NEW SINGLE STAGE NORDBLOC.1
HELICAL GEAR UNITS
NORD DRIVESYSTEMS has
extended its range of single stage
NORDBLOC.1 helical gear units
with three larger sizes. The new
drive units provide high output
torques as well as maximum radial
and axial load capacity.
With its single stage NORDBLOC.1
helical gear units the NORD
DRIVESYSTEMS range includes
innovative drive units with high
efficiency and long service life. The
drive specialist has now extended
its successful series with three
larger sizes.
The three new products SK 871.1,
SK 971.1 and SK 1071.1 have
powers from 0.12 to 45 kW and
cover the torque range up to
1,000 Nm. Thanks to optimised
bearings, they can reliably handle
large axial and radial forces. The
robust, cast iron gear units are
therefore optimally suitable for
pumps and agitators.
The innovative NORDBLOC.1
helical gear units impress with
their high efficiencies, compact
design and ultimate reliability.
They do not have any separating
joints or closing caps. This
increases the stability of the
product and at the same time
provides a smoother surface on
which neither liquids nor solid
materials can accumulate. The
FEM-optimised UNICASE housing
ensures maximum strength and
rigidity.
The modular design provides
wide application flexibility due
to numerous configuration and
mounting options. All variants are
available as flange mounted (B5
or B14), or foot/flange mounted
versions. Options for IEC and
NEMA motor mounting as well
as a wide range of equipment
variants for shafts, bearings
and lubrication can be flexibly
implemented.

FIRECHEK ® HEAT ACTIVATED
SHUT-OFF VALVES: TESTABLE,
RESETTABLE, SELF-ACTIVATING,
EASILY RETROFIT
Any spring return pneumatically
operated API 607 rated valve can
be transformed into an emergency
shutdown valve with the simple
addition of a FireChek shutoff.
Adding the FireChek enables
the valve to perform emergency
shutdown while maintaining its
original process functionality,
whether on/off or modulating.
When the FireChek senses excessive
heat from a nearby fire, the memory
shape alloy undergoes a phase
induction change and produces the
force and motion to immediately
close the air supply line preventing
the air from feeding the fire. It
simultaneously vents the spring
return actuator to allow the return
to fail-safe position-no other power
source is involved.
