Kop-Flex KD disc couplings reduce overall operating costs... period. With no
wearing parts or lubrication required, Kop-Flex KD couplings dramatically reduce
coupling maintenance, so you can focus on other mill concerns. No more late night
phone calls about gear coupling failures due to lubrication – with your new Kop-Flex
KD couplings, it’s possible to inspect the flexible discs without shutting down your
equipment – a feat not possible with gear couplings.
Proven Cost Savings
At one paper mill working with Kop-Flex, the labor cost per shaft was calculated at
$600 per year with an additional $87 per year allocated toward grease and O-rings
for existing gear couplings. With 144 gear couplings in service at the mill between
two lines, a complete interchange to KD couplings could yield a savings of $98,928
per year in maintenance costs.
Maximize ROI with KD Disc Couplings
By accounting for labor rates, maintenance costs, maintenance schedules and required
parts and lubricants, your Kop-Flex representative can demonstrate the ROI resulting
from changing-out gear to disc couplings in your mill.
Additional Savings Offer
For a limited time, get 20% off on any KD coupling that replaces a competitor’s
coupling.
