Everflo 12V Diaphragm Water Pump EF2200-QA-BOX — 2.2 GPM, Quick-Attach Ports, Corrosion-Resistant

The Everflo EF2200-QA-BOX is a 12V on-demand diaphragm pump delivering up to 2.2 GPM and 70 PSI with quick-attach ports for fast, tool-free connections.

This compact, corrosion-resistant pump is engineered for mobile and stationary water-handling tasks where reliability, battery efficiency, and easy installation matter. It combines durable materials like Viton valves and a Santoprene diaphragm with a fiberglass-reinforced polypropylene manifold and a Honeywell micro switch to give consistent performance across spraying, transfer, and washdown jobs.

What are the pump’s core performance features?

The EF2200-QA-BOX runs on 12 volts and supplies a steady flow up to 2.2 gallons per minute while reaching pressures up to 70 PSI. It’s self-priming to about ten feet and uses a pressure switch that cycles slowly to reduce wear on the motor and switch.

• Maximum flow: 2.2 GPM and max pressure: 70 PSI
• Self-priming capability up to 10 feet
• Slow-cycling pressure switch to extend component life
• Automatic power shutoff when no flow is required, saving battery energy

How is it built to resist corrosion and wear?

Key wet-end components are selected for chemical and wear resistance: Viton valves and a Santoprene diaphragm tolerate many water-based fluids and reduce maintenance. The manifold is fiberglass-reinforced polypropylene to withstand harsh environments without adding heavy metal parts.

• Viton valve materials for chemical resistance
• Santoprene diaphragm for flexibility and longevity
• Fiberglass-reinforced polypropylene manifold for rigidity and corrosion resistance
• Silky-smooth valve geometry for faster priming and reduced pulsation

Which connections and installation options are included?

The pump ships with two quick-attach fittings to connect common hose and plumbing sizes quickly. It follows a standard mounting pattern so you can replace or install it into most sprayer tanks and mobile systems with minimal modification.

• Included fittings: one quick-connect to 3/8" hose barb and one quick-connect to 1/2" MNPT
• Quick-attach ports for fast tool-free hookups
• Standard mounting footprint for simple replacement or retrofit
• Compact footprint suitable for tight engine bays or tank compartments

What applications is this pump suited for?

The EF2200-QA-BOX is versatile for many water-focused tasks. Typical uses include agricultural spraying, salt-brine de-icing, pressure-wash systems, irrigation zones, water transfers, and misting or fire suppression support where a compact, battery-driven pump is required.

• Agricultural spot or broadcast spraying systems
• Mobile pressure washing and mobile washdown units
• De-icing with salt brine and site maintenance sprayers
• Irrigation, water transfer, mist spraying, and auxiliary fire suppression

The unit is CE approved and backed by a two-year warranty, providing added confidence for installation in commercial and fleet applications. The automatic on-demand switch minimizes battery drain, and the quick-attach ports reduce downtime during service or hose changes.

Who is this for: Installers, contractors, and equipment managers who need a compact, reliable 12V diaphragm pump for mobile spraying, transfer, or wash systems. It suits users who value corrosion-resistant materials, easy connections, and a standard mounting pattern for quick retrofits or new builds.
