1. Assembling the casing 【Assembly on the casing side】
①
Align the casing (on the suction side) with the volute liner and fit the volute liner flange
into the casing. Pull out the volute liner flange with a flat-tipped rod and firmly fit the flange
into the casing by hand.
※ The volute liner is made of rubber.
Be careful not to damage it.
②
Fit the volute liner into the casing (on the seal side),
too.
③
Temporarily fasten the casings (on the suction and seal sides) with the nuts and hexagon socket head
cap screws.
④
Hammer the knock pin into the casing from the direction shown in the
figure on the left below so that it protrudes about 3 mm above the base
plate and temporarily fasten the casing and base plate with the hexagon
socket head cap screws. Hammer the knock pin again so that it does
not protrude from the base plate. Then, firmly tighten the screws.
※ Use a copper hammer to prevent the knock pin from
deforming.
※ Pay attention to the orientation so that the internal thread
comes to the bottom of the pump. Thus, you can remove the knock pin
later.
⑤
Firmly tighten the nuts and hexagon socket head cap screws that have
been temporarily tightened in step ③.
⑥
Attach the suction and drain covers.
