Air Operated DEF Pump - OTC Tools and Equipment

The OTC Tools and Equipment 4339 Air Operated DEF Pump is engineered for efficient and professional fluid transfer in automotive and industrial settings. This robust pump utilizes compressed air to quickly dispense Diesel Exhaust Fluid (DEF), engine oil, and antifreeze from 15 to 55-gallon drums, ensuring reliable operation for professional technicians.

Key Features

• Air-Operated Efficiency: This pump uses compressed air (30 to 100 psi working pressure) for rapid fluid transfer, delivering up to 8 GPM (gallons per minute) at 100 psi.
• Versatile Fluid Handling: The pump safely transfers Diesel Exhaust Fluid (DEF), engine oil (up to SAE 50 viscosity), and antifreeze, making it suitable for multiple workshop applications.
• Drum Mounting: Designed with a built-in 2-inch bung adapter, this pump allows for secure attachment to standard 15 to 55-gallon drums.
• Adjustable Positioning: A lock nut in the pump body enables precise adjustment of the pump's position within the drum.
• Telescoping Inlet Tube: The telescoping inlet tube accommodates various drum depths with an adjustable length range of 20 1/2 inches to 36 inches.
• Controlled Air Supply: An integrated ball valve limits maximum air inlet pressure to 100 psi, protecting the pump and ensuring consistent performance.

Applications

The OTC 4339 Air Operated DEF Pump is an essential tool for automotive service centers, heavy-duty truck maintenance facilities, and industrial operations that require efficient and clean transfer of common workshop fluids. Its durable construction and ability to handle DEF, engine oil, and antifreeze make it ideal for routine fluid changes, system refills, and bulk fluid dispensing from large drums.
