The
Norstone® Polymer Impeller
The
Norstone® impeller is the answer to the negative issues which
are inherent in metal blades when dispersing certain types of
slurries. It is constructed from polyurethane for non-explosion
proof applications such as water and oil based products or anti-static
UHMW (Ultra High Molecular Weight) Polyethylene for explosion
proof applications such as alkyd and lacquer products. These blades
are USA manufactured and customized to fit any shaft configuration.
Sizes start at 1 3/4" diameter.
Abrasion
Resistance: This
impeller is excellent for abrasive products such as ceramics,TiO2
and oxide pigments, cement, ferrite, silica and others since
it outlasts metal blades due to the wear resistance properties
of the polymer. It lasts at least 10 times as long as metal
blades and longer than other plastic blades in the market. If
you don't believe it we offer you the first blade on a 30 day
free trial basis.
Contamination:
This impeller will
not contaminate your product with metal or the discoloration
caused by metal because there is no metal in the blade's construction.
Rejected batches are decreased.
Safety:
This impeller never gets sharp no matter how worn it becomes
unlike metal blades which develop razor sharp edges making them
dangerous to change or when they sit above the tank level. They
are also reversible or bi-directional and can't be put on backwards.
This also means that when the trailing edge wears out, turn
it over and the leading edge becomes the trailing edge performing
like a new blade.
Improved
Production Time: This impeller does more work in
less time because its third dimension provides a high torque
output producing an aggressive dispersing action; it actually
speeds up production for faster batch turnaround. This difference
is even more dramatic with higher viscosities as the axial flow
is 7 times greater than a steel impeller. These impellers can
be sized 1"- 2" lower in diameter than metal blades being replaced.
You save on labor and downtime because the impeller speeds up
production time with far fewer blade changes.
Cost:
This impeller initially costs more than a metal blade, however,
it has a low cost to wear ratio. In the long run these blades
are outright less expensive but added to that is a cost savings
due to lower maintenance time required for blade changes.
Fawcett
Mixing and Dispersing Impellers
Mixed
Flow Impeller
Our
most popular impeller for slow speed mixing up to 200 gallons
assuring that material is mixed in all directions. Available
in regular and high vein with or without collar and set screw.
This blade is more effective than a standard 3 bladed prop type
blade.
CSI
Ring Blade
A patented design
using the Venturi principle to produce very fine grinds with
laminar flow and less heat build-up. Also excellent for emulsification
when operated at low speeds.
