Metering and Dispensing pump headsPump Heads

FMI's Metering Pumps and Dispensers offer a high degree of accuracy and are used in a wide variety of applications where precision is required. In addition, because they have a ceramic and PVDF fluorocarbon fluid path, FMI's pump heads offer excellent chemical resistance.

FMI Metering Pumps and Dispensers are modular in design.The Pump Head Modules can be easily removed for cleaning or replaced with a spare pump head for use with different fluids. When ordered together, Pump Drive Modules, Pump Head Modules, and options are mounted, tested and shipped as one unit . FMI pump heads are made from various materials of construction for use in most applications.  Click here for Pump Head Materials of Construction.  For help with a specific application or for custom design support, use our  “Live Help”, for a direct connection to Fluid Metering’s application experts, or use our secure Application Request Form to provide us with details of your project.
