NOTE

1  

Use this bulletin for preliminary layouts only.

 Obtain 

current drawings from your Marley sales representative.

2  Pumping head contributed by the tower is static lift 

“G”. Actual pumping head will vary according to tower 

circulating GPM. Total pumping head will be furnished at 

time of proposal.

3  If your application requires a bypass system, 

recommended location is through tower endwall into 

plenum area. Review of the system by SPX engineering is 

required.

4  Marley piping terminates at face of a cast iron flat face 

flange. Bolt circle conforms to class 125 lb. ANSI B 16.1 

specifications.

5  Supports on tower for crossover piping are part of the 

tower design. 

Do not support the riser’s dead load or 

operating load from the tower. Do not brace the riser’s 

seismic or thrust loads against the tower.

6  Butterfly valves or piping expansion joints (if used) are 

by others and must be located outside the limits of the 

cooling tower “

F

”.

7  Motor must be located 180° from inlet.
