These proven, rugged, accurate pumps are used in many industrial plants for injecting a controlled flow of highly reactive liquids. Heavy duty industrial grade construction means these pumps will deliver many years of trouble free 24-7-365 pumping.

The valve assembly on Madden MF series diaphragm metering pump is the driving force for repeatability and accuracy. Check ball valves on the suction end and discharge end of the assembly allow for precise amounts of volume to pass through the solution head. Check out the PDF drawing below for details of construction.

• MF Series pumps are designed for ±1% steady state repeatable accuracy over a 10:1 turndown range.
• Manual output control knob is located on top of the pump for easy access.
• Automatic pump output control is available for pumps equipped with a variable speed motor. Industrial grade worm gear reducer is integral with the pumping mechanism. Precision internal pump parts run in an oil bath for extended service life. No external lubrication required.
• Double diaphragm option is available for superior protection from dangerous liquids. When equipped with the proper materials the MF Series pumps are excellent for pumping dangerous liquids such as acids, caustics and solvents. Liquids with suspended solids such as diatomaceous earth and lime slurry can be accurately pumped.
• Tough fabric reinforced rubber diaphragms protect the drive train from the pumped liquid. The short stroke with 3″ diameter piston increases diaphragm life by reducing fatigue.
