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 main- tenance only. Further information may be obtained by contacting your nearest Tonkaflo distributor or GE. Contact GE at: GE Infrastructure Water &...
TONKAFLO SPECIFICATIONS 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.
Pump Performance 60 Hz Operation (3450 rpm) Capacity gpm (m Series 5 - 21 QS1800V (0.25 - 1.1) 10 - 40 QS2800V (2.3 - 9.1) Standard model pumps shown. Higher pressures are available upon request. 2.2.2 All QSV Pumps - IMPORTANT! There is no limit on pumping capacity when operating QSV pumps in parallel.

For liquids other than water; aque- ous solutions or corrosive solutes, consult your local Tonkaflo distributor or factory.
PUMP INSTALLATION 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.
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: A suitable operating environment. An adequate electrical supply. An adequate flow of cooling water over the motor.
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.
3.4.5 Discharge Screen (Strainer) A 30-mesh discharge screen (available as an accessory) located in the dis- charge 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).
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). Discharge Inlet WARNING: THE PUMP MUST BE SHUT-OFF IMMEDIATELY IF PRIME IS LOST TO AVOID POSSIBLE DAMAGE TO THE INTERNAL PARTS OF THE MOTOR AND LIQUID END.
Motor Wiring 3.6.1 Single-Phase Motors - IMPORTANT! Single phase three-wire motors require the use of a special controller includ- ed 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.
3.6.2 Three-Phase Motors - IMPORTANT! BEFORE STARTING THREE-PHASE MOTORS STEPS Prime pump before applying power to avoid damage to the pump and motor. 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.
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 Measure the current through each of the three legs. Determine the average of the three currents. Determine the difference between the current in each leg and the average of all three legs.
Electrical Grounding WARNING: 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.
PUMP OPERATION Review Section 2.0 (Tonkaflo Specifications) and Section 3.0 (Pump Installation) before operat- ing your pump. Priming Prime the pump as noted in Section 3.5 (Pump Priming). Operation Operate the pump within its specified flow range. Failure to do so may damage the motor or liquid end.
The operator can easily correct may of these problems, however, for those that persist or are not understood you should contact the GE Customer Support Center. Have the following information available when calling the Customer Support...
