2 Safety 2 Safety All the information contained in this section refers to hazardous situations. DANGER 2.1 Key to safety symbols/markings Table 2: Definition of safety symbols/markings Symbol Description DANGER DANGER This signal word indicates a high-risk hazard which, if not avoided, will result in death or serious injury.
2 Safety ▪ Observe the maximum flow rates indicated in the data sheet or product literature (to prevent overheating, mechanical seal damage, cavitation damage, bearing damage, etc). ▪ Do not throttle the flow rate on the suction side of the pump (to prevent cavitation damage).
2 Safety ▪ Eliminate all electrical hazards. (In this respect refer to the applicable national safety regulations and/or regulations issued by the local energy supply companies.) 2.8 Safety information for maintenance, inspection and installation work ▪ Modifications or alterations of the pump are only permitted with the manufacturer's prior consent.
On transfer of goods, check each packaging unit for damage. In the event of in-transit damage, assess the exact damage, document it and notify KSB or the supplying dealer (as applicable) and the insurer about the damage in writing immediately.
3 Transport/Temporary Storage/Disposal 3.5 Disposal WARNING Fluids and supplies posing a health hazard and/or hot fluids and supplies Hazard to persons and the environment! ▷ Collect and properly dispose of flushing medium and any residues of the fluid handled. ▷ Wear safety clothing and a protective mask, if required. ▷...
4 Description of the Pump (Set) 4 Description of the Pump (Set) 4.1 General ▪ Non-self-priming in-line pump Pump for handling clean or aggressive fluids not chemically and mechanically aggressive to the pump materials. 4.2 Designation Example: Rio-Therm N 50-80 T Table 3: Key to the designation Code Description...
4 Description of the Pump (Set) 4.4 Design details Design ▪ Maintenance-free, screw-ended or flanged wet rotor pump (glandless) with up to four speed levels. Modes of operation ▪ Open-loop control mode (n = constant) with manual setpoint Automatic functions ▪...
4 Description of the Pump (Set) Discharge nozzle Plain bearing Motor Impeller Suction nozzle Motor shaft Design The pump is designed with a radial fluid inlet and a radial outlet arranged on the same axis. The impeller is rigidly connected to the motor shaft. The motor housing is equipped with a terminal box.
5 Installation at Site 5 Installation at Site 5.1 Safety regulations DANGER Installation in potentially explosive atmospheres Explosion hazard! ▷ Never install the pump in potentially explosive atmospheres. ▷ Observe the information given in the data sheet and on the name plates of the pump system.
5 Installation at Site NOTE The direction of flow of a vertically installed pump should be upwards. CAUTION Air entering the pump Damage to vertically installed pump sets whose direction of flow is downwards! ▷ Fit a vent valve at the highest point of the suction line. NOTE To prevent any impurities from collecting in the pump do not install the pump at the lowest point of the system.
5 Installation at Site Thoroughly clean, flush and blow through all vessels, pipelines and connections (especially of new installations). CAUTION Welding beads, scale and other impurities in the piping Damage to the pump! ▷ Free the piping from any impurities. 5.5 Casing/insulation WARNING The pump takes on same temperature as the fluid pumped...

5 Installation at Site up a view of the motor shaft. If the direction of rotation is incorrect, interchange any two phases. Prior to commissioning, the vent plug must be re-inserted and tightened with a suitable screwdriver. If the piping is not filled with water, the pump should only be operated for a short period of time to prevent any damage to the pump bearings (lubricated by the product pumped).
6 Commissioning/Start-up/Shutdown 6 Commissioning/Start-up/Shutdown 6.1 Commissioning/start-up 6.1.1 Prerequisites for commissioning/start-up Before commissioning/starting up the pump set, make sure that the following conditions are met: ▪ The pump set has been properly connected to the power supply and is equipped with all protection devices. ▪...
Page 20
6 Commissioning/Start-up/Shutdown CAUTION Abnormal noises, vibrations, temperatures or leakage Damage to the pump! ▷ Switch off the pump (set) immediately. ▷ Eliminate the causes before returning the pump set to service. ✓ The system piping has been cleaned. ✓ Pump, suction line and inlet tank, if any, have been vented and primed with the fluid to be pumped.
6 Commissioning/Start-up/Shutdown 6.1.4 Mode of operation 6.1.4.1 Open-loop control mode with manual setpoint input The pump is operated at the set speed level (characteristic curve). The required speed level is selected by turning the control knob at the control module. In this example (see illustration) the pump is operated at medium speed.
6 Commissioning/Start-up/Shutdown 6.3.1 Ambient temperature CAUTION Operation outside the permissible ambient temperature Damage to the pump (set)! ▷ Observe the specified limits for permissible ambient temperatures. Observe the following parameters and values during operation: Table 7: Temperature of the fluid pump as a function of the ambient temperature [°C] Product temperature Ambient temperature...
7 Servicing/Maintenance 7 Servicing/Maintenance 7.1 Servicing/inspection The circulator pumps are almost maintenance-free. If the pump has not been in operation for a prolonged period of time or if the system is severely contaminated, the rotor can become locked. The rotor can be unlocked by undoing the screwed plug, inserting a screw driver into the shaft end, and rotating the rotor.
