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.

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.

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.

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.

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.
