Motor Cooling, Temperature and Time Ratings

All 4 inch CentriPro motors may be operated continuously in water up to 86º F. Optimum service life will be attained by maintaining a minimum

ow rate past the motor of .25 feet per

second. Use a Flow Sleeve if velocity is below the .25'/sec, if the well is top feeding or when the pump is used in a large body of water or large tank.

Six (6) inch canned design motors from 5 – 40 HP will operate in water up to 95º F (35º C), without any de-rating of

horsepower, with a minimum ow rate of

.5 ft./sec. past the motor. 6" – 50 HP and all 8" – 10" motors can operate in 77º F (25º C) water with .5'/sec velocity past the motor.

One way to make a ow sleeve is to install a well seal

above the pump discharge and slip a piece of casing

over the pump and afx it to the well seal. Drill three

holes at 120º intervals on the lower section of the casing and insert (3) screws and nuts through the casing, just touching the motor. Tighten the nuts out against the casing. Insure that the screws do not protrude out too far as you don’t want them catching on well joints.

FLOW SLEEVE

TYPICAL SYSTEM

Pump Cooling and Lubrication

In addition to motor cooling, another reason to

maintain minimum ow rates is pump lubrication. All

manufacturers’, either on curves or in selection charts,

show minimum ows. This insures that rotating pump

parts are properly lubricated to prolong service life and reduce friction. A dead headed pump will super heat water very quickly, and hot water has no lubricity.

TROUBLESHOOTING

The Amprobe is a multi-range, combination ammeter and voltmeter.

Voltmeter Scales: 150 Volts 600 Volts Ammeter Scales: 5 Amps 40 Amps

AMPROBE/OHMMETER INSTRUCTIONS

15 Amps 100 Amps

1. When used as an ammeter, the tongs are placed around the wire being measured with the rotary scale on the 100 amp range. Then rotate the scale back to the smaller ranges until an exact reading is indicated.

2. When used as a voltmeter, the two leads are clipped into the bottom of the instrument with the rotary scale on the 600 volt range. If the reading is less than 150 volts, rotate the scale to the 150 volt range to get a more exact reading.

The Ohmmeter is used for measuring the electrical resistance of a wire circuit. The unit of measurement is called an Ohm.

1. The knob at the bottom of the Ohmmeter is adjustable through six ranges: RX1 = R x 1 RX10 = R x 10 RX RX RX RX

= R x 100

100

= R x 1,000

1000

= R x 10,000

10K

= R x 100,000

100K

If your ohmmeter

is digital readout type, refer to the

instructions that

came with it.

2. The round center knob is for the purpose of adjusting the instrument to zero (0) after clipping the two ohmmeter leads together. This must be done every time the range

selection is changed.

AMPROBE/OHMMETER INSTRUCTIONS

CAUTION

Use Ohmmeter only with power off.

1. If the ohm value is normal, the motor

windings are not grounded and the cable insulation is not damaged.

2. If the ohm value is below normal, either the

windings are grounded or the cable insulation is damaged. Check the cable at the well seal as the insulation is sometimes damaged by being pinched.

WARNING!

Open master breaker and disconnect all leads from starter to avoid damage to meter or electric shock hazard. Connect the ohmmeter leads as shown above.

¹ As part of Faradyne Motors' continual improvement process, two waves

of improvements have been made to CentriPro motors. Generation I motors are any motor with a date code prior to April 2011. Information on Generation I motors can be found in the Motor and Installation Manual on Goulds.com. Generation II (2011) motor are motors with dates codes between April 2011 and November 2015. Generation II (2015) motors are motors with dates codes after Novmeber 2015. CentriPro motor date

codes are 12 characters long, the rst character represents the month and the fourth and fth character represent the year. For example, a date code

beginning with "L _ _ 15..." would be a Generation II (2015) motor.

AQUAVAR SOLO WIRE SIZING

To size wire, the voltage drop of each wire segment must be used and the total must not exceed 100%. Example: a 1.5 HP motor, 100' from Service Entrance to Controller (1Ø wire) and 500' from Controller to Motor (3Ø wire).

• Service Entrance to Controller = 100' of # 10 (100/455) = 22 % (455' from 230V 1Ø chart)

• Controller to Motor = 500' of # 12 (500/709) = 71 % (709' from the 3Ø chart)

• 71% + 22% = 93 %; See Balanced Flow Bulletin or IM182 for more info.

1. To check: Shut off power supply and drain

system to “0” pressure.

2. Air pre-charge in tank should be 2 psi less than the cut-in pressure of the pressure switch.

Example: If pressure switch setting is 30-50 psi, tank should be pre-charged with 28 lbs. air.

3. If water at valve, replace tank.

RULE OF THUMB

Improper tank sizing may cause motor damage. ½ to 1½ HP pumps – Tank draw down

should be equal to the pump capacity in GPM or greater.

Example: ¾ HP pump; capacity 12 GPM; pressure switch setting 30/50 PSI; correct tank – V140.

2 HP and larger pumps – tank drawdown should be double the

3. Disconnect motor cord from pressure switch

when used.

4. Remove casing bolts. If pump is mounted

on top of tank, remove bolt holding motor adapter to mounting pad.

5. Disconnect tubing between casing or

pressure control valve and pressure switch.

6. Remove motor, motor adapter casing, and

rotating element. Casing remains attached to piping.

7. Remove guide vane seal ring and diaphragm

gasket ring.

8. Remove guide vane from motor adapter (via

4 bolts or may be snap in type).

9. Remove motor end cover. Insert 7⁄16" open

end wrench under switch mechanism or

behind overload protector onto ats on

motor shaft.

While holding the shaft against rotating, turn the impeller counterclockwise. The impeller should turn completely off the shaft in this manner.

10. Using two screwdrivers, pry out holding

collar of mechanical seal assembly.

11. Motor adapter can be unbolted from the

motor (for motor replacement).

JET PUMP DISASSEMBLY

Jet Pump Reassembly . . .

1. Be sure that recess for seal seat and surface

where guide vane mounts on motor adapter are entirely free of all scale and dirt.

2. Clean motor shaft.

JET PUMPS

3. Apply lm of light oil, such as vegetable oil,

to the recess of the motor adapter and the neoprene bushing before installing the new

seal seat. This is a tight t, but it must go in

all the way evenly, or a leak will result. Do not mar lapped face of this seal. The slightest scar or particle of dirt will cause a leak.

4. Bolt motor adapter to motor, making sure the

motor shaft does not dislocate the stationary seal member.

5. Assemble rotating member of seal on motor

shaft. Rotating seal face must t snugly

against lapped seal face of stationary member in casing cover. This is accomplished by pushing with a piece of tube against back end of neoprene washer after oiling sleeve and shaft. Be sure rotating seal face does not drop out of holding collar while sliding the rotating members of the seal on the shaft. Also, take extra care that the rotating seal face is not marred during handling.

6. While holding the shaft against rotating, screw

impeller on shaft by hand until tight against shoulder of motor shaft.

7. Replace guide vane, making sure that bore

of guide vane does not bind impeller hub. If screws used, tighten alternately and evenly. Check by turning the motor shaft. If binding occurs, loosen screws, readjust guide vane until impeller hub turns freely, then tighten screws as before. Some jets have snap-in guide vane.

8. Replace diaphragm gasket with opening in

the upper position.

9. Replace guide vane seal ring on guide vane

hub.

10. Make sure all gasket surfaces are clean.

Replace pump casing.

11. Tighten casing bolts alternately and evenly.

12. After reassembling pump, check to be sure

impeller rotates freely.

13. Reconnect tube between pressure switch

and casing cover or control valve.

14. Close all drain openings, using pipe joint

compound or teon tape on threads of

plugs.

15. Prime according to Priming Instructions.

A vacuum gauge indicates total suction lift (vertical lift + friction loss = total lift) in inches of mercury. 1" on the gauge = 1.13 ft. of total suction lift (based on pump located at sea level).

RULE OF THUMB

Practical suction lift at sea level is 25 ft. Deduct 1 ft. of suction lift for each 1,000 ft. of elevation above sea level.

Shallow Well System

CHECKING SUCTION LIFT

Install vacuum gauge in shallow well adapter. See opposite page. When pump is running, the gauge will show no vacuum if the end of suction pipe is not submerged or there is a suction leak. If the gauge shows a very high vacuum (22 inches or more), this indicates that the end of suction pipe is buried in mud, the foot valve or check valve is stuck closed or the suction lift exceeds capability of pump.

High Vacuum (22 inches or more)

• Suction pipe end buried in mud

• Foot valve or check valve stuck closed

• Suction lift exceeds capability of the pump

Low Vacuum (or 0 vacuum)

• Suction pipe not submerged

• Suction leak

Compound Vacuum Pressure Gauge

This gauge will show the pressure or vacuum at any position in a pump or system where it is installed.

A reading of 20" on a vacuum gauge placed on the suction side of the pump would tell you that you have a vacuum or suction lift of 22.6 ft.

20" x 1.13' = 22.6 ft.

When pump is rst started or under maximum ow condition, pressure control should

be immediately adjusted to the pressure corresponding to H.P. and jet assembly used. See rating tables in catalog for proper pressure setting.

1. Turn left to reduce pressure.

2. Turn right to increase pressure.

RULE OF THUMB

If pressure control valve is set too high, the air volume control will not function.

If pressure control valve is set too low, the pump may not shut off.

PRESSURE CONTROL VALVES

To Adjust Pressure Control Valve:

1. Close pressure control valve.

2. Open faucet in house.

3. Turn pump on.

4. As pump picks up its prime, the pressure will

begin to rise on the gauge.

5. Turn adjusting screw to set pressure control

valve to pressure recommended in catalog.

Correct rotation is a must on all 3Ø installations. Rotation can be checked by one of these three ways:

Visual 1

1. Connect 3 motor leads to starter, run unit at

open discharge.

2. Switch any 2 leads and again run unit at

open discharge.

3. Largest quantity of water indicates correct

rotation.

Visual 2

1. Remove water end from meter. Run motor

and observe rotation

Pressure

1. Connect 3 motor leads to starter. Run unit

against closed discharge, take maximum pressure reading.

2. Switch any 2 leads and again run unit

against closed discharge. Take maximum pressure reading.

3. Highest pressure reading indicates correct

rotation.

Prolonged reverse rotation operation can cause pump/motor damage.

THREE PHASE UNBALANCE

Current readings in amps should be checked on each leg using the three possible hookups.

CAUTION

To prevent changing motor rotation, the motor leads should be reordered in the same direction, see example on page 53.

RULE OF THUMB

If the unbalance moves with the motor leads the unbalance is caused by the motor, wet splice, or damaged cable. If the unbalance remains with the terminals the unbalance is in the power supply.

Calculate percentage of current unbalance for all three hookups.

Example:

Hook Up 1 Hook Up 2 Hook Up 3

T1= 51 Amps T3= 50 Amps T2= 50 Amps T2= 46 Amps T1= 48 Amps T3= 49 Amps T3= 53 Amps T2= 52 Amps T1= 51 Amps

Add up all three readings for hook up number 1. T1 = 51 Amps

T2 = 46 Amps +T3 = 53 Amps

Total 150 Amps

Divide the total by three to obtain the average.

50 Amps = Average

3 150 Amps Calculate the greatest amp difference from the average. Could be greater than average.

50 Amps

-46 Amps

4 Amps

Divide this difference by the average to obtain the percentage of unbalance.

.08 or 8%

50 4.00 Amps

Hook Up #1 = 8% Hook Up #2 = 4%

Hook Up #3 = 2% Always use hook up with lowest % current unbalance. Loads on a transformer bank vary. Readings should be taken at peak load period.

What It Means –

1. Hook ups below 5% = system balanced.

2. Hook ups not below 5% – if the unbalance moves with

the motor leads the unbalance is caused by the motor, wet splice, or damaged cable. Check the motor on pages 44-45. If the unbalance remains with the terminals the unbalance is in the power supply – contact power company.

THREE PHASE UNBALANCE

A full 3Ø supply is recommended for all 3Ø motors, consisting of three individual transformers or one 3Ø transformer. “Open” delta or wye connections using only two transformers can be used, but are more likely to cause problems from current unbalance.

Transformer ratings should be no smaller than listed in the table for supply power to the motor alone.

• Minimum Speed of 30 Hz – the incoming pressure is 20 PSI or

more below the desired pressure, if pumping from a tank or if drawing a suction lift.

• Ramp Speed – Slow - Low ow; Medium - Medium ow; Fast

- High ow

S-Drive Quick Start Up Guide

Step 1: Mount drive on secure wall or support beam using 4 screws.

Ensure drive is well ventilated. Leave at least 8” of free space around the controller for cooling. Plug conduit holes not used.

Step 2: Measure site voltage phase-phase and phase-ground; verify

incoming voltage is 1Ø or 3Ø 230V, or 3Ø 460V. make sure all phase-ground voltages are equal. Models SPD2XXXX(F) require 230V input voltage. Models SPD4XXXX(F) require 460V input voltage.

Step 3: Provide a dedicated fused disconnect (item #2 above) or

circuit breaker rated for drives input amps. No other equipment should be used for this disconnect. Use fast acting class T fuses.

Step 4: Connect wire from input power supply to L1, L2, L3 and

GND. NOTE: For single phase supply power, wire to L1 and L3 and adjust overload switches for 50% of drive current rating. Ensure you have a solid ground from the building or site. Ensure the ground is continuous between the service entrance and the controller. Ensure there is at least 8” between the input wires and any other wires.

Step 5: Ensure you have a three phase motor. Connect motor leads

to T1/U, T2/V, T3/W and GND. Ensure the ground is continuous between the controller and the motor. For CentriPro motors, connecting T1/U to Red, T2/V to Black and T3/W to Yellow will give the correct rotation. To change rotation, swap any two motor leads T1/U, T2/V or T3/W. Ensure there is at least 8” between the output wires and any other wires.

Step 6: Plumb pressure transducer in straight piece of pipe down-

stream of last check valve in system. Do not install the pressure transducer or pressure tank where freezing can occur. If pressure transducer is placed in grounded metal piping, disconnect the drain wire in the pressure transducer cable from the controller chassis.

Step 7: Pre-charge bladder tank to 10-15 PSI below your system

pressure. Tank capacity should be at least 20% volume of maximum pump GPM.

Step 8: Set the Motor Overload Setting Switches. Choose a setting

that is equal to or less than the motor’s SFA rating.

Step 9: Factory pressure setting is 50 PSI when used with a 300PSI

transducer. Press and hold INC or DEC button to adjust pressure while pump is running. Ensure drive goes into stand-by mode (solid green light/pump off) to save pressure setting.

NOTE: Do not connect power to CONTROL TERMINALS. Connect

only non-powered switch contacts to these terminals.
