Step 2 of 2. Pump Selection Chart

The Pump Wizard Results screen shows a list of pumps that will operate within your operating parameters, as well as a chart displaying the performance curves of each pump. To get more information, click on the appropriate color code in the legend, and a Pump Booklet will be displayed. The pump will also be added to Recently Viewed Pumps.

The Pump Selection Chart allows you to select the pump that provides the closest flow and boost for the application that you have. The Pump Wizard will select the smallest pump that will provide the required boost at the specified flow. If there is a pump that is within 5% below the required boost, the Pump Wizard will show you that as well. If the boost required is larger than a single Tonkaflo® Pump can provide, contact GE Water at 1-886-GEWATER.

The operating parameter that you have entered is shown by the red cross , and the different pumps are color coded for reference in the legend. The black diamond on the curve is the best efficiency point for each pump.

Performance Curve

Pump Booklet Tab #2

The pump curve shows all of the different pump models that are available within the chosen series. The header shows whether the pump has Noryl® or stainless steel pump stages, the pump series number, the expected operation Hz, and the RPM of the motor.

The SS1832 pump curve is shown below. The data is a representation of performance while pumping water (or fluids with a specific gravity of 1.0 and a viscosity of 1centipoise).

SS1832 Pump CurveThe performance curve includes four types of data in graphical form. These include:

1. Pump Performance
2. Efficiency
3. Brake Horse Power
4. Net Positive Suction Head Required

1. Pump Performance is a function of flow and pressure. It is preceded by a model number such as 1832. The performance curve represents typical performance given the motor selections included in the pump and motor packages. DO NOT operate at a flow point which is not on the performance curve.

2. Efficiency is a function of flow. The efficiency of a pump is a tested value that correlates the motor horsepower going in to the pump versus the hydraulic horsepower created by the pump at the discharge. The higher the value the more economically the pump will operate. The efficiency is flow dependent and impeller design dependent. The same efficiency curve is used within a model series no matter the number of stages in the pump. This curve is then read at a given flow rate and indicated on the axis at the top right of the performance curve. Example: the 1800 series pumps operate at their best efficiency point (BEP) at 15 GPM with an efficiency of approximately 58%.

3. Brake Horsepower (bhp) is a function of flow, pressure, and efficiency. It is preceded by a horsepower rating such as 5 HP. The bhp curves show the horsepower required to create a given flow and pressure assuming the efficiency of the pump at that flow rate. For example: on the performance curve above, at 8 GPM it will take 5 hp to create a differential pressure of 450 psi. This does not mean that a pump model exists at that point. It does identify that any pump curve below that line will operate using that motor size. For example: the 1832 pump can use a 5 hp motor safely up to 9 gpm without overworking the motor. Beyond that point a 7.5 hp motor will provide the best performance and will not require the service factor of the motor. The theoretical equation for bhp is:

bhp =

Flow (GPM) X Head (in Feet) X sp. gr.
3960 X Pump Efficiency ( 0.xx)


4. Net Positive Suction Head Required
(NPSHR) is a function of flow. The NPSHR of a pump is the amount of head required by the pump to operate without being damaged due to cavitation. The value is measured in absolute terms, not as a gauge value. The same NPSHR curve is used within a model series no matter the number of stages in the pump. This value can be determined by identifying the desired flow rate of the pump and drawing a line vertically to the NPSHR curve and then horizontally to the vertical axis on the lower right of the performance curve. Example: The SS1800 series pumps at 10 gpm of flow will require 10 feet of head. The calculation below assumes typical atmospheric pressure head of 32 feet, typical frictional pipe losses, and vapor pressures.

NPSHA >= NPSHR
NPSHA = Atmospheric Head + Static Head - Frictional Losses - Vapor Pressure
When source of liquid (feed) is above the pump:
NPSHA = Atmospheric Head (32) + Static Head (10) - Frictional Losses (2.0) - Vapor Pressure (1.0) = 39 Feet
When source of liquid (feed) is below the pump:
NPSHA = Atmospheric Head (32.0) + Static Head (-10.0) - Frictional Losses (3.0) - Vapor Pressure (1.0) = 18 Feet

Flow

Tonkaflo® Pumps are designed to operate within a fixed range of flows (see list below). Operating outside of that range can cause damage to the pump. Running a pump with either too much or too little flow can damage the internal components of the pump. If this operation occurs too often the pump may fail.

In this software, flow is measured in GPM (Gallons per Minute) for English units and in M³/H (Cubic Meters per Hour) for Metric units. Units can be changed in the Preferences section.

Boost (Pressure/Head)

Actual boost may differ from the parameters input. Operation data reflects the input flowrate and is calculated from the pump curves for the pump selected. The pumps displayed by the Pump Wizard will be the closest to the operating request, without being more than 5% below the requested parameter.

Tonkaflo® Pumps are designed to operate within a fixed range of flows. When the pumps are operating within the specified range, they will provide a boost. As the flow changes, so does the boost.

In this program, the boost can be displayed in Head or in Pressure. Pressure is measured in PSI (English units) and in Bar (Metric units), head is measured in feet (English units) and in meters (Metric units). Units can be changed in the Preferences section.

Pressure is a measure of the energy of the water due to its speed. Head is a measure of the height of a column of water that could be created if the fluid were to flow directly up.

Note that there is no 1000 series for the 50 Hz pumps.

Note that the boost provided is a direct result of the flow into the pump. If the required flow or pressure is not available in a standard pump, please Contact GE Water.

Note that the boost listed is for water with a viscosity of 1 cp. and a specific gravity of 1. If operating conditions are different, please Contact GE Water.

Temperature


Temperature is an important factor in choosing the correct pump for an application. If the temperature is too high, the pump can be damaged. Pumps that are rated for higher temperature are typically more expensive.

The SS family of pumps have Noryl stages internally. The Noryl stages are the most temperature sensitive part of the pump for these families. Noryl starts to deform at temperatures above 125°F.

The AS pumps have 304 stainless steel stages. The stainless steel stages are not as temperature sensitive, but the elastomers that are used in the pump begin to have problems at temperatures above 200°F.

Fluid


Tonkaflo® pumps are designed for operation on pure water. Pure water is defined as water with a specific gravity of 1.0 and a viscosity of 1.0 cp.

Fluids other than water change the amount of power required to operate the pump, and the thrust that the pump puts on the bearings. Contact GE Water if you have any questions about the operation of a Tonkaflo® pump.

Motor And Coupling Options


Each Tonkaflo® pump can have a variety of different motors used with it, and in many cases the bearing frame that couples the pump to the motor can change as well.

In order to change the type of motor or the type of bearing frame used (if available), click on the drop down box for the liquid end that you have selected, and a list of the available standard options that the pump can use will be displayed.

The description that is listed shows the coupling type, the motor horsepower, phase and enclosure type and NEMA size, the service factor of the motor and the price for that option.

See Motors for more information about motors in general.
See Bearing Frame/Coupling for more information about bearing frames in general.

Motors


Tonkaflo® Pumps use Marathon brand air-cooled electric motors as a standard. The quality of Marathon motors is excellent. Other motor brands are available upon request.

There is some specific information that is important to know when selecting a motor:

• Frequency (Cycles per Second) or Hertz (Hz): This describes the frequency of the alternating current as a power generator provides it. In the USA and in Canada the power is 60 Hz. In much of Europe, the power is 50 Hz. This is one of the defining areas of the motor, since the performance of the pump is dependent on this.

• Phase (1 or 3): The motors that Tonkaflo® pumps use are either single or three-phase motors. Most residential power is single-phase, while most heavy industrial power is three-phase. A motor will not operate if it is not set up for the appropriate power source, and the wrong power can damage the motor.

• RPM: This is the speed of the motor shaft, and therefore also the speed that the pump shaft spins. Tonkaflo® pumps use 60 Hz motors that are nominally 3550 RPM, and 50 Hz motors that are nominally 2950 RPM.

• Voltage (VAC): Different areas use different voltages. Even areas that have the same frequency can use different voltages. For example, in the USA, single phase power can be either 110 VAC or 220 VAC. It is important to make certain that the motor is rated for the correct voltage, or damage can be done to the motor. The standard for Tonkaflo® pumps is listed below, but non-standard voltages are available.

  Single Phase Motors Three Phase Motors
50 Hz Motors 110/220 VAC 190/380 VAC
60 Hz Motors 110/220 VAC 208-230/460 VAC

• Horsepower (HP): Horsepower defines how much work a motor can do. As the flow or the pressure is increased, the amount of work required to achieve that flow and pressure increases. A motor will always run at a specific frequency (defined above). If the motor is large enough to operate the pump correctly at that speed, then the pump will run correctly. If it is too large, then the pump will still operate, but the efficiency will be less. If the motor is too small, it will run hot, which may cause damage to it.

• Service Factor (SF): The service factor defines the safety margin that the motor has built into it. If a motor has a SF of 1.15, then the motor can run intermittently at 15% higher than the rated HP before being damaged. There are other things that cause the motor to use SF. One is ambient temperature. Motors are rated to run at 90°F (40°C), and if they operate at a higher temperature, they can be damaged. This service factor is very critical in humid environments. In most cases, Tonkaflo® pump/motor combinations do not rely on the service factor of the motor.

• Enclosure Type: Motors are often classified by their NEMA-Enclosure type. Tonkaflo® pumps offer several standard types:

TEFC: Totally Enclosed, Fan Cooled is the most common motor. As the name suggests, it is totally enclosed and cooled by a fan. It has a higher efficiency (on average) than an ODP motor.

ODP: Open (or Ordinary) Drip-Proof is a motor that relies on the environment to cool it. It is slightly shorter than either the TEFC or the P-Eff motors because it does not have a fan.

• NEMA Frame Size: Motors are all classified by their NEMA Frame size. This number defines all of the dimensions of the motor, except the total length of the motor and the placement of the electrical junction box. As the numbers get larger, so do the motors. The frame size determines the bearing frame that is required to mount the motor to the pump. The frame size also indicates whether or not there is a C-face kit attached to the motor.

A complete list of the frames sizes and the motor configurations is available from the motor manufacturers.

A C-face kit allows a motor to be close-coupled to a bearing frame without mounting the pump and motor on a bedplate.

Bearing Frame/Coupling


Tonkaflo® pumps use a bearing frame to take the thrust off of the motor bearings and discharge it into the frame of the motor or a bedplate (depending on the size and style of the pump). The amount of thrust created by a small pump is small enough that the bearings in the motor can take the thrust and not be damaged. As the boost pressure or flow rate increases, the amount of thrust increases. As the thrust increases, the motor bearings would be increasingly damaged by the application of that thrust. The Tonkaflo® pumps are designed to maximize the lifetime of the pumps and motors.

There are several different ways for motors to be coupled to pumps. They can be coupled, close coupled or direct coupled.

Direct-Coupled: The pump is built directly onto the motor without a bearing frame. In some cases an adapter is used to fit the pump to the motor.

Close-Coupled: The pump is built onto a bearing frame. The bearing frame is then coupled to the motor with a flexible coupling. The motor must have a C-face kit attached so that it can mount to the pump. The advantage is that manual alignment of the pump and motor is not required with close coupling.

Coupled: Coupled pumps require mounting the pump and motor to a common bedplate with a flexible coupling in between. The alignment of coupled pumps can be a time consuming process, even for experienced pump installers. The advantage is the wide range of motors that can be used.

Commonly used bearing frames are listed below:

X: This is actually an adapter more than a bearing frame. The pumps that use this adapter are all direct-coupled, which means that the X adapter mounts the pump directly on the motor without a flexible coupling in between. These pumps cannot be removed from the motors. This adapter mounts to motors that have a NEMA 56J frame.

XB/XC: This is another adapter, replacing the G and D bearing frames on 500, 1000, and 1800 series pumps. This adapter mounts to motors that use a 182/184 TC frame or a 213/215 TC frame. These pumps are direct-coupled.

AZ: This bearing frame is used to mount 56C frame motors to pumps. These pumps are close-coupled.

G: This bearing frame is used to mount motors with a 182/184 TC frame. These pumps are close-coupled.

D: This bearing frame is used to mount motors with a 213/215 TC or a 254/256 TC frame. These pumps are close-coupled.

K: This bearing frame has several different sizes, depending on the motor that is being mounted to the pump. These pumps are close-coupled.

KA: 213/215 TC motors

KB: 254/256 TC motors

KC: 284/286 TSC motors

KE: 324/326 TSC, 364/365 TSC motors

KF: 404/405 TSC motors

E: This bearing frame is the only one that must be mounted to a bedplate. It can be used in place of any K bearing frame, and the motor does not need a C-face kit. These pumps are coupled, and must be aligned. This bearing frame is no longer our standard offering. We can supply pumps with out motors with E-bearing frames on special request. We can also repair E bearing frame motors.

GM/DM: These are bearing frames for metric motors. Contact GE Water for more information.

Elastomers


Elastomers are the flexible, sealing components of the pump. Tonkaflo® pumps offer Buna-N elastomers as standard. The Elastomer Package allows the user to substitute other elastomers into the pump liquid end. There are three elastomer packages available. These include the standard package with Buna-N elastomers, the EPDM package, and the Viton package.

The Buna-N is acceptable for water applications. The EPDM package is commonly applied when pumping caustics or when the pH exceeds a level of 8. The Viton® package is applied when pumping acids, solvents, or when the pH is less than 6. Any time the chemical compatibility of the elastomers is in question, call GE Water at 1-866-GEWATER.

Standard SS Pumps are constructed of 316 stainless steel, Noryl® plastic interals with Buna-N elastomers.

Standard AS Pumps are constructed of 304 stainless steel, 304 stainless steel internals with Buna-N elastomers.

  Standard EPDM Package Viton Package
Mechanical Seals Buna-N EPDM Viton
Shell and Seal Holder O-Rings Buna-N EPDM Viton
Internal Stage Seals and Shaft Bearings Buna-N Teflon / EPDM** Viton***

In addition the 500 and 1800 series pumps utilize Phenolic/Buna wear rings which can be substituted with a Teflon composite.

* Noryl is a registered trademark of G.E. Plastics.
** 4 inch pumps use Teflon, 6 inch pumps use EPDM
*** Teflon may be used on some models only at GE’s discretion

High Pressure Construction


Standard pumps are designed for inlet pressures not exceeding 200 psig and total discharge pressures of up to 750 psig. The Inlet Pressure option allows the user to select a pump construction that will provide the longest seal life in applications with higher inlet pressure. This option also includes a modification to the pump case (shell) to increase the total discharge pressure capability. The total discharge pressure rating is dependent upon the inlet seal pressure package chosen and is automatically supplied.

Select one of the seal packages to fit the inlet pressure requirements in your system.
  Pump Inlet Pressure Total Discharge Pressure
Standard Mechanical Seal <= 200 psi <= 750 psi
High Pressure Mechanical Seal <= 400 psi <= 1000 psi
Balanced Mechanical Seal <= 600 psi <= 1000 psi

Destaging


Destaging is used to reduce the boost pressure of the pump in order to achieve a required pressure without the need for throttling valves or variable frequency drives. Sometimes it may also make sense to destage a pump if future needs require more pressure.

The destaging option involves the removal of impellers from the pump discharge end. In all SS Series pumps, the diffusers are left in the pump with the shaft bearings removed. In all AS Series pumps, excluding the AS40000, the diffusers are left in the pump with the shaft bearings and stage seals removed. The AS40000 has sleeves that replace the diffusers.

The impellers can be added back in rather than purchasing a new pump if required in the future. In order to calculate the produced pressure in a destaged pump, apply a linear extrapolation to the published pump models by determining the boost per stage at your flow rate. If there are more questions, please Contact GE Water.

Adapters


Tonkaflo® pumps come standard with Victaulic connections.

There are standard adapters that can be used to adapt the inlet and discharge connections to other size connections or other style connections. There are some limitations to the adapters available. These limitations are due to the minimum flow requirements for the different size pumps. All of the adapters that are available to the different pumps will be presented through the Options Worksheet. Only those adapters that fit a selected pump may be selected.
