Page 3: Safety Section
Safety Section For the Safe and Correct Handling of the Pump ● Before use of the pump, read carefully this "Safety Section" to prevent accidents and to avoid the damage or loss of other assets. ● Observe and abide by the instructions described in this "Safety Section". These instructions are very important for protecting pump users or other persons from hazard or from loss of assets. - Page 4 Safety Section WARNING ● Access limitation The magnet drive pump has a pair of strong magnets (the magnet capsule unit and drive magnet). The strong magnet field could adversely affect the Prohibition persons who are assisted by electronic devices such as the pacemaker. ●...
- Page 5 Safety Section CAUTION ● Do not catch the finger Magnetic force of the pump is powerful. Take care not to catch the finger in the bracket. Observe the instructions on the later pages for disassembly and assembly. ● Do not run pump dry Do not run pump dry (operation without priming water or with a suction valve closed).

Page 17: Precautions On Operation
9. Precautions on operation CAUTION ● Never operate pump dry or with suction side valve closed. ● Do not run pump dry (operation without priming water or with a suction valve closed). Otherwise, inter- nal parts are excessively worn by friction heat and fatal pump damage results. * If the pump runs dry by mistake, turn off power and leave it for more than one hour to cool it down. -
Page 18: Operation
10. Operation (Starting) 1. Fully close discharge valve and fully open suction valve. 2. Fill liquid into pump • In case of flooded suction, confirm if suction valve is fully opened. • In case of suction lift, prime to fill liquid into suction piping. 3. -

13. Maintenance & inspection Warning • Magnetic force is very strong. Pay attention when you handle the magnet capsule or driving magnet so that fingers can not be injured by attraction of magnets. • The persons who are assisted by electronic devices such as pacemakers etc. are prohibited to approach the magnet capsule and drive magnet. - Page 23 2.

Model New one Wear limit New one Wear limit MDM50-32-160, MDM65-40-160 MDM50-32-200, MDM80-50-160 Note1. When the clearance between bearing inner dia. and spindle outer dia. exceeds 1 mm, replace by new ones.
- Page 24 4. Ball bearing The life span of ball bearing is various depending on working temperature. The continuous working temperature of outer ball of the bearing must be below 70 deg.C. If the working temperature exceeds 70 deg.C, the deterioration of grease on bearing progresses. Secure the working condition within 70 deg.C of working temperature.

Screw in bolts alternatively to remove foot support backward. (Screw in bolts by approx. 75 mm). (7) Pull out backward bearing housing and bracket by lift- ing them by crane or so.
- Page 27 2. Removal of impeller and bearing (1) Stand up the claw of rear ring (314.4) after it was heated by plastic welder or industrial dryer. (2) Apply plastic made round bar of 34 mm dia. × 100L on the bearing end through impeller side and remove bear- ing (310) and rear ring (314.4) using hand press etc.
- Page 28 3. Replacement of mouth ring (1) Stand up the claw of impeller after it was heated by plas- tic welder or industrial dryer. (2) Replace the mouth ring (314.2), and fix it by heating the claw with plastic welder or industrial dryer and push the claw down.
- Page 29 6. Bearing housing dismantlement (1) Remove hex. head bolts (901.6). Be careful no to hit drive magnet unit with bracket when removing bracket. (2) Loosen hex. soch set screws (908.1) which are holding drive magnet unit. Remove the drive magnet unit from drive shaft.
- Page 30 (6) Use a puller to remove ball bearing (321.1)(321.2) from drive shaft. Be careful not to scratch the sliding surface between drive shaft and shaft seal (420). (7) Insert a flat head of screw driver between bearing hous- ing and shaft seat to remove shaft seal (420). In case bearing housing is scratched, sandpaper it.
- Page 31 7. Bearing housing assembly (1) Fit shaft seal (420) to bearing housing. Apply grease on the periphery of shaft seal and fit it with a press. In doing so, try not to scratch seal lip. (2) Fit ball bearing to drive shaft with a press. There is a dif- ference in size between front ball bearing and rear ball bearing.
- Page 32 8. Assembling Assemble the pump in reverse procedures paying attention to the following points. • Replacement of gasket Do not fail to replace the gasket by new one. Pay attention so that it cannot be forgotten to be put or it can be mounted correctly without twist or bite.
