    2.3AF (208/240V 3 Phase) Pond Aerator Detailed Specifications____


    1.1. Manufacturer shall furnish a surface aeration device that is self contained with integrated float ring

    and capable of pumping water from below the water surface into the air creating a “crown” shape or

    splashing affect and effectively mixing water throughout the lake or pond.

    1.2. Submersed aerator motor with top intake shall push water into the air using an open propeller design. 1.3. Individual water droplets absorb oxygen from the atmosphere and return to the body of water

    transferring oxygen from the air and into the water.

    1.4. Moving water shall mix and agitate the water, spreading oxygenated water throughout the body of


    1.5. Single open propeller design shall allow for greater water flow with a lower likelihood of clogging

    and smaller water droplets to increase total surface area for oxygen transfer.

    1.6. Coated stainless steel cage/propeller guard shall catch large debris and assist in reducing the

    likelihood of clogging while allowing for maximum water flow into the unit.


    2.1. Motor: The motor shall be 2 (2.0) HP, 1750 RPM, 208/240 volt, 3 phase, 60 Hz, oil-cooled,

    continuous duty rated, submersible motor. The rotor shall have a shaft of Series 300 stainless steel,

    be supported by top and bottom ball bearings, dynamically balanced, and have a sacrificial zinc

    anode installed for corrosion protection and salt water compatibility. The stator windings shall be

    dipped and baked with a Class B insulation designed for complete immersion in oil. The assembled

    motor unit (rotor and stator) shall be completely submersed in a no detergent, low weight, turbine oil

    for continuous lubrication of internal seals and ball bearings and for efficient transfer of heat to and

    through the stainless steel unit housing wall. The motor unit shall be sealed with an internal

    mechanical seal and O- ring. The internal mechanical seal shall be a silicon carbide, fully unitized,

    heavy duty mechanical seal. The O-ring shall be molded rubber composite which expands in the

    presence of oil to create a water tight seal. Motor shall be attached to a thermoplastic motor top and

    inside a Series 300 stainless steel housing. No air or water lubricated motors are acceptable. Motor

    shall be serviceable.

    2.2. Motor Housing: The motor housing shall be a canister formed deep drawn and annealed Series 300

    austenitic stainless steel with an additional stainless steel protective ring welded to the bottom of the

    housing for added strength. The motor top shall be engineering grade thermoplastic with brass

    inserts for motor mounting bolts, and molded, threaded power cable connection with brass pins

    molded into the thermoplastic. The motor top shall fit into the motor housing canister with a molded

    rubber composite O-ring creating a water tight seal.

    2.3. Aerator Components: The pond aerator shall have a 3-blade U.V. resistant engineered

    thermoplastic with aluminum insert propeller with each blade on the same plane. A coated series

    300 Austenitic stainless steel cage/propeller guard with 18 vertical bars with 1.5” spacing shall

    surround the propeller to block incoming large debris, add additional strength to the unit, and act as

    the mounting mechanism to the float assembly.

    2.4. Float: The float shall be a U.V. resistant, high density, molded thermoplastic, and of three piece

    construction with protective coated 300 Series stainless steel hardware and brackets. The protective

    motor cage shall attach to the coated stainless steel brackets with 300 Series stainless steel hardware.

    The float shall include three 50’ braided nylon mooring/anchoring ropes.

    2.5. Underwater Power Cable: The power cable shall be type SOOW UL, CSA, and NEC approved

    underwater rated, 4 conductor cable. The power cable shall have 6’ of protective flex sleeving at the

    unit for rodent protection. The power cable shall be available in 50’ 14/4 AWG, 100’ 14/4 AWG,

    150’ 14/4 AWG, 200’ 14/4 AWG, 250’ 12/4 AWG, 300’ 12/4 AWG, and 400’ 10/4 AWG cord

    lengths and gauges. An underwater approved, potted, O-ring sealed quick disconnect shall be

    factory installed on 12 AWG and larger power cables approximately 30” from the motor housing. A

     Rev. 9/29/10 2

    Series 300 stainless steel clamp on strain relief with stainless steel chain and connector shall be

    installed on the power source side of the quick disconnect and attached to the float upon installation

    for protection of the quick disconnect.

    2.6. Fasteners: All fasteners shall be Series 300 stainless steel.


    3.1. Optional Protective Screen: The protective coated, stainless steel bottom screen with 84 vertical

    screening bars with gaps tapered from .875” to .188” to protect the unit and keep debris out shall be

    available as an option for added protection and clog resistance. The protective bottom screen shall

    include 300 Series stainless steel attachment clips and hardware to allow for attaching to the aerator


    3.2. Optional Electrical Control Panel: The electrical control panel shall be UL listed industrial control

    panel per National Electric Code (N.E.C) and be enclosed in a NEMA Type 4x/3r weatherproof,

    non-metallic enclosure. The electrical control panel shall be 208/240V. The electrical control panel

    shall include 3 phase approved, 30ma Rated GFI protection. A 24 hour mechanical timer shall be

    included in the control panel to operate the aerator. A surge protector shall be included in the circuit

    to protect against power surges. The control panel shall include a motor starter with adjustable

    overload and phase monitor. A Hand-Off-Auto switch shall be included on the side of the panel.

    The internal terminal block shall be angled for ease of use with an input terminal for field installed

    interlock. Controller shall include field terminal diagram, electrical schematic, and startup

    procedure on inside door panel.


    4.1. The unit shall be total component tested and approved as a complete assembly. Individual

    component testing is not allowed. The aerating fountain must be tested by ETL, ETL-C, CE, UL, or

    other accredited testing facility.

    4.2. The unit shall be tested as a complete unit and must meet UL (Underwriters Laboratories, Inc.)

    requirements in compliance with Category 778 for Motor-Operated Water Pumps and compliance

    with Category 50 for the Electrical Equipment (control panel).


    5.1. The unit shall include a 3 year manufacture’s repair warranty on all components. Unauthorized

    tampering will void the warranty.


    6.1. The unit shall be a KASCO 2.3AF Model, 2 horsepower manufactured by Kasco Marine, Inc., 800
