(1) To prevent the operation of the pump during work, check that the main power is turned off.
(2) Insert the mechanical seal into the main shaft of the pump.
(3) Fix the mechanical seal to the casing using the hexagon socket bolts
.
(4) Push the main shaft of the pump downward, and check that the main shaft system is completely
located at the lowest position.
(5) Uniformly tighten the three set screws
.
[* Recommended tightening torque: 2.5 [N
･
m] (M5 screws), 8 [N
･
m] (M6 screws)]
(6) Move the main shaft of the pump upward, and insert the plate
into the clearance at the upper part of
the mechanical seal.
(7) For a pump with a motor output of 7.5 kW or less, install the motor.
(8) For the models of ASVM(N)(G) 50 or less, pass the parallel pin through the holes of the main shaft of
the pump and coupling.
For the models of ASVM(N)(G) 65 or more, there is no parallel pin. Align the upper end of the main
shaft of the pump with the upper end of the shaft hole of the coupling as shown in the figure below.
(9)
While adjusting the clearances on both sides of the coupling in such a way that they are uniform,
fix the coupling using the fixing bolts
.
[* Recommended tightening torque: 13 [N
･
m] (M6 screws), 31 [N
･
m] (M8 screws), 62 [N
･
m] (M10
screws)]
(10) Remove the plate
, and rotate the coupling by hand.
Check that the shaft rotates smoothly and that rotation is not unusually hard.
(11)
Attach the coupling guard, and tighten the screws.
This completes the installation work of the mechanical seal.
