Motor shall be of open frame construction with a Series 300 stainless steel shaft and with a serviceable heavy duty ball bearing support system. The rotor shall be
dynamically balanced. The stator Class F insulation, designed for
windings shall oil immersion
be double dipped
and baked with oil shall be of
synthetic food grade continuous lubrication efficient heat transfer
quality, meeting FDA regulations. The oil shall provide of bearings and internal seals and further function as an medium, allowing the motor to operate at 3450 RPM, at
relatively low temperatures. The motor Series 300 stainless steel top plate.
Seals used to protect the motor against water or oil leakage shall be a mechanical, rotating type assembly, composed of silicon carbide and Series 300 stainless steel.
All elastomers shall meet encapsulated and protected
UL 778 requirements.
This assembly shall then be
within a Series 300 stainless steel cartridge assembly.
G. 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, water and cracking. Power cable shall be fitted with a cable strain relief device, located within five feet of motor housing, capable of being attached to the S hooks mounted on the cart framework. 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 four feet from the motor housing. It is a two piece molded assembly made of thermoplastics, meeting UL 778 requirements. One end of this disconnect is permanently attached to the stainless steel motor housing by means of a reinforced braided hose, sealed with a flexible potting compound. The other end is permanently attached to the underwater power cable and sealed with an approved compound to prevent water entry if damage would occur to the cable. This disconnect is sealed with an internal o-ring and by an external Series 300 stainless steel clamp ring, which can be easily opened. This allows removal of the motor housing without the power cable attached for storage or maintenance.
Fasteners and anchor connectors shall be Series 300 stainless steel. . Electrical control panel specifications, see SECTION 3.
Intake screen shall be made of 18 Gauge, Series 300 stainless steel. A stainless
steel handle cleaning as representing
shall be attached to the top end of the screen
350 square inches of open intake area.
