Because even a 1mm variation in wall thickness can impact
hose life by 25%, every hose is precision machined to
ensure repeatable performance.
The hose is the key
The machined hose is the single most vital component for the performance,
durability, and efficiency of the hose pump. To ensure perfect compression
and consistent, reliable performance, Bredel manufactures hoses
from high quality compounded rubbers, reinforced with four
individual layers of braided nylon and finished by high
precision machining. Perfect compression eliminates
slip which, in other pumps, can destroy shear
sensitive product, reduce metering accuracy,
or allow abrasive slurries to wreak havoc
on wetted parts. Bredel engineers
hoses to meet the flow, pressure
and temperature characteristics
of your toughest applications.
Designed to perfection
Bredel is on the cutting edge of technology to
engineer, manufacture and test our pumps.
Innovation: As the global leader in hose pumps,
we pride ourselves on new ideas and innovative
products that bring the benefits of hose pumps
to our customers in an ever expanding range of
applications. For example, retractable pressing
shoes bring ultimate clean-in-place capability.
Design: Using tools like finite element analysis
(FEA), we design our hoses to perfection - right
down to the position of the reinforcing layers,
angles and thickness of the cord reinforcement,
and the thickness of the rubber. Everything
from the geometry of the pressing shoe to the
pump housing is engineered to optimize the
performance of the hose.
Production: Unique in the world, Bredel’s state-of-
the-art automated hose grinding facility machines
every hose within fine tolerances - guaranteeing
proper compression for efficiency and longevity.
At our ISO9001:2000 factory, each pump and hose
is constructed to the most rigorous quality controls
standards.
Hose construction
The essential component of high-performance
hose pumps is a hose that is constructed of layers
of rubber reinforced by winding several layers
of nylon cords. The inner and outer layers are
extruded. The inner layer is available in a range of
rubber compounds. After the hose is constructed,
it is then machined. Machining is the final step
in hose manufacture and is critical to insure that
exact tolerances are held.
Precision hose ensure
• Tight tolerances for low stress on bearings
• Perfect compression for long life
• Consistent capacity independent of varying
suction and discharge conditions
