CD500M Dri-Prime® Pump
The CD500M features the unique Godwin high
pressure oil bath mechanical seal design. This allows
for totally dry running for indefinite periods while
automatically priming and repriming. Able to
perform in the toughest conditions, the CD500M
can handle solids up to 80 mm in diameter. This
makes it an extremely effective pump, suitable for
both slurry and clean water applications. The
powerful CD500M has proven itself a pump of
choice for mines, quarries and many other high
capacity applications.
