Closed Head 55 Gallon Drum Mixer


55-gallon drum mixers are the answer to a need to mix and suspend products throughout the product supply chain. In particular, for closed-head 55-gallon drums that have a 2″NPT port, we offer our bung mount mixer. This drum mixer is specifically designed to enter a closed-head drum tank and provide increased mixing via collapsible impellers.

Dynamix agitators and mixers are selected and configured according to your needs. These images and configuration options are only guidelines for your final mixer selection.

In order to provide our Solution Assurance we must engineer your mixer to pump the fluid properly. This pumping approach to mixing requires a larger diameter impeller. Often, barrels and drums do not allow for large-diameter impellers, so we designed a collapsible impeller. This impeller can enter the 2″ NPT port of the barrel or drum.

Big Tank Mixing in a Drum

Optimal mixing in a 55-gallon drum requires our 4-bladed collapsible impellers. These drum mixer impellers enter through the 2″ NPT openings of the 55-gallon drum. Our collapsible impellers expand during drum mixing and collapse after for easy removal. This ensures that the correct type of mixing quality will be achieved.
