1. Instalation
1. 1. Mounting
Installation and leveling of the pump should be performed by skilled workers. Improper installation and leveling/
centering would cause various troubles during the pump running.
In the case of the pump directly coupled to the driver on the common baseplate, the pump set is shipped after
completely levelled and centered at our fabrication shop. However, follow the sequence given below for local installation
of the common baseplate and recheck the level and centering of pump and driver.
(1) Prepare packers and leveling shims or taper liners necessary for the common baseplate installation.
(2) After complete cure-up of the foundation concrete, place and position packers along the both sides of each
anchor bolt seat (if the shims are apart more than 800 mm, additional one more shim or extra shims at equi-
distance between them as shown in Fig. 2) so that the common baseplate locates thereon in specific
position. After each packer and shim (or taper liner) is positioned precisely, fix it by mortar application.

(3) In this case, adjust and keep each packer horizontally using a level gauge. The height of each packer is
fine-adjusted by means of shims when the common baseplate is installed. Therefore, in this stage it would
be sufficient only to keep each packer right horizontal.
(4) After complete cure-up of the mortar with packer on, temporarily install the common baseplate (with the
pump and driver installed thereon) onto the packers and check the center height of the pump. Furthermore,
hold a level gauge on the discharge flange to make fine-adjustment of the pump horizontality in both axial
and crosswise directions by inserting previously prepared leveling shims (taper liners).
For the pump that was shipped without the motor, adjust its horizontality in both axial and crosswise
directions by a level gauge being held in contact with the discharge flange surface and the motor mount
seat.
(5) After the pump was positioned and levelled as specified, make pre-center alignment between the pump and
the driver using a centering leveling jig ( refer to Para. 1.2 for the detail ).
(6) After the pre-centering work, grout mortar in each anchor hole.
(7) After complete cure-up of the mortar around each anchor bolt, tighten alternately the anchor (foundation)
bolts with uniform tightening torque.
(8) Grout mortar under the common baseplate until it reaches completely each corner so that any cavity does
not exist in the grouted mortar.
After complete cure-up of the grouted mortar, recheck the horizontality of the common baseplate.
(9) After completion of the above works, connect both the suction and the discharge pipes to the pump.
