threads. Position the valve as shown in Figure 2
with the discharge port pointing down.

Final Pump Assembly

(Figure 2)

Install the shaft key (22, Figure 4) in the keyways of
both shafts and reconnect the power source. Be
sure to install any guards used over the rotating
members.

Do not operate the pump without

the

guards in place over the rotating parts.
Exposed rotating parts can catch cloth
ing, fingers, or tools, causing severe in
jury to personnel.

Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure.

Be sure

the pump and power source have been

properly lubricated, see

LUBRICATION

.

Remove the fill cover assembly (29) and fill the
pump casing with clean liquid. Install the fill cover
gasket and cover. Install the clamp bar (30) and se
cure it with the capscrew (31). Refer to

OPERA

TION

, Section C, before putting the pump back

into service.

LUBRICATION

Seal Assembly

(Figure 4)

Before starting the pump, remove the vented plug
(10) and fill the seal cavity with approximately 60
ounces (1,8 liters) SAE No. 30 non‐detergent oil to
the middle of the seal oil level sight gauge (14)

and

maintain it at the middle of the gauge. Clean and
reinstall the vented plug. Maintain the oil at this
level.

NOTE

The white reflector in the sight gauge must be posi

tioned horizontally to provide proper drainage.

Bearings

(Figure 4)

The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu
larly through the bearing cavity oil level sight gauge
(14)

and maintain it at the middle of the gauge.

When lubrication is required, add SAE No. 30 non‐
detergent

oil through the hole for the air vent (12).

Do not

over‐lubricate. Over‐lubrication can cause

the bearings to over‐heat, resulting in premature
bearing failure.

NOTE

The white reflector in the sight gauge must be posi
tioned horizontally to provide proper drainage.

Under normal conditions, drain the bearing hous
ing once each year and refill with approximately 11
ounces (0,3 liter) clean oil. Change the oil more fre
quently if the pump is operated continuously or in
stalled in an environment with rapid temperature
change.

Monitor the condition of the bearing lubri
cant regularly for evidence of rust or mois
ture condensation. This is especially im
portant in areas where variable hot and
cold temperatures are common.

For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.

Power Source

Consult the literature supplied with the power
source, or contact your local power source repre
sentative.
