2. Model 3406 - between 180º and 250ºF.
3. Model 3416 - between 250º and 350ºF when bearing housings are not cooled and between 350º
and 400ºF, in addition to bearing housing cooling.
4. Volatile or toxic, in order to smother the gland leakage, which then can be piped away.
The quenching liquid must be from an outside source and should be piped with a flexible pipe, into the
opening in the upper gland half and allowed to drain into chamber or pocket in lower half casing. When
used for cooling, the flow should be requlated as shown in regulation of cooling water flow. The openings
in the gland halves should be installed in each quenching line.
2.10 Connection of bearing cooling water piping
Water cooled bearing housings are furnished when ordered (Models 3405 and 3416 only). Bearing cool-
ing should be used when the liquid pumped is:
1. Model 3405 between 180° and 250°F when gland quenching is not used and between 250° and
350°F, in addition to gland quenching.
2. Model 3416 between 250° and 350°F when gland quenching is not used and between 350° and
400°F, in addition to gland quenching.
On the Model 3405 - cooling water lines should be connected to the 3/8" pipe tap openings in the
bearing housing, as shown in the sectional assembly,
7.3 Sectional view on page 39 . The inlet
line should be at the bottom, and should have a shut-off valve installed to regulate flow. See Reg-
ulation of cooling water flow for instructions for regulating cooling water flow.
On the Model 3416 - the cooling coils are installed as follows:
1. Refer to Figure 1, which shows the installed cooling coil.
2. Special fittings and tubing are in the box of fittings sent with the pump.
3. Remove four - ¼" plugs from bearing end covers (109 and 119) - one plug from each side of
each cover. The plugged openings are those below the openings for the constant level oilers.
4. Screw ¼" pipe x ¼" O.D. tube compression fittings into each of the four openings.
5. Push each ¼" 0.D. x 9" long copper tube through one fitting until it comes out the .fitting on the
other side. Center tubing so that equal lengths project from each side. Tighten nuts on compres-
sion fittings.
6. Connect the ¼" pipe x ¼" O.D. tubing elbow to each end of the copper tube. This provides a ¼"
pipe connection for cooling water piping.
7. Connect cooling water. The inlet line should have a shutoff valve to regulate flow.
2.11 Connection of drain piping
Connect overflow outlets from stuffing boxes (located in casing near pump feet) to drain, and connect
overflow from bedplate (located at pump end of bedplate) to drain. All of the above overflow openings
are tapped for ¾" pipe.
