Helwig Carbon
BPK™ - THE INDUSTRY'S BEST SHAFT GROUNDING SOLUTION
Stop the frustration of bearing
damage caused by VFD currents
with Helwig Carbon Products'
industry-best BPK Shaft Grounding
Solution. Our proprietary Silver
Graphite Brush provides superior
protection for over ten years-with
no maintenance required. Helwig's
BPKs (Bearing Protection Kits™)
deliver unbeatable shaft grounding
performance, far outlasting and
outperforming carbon fiber rings.
HELWIG BPKS PROTECT FOR
THE LONG HAUL
Helwig BPKs are proven to protect the
bearings exceptionally for 10+ years
under typical operating conditions-
outlasting the motor. BPKs mitigate
shaft voltage to <1V peak-to-peak,
providing outstanding long-term
protection. In contrast, carbon fiber
rings have been proven in numerous
tests and real-world applications
to fail quickly. They start out with
adequate protection but in six months
to a year, shaft voltage readings
typically increase to damaging levels.
HELWIG BPKS REQUIRE NO
MAINTENANCE
Once installed, Helwig's proprietary
silver graphite brush maintains
optimal grounding with no
maintenance, even in contaminated
environments. Silver graphite
brushes have a cleaning property
that, when combined with positive
spring force, provides a contaminantfree
brush track for optimal shaft
grounding. Carbon fiber rings
require downtime for repainting of
colloidal silver every six months
to a year and require replacement
when the carbon fiber bristles wear
and no longer make contact with
the shaft. Carbon fiber bristles are
also susceptible to contamination,
disrupting the ground path and
rendering them ineffective.
HELWIG BPKS REDUCE
YOUR INVENTORY
One BPK model can fit many shaft
sizes, so you can protect all your
pumps easily.
