Whether you're maintaining vehicles in a busy garage or handling chemicals for shop tasks, Everflo Chemical Pumps deliver the performance and durability you need. This category features two standout 12V diaphragm models designed for efficient, safe transfer of chemicals, making them essential tools for automotive enthusiasts and professionals alike.

Why Choose Everflo Chemical Pumps?

Everflo has built a strong reputation for producing rugged, high-quality pumps that stand up to demanding environments. Their chemical pumps are engineered with chemical-resistant materials, ensuring longevity even when transferring harsh substances like antifreeze, brake fluid, or cleaning agents. What sets Everflo apart is the combination of powerful flow rates, self-priming capabilities, and easy integration into 12V systems—perfect for mobile setups in the Garage & Shop category.

These pumps excel in scenarios where precision and reliability matter, from fleet maintenance to DIY projects. Shoppers appreciate their black, compact design that fits seamlessly into toolboxes or custom rigs without drawing attention.

Key Features to Consider

When selecting an Everflo Chemical Pump, focus on these critical specs:

  • Flow Rate: Options range from 5.5 GPM for lighter duties to 7.0 GPM for faster transfers.
  • Ports: Standard 1/2" FNPT connections for straightforward plumbing.
  • Power: 12V DC compatibility for battery-powered operation in vehicles or portable generators.
  • Diaphragm Design: Prevents leaks and handles viscous fluids without clogging.
  • Durability: Chemical-resistant housing withstands corrosion over time.

Buyers should match flow rate to job volume—lower for spot checks, higher for bulk tasks. Also, verify compatibility with your hose setups within the broader Barrel & Hand Pumps selection.

Comparing Everflo Models

Everflo offers two primary models in this category, allowing easy choice based on your needs.

The EF5500-BOX provides a solid 5.5 GPM flow, ideal for moderate chemical transfers like topping off reservoirs or small-batch dispensing. Its balanced performance suits intermittent use, such as in home garages or light commercial work, without overwhelming power draw on 12V batteries.

For higher volume demands, the EF7000-BOX steps up to 7.0 GPM, accelerating transfers for larger jobs like draining barrels or servicing multiple vehicles. Both share the same robust diaphragm technology and port sizing, but the EF7000 edges out in speed, making it preferable for pros who value efficiency.

Choose the EF5500 if portability and energy savings are priorities; opt for the EF7000 when time is money. Both are boxed for protection during shipping and storage.

Common Use Cases

Everflo Chemical Pumps shine in automotive applications:

  • Transferring coolant, oils, or cleaners between barrels and machinery.
  • Workshop fluid management for brake systems or power steering.
  • Farm or fleet maintenance where 12V power is readily available.
  • Emergency roadside chemical handling without needing AC outlets.

Integrate them with other tools in Tools & Equipment for a complete setup. For alternatives, explore brands like Chapin in our Chapin Chemical Pumps or TERAPUMP options.
