GRACO Z Pump L040S8 40cc High Wear Metering Pump

The L040S8 is a Z-Series precision metering pump designed for accurate material dispensing in two-component processing systems.

Featuring a 40cc displacement and S8 Elite High Wear configuration, this pump provides improved wear resistance and consistent volumetric output for demanding adhesive, sealant and coating applications.

Unlike conventional fluid transfer pumps, the Z-Series is designed for controlled material metering where precise ratio accuracy and repeatable dispensing performance are required.

The L040S8 can be combined with another Z-Pump size to achieve different material ratios according to system requirements.
