Iron & Bronze Booster Pumps
INSTALLER: PLEASE LEAVE THIS MANUAL FOR THE OWNER’S USE.
Bell & Gossett Booster Pumps feature oil lubricated sleeve
bearings, a carbon/ceramic seal and a noise dampening spring
coupler. Bell & Gossett Booster Pump motors are designed
specifically for quiet operation and are built with thermal protection and drip-proof construction. The motor is nonover-loading at any point on the pump curve.
This pump is nonsubmersible, for indoor use only.
PUMP APPLICATION
Bell & Gossett Pumps may be used for water circulating applications in hydronic, solar and chilled water systems. Bell &
Gossett recommends that bronze constructed pumps be used
for pumping potable water. For other applications contact your
local Bell & Gossett Representative. Note that some local
codes require using a check valve in the supply line when recirculating potable water.

OPERATIONAL INSTRUCTIONS
WIRING INSTRUCTIONS
WARNING: ELECTRICAL SHOCK HAZARD
Disconnect and lockout the power before making
electrical connections. Failure to follow these instructions
could result in serious personal injury or death.
SYSTEM PREPARATION1
Prior to pump start up, closed heating and cooling systems
should be flushed with clean water and drained. The system
should then be filled with clean water having a PH between 7
and 9.
1. Remove the screws securing the conduit box cover (wiring
compartment) and lift off the cover. Attach the appropriate
size connector to the hole in the side of the conduit box.
LUBRICATION1
Although the new B&G pumps are test run at the factory, they
must be lubricated thoroughly before being placed in operation. Bell & Gossett supplies a high quality lubricant specifically for this purpose which can be purchased from any B&G
Representative (Part No. L23401). Proper lubrication procedurs are as follows:
1. PUMP BEARINGS – Fill the bearing frame according to the
oiling instructions decal. At the time of installation, add
approximately 1 oz. of B&G #20 weight non-detergent oil.
An SAE 20 (non-detergent) or 10W-30 oil may be substituted.
Re-lubrication is required at the start of each heating season, or every three months for continuous service. Relubricate with 1 teaspoon of oil. More frequent lubrication
may be required under adverse conditions such as high
ambient temperatures. Less frequent lubrication is required
if oil overflows from the reservoir.
2. MOTOR BEARINGS – Lubricate through the two motor oil
cups according to the lubrication decal. At the time of
installation the motor bearings use approx. 12 drops each.
At re-lubrication intervals fill each motor bearing with
approx. 6-8 drops. More or less frequent re-lubrication
may be required depending on the installation conditions.
NOTE: Over-oiling can cause motor mount deterioration and
may cause spillage onto surrounding surfaces. Deteriorated
motor mounts will lead to misalignment and excessive coupler
wear.
2. Using a minimum size 14 AWG copper electrical wire (refer
to your local code for wiring restrictions), wire the motor to
a 115 volt, 60 hertz, single phase power source.

3. Connect the ground wire to the green screw inside the
conduit box.
NOTE: Single phase motors are protected with inherent overheating devices and do not require external overload protection.
NOTE: If a motor with special characteristics is selected, the
electrical rating of the power source must be the same as that
of the motor.
WARNING: ELECTRICAL SHOCK HAZARD
Be certain that all connections are secure and the
conduit box cover is closed before electrical power is connected. Failure to follow these instructions could result in
serious personal injury, death and/or property damage.
CAUTION: SEAL DAMAGE HAZARD
Do not run the pump dry – seal damage may occur.
Failure to follow these instructions could result in moderate
personal injury and/or property damage.
PRIMING AND STARTING
Do not run B&G circulator pumps dry. Before starting, the
pump must be filled with water. Air should be vented from the
system by means of a system air vent or by an alternate method.
