Flanges: Raised face flanges are drilled to ANSI
standards (150 lb.)
Direction of Rotation: Clockwise when viewed from
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

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.
