This manual should be used to facilitate the installation, start-up, operation and maintenance of your Plenty
Side Entry Mixer.
A good knowledge of the m ixer, together with a planned preventative maintenance program, will ensure
optimum performance of your mixer. Inform ation required to operate and maintain your mixer can be found
in this m anual.
Plenty Side Entry Mixers are designed for use in oil production, refining and distribution industries for
blending, homogenizing, maintaining temperature uniform ity, tank cleaning and minim izing sludge build-up.
The mixer is bolted to a connection nozzle or flange located on the side of a storage or blending tank.
The Plenty Belt Drive Side Entry Mixer is driven by an electric motor, m ounted to the m ain mixer body
(fram e) by m eans of a mounting plate which is hinged relative to the mixer body, allowing the drive belt to be
correctly tensioned.
Standard Plenty units are furnished with a toothed, synchronous timing belt. This belt will not support
combustion and provided that it is properly aligned and tensioned, will not generate sufficient heat to self
ignite. The motor (drive) pulley and the m ixer (driven) pulley utilize taperlock bushings to lock them in
position on their relative shafts. The belt drive components are totally enclosed within a non-sparking guard.
The main m ixer body is a rigid, one piece iron casting, which houses grease lubricated sealed for life radial
and thrust bearings selected to have in excess of 50,000 hours operating life. The m ixer body is connected
to a mounting flange/m echanical seal assem bly through which a m ixer shaft passes. The mating taper
between the m ixer shaft and the mounting flange provides a shut-off device which enables m echanical seal
and/or bearing replacem ent without the need to com pletely drain the tank contents.
The mixer flange includes studs and nuts for direct connection to a standard ANSI 150lb rated flange. Units
may be fitted with a tank adapter to suit a specific nozzle or m anway drilling pattern.
The mixer shaft is fitted with a three bladed high efficiency propeller, which is connected to the shaft by
means of a locking bolt and key.
Mixer parts referred to in these instructions can be identified by referring to the appropriate Assem bly
Drawing.

instructions.
The unit has been treated with corrosion inhibitors and preservatives at the factory. Store unit indoors if
possible. In the event outdoor storage is necessary, the unit should be protected from the elem ents.
Extrem e temperature fluctuations should be avoided in storage; a norm al temperature and dry ambient
conditions will afford the best storage results.
