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 for use in most applications.
See Pump Head Materials of Construction for configuration details.
