1 1.0 INTRODUCTION This manual contains information important to the installation, operation and maint enance of your Tonkaflo multi-stage centrifugal pump. Y our Tonkaflo pump has been designed for reliable service in many types of pumping appl ications.
2.0 TONKAFL O SPECIFICA TIONS 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.
2.2 P erformance Specif ications 2.2.1 Pump Performance Table 2.1 Pump Performance Summary * Standard model pumps shown. Higher pressures are available upon request . 2.2.2 All QSV Pumps - IMP OR T ANT! There is no limit on pumping capacity when operating QSV pumps in parallel.
2.3 Mat erials Specif ications Liquid End Wetted Castings: 316 Stainless Steel Pump Shell and Shaft: 316 Stainless Steel Stages: Noryl* O-Ring Seals and Shaft Bearings: Buna-N Rubber Motor Module Powe.
3.0 PUMP INST ALL A TION 3.1 Inspection Y our pump was inspected and test ed at the factory prior to shipment t o 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 immed iately reported t o the carrier.
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 l ife. They are: 1.
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.
3.4.5 Discharge Screen (Strainer) A 30-mesh discharge screen (available as an accessory) located in the d is- 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).
3.5 Pump Priming - IMP OR T ANT! QSV pumps are not designed to be self-priming. W ARNING: THE INLE T PIPING, MO TOR MODULE AND PUMP LIQUID END MUST BE COMPLETELY FILLED WITH LIQUID (PRIMED) BEFORE ST AR T-UP (Figure 3.4, Priming Pump Level). Figure 3.
3.6 Mot or Wiring 3.6.1 Single-Phase Motors - IMP OR T ANT! Single phase three-wire motors require the use of a special controller includ- ed in a separate enclosure with each mot or.
3.6.2 Three-Phase Motors - IMP OR T ANT! BEFORE ST ARTING THREE-PHASE MO TORS 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 d irection, depending on how they are connected t o the power supply.
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.
3.7 Electrical Grounding W ARNING : ELECTRICALLY GROUND THIS UNIT PRIOR TO ST ART-UP . Failure to do so may result in serious injury or death! Verif y there is electrical continuity between the motor module and the junction box using a volt-ohm meter (Figure 2.
4.0 PUMP OPERA TION Review Section 2.0 (Tonkaflo Specif ications) and Section 3.0 (Pump Installation) before operat- ing your pump. 4.1 Priming Prime the pump as noted in Section 3.5 (Pump Priming). 4.2 Operation Operate the pump within its specif ied flow range.
5.0 GENERAL TROUBLESHOOTING This troubleshooting guide can assist you in identifying common operating problems you may experience with your machine. 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 Cent er.
16 REMEDIES QSV pumps are not designed to “l ift” or “pull” fluid from a tank . QSV pumps must be fed with positive pressure [at least 20 psi (1.4 bar)]. This may be accomplished either by having positive head from the tank or incorporating a transfer pump.
17 REMEDIES Verif y 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 inspect ed for possible damage prior to starting.
18 REMEDIES Measure the current draw to verify it is below the trip set- ting. Increase the heater size or adjust the trip setting t o correspond to the S.F . A . indi- cated by the mot or label. QVS pumps are designed to pump water. Consult the fac- tory for l iquids other than water.
19 REMEDIES Conf irm both the pump l iquid end and motor module are f irmly secured t o a rigid structure. QSV pumps must be fed with positive pressure [at least 20 psi (1.4 bar). Check to make sure there are no obstructions, constrictions, high points, or clogged f ilt ers ahead of the pump.
6.0 FIELD MAINTENANCE 6.1 Flow-Cooled Mot or and Liquid End - Tonkaflo Service P olicy W ARNING: FIELD SERVICE OF THE FL OW-C OOLED MO T OR OR LIQUID IS NO T RECOMMENDED . If a liquid end is damaged by running the pump dry, inadequate flow , deadhead ing, cavitation or other reasons, return it with the motor to the fact ory for repair.
To separate the l iquid end from the motor module, simply remove the four bolts joining the two together (Figure 6.8, Liquid End and Motor Module) and carefully pull them apart (Figure 6.10, Liquid End Removal). To rejoin the liquid end to the mot or module, use the following pro- cedure: (Figures 6.
