GAS DRIVEN
CHEMICAL INJECTION PUMP
DFF - SINGLE HEAD
The model DFF chemical injection pumps are designed to be driven by pressurized gas. These positive displacement pumps have removable fluid ends with interchangeable check valves. All moving components are enclosed requiring no lubrication providing low maintenance and excellent reliability.
These pumps are available in various materials and piston sizes to meet your specific chemical injection requirements. They can also be equipped with chemical tanks and an optional exhaust gas recovery (EGR) to capture exhaust gases.
For decades, Western Chemical Pumps model DFF pump has demonstrated reliable engineering and design, earning the trust of its users through rigorous testing and proven performance.
