It's good to get measurements of the area around the
mixer and shaft sections to create an installation plan
prior to starting installation. Shaft sections can be long
and heavy. It works best to get them staged in the tank
prior to installing your drive unit. The use of a shaft
catcher to suspend the weight of the shaft while
lowering your drive down can be a helpful aid in
installation.
Your drive unit (reducer, motor, stub shaft and HS
couplings) will (typically) come preassembled from
the factory. It is ok to leave it assembled as you
assemble the rest of the mixer to it. Make sure to
have all of your hardware and tools handy for
connecting the mixer sections together. Torque all
the bolts to the required values to help keep the
components aligned.
ASSEMBLY OF TOP ENTRY MIXERS
The RXT and APD models are mixers that mount to the top of a tank, possibly by a
flange connection to the tank nozzle or suspended on beams above an open top
tank.
All RXT and APD models are designed and built custom to the requirements of
each individual process. It's possible the mixer you are installing will look different or
have additional or fewer components than what is shown in this manual. This
manual covers basic installation of our most common designs.
The size of your mixer is directly effected by the tank volume, tank shape, desired
level of agitation and fluid viscosity. Some mixers are supplied with a single direct
input mixing shaft and single impeller while other larger agitator set ups come with
multiple shaft sections, multiple impellers, steady bearings assemblies, etc. You can
refer to your approval drawing for the specifics of your agitator.
The following steps must be completed in order to make sure your top mounted
mixer is assembled correctly:

Multiple impellers assemblies shown. These can be installed
last once the drive end and shafting are secured in place.
Be careful when assembling the impellers. Once the tank is
filled and the impellers are submerged it's not easy to get
back to these to make adjustments.
Seals are the most delicate components in the installation of
an agitator. It's very important that if you have a mechanical
seal, to follow the manufacturers installation instructions
(provided or available online). Do not rest weight on the seal,
do not suspend any of the mixer's from the seal and don't
bang the seal around. Seals have many small, delicate inner
workings that can be easily damaged.
