The Practical Pumping Handbook

10.1.3 Handling
When lifting the pump unit it is essential to use proper lifting
techniques and to follow the instruction provided by the pump
supplier. It is important to realize that some manufacturers include
lifting eyes or eye bolts on various parts of the pump, but that these are
designed for lifting only these items and not for lifting the complete
pump assembly. A pump should be lifted by positioning the slings
around the pump casing and below the bearing housing. When lifting a
baseplate mounted assembly, the sling should be under the pump
casing and the driver.

10.1.4 Foundation leveling
A proper foundation and grouting can mean the difference between a
unit that gives many years of trouble-free service and one that requires
constant realignment. It should therefore be everyone's concern that
only the best of materials, together with proper design, be used when
performing this important function.

The concrete foundation must be sufficiently substantial to absorb any
vibration and to form a permanent rigid support for the baseplate. A
rule of thumb that is frequently used is that the foundation should
be about 5 times the weight of the pump/motor assembly, and
approximately 6 inches longer and wider than the baseplate. The
anchor bolts are usually of the sleeve type or the 'J' type shown in
Figure 10.1 and must be located in accordance with the certified
outline drawing of the baseplate.
