Sealless, Non-Metallic Pumps for Crucial
Liquid Containment Applications |
 |
 |
CMD Mag Drive Series'
outer magnets are turned by a motor, and their magnetic force passes through
the hermetically sealed canister causing the rotation of the Mag Drive's
inner magnets. The inner magnets turn the drive gear shaft, which turns the
driven gear, carrying the liquid from the suction to discharge port. The CMD
Series pumps combine a proven design with state-of-the-art engineered
composites for a structurally rugged, reliable, simple-to-service pump with
a lower cost of ownership. |

The Viking® Advantages |
|
Advanced Durability |
|
Viking’s CMD series external gear pump is made of engineered
fluoropolymers with superior corrosion resistance and strength over a broad
range of chemicals and temperatures. Its sealless design eliminates
potential leak points, as well as the eddy current energy loss and heat rise
common in metallic pumps. Fully encapsulated, self-aligning magnets
use patent pending spline design allowing them to "float" on the drive shaft
without inducing axial loads, extending service life. With short-term
run-dry capabilities supplied by a patent pending bearing design, the CMD
series has built-in protection during system upset conditions such as closed
suction valve or empty supply tank. |
|
Ease of Installation |
|
A unique, universal flange design provides easy installation
to both ANSI and DIN flanged systems alike. Its robust construction and
rigid pump base with slotted holes makes retrofitting of existing
installations simple. The close-coupled mounting eliminates the
traditional alignment issues with pump and motor for quicker, easier
installation. The CMD Series' modular design of magnet hub provides
one drive magnet per pump size, with interchangeable adapter-hubs to fit
both standard NEMA and IEC motors. |
|
Application Flexibility |
|
Viking’s CMD series' non-metallic construction delivers a
broad range of chemical compatibility. Its sealless design provides
trouble-free performance where liquid containment is crucial to
environmental requirements. This pump series is ideally suited for
low-flow operation where centrifugal pumps perform inefficiently and can
experience cavitation, increased radial loads and unstable flow.
Designed with simple serviceability in mind, you can replace all of the
typical wear components easily by removing only the front cover, maximizing
uptime. |
|
Lower Cost of Ownership |
|
Non-metallic construction eliminates the need for expensive
alloys. Sealless design eliminates service requirements of mechanical seals
and expensive seal flush systems. Run-dry capabilities provide protection
against system upsets without catastrophic failure. Advanced design utilizes
fewer parts (16 fabricated parts) minimizing maintenance time and inventory
requirements. Patent pending casing liner transfers wear from casing to
replaceable liner, which is part of the recommended spare parts kit, to
provide cost-effective, 100% renewal of CMD pump efficiency and performance
for a lower total cost of ownership. |
