Globe 421 Impeller
This Globe 421 impeller is a direct-fit Run-Dry replacement, engineered from advanced composite elastomers and cross-checked against the OEM part numbers it replaces.

Frequently Asked Questions
Q: Will this impeller fit my pump?
Please compare the manufacturer part number and dimensions above against your pump plate or existing impeller before ordering, or send us a photo of your pump plate and we'll confirm.
Q: How long can a Run-Dry impeller run without water?
Globe's Run-Dry composite impellers are designed to tolerate brief dry running far better than standard neoprene, but they are not rated for extended dry operation — restore water flow as soon as possible.
Q: What's the difference between this impeller and the RED version?
The RED (diesel) compound is formulated specifically for diesel and oil-lubricated pump applications, while the standard compound is intended for water service; use the version rated for your pump's application.
Q: Does this impeller come with a gasket or O-ring?
Most Globe impellers ship with the matching housing gasket or O-ring included; check the specifications above to confirm for this part number.
