The MARCH Model TE-5 is similar in nature to the AC-5 in that
the performance is the same and most of the parts are
interchangeable. It is the beginning of the highly corrosive
series and the first pump that an impeller trim is available for
solutions with a specific gravity of 1.0 or more. The complete
nomenclature of the TE-5 pump, as with all MARCH pumps, requires
some explanation. The term "TE" indicates a highly
corrosive pump with an encapsulated impeller magnet assembly and
compatible "O" ring; and second, the TE indicates that
the motor is totally enclosed fan cooled. It should be noted here
that other motors are available for this model, such as air
cooled, explosion proof and submersible. In some cases, letter
portions of the nomenclature are a designation of the wetted
material that will come in contact with the solution that is to
be pumped. The "C" in the model number, in it's origin,
indicated that the pump was manufactured with threaded
connections. However, the "K" is an indicator of Kynar
material (PVDF) and lastly the "S" signifies a metallic
pump head of 316 stainless steel.
All series 5 pumps are available with either threaded or hose
type connections. The exception is the stainless steel version;
flanged or threaded connections are available.
As with all MARCH pumps, the latter two letters of the model
number (MD) indicate that the pump is magnetically coupled to the
motor.
All TE models have two things in common; a TEFC motor and an
encapsulated impeller magnet assembly. There are major
differences between the C, K, and S models in the wetted
materials, type of bushings and "O" rings. Materials of
construction are of a wide variety and are unique to each model.
The standard TE-5C-MD pump wet end is made of glass filled
polypropylene and the impeller assembly is of polypropylene. The
bushing material is also of polypropylene. Both the spindle and
the front thrust washer are of high grade ceramic. The standard
"0" ring for this model is VitonŽ.
The TE-5K-MD is designed to handle difficult solutions and the
variations in internal components are similar to that of the C
model.
While performance and motor are the same, the TE-5S-MD wet end
assembly and impeller magnet assembly are manufactured of 316
stainless steel. The carbon bushing allows the pump to handle a
wide variety of solutions and affords a dry run capability not
found in other models. Other bushing materials are available as
well as numerous types of "O" rings. The standard
spindle is ceramic; a stainless steel spindle is available. The
TE-5S-MD does not utilize a rear washer.
It should be noted that the stainless steel number S is
shipped from the factory with the impeller magnet assembly in a
separate carton. This is necessary to avoid damage during
transport.
Variations in wetted materials on the TE-5 are some of the
widest in the MARCH line. Most components are interchangeable
from one number S to another. This affords maximum compatibility
with a wide variety of solutions.
Uses for the TE-5-MD pump are numerous and varied; some of the
more popular applications include computer cooling, circulation
of photographic chemicals and transfer of highly corrosive
chemicals.
