  • Page 10: Technical Information

    4. Technical Information General description MAGSON magnetically coupled centrifugal pumps are non-self priming centrifugal pumps made of plastic and built in horizontal single-stage monoblock design. A magnetic coupling connects the pump to the motor and transmits the power of the motor to the impeller.

  • Page 14: Installation

    6. Installation Safety precautions WARNING Danger of getting jammed or bruised during installation of the pump If necessary, use lifting and holding devices suitable to the size and weight of the pump. Make sure that all installation work is done by competent and qualified personnel only. WARNING Danger of being hit by falling components If necessary, use lifting and holding devices suitable to the size and weight of the pump.

  • Page 15: Suction Line

    6.3.2 Suction line ATTENTION Risk of damaging the pump by cavitation When installing the suction line, make sure to meet the NSPH value given in the æ Appendix page 30 foll.. If the NPSH falls below this value, there will be cavitation resulting in running noise, drumming and vibration of the pump.

  • Page 16: Flange Or Threaded Connections

    6.3.4 Flange or threaded connections MAGSON MA pumps of types 4 to 6 are equipped with slip-on flanges as standard features. The rotating flange allows you to easily connect the pump without considering the angular position of the mating flange. Do not use hard material to seal the flange but appropriate elastomer seals.

  • Page 17: Electrical Connection

    3. Screw the threaded adapter to the pump housing using the strap wrench. Make sure that the O-ring fits exactly into the groove of the inner thread. 6.3.5 Electrical connection NOTE Qualified personnel only are allowed to connect the pump to the electrical mains. All electrical connections and the installation of additional protection devices has to be done in accordance with the regulations of your local power supplier and the VDE Association of German Electrical Engineers.

  • Page 18: Controlling The Direction Of Rotation

    6.3.6 Controlling the direction of rotation ATTENTION Dry-running will damage the pump Do not check the direction of rotation when there is no fluid in the pump! 1. Mind the direction of rotation indicated by an arrow on the pump. Before verifying it after the installation, fill the pump housing and suction line with water or fluid.

  • Page 19: Putting Into Operation

    Putting into operation Safety precautions WARNING Danger of breaking during operation Regularly check the pump for damages. If there is a damage, the pump must not be operated! Replace wearing parts at regular intervals. Do not operate the pump to other than the intended purpose. WARNING Risk of electrical hazards when touching parts carrying voltage by fault Fasten all loose connections.

  • Page 20: Possible Malfunction When Putting The Pump Into Operation

    WARNING Hazard of pressure Use a manometer at the discharge line to check the system pressure and prevent it from going beyond its limit specified in the technical data sheet (see Appendix). If the system pressure is too high, the rear casing may burst releasing fluid. When pressure testing the piping, take into account the maximum system pressure, but do not test the pump as well, if possible.

  • Page 21: Shut-Down Procedure

    8. Shut-down procedure 1. Switch off the motor. 2. Close the shut-off valves. 3. When some fluid remains within the pump, secure the shut-off valves to prevent an accidental opening. 4. In case of crystallizing fluids, heat both the pump and the piping. Protect freezing fluids against frost.

  • Page 22: Service And Maintenance

    9. Service and maintenance Safety precautions WARNING Risk of electrical hazards when touching parts carrying voltage by fault Only qualified and authorized personnel are allowed to work on motors at a standstill. The motors have to be disconnected and secured against any accidental start. Strictly follow the instructions of the motor manufacturer.

  • Page 23: Preventive Maintenance

    Preventive maintenance 9.3.1 Overall pump Check the pump at regular intervals for 1. vibrations or unusual noise, 2. a minimum volume flow of at least 5% of the maximum volume flow, 3. changes in normal operating conditions, overheating or dry-running, 4.

  • Page 24: Motor

    Replace the O-ring as soon as the elastomer shows signs of chemical attack, fissures or loss of elasticity. NOTE All spare parts are available at Sondermann Pumpen + Filter GmbH & Co. KG. See the Appendix for the spare parts lists. When delivering dirty, muddy or crystallizsing fluids, you should check and clean the pump at shorter intervals.

  • Page 25: Dismantling And Replacing The Motor

    Dismantling and replacing the motor The back pull-out design allows you to replace the entire drive unit without dismounting the pump. So neither the pump nor the piping have to be drained. Just loosen the 4 motor screws and pull the motor off the pump.

  • Page 26: Disassembling The Pump Head

    Disassembling the pump head Press out the sleeve bearing of the impeller magnet and replace it. Press out the shaft mounting of the front housing and replace it (Types 4-6). Use appropriate tools to press out the components. If in doubt, ask the manufacturer to replace them.
