Vertical
Vertical pumps may be mounted directly on a pit, using either the pump support plate only or in conjunc-
tion with a pit or tank cover. The units are shipped completely assembled except for motor, pit cover ( if
any), and float controls. Check all bolts and nuts on the entire unit to make sure they are securely tight-
ened. Connect float and controls as shown on
10.1 Sectional View and Parts List on page 55
.
Installation must be done with care to avoid damage and ensure proper operation. It is recommended
that a man be stationed inside the pit, whenever possible, to assist in the initial installation.
Lower the assembled pump (less motor) carefully into the pit. Guide unit carefully so that it does not
strike sides of pit. When unit is in place, level the support plate. Shim under support plate as required.
Pump must hang perfectly vertical to avoid placing a bending stress on the unit.
The support plate should be bolted to an adequately supported structure, substantial enough to absorb
any vibration and to form a permanent, rigid support for the unit.
Place motor on motor support and tighten bolts (with lock washers) snugly.
Alignment of the coupling is of extreme importance for trouble-free mechanical operation. Check for
alignment by laying a straight edge across coupling hubs at four points· 90 degrees apart. See
2: Alignment using straight edge on page 11
. When the straight edge rests evenly at all four points, the
coupling is aligned.
Figure 2: Alignment using straight edge
The machined faces of the motor support and motor will provide angular alignment. However, any foreign
material or burrs on the surface will destroy this alignment. Make sure surfaces are clean and smooth.
2.4 Installation - horizontal pumps
Bedplate mounted units are normally mounted on a concrete foundation of liberal thickness poured on a
solid footing, using a one-three-five mix. The foundation should be substantial in order to absorb any vi-
bration and to form a permanent, rigid support for the pumping unit.
1.
The location and size of foundation bolts are shown on the outline assembly drawing supplied for
the unit.
2.
When unit is mounted on a concrete foundation, each foundation bolt should be installed with a
pipe sleeve around it to allow for adjustment.
The I.D. of the sleeve should be 2-1/2-3 times the bolt diameter. Place a washer between the bolt
head and sleeve to hold bolts. See
Figure 3: Concrete foundation on page 12
.
3.
Stuff waste around bolts to prevent concrete from entering between bolt and sleeve. Bolts should
be of sufficient length so that they project through the nuts approximately ¼" after allowance has
been made for grouting, bedplate thickness, and nut thickness.
