SAM™ (Submersible Aerator-Mixer)
.
From the bottom up, the advantages stack up in favor of the AquaTec
SAM™:
|
|
|
• The base consists of only small
support
feet, suitable for installation ONLY in a hardened basin and subjecting
the impeller to ingestion of bottom objects.
• The impeller has a tall conical design and a large
gap between
the impeller and volute, sacrificing mixing power and the shear of air
bubbles at the point of air introduction.
• The competitor's gearboxes are double reduction
helical units
which have a typical efficiency of 90% and a lower tolerance for shock
loading than planetary gear reducers. The helical reducer
transmits
only 27,500 ft/lb per second.
• The competitor's drive unit exposes the output
shaft at the lower end of the gear reducer directly to the process
liquids in the basin.
• The competitor's drive unit employs a thermal
switch in the
motor winding to enable the controls to turn off the motor in case of
overheating.
• The competitor's drive units have NO ability to
sense moisture
in the gearmotor. Your very first indication of a moisture
problem
could be complete loss of the drive.
• The competitor's drive units are available to 50HP
maximum,
requiring additional units in basins requiring more mixing power and/or
aeration.
• The competitor's unit offers a lifting bail
requiring the
entire mass of the unit, power cable, and air hose to be hoisted by the
end
of the motor and through the gear reducer.
• The competitor's offer units which are unable to
perform
mixing without aeration in sizes from 5HP to 50HP, and all other sizes
are
derated for mixing-only duty.
• The competitor's units must operate at depths of 4M
for smaller units and 8M for sizes above 40HP.
|
• The AquaTec SAM™ has a full
circular
base suitable for installation in any tank, basin, or lagoon. The
circular base also helps prevent erosion of soft footings.
• The AquaTec SAM™ uses a large diameter close
tolerance
impeller which provides substantial pumping action, providing
improved shear and mixing of the air delivered to the unit.
• The AquaTec SAM™ employs a heavy duty, high
efficiency planetary gear reducer
with a significantly greater
tolerance of shock loading. The SAM gear reducer can transmit
power up
to 41,250 ft/lb per second (737 ft/lb continuous).
• The AquaTec SAM™ includes a secondary,
redundant seal and secondary, redundant oil chamber to
isolate the reducer completely from liquids in the basin.
• The AquaTec SAM™ offers multiple thermal sensors
which allow
the controls to either reduce load to provide cooling while maintaining
mixing
and aeration, or shut off the motor.
• The AquaTec SAM™ includes a moisture sensor in the
drive unit
to help prevent catastrophic failure of the gear reducer and motor in
the event of moisture intrusion.
• The AquaTec SAM™ is available to 75HP, allowing
mixing and
aeration suitability with a single unit in basins requiring more mixing
power than the competition.
• The AquaTec SAM™ has a robust retrieval system
connected to
the machine base to safely support the full load of hoisting, including
the cables and hoses.
• The AquaTec SAM™ includes a standard pre-programmed
solid state
electronic control to maintain constant power under all ranges of
mixing or aeration conditions.
• The AquaTec SAM™ can operate at minimum depths of
78" (less than 2M) in all size ranges. |

AquaTec SAM™
The knockout punch...
The AquaTec SAM™ Submersible Aerator-Mixer is designed, engineered,
fabricated, and assembled in the USA. The AquaTec SAM™ uses a
proven and robust Reliance Electric Duty Master™ submersible electric
motor drive unit built in the USA. The standard electronic solid
state control and moisture detection controls are built in the
USA. All AquaTec SAM™ units are supplied with fully synthetic
gear and seal case lubricants.
Special units can be constructed for duty in higher temperature
applications and up to 150HP with torque ratings to over 95,000 ft/lb
per second (over 1,250 ft/lb continuous).
AquaTec maintains an inventory of repair and replacement parts and
supplies for rapid delivery and maximum uptime.
