TM 5-3895-374-24-2 construction pressure/temperature limits Flanges:    Raised    face    flanges    are    drilled    to    ANSI standards (150 lb.) Flange Locations: Suction-Horizontal, Discharge- Vertical Direction   of   Rotation:   Clockwise   when   viewed   from driven end. Bearings:  One  outboard  grease  lubricated  ball  bearing and one internal liquid flushed carbon sleeve bearing. * Pressure  equals  Suction  pressure  plus  differential  pressure  at  shut-off  (zero  flow):  suction  pressure  exceeds  70  PSIG consult SIHI factory. The  unique  SIHIZTN  design  places  the shaft  seal  in  the  cooler  region  near  the bearing housing.  Since the temperature in   the   shaft   seal   area   will   not   exceed 212°F.    (100°C.),  viton  shaft  seal  rings capable    of    continuous    operation    at 320°F.    (160°C)  provide  a  reliable  seal with  virtually  zero  leakage.    Should  the shaft seal develop a leak, the leakage is collected in a trap chamber between the shaft seal and the ball bearing.  The trap chamber  has  a  threaded  connection  to easily monitor or safely drain off excess heat carrier seepage. speed/temperature limits (page 3 - 1137)
