The pressures listed above cover normalselections using standard materials. Whenunusual selections are made in order todevelop unusually high shut off pressuresrefer to Section 125, Page 5 for exactmaximum operating heads. If the jobrequirements exceed these figures, pleasecontact the factory for pricing forconstruction capable of handling higherheads.

The shut off thrusts listed are themaximums that the bowls may require. Ifyour selection exceeds the standard motorthrust rating, determine whether the pumpwill be required to run at shut off. If not, theminimum operating capacity should be usedto determine the maximum thrust fromSection 133, Pages 52 thru 60. This canthen be checked against the standard thrustratings of the motors.

As with line shaft pumps, upthrust must beconsidered on submersible pumps. All ofour pumps have momentary upthrust. Thismomentary load can be taken by either thepump upthrust bearing or the motorbearing. These bearing are not designed tohandle continuous upthrust. To differentiatebetween the two, momentary upthrust islimited to a few seconds. Anything over 30seconds must be considered as continuousupthrust and motors fitted for continuousupthrust protection should be used. In orderto avoid operation with continuous upthrustyour selection should be as far to the left ofthe zero (0) thrust point as practical. Shouldthis appear to be a problem contact thefactory to review the application.

Maximum horsepower motor ratings arebased on our 1) standard shaft sizes with416SS shaft and 2) available motordiameters w/ interconnectors for specifiedbowl models. Most bowl models areavailable with higher rated materials andcan be supplied with oversized shaft. If yourapplication exceeds the horsepowerlimitations listed contact the factory forsuggested changes and special pricing.

FOOTNOTES:1 Square D ambient compensated overload relays may also be used. For Square D size 1, 2, or 3, specify form Y59 which designates specialoverload relays, and use same heater number as Furnas: where size 00 or 0 is listed, use size 1. For Cutler Hammer control use G.E. heaters andheater block.2 Innova 45 heater selections apply with the trip current adjustment in the nominal position, where it must be kept.3 General Electric relay trip adjustment should not be set higher than 100% when using these heaters.4Westinghouse Instrument relay ampere setting should never be set higher than listed.5When selecting Heinemann Relay, time delay curve No. 2 must be specified.6 For Westinghouse overload relay, a letter will follow the fast two figures, "A" for starter mounting or "P" for panel mounting, for example FT13A-12 or FT13P-12.7 Use size 1-3/4 Furnas starter with this motor rating.8 Use size 2-1/2 Furnas starter with this motor rating.9 Use size 3-1/2 Furnas starter with this motor rating.s Furnas size 3-1/2 may be used for 60 & 75 HP

Characteristics of submersible motors differ from standard motors and special overload protection is required. if the motor is stalled, the overloadprotector must trip within approximately 10 seconds to protect the motor windings. When using three phase submersible motors, the installer mustprovide special extra-quick trip protectors which are of the ambient compensated type. Ambient compensation is necessary to provide adequatelocked rotor protection at low temperatures, and to avoid nuisance tripping at high temperatures. The tables below list current selection andsettings for several brands. However, with some restrictions, protectors by Arrow-Hart, Delta, Hoagland, Rowan, Siemens-Allis, Telemecanique,and others may be used


SUBMERSIBLE TURBINE PUMPSOVERLOAD PROTECTION AND FUSE REQUIREMENTS

FOR 6" and 8" Franklin Motors





Cooling Flow Requirements6” and 8”Franklin Motors

MINIMUM FLOW VELOCITIESFOR PROPER MOTOR COOLING

As part of the Franklin Electric Co., Inc. submersiblemotor warranty, minimum liquid flow velocities past themotors are required for proper motor cooling. Theseminimum velocities are:

For 6" motors (5 - 30 HP): 1/2 foot per secondFor 8" motors (40 - 100 HP): 1/2 foot per second

The following requirements must be met to validate theFranklin Electric motor warranty:

1. Liquid flow past the motor must be free ofrestriction such as that caused by sand,cave-in or other well deterioration.

2. The following conditions require a flowinducer to duct cooling flow past the motor ifcooling flow rates are otherwise inadequate:

a. Top feeding or cascading wellsb. Large diameter wellsc. Sumps

The table at the right indicates the maximum insidediameter for a well or a flow inducer which will producean acceptable cooling flow velocity. Interpolation forother inside diameters is permissible. Extrapolationbeyond the limits in the table is not permissible.

To minimize head loss through a shroud-type flowinducer, the largest flow inducer diameter consistentwith good motor cooling should be used. Approximatehead losses for flow inducers made of standard pipesizes are shown in the table at the right.

Head losses past smooth well casing will be about thesame. Head losses through “rough” well casing will be about 10% higher. Head losses through “very rough” well casing will be about 25% higher.

FLOW INDUCER FOR MOTOR COOLINGA cooling flow inducer is a device (a shield, or ashroud) which will cause pumped liquid to flow past themotor to assure proper cooling.In a relatively small well, the flow inducer might be abaffle between the bowl assembly and the well casing.In a large well or a sump, the flow inducer might be asleeve (shroud) open at the bottom end which causesthe liquid pumped to flow past the motor.In order to avoid entrapped air or gas and consequentair lock, the flow inducer must not seal air tight. But itmust induce adequate cooling flow past the motor.

IF THE NEED FOR A COOLING FLOWINDUCER IS INDICATED, CONTACT THEFACTORY WITH THE FULLEST POSSIBLEDESCRIPTION OF THE APPLICATION.

SUBMERSIBLE TURBINE PUMPSSUBMERSIBLE CABLE SELECTION & LOSS CHARTS


CABLE SELECTIONS ARE BASED ON 5% VOLTAGE DROP AND 30oC AMBIENT. REDUCE THE MAXIMUM AMPERE VALUES 10% FOREACH 5oC THAT THE AMBIENT EXCEEDS 30oC FOR UP TO 50oC MAXIMUM.

FIND THE INTERSECTION OF THE MOTOR AMPERES AND TOTAL CABLE LENGTH (INCLUDE CABLE FROM WELLHEAD TO THECONTROL): USE THE CABLE SIZE TO THE RIGHT OF THIS POINT. EXAMPLE: 65 AMP, 460V MOTOR; 600 FEET SETTING PLUS 50 FEETTO CONTROLLER. THE CABLE SIZE LINE TO THE RIGHT OF THIS POINT (65 AMPS, 650 FEET ON THE 460V SCALE) IS NUMBER 4CABLE.

THE CABLE LOSS MUST BE ACCOUNTED FOR TO DETERMINE INPUT HP AT THE CONTROL. POWER COST EVALUATION MAYDICTATE THE USE OF LARGE CABLE.



SUBMERSIBLE TURBINE PUMPS2300 Volt Splicing Instruction


1. Train cables in final position and cut to properlength so cable ends will butt squarely.

2. Remove cable jacket from ends to be spliced fordistance equal to C plus D plus one-half the length ofconnector to be used, plus 1/2”. Determine dimensions to be used from the table on the drawingopposite the size of the conductor being spliced.

3. Remove the cable insulation from the ends of eachconductor for a distance of 1/2” plus one-half thelength of the connector.

4. Taper the insulation at each end smoothly for adistance equal to dimension “D” from the table opposite the cable size. Sandpaper may be used tobuff taper to insure a smooth taper so that no voids willremain after the joint is insulated.

5. Taper cable jacket at each end smoothly for adistance equal to dimension “B”. Sandpaper may be used to buff the tapers.

6. Join the conductors with the connector. If soldertype connector is used, protect cable insulation withasbestos roving or cotton tape. Remove burrs.

7. Clean all exposed surfaces to be taped thoroughlywith a knife. Wipe clean with a clean cloth.

8. Wrap successive layers of “Scotch” #23 Tape (or equal) half-lapped to dimension “A” beyond the shoulder of each jacket taper building up the splicesmoothly with equal tension. Apply #23 Tape (orequal) stretching it to reduce it to three-fourths of itsoriginal width to give proper elongation. Build thesplice up equal to dimension “E” over the connector or 3/16” over jacket as shown in Fig. 2.

9. Cover the entire splice with four layers of “Scotch” #22 or #23 Tape half-lapped extending along cablejacket equal to dimension “A” per drawing. Tape should be stretched to reduce its 3/4” width to 5/8” to insure good conformance.

10. Paint entire splice with “Scotchkote”.
