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 instruc- tions are very important for protecting pump users or other persons from hazard or from loss of assets. - Page 4 Safety Section Warning • Magnet field danger The magnet drive pumps contain very strong magnets. The strong magnet field could adversely affect persons who are assisted by electronic devices such as pacemakers etc. • Always turn off power supply prior to maintenance works etc. Pay special attention so that no other operator turns on by mistake the power supply while someone is working on the pump.
- Page 5 Safety Section CAUTION • Attention to magnetic force This pump employs strong magnets. Special attention must be paid not to be injured by attracting force of magnets. Follow the procedure "Disassembling and Assembling" when the maintenance works are done. • Do not run pump dry Do not run pump dry (without liquid).

When the clearance between bearing inner dia. and spindle outer dia. exceeds 1 mm, replace by new ones. - Page 24 1. Disassembly of pump casing (1) Remove hex. bolts (909.1) and drain plate (122.1) to drain liquid inside. For the type without drain, disassemble the pump after the liquid inside is neutralized or the pump is cleaned by water. Warning If all the hex.
- Page 25 (7) Then, remove rear casing (158) from rear casing cover (159). If rear casing is hard to remove, remove it by turning. Pay attention not to drop the impeller (230)/magnet capsule (859) unit which is located in the rear casing. 2.
- Page 26 (3) Remove impeller fixing pin (942) of upper part of magnet capsule by pushing it by screw driver or like. (Ask IWAKI for removing impeller of PFA material type.) (4) Remove impeller (230) from magnet capsule (859). If it is hard to remove, slightly strike the impeller back side with plastic hammer.
- Page 27 4. Replacement of spindle (1) Spindle (210) is slightly pressed into rear casing (158). Pull out the spindle by a hand. If it is hard to pull it out, pull it out by shaking it right and left. (2) Wipe off the stain at spindle inserted part of rear casing and insert the spindle.
- Page 28 6. Assembling Assemble the pump in reverse procedures paying atten- tion to the following points. • Replacement of gasket Do not fail to replace the gasket by new one. Pay atten- tion so that it cannot be forgotten to be put or it can be mounted correctly without twist or bite.
