, dependable 12V pump with chemical-resistant internals and quick-connect plumbing will find this Everflo model especially useful. It’s designed for users who require energy-efficient on-demand performance, straightforward mounting, and materials that resist corrosion and wear. Backed by a two-year warranty, it’s suited to seasonal professionals and mobile systems where uptime and ease of service are priorities.
