SPECIFICATIONS

A FLOATING SURFACE AERATION
SYSTEM

1.0 GENERAL

1.1 DESCRIPTION

Manufacturer shall furnish a floating aeration
system capable of pumping water from below the surface of a body of
water and mixing it throughout the body of water.

A submersibl</sub></span><span class="Normal--Char" style=" font-family: 'HelveticaNeueLT Pro 35 Th', 'Arial';
font-size: 12pt;"><sub>e motor shall draw water into a propeller chamber
where it shall be pumped into the atmosphere in the form of a random
boil effect.
The water droplets shall become oxygen enriched
and return to the surface, therefore transferring oxygen from the atmosphere into the body of water.

This repeated action shall effectively mix the
body of water and distribute the dissolved oxygen continuously.

Aeration system shall include a motor in a housing,
attached to a float.  This assembly shall be connected to an electri</sub></span><span
class="Normal--Char" style=" font-family: 'HelveticaNeueLT Pro 35 Th', 'Arial';
font-size: 12pt;"><sub>cal control panel by underwater power cable,
all of which as specified in SECTION 1.2.

1.2 AERATOR COMPONENTS DESCRIPTION

Float shall be made of linear low density polyethylene,
with a minimum 14 inch (35.56cm) discharge area.  This area shall
be protecte</sub></span><span class="Normal--Char" style=" font-family: 'HelveticaNeueLT Pro 35 Th', 'Arial';
font-size: 12pt;">_{d by a stainless steel discharge guard. Four
Series 300 stainless steel brackets shall be attached to the float,
around which a protective Series 300 stainless steel intake screen shall
be mounted.  The motor housing shall be attached to the brackets
durin}</span><span class="Normal--Char" style=" font-family: 'HelveticaNeueLT Pro 35 Th', 'Arial';

Propeller
shall be precision machined and formed using
Series 300 stainless steel.  It is connected to the motor shaft
by a Series 300 stainless steel bolt.

Propeller chamber
shall be enclosed by a Series 300 stainless
steel intake screen. Screen shall be capable of keeping out any
debris which may impede the propeller</sub></span><span class="Normal--Char" style=" font-family: 'HelveticaNeueLT Pro 35 Th', 'Arial';

Motor housing shall be Series 300 stainless steel. 
1-5HP shall have a permanent Series 300 stainless steel electrical hub
welded on the side of the housing to allow electrical cable entry. The 1/2HP shall
have a Series 300 stainless steel electrical hub welded on the bottom
of the housing to allow electrical cable entry.

Motor shall contain a Series 300 stainless steel
shaft, incorporating a permanent, split ph</sub></span><span class="Normal--Char" style=" font-family: 'HelveticaNeueLT Pro 35 Th', 'Arial';
font-size: 12pt;">_{ase capacitor-run on single phase and a polyphase
induction on the three phase motors.  The rotor shall be dynamically
balanced and ball bearing supported.  The stator windings shall
be double dipped and baked with Class F insulation, designed for oil
imme}</span><span class="Normal--Char" style=" font-family: 'HelveticaNeueLT Pro 35 Th', 'Arial';

refined mineral oil of food grade quality, specially formulated for
lubrication.  It shall meet FDA regulations. The oil shall provide
continuous lubrication of bearings and internal seals and further function
as an efficient heat transfer medium, allowing
the motor to operate at 1437 RPM, at relatively low temperatures. 
The motor shall be contained in the motor housing by a Series 300 stainless
steel top plate.
 


Seals used to protect the motor against water or

assembly, composed of silicon carbide and Series 300 stainless steel. 
All elastomers shall meet UL 778 and CE requirements.  This assembly
shall then be encapsulated and protected within a Series 300 stainle}</span><span

Underwater power cable shall be UL Listed and specifically designed
for underwater use.  The conductors are flexible, stranded copper
wire sized for the amp draw and length of run.  The conductors
shall be resistant to oil, wat</sub></span><span class="Normal--Char" style=" font-family: 'HelveticaNeueLT Pro 35 Th', 'Arial';

fitted with a cable strain relief device, located within 5 feet (1.52m)
of motor housing, capable of being attached to the S hook mounted on
the motor housing band clamp.  This will ensure that no potential
damage can occur to any cable connections, due to tension
on the cable.
Underwater power cable disconnect shall be located approximately three feet from
the motor housing.  It is a two piece molded assembly made of thermoplastics,
meeting UL 778 requirements. The ca}</span><span class="Normal--Char" style=" font-family: 'HelveticaNeueLT Pro 35 Th', 'Arial';

underwater pin and socket connector (see Section 1.2 Item J.). 
The body end of the disconnect shall be permanently attached to the
underwater power cable and sealed with an approved compound.  This

to the cable.  The disconnect shall be sealed with an internal
o-ring and by an external Series 300 stainless steel clamp ring, which
can be easily opened. 

Underwater Pin and Socket
Connector (1-5HP)
shall consist of a Series 900 IP68 pin and socket
connector.  It shall be of a 4 pin configuration rated 32 amps
