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 afx 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.

The Amprobe is a multi-range, combination
ammeter and voltmeter.
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.
12
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
RXRXRXRX
= 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.

Megger
This instrument is used to measure insulation
MEASURING INSULATION RESISTANCE
resistance to ground. It consists of a crankturned magneto, on the side of the case, and
will give very close readings calibrated directly in ohms. It is cranked at a moderate rate
of speed, approximately 120 rpm, until the
pointer reaches a steady deflection.
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.

3. Reading: Should register some value,
Approx. 200-1000 ohms.
COIL CHECKOUT
What It Means –
Infinity reading indicates coil is open. Zero
reading indicates coil is shorted. In either case,
the coil should be replaced.
A reading of 200-1000 ohms indicates coil is
ok.
