Magnetic Stirrers / Magnetic Mixers / Magnetic Agitators

Impeller Designs

An extensive selection of stirrers/mixers is available with your PUMA magnetic drives. Impeller options include but not limited to flat & pitched blades, single and double helical ribbons, anchors, gas dispersion and specials.

Three Impellers

Through Bore Magnetic Drives:

PUMA magnetic drives mixers use a through bore design utilizing three identical support bearings, eliminating the need for multiple spare parts. This feature also simplifies in cleaning and the maintenance of drives, which results in the reduction of maintenance costs.

Drive Motors

A wide selection of TEFC, Explosion-Proof, AC/DC, and air driven variable speed motors are available to operate the magnetic mixer or magnetic stirrer fixed or variable speeds. Horse power range from 1/8 hp to 8 hp to meet the agitation/blending/stirring system torque and speed requirements.

THE Flexible Connection: With PUMA drives, the options are endless….

We work hand in hand with our customers to provide the optimal mounting solution. PUMA drives magnetic mixers and magnetic stirrers come with standard, threaded vessel connections that must be machined into an existing vessel. We will custom manufacture alternative mounting solutions to accommodate specific customer requirements. These include, but are not bound by:

• ANSI flanged mounting arrangement.
• Custom flanged or threaded configurations to adapt to an existing opening or nozzle style.
• Sanitary connection

Compatibility to meet your processing needs:

PDC PUMA Drives can be manufactured from most machinable alloys to ensure compatibility with the intended process media. These include:

Metals

• 300 series SS, Hastelloy^®, Monel^®, Inconel^®, titanium, and many more machinable alloys for use in corrosive processes. Non-metallic coatings are available.

Static seal types

• All types of elastomeric o-rings
• Spiral wound gaskets from acceptable alloys and fillers
• Lens rings from high temperature applications

Bearing materials

• Carbon graphite
• Various grades of Rulon^®
• Non-lubricated, anti-friction ball bearings for special applications

Speed Control System

• Proprietary speed sensor technology measures the speed of the drive internals. This insures accurate measurement of the drive movement and will detect the event of a magnetic coupling failure.

• Speed-control panels complete with programmable VFD and digital speed indicator with control outputs via customer control system.
