2 General Information
2.1 Mixer description
Casing - Casings are side suction, side discharge, back pull-out designs, utilizing a spacer coupling to
allow for one craft maintenance. The alignment fit is protected from the pumpage with a confined gasket
between the casing and the seal chamber cover.
Rotor - The fully open multi-vane rotor is supplied on all mixers. It is engineered to effectively open and
loosen the fiber network to provide complete and efficient chemical or gas mixing. The rotors have been
designed to handle the tough medium consistency paper stock services. The rotor is keyed to the shaft
and held in position by a rotor locknut, sealed by a PTFE O-ring and secured with setscrews. The sleeve
side of the rotor is sealed by a PTFE O-ring for a dry shaft design.
Shaft Sleeves - The sleeve is a renewable hook type, positively driven by the rotor key. One end is free
to expand due to possible temperature variations. A PTFE O-ring prevents leakage under the sleeve.
Power End - The heavy duty bearing frame and housing are both constructed of cast iron. The frame is
bolted and rabbeted to the seal chamber. The inboard bearing (cylindrical roller) carries radial loads only
and is free to float axially within the bearing frame. The outboard bearing is 40° angular contact duplex
set mounted back-to-back, locked on the shaft by a threaded locknut and carries both radial and axial
loads. The frame is sealed with labyrinth seals as standard. Flood oil lubrication is standard. Grease lu-
brication is available as an option. No special parts are required to convert from grease to oil lubrication.
Bearing frame cooling can be supplied as an option with oil lubrication.
Seal Chamber - The seal chamber is especially designed for medium consistency mixing applications. Its
wide open design keeps the stock flowing without de-watering and binding the seal.
Hardware - All fasteners and tapped connections are metric.
Direction of Rotation - Clockwise (right hand) as viewed from the driver looking at the mixer shaft.
2.2 Nameplate information
Every mixer has two Goulds nameplates that provide information about the mixer. The tags are located
on the casing and bearing frame. When ordering spare parts you will need to identify the mixer model,
size, serial number, and the number of required parts.
Mixer Casing Tag - provides information about the mixer's hydraulic characteristics, see Figure 1: Mixer
casing tag - English on page 10 and Figure 2: Mixer casing tag - metric on page 10 .
Bearing Frame Tag - provides recommended type of lubrication the mixer, see Figure 3: Bearing frame
tag on page 10 .
