PUMP LOCATION

Locate the pump so there is sufficient room for inspection,

maintenance and service. If the use of a hoist or tackle is

needed, allow ample head room.

WARNING: Falling Object Hazard

Eyebolts or lifting lugs if provided are for lifting only

the components to which they are attached. Failure to fol-

low these instructions could result in serious personal injury

or death, and property damage.

If lifting of the entire pump is required, do so with slings placed

around the pump assembly as shown in Fig. 2A. Or if your

pump configuration looks like Fig. 2B, connect a nylon sling,

wire rope or chain to the brace ribs on the motor adapter. Use

one sling for each rib. Attach all slings together at least 2 ft,

above the top of the pump.

CAUTION: Some pumps may have the center of

gravity at, or slightly above, the lift point. This may

create a tipping hazard. To avoid this hazard securely bind

the lifting lines to the side of the motor using a strap or

chain wrapped securely around the top of the motor. Unit

should only be lifted vertically. Failure to follow these

instructions could result in serious personal injury or

death, and property damage.

Special precautions to avoid sound and vibration transmission

should be taken if the pump is to be located near a noise sen-

sitive area, a sound specialist should be consulted.

If the pump is not on a closed system, it should be placed as

near as possible to the source of the liquid supply, and located

to permit installation with the fewest number of bends or

elbows in the suction pipe.

The installation must be evaluated to determine that the Net

Positive Suction Head Available (NPSHA) meets or exceeds

the Net Positive Head Required (NPSHR), as stated by the

pump performance curve.
