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.
