⻬ Mix with a Non-Vortexing,
Non-Aerating Action
FMXD11 mixers efficiently mix from 
the top of a 55-gallon drum to the 
bottom, without requiring removal of 
the drum lid. The optional IPS drum 
bung adaptor allows fixed mounting 
of the mixer to the drum. Mixers 
draw approximately 14 gallons of 
liquid (750 cp max viscosity, 1.8 S.G. 
max density) per minute through 
the 2" diameter mixing tube. Fluid 
temperature range is 0 to 93°C 
(32 to 200°F).
A shaft-mounted turbine inside the 
mixing tube rotates at 3450 RPM 
(from 300 to 3000 RPM for the air 
motor), creating a steady suction 
effect at the four upper intake ports. 
Liquid is forced down through the 
tube and forcefully expelled through 
the ports at the bottom of the tube, 
breaking up and dissolving settled 
particles (maximum solid size is 1⁄8").
FMXD11 mixers work with a 
non-vortexing, non-aerating action. 
The mixing tubes are just under 
1 m (38") long. They have PTFE 
bearings at the center and base of 
the tube, and a graphite-filled PTFE 
seal. The shaft, turbine, mixing tube, 
and sleeve are 316 stainless steel. 
Mixers are available with either 
an air-driven or electric motor. 
Note: Use the air motor and the FMXD3-SK 
static protection kit for mixing flammable 
materials or in explosive environments.
CAUTION: 
DO NOT USE THE AIR MOTOR
WITHOUT THE FMXD3-SK 
ANTI-STATIC PROTECTION KIT

The air-driven 
⁄4 HP motor  
operates with 10 to 15 CFM air 
at 3.4 to 6.2 bar (50 to 90 psig), 
and includes a flow regulator 
and muffler. 
Note: Use a filter/regulator and lubricator 
in the air supply line if the air is not filtered 
and lubricated.

The TEFC electric 1⁄4 HP 
motors are thermaloverload protected, 
and come with an on/off 
switch and a 3.6 m (12') 
three-wire cord with plug 
(FPUD421 supplied 
without plug).
