Preform epoxy
Multi-Seals Inc., Manchester, Conn.
|
Uniform epoxy is an alternative to
liquid epoxy for high-volume, high-quality epoxy sealing applications. These
preforms are one-part epoxy resins that are solid at room temperature. When
heated, they melt and cure, forming a consistent seal that protects components
from dust, moisture, oil, flux, solvents, conformal coatings, and other
contaminants. Close tolerances on preform configurations, consistent premixed
ratios of resin to catalyst, and consistent viscosity from beginning to
end of batch ensure uniform, high-quality results, according to the manufacturer.
Preforms can be dispensed as rapidly as 200 to 600 parts per minute with
little or no operator training, and extensive operator experience is not
required to produce uniform results.

Trans- former oil pumps
Unifin International, London, Ontario
|
Unifin's line of transformer
oil pumps is manufactured under the company's Cardinal brand. To
meet the extreme temperature requirements, the pumps are rated for continuous
duty operating temperature ranges from -40°C to 100°C. The
Cardinal pumps also have other features for transformer oil applications,
such as the capability to permit thermo-siphon flow when the pump is not
operating, allowing natural convection even when the pump is completely
shut off. For long life in the field, all Cardinal pumps offer rugged split
casing design with heavy-duty class 30 cast iron used for the pump casting,
motor enclosures, impellers and volutes. Cardinal pumps are low maintenance
and long-lasting. With no mechanical seals, repair and upkeep are reduced
to using two gasket seals on each pump. The pumps are durable and resilient
because transformer oil can flow back through the motor and bearings, providing
cooling and lubrication.

Temper- ature meter
Omega Engineering Inc., Stamford, Conn. |
Heavy-duty Atlas MaxTite blind threaded inserts feature a thicker head and
heavier wall than standard types to serve in demanding high-load applications.
These fasteners provide permanent metal threads in "blind" attachment applications,
where only one side of a workpiece is accessible for fastener installation
and final component assembly. These inserts are practical alternatives to
tapped holes, weld nuts, rivets, and self-drilling or tapping screws, and
can be installed permanently anywhere using a hand-held portable tool. An
added advantage, according to the company, is that during fastener installation,
several thin sheets of dissimilar materials can be assembled and then final
components can be attached, saving production steps, time, and costs.

Split seal
Flowserve Corp., Dallas, Texas |
The PSS III is the company's
next-generation single pressurized split seal. Designed for pumps and mixers,
it is suitable for use in paper mills, wastewater treatment facilities,
soda ash processing, and light chemical plants. Compared to competing split
seals, replacement of the PSS III is fast and easy in difficult-to-service
equipment applications, according to the company. All fasteners and gaskets
are captured in four major components, simplifying installation and aiding
first-time installation success. The pump and primary driver on the PSS
III don't need to be completely dismantled during seal maintenance
because the seal installs around the shaft and outside the seal chamber.
Installation tools are included with the seal, and only one wrench is required
for the gland bolts.

Case drain monitoring
Hedland, Racine, Wis. |
Unexpected pump failure can be costly
and time-consuming. According to the company, by installing a Hedland direct-reading
flow meter on the pump case drain, the user can monitor changes in efficiency
by keeping tabs on any increase in case drain flow. The excess case drain
flow shows the pump is beginning to fail. This lets the user schedule preventive
maintenance and reduce unexpected downtime. The variable area meter has
a low pressure drop, typically 1-5 psig with an accuracy of 2 percent of
full scale. The meter can be installed in any position without a need for
special piping or flow straighteners.
