The  magnet  force  which  is  used  in  a  pump  is  powerful,  be  careful  of  it  during  disassembly  or 

assembly. As well make sure to close the suction and discharge valves during them.   

1.  Disassembly 

(1)  Drain the liquid remaining inside the pump and wash the interior thoroughly. 

(2)  Remove 8 hex socket head cap screws (M6) and remove the front casing. (Do not disassemble 

the front casing set to maintain the proper function.) 

(3)  Pull the impeller out to forward. Do not scratch them with care. 

(4)  When putting sharps such as scraper between the rear casing and rear motor bracket and lifting 

the rear casing, the rear casing is pull out to forward. 

2.  Assembly 

Assembly is in the reverse order of disassembly. Clean the sliding parts and O-rings thoroughly with 

no entering dust or scratch. As well tighten the bolts evenly. 

(1)  Install the rear casing with the shaft and the rear thrust ring to the motor with bracket with the 

outer magnet. 

(2)  Install the O-ring to the rear casing assemble with the front casing. 

(3)  Tighten 8 hex. socket head cap screws (M6) by required torque. 

 

Required torque: 2.5N

(4)  Pipe and prime the liquid (0.6L) fully from the priming cock.   

Note: 

When disassembly or assembly, it is recommended to replace O-ring. After assembly, remove   

           

the motor fan cover and turn the fan by a hand to check it rotates smoothly. 

<Rotation direction check of the motor> 

Check that the direction is clockwise as viewed from the motor fan cover at the start. If it is in reverse, 

switch two of the three phases in the three-phase power supply.
