1.0 INTRODUCTION

This manual contains information important to the installation, operation and maintenance
of your Tonkaflomulti-stage centrifugal pump. Your Tonkaflo pump has been designed for
reliable service in many types of pumping applications. Proper installation and normal main­tenance will help ensure extended pump life and prevent costly downtime.

Before installing and operating your Tonkaflo pump, please read these instructions carefully
and keep this manual handy for future reference. This manual is intended for general main­tenance only.

Further information may be obtained by contacting your nearest Tonkaflo distributor or GE.

This manual is not int

ended for repair or overhaul of the Tonkaflo pump liquid ends.

Only the factory and those certified by the Factory Service School are authorized to repair,
service or overhaul Tonkaflo liquid ends.

Your new Tonkaflo multi-stage centrifugal pump is designed for quiet, efficient, vertical oper­ation in environments where noise from a fan-cooled motor is acceptable. A modular design
permits the liquid end to be separated from the motor module for greater serviceability, while
at the same time ensuring precise shaft alignment. The materials and construction of Quiet
Submersible Verticle (QSV) pumps make them suitable for many chemical and pure water
applications.

The Tonkaflo pump’s multi-stage design allows the user to choose a pump model that most
closely matches the desired performance and, thereby, to achieve the highest pumping effi­ciency. Unlike many other pump manufacturers, Tonkaflo will produce pumps to fit your par­ticular applications should a standard model not suit your requirements.

2.0 TONKAFLO SPECIFICATIONS

2.1 Pump Label Nomenclature

All Tonkaflo pumps use the same model number nomenclature to describe the
series name, nominal flow rate, staging and operation of the pump.

The pump label, showing model number, serial number, construction and
performance, is located immediately downstream from the electrical junction box on
the top side of the liquid end shell. The motor label, showing horsepower, voltage, Hz,
rated amp draw, service factor and service factor amps (S.F.A.), is located immediate­ly upstream from the junction box on the top side of the motor module.
Figure 2.1 (Pump Label and Motor Label) shows these locations.

2.2.2 All QSV Pumps - IMPORTANT!

There is no limit on pumping capacity when operating QSV pumps in parallel.
The discharge pressure of your QSV pump may be increased by 100 psig (6.9
barg) by connecting another pump in series ahead of the QSV pump. Care
must be taken, however, so that the inlet pressure to any QSV pump does not
exceed the 100 psig (6.9 barg) maximum inlet pressure rating.

There must be adequate flow through the pump at all times to prevent exces­sive heat build-up.

3.0 PUMP INSTALLATION

3.1 Inspection

Your pump was inspected and tested at the factory prior to shipment to ensure it
meets the requirements of your order. It is suggested the pump be checked upon
receipt for possible damage due to shipping. Any damage should be immediately
reported to the carrier.

3.2 Pump Mounting and Locations

The QSV Series pumps are intended for vertical mounting with the right angle inlet of
the pump down. See Figure 2 for correct orientation. The weight of the pump and
motor must be supported by setting the flat end of the outer housing on a rubber pad
supported by a plate or angle. Attach the pump to the frame work of your system
using ALL brackets included. Refer to Section 8.0 (Dimensional Drawing) for correct
bracket placement.

3.3 Operation Safeguards

Quiet Submersible Vertical (QVS) Series pumps are equipped with NEMA standard
flow-cooled motors, which are cooled by the process fluid. In general, flow-cooled
motors have three requirements for long operational life. They are:

1. A suitable operating environment.

2. An adequate electrical supply.

3. An adequate flow of cooling water over the motor.

Quiet Submersible Vertical (QSV) Series pumps have been engineered to provide a
suitable mechanical operating environment and to provide an adequate flow of cool­ing water over the motor, provided the pump is operated between the maximum and
minimum flow rates specified for each pump series.

W

ARNING: CERTAIN SAFEGUARDS MUST BE IN PLACE TO PREVENT THE

FOLLOWING OPERATING CONDITIONS:

• Flow rate below minimum specified flow rate

• Close discharge valve (deadheaded condition)

• Dry running

• Fluid temperature greater than 90°F (32°C)

• Low voltage

• Imbalanced three-phase power

Safeguards include low-pressure switches, low-flow shutdown, switches, tempera­ture limit switches, quick-trip circuit breakers and properly-sized motor starter
heaters. The three-phase electrical power must exhibit amperage readings in each
leg within ±5% of the average for all three legs (Section 3.6.3, Three-Phase Power
Imbalance). Consult the motor operation manual for additional information.

3.4 Inlet and Discharge -

IMP

ORTANT!

3.4.1 Inlet Piping

• Positive feed pressure is required at all flow points.

• Avoid “high points” and other areas where air may accumulate ahead of
the pump.

• The inlet piping should be at least as large as the inlet port; pipe size
changes should be tapered.

• Sizing pipe to induce 3 psi (0.21 bar) pressure drop or less per 100 feet
(30.5 m) is recommended.

• NE

VER throttle the pump on the inlet side.

• The pump inlet line should be filled and tested with 20 - 100 psi
(1.4 - 1.6 bar) pressure to detect any leaks prior to start-up.

6

3.4.2 Discharge Piping

• Select piping to handle the maximum flow and pressure developed by
the pump.

• Sizing to induce 10 psi (0.70 bar) pressure drop or less per 100 feet
(30.5 m) is recommended.

3.4.3 Piping Connections

The standard QSV Series pump inlet and discharge connections are grooved
for Victaulic clamped-union couplings with gasket. The standard inlet and
discharge connection is 1-1/4-inch Victaulic. Victaulic couplings are available
worldwide. Contact the factory or your local industrial piping wholesaler.

3.4.4 Inlet Line Screen/Filter

This is a precision multi-stage pump with close tolerances to provide maxi­mum efficiency. It is good practice to install a large area 30-mesh or finer
screen, or a cartridge filter in the pump inlet line to collect any foreign objects
or large particles. Size the screen or filter so as to induce a minimal pressure
drop.

W

ARNING: THE PUMP MUST NOT BE OPERATED WITH RESTRICTED SUC-

TION LINE (INLET) FLOW.

Positive gauge pressure must be maintained at the pump inlet (down stream
from the screen or filter). A clogged screen or filter will result in a greater pres­sure drop than a clean screen or filter. To prevent possible pump damage
from low inlet pressure, a low-pressure alarm or shut-off switch should be
located between the screen or filter and the pump. A low-flow shut-off switch
should also be located in the same area.

7

3.4.5 Discharge Screen (Strainer)

A 30-mesh discharge screen (available as an accessory) located in the dis­charge piping will protect your process fluid should the pump be damaged.
The installation of the screen is shown in Figure 3.3 (Discharge Screen
Installation).

3.5 Pump Priming - IMPORTANT!

QSV pumps are not designed to be self-priming.

WARNING: THE INLET PIPING, MOTOR MODULE AND PUMP LIQUID END MUST

BE COMPLETELY FILLED WITH LIQUID (PRIMED) BEFORE START-UP
(Figure 3.4, Priming Pump Level).

3.6 Motor Wiring

3.6.1 Single-Phase Motors - IMPORTANT!

Single phase three-wire motors require the use of a special controller includ­ed in a separate enclosure with each motor. The controller enclosure is not
attached to the motor. Operation of motors without the controller or using
the incorrect controller can result in failure of the motor and voids warranty.

The controller is mounted in a NEMA 4X enclosure and suitable for indoor or
outdoor applications within temperatures of 14°F (-10°C) to 122°F (50°C).

The controller should never be mounted in direct sunlight or high-temperature
locations as this will cause shortened capacitor life and unnecessary tripping
of the overload protector.

The controller enclosure is designed for vertical upright mounting only.
Mounting in other positions will affect its operation.

The controller must be electrically wired to the motor using minimum 8 AWG
for 5 horsepower motors and 10 AWG for 3 horsepower motors.

Figure 3.5

Two Sources of Power to

the Single-Phase Controller

The controller must be supplied with two sources of power. The control circuit
(motor starter coil) must be electrically wired with 110 VAC-50 Hz or 120 VAC­60 Hz voltage. The power circuit must be electrically wired with single-phase
to match the motor label.

10

3.6.2 Three-Phase Motors - IMPORTANT!

BEFORE STARTING THREE-PHASE MOTORS

STEPS

1. Prime pump before applying power to avoid damage to the pump and
motor.

2. Check the direction of rotation.

Three-phase motors can run in either direction, depending on how
they are connected to the power supply. When the three cable leads
are first connected to the power supply, there is a 50% chance that
the motor will run in the proper direction. To make sure the motor
running in the proper direction, carefully follow the next procedure:

Figure 3.6

Changing Motor Rotation

STEPS

A. Start the pump and note the pressure and flow rate developed

at the pump discharge.

B. Stop the pump and interchange any of the two leads (Figure

3.6, Changing Motor Rotation).

C. Start the pump again and re-check the flow rate and pressure.

D. Compare the results observed. The wire connection that

yielded the highest pressure and flow rate is the proper con­nection. Interchange the two leads again only if necessary.

11

3.6.3 Three-Phase Power Imbalance

Current imbalance should not exceed 5% of the average three-phase
current. The current imbalance can be calculated as follows:

STEPS

1. Measure the current through each of the three legs.

2. Determine the average of the three currents.

3. Determine the difference between the current in each leg and the
average of all three legs.

4. Take the difference with the largest value, and divide it by the average
current. Multiply by 100 to obtain the current imbalance percentage.

5. If the current imbalance is greater than 5%, “roll” the leads and re-test
(Figure 3.7, “Rolling” the Leads to Balance Current Draw). If “rolling” the
leads does not correct the problem, the source of the imbalance must
be located and corrected. For more information on current imbal­ance, refer to the motor operation manual.

Figure 3.7

“Rolling” the Leads to

Balance Current Draw

3.6.4 Wire Sizing

For correct power lead sizing from the power source to controls and motor,
refer to the motor installation manual or local electrical codes.

12

3.7 Electrical Grounding

W

ARNING: ELECTRICALLY GROUND THIS UNIT PRIOR TO START-UP.

Failure to do so may result in serious injury or death!

Verify there is electrical continuity between the motor module and the junction box
using a volt-ohm meter (Figure 2.1, Pump and Motor Labels). The junction box must
be grounded to an earth ground following local electrical codes. Grounding lugs are
provided within the junction box for this purpose. Check the continuity of your ground
connection to the motor module using a volt-ohm meter.

The motor module flange may also be directly connected to an earth ground.

3.8 Mot

or Protection - IMPORTANT!

Warranty on the flow-cooled motor is void unless proper quick-trip ambient compen­sated protection is used on all three motor lines. Subtrol may be used on pumps with
Franklin Motors. Refer to the motor installation manual.

13

4.0 PUMP OPERATION

Review Section 2.0 (Tonkaflo Specifications) and Section 3.0 (Pump Installation) before operat­ing your pump.

4.1 Priming

Prime the pump as noted in Section 3.5 (Pump Priming).

4.2 Operation

Operate the pump within its specified flow range. Failure to do so may damage the
motor or liquid end. Refer to the Performance Specifications (Section 2.2) or the per­formance curve supplied with your pump.

CA

UTION: Do not run pump dry or without sufficient heads.

The pump shall not be operated with an inlet pressure less than
20 psi (1.4 bar).

Do not deadhead pump.

The pump shall not be operated below the minimum or above the
maximum capacity specified for your particular model
(Table 2.1, Pump Performance Summary).

Do not exceed 90°F (32°C) operating fluid temperature.

The pump may be flushed with sanitizing water provided no power is
supplied to the motor.

4.3 Restarts -

IMP

ORTANT!

A maximum of 100 starts per day is recommended

Motors should be allowed to run one minute to dissipate heat build-up from starting
current

15

REMEDIES

The pump inlet should be

piped to induce minimal pres-

sure drops through piping

diameter changes, elbows,

instrumentation, etc. QSV

pumps should NEVER be

throttled at the inlet. Check

discharge screen for

obstructions.

Verify no debris is clogging

screen or filter.

Make sure the discharge

valve is open enough to keep

the pump running on the per-

formance curve.

Fluid motion in your inlet pip-

ing may draw air into the

pump if the piping is not

sealed properly. Air bubbles

will be visible in the discharge

line.

POSSIBLE CAUSES

Restrictions in the inlet or

discharge

Inlet strainer/filter plugged

Discharge throttling valve

closed (pump deadheaded)

Air leak in inlet piping

PROBLEM

REMEDIES

Verify the fuses are not

blown, a circuit breaker has

not tripped (also check the

breaker for controls), and the

heaters are not overloaded.

The wiring, heater switches

and starter must be inspected

for possible damage prior to

starting.

Make sure the motor is wired

across the proper voltage.

The required voltage is indi-

cated on the motor label.

With the circuit de-energized,

check for continuity using an

ohmmeter.

Confirm the circuit is wired for

single-phase or three-phase

and the motor is grounded.

Check safety shut-off circuitry

to make sure the necessary

circuit by-passes are in place

to start the motor.

Check single-phase motor

controller and verify that it is

in working order. See detailed

label inside controller box.

Check the amp draw through
each leg leading to the motor
using an ammeter. The read-

ings should not exceed the

maximum amps (S.F.A.) indi-

cated on the motor label.

POSSIBLE CAUSES

Blown fuse, tripped circuit

breaker or overloaded

Line voltage connection dif-

ferent from motor voltage

Bad connection

Motor wired improperly

Shut-off controls disabling

Motor exceeding rated amp

draw

PROBLEM

Motor does not run

Motor runs, then stops

TROUBLESHOOTING GUIDE

18

REMEDIES

Measure the current draw to

verify it is below the trip set-

ting. Increase the heater size

or adjust the trip setting to

correspond to the S.F.A. indi-

cated by the motor label.

QVS pumps are designed to

pump water. Consult the fac-

tory for liquids other than

water.

With the pump filled with the

process fluid, use a megohm
meter to measure the resist-

ance between each motor

lead and ground first at low

voltage, then at a potential

between 500 and 1000V if the

low-voltage test indicates an

open circuit. Consult the

motor installation and main-

tenance manual for accept-

able values.

With the circuit de-energized,

check for continuity using an

ohmmeter.

Confirm the circuit is wired for

single-phase or three-phase

power and the motor is

grounded.

Make sure the three legs of

your three-phase power are

balanced within ±5% of each

other.

POSSIBLE CAUSES

Motor starter heater size

too small

Specify gravity of liquid or

viscosity greater than
