CIRCULATORS ecocirc® SC Solar Pump
Spherical Motor Pump
Application
• The ecocirc solar pump can be used for most circulation pump
applications without connection to the power grid with direct
connection a photovoltaic panel.
• This pump is perfect for single family home thermal
solar systems or any circulation pump application where
conventional power is not available.
Design
• The only moving part is a hemispherical rotor/impeller unit
which sits on an ultra-hard, wear-resistant ceramic ball.
• There are no conventional shaft bearings or seals eliminating
bearing noise and seal leaks.
• This pump is robust and has an estimated service life in excess
of 50,000 hours.
• The self-realigning bearing is lubricated and cooled by the
media.
• Even after prolonged shutdown, the pump will start reliably.
• All parts exposed to the uid are completely corrosion resistant.
Soft Start-up
• When the photovoltaic panel provides suffi cient power, the
pump goes through the alignment phase by turning the rotor
into the position required for start-up.
• The processor then waits until the capacitor is suffi ciently
charged.
• This enables a start-up with minimal power (less than one watt).
Over-temperature Safety Device
• The ecocirc Solar pump comes with an integrated over-
temperature safety device which shuts off the pump electronics
when reaching temperatures over 230°F.
• When the temperature of the pumped uid is below 203°F the
pump will function normally.
• The temperature of the electronic components is in uenced
by the temperature of the pumped media and by the speed
setting.
• After reaching a critical temperature 203°F the pump will lower
its speed automatically in order to avoid a total shutdown.
• However, if the temperature continues to rise the pump will
eventually shut down completely and automatically restart
after cooling down.

1
B&G Motor — The heart of the Booster.
The finest circulator motor available.
Sleeve bearing, oil lubricated with
replaceable resilient motor mounts.
B&G motors are designed and
manufactured specifically for the
B&G boosters.
2
Noise dampening coupler. B&G’s own
flexible spring design adds to quiet
operation. Do not accept a substitute.
3
Long bronze sleeve bearings maintain
exact shaft alignment. Provides for constant
circulation of oil over bearing surfaces.
4
Precision ground pump shaft is
oversized to provide large bearing
surfaces. Hardened integral thrust
collar minimizes end-thrust to
ensure long seal and bearing life.
5
The B&G mechanical seal is
designed to withstand the wide
range of water temperatures,
pressures, additives and dissolved
solids common in hydronic
systems.
6
Centrifugal impeller prevents
accumulation of air at seal faces to assure
long life. Close impeller/body tolerances
minimize water slippage and maximize
efficiency.

TC-1 Automatic Timer Kit (Part No. 113210)
To increase the overall efficiency of a hot water recirculation
system, the TC-1 timer control kit can be installed for use on any
B&G NBF circulator. The TC-1 timer control is programmable to
turn the circulator ON and OFF automatically at preset times.
This permits the user to have the pump circulate hot water only
during those times when high usage can be expected throughout
the day. Power supply minimum interval switch is 15 minutes.
Run modes maximum switch current is 16 amps.
Description
To increase the overall efficiency of a domestic hot water recirculating system and to reduce water
wasted while waiting for hot water, the e3 Timer can be installed on all e3 pumps. The timer is easily
installed by removing the motor end cap, plugging in the timer and setting the timer schedule
without any wiring. The timer can be used in 3-different selections: ON, OFF and TIMER. The ON
selection operates the pump continuously, the OFF selection turns the pump OFF and the TIMER
selection (depicted by a clock on the timer) turns the pump on when programmed.
Operational Limits
Power Supply: Internally powered by the e3 circulating pump.
Minimum Switch Interval: 30 minutes.
Run Modes: ON (Continuous), OFF (Off at all times) and TIMER
(run at programmed intervals)
AQS-1/2 (Part No. 113223) and
AQS-3/4 (Part No. 113224) Aquastat
Designed to thermostatically turn any B&G NBF circulator ON and
OFF. The AQ-1/2 or AQ-3/4 will switch the pump OFF at 120ºF
(48.9ºC) and ON at 100ºF (37.8ºC). The aquastats are available in
separate models that will sense the temperature for either 1/2” or
3/4” copper pipe.
AQS-1/2” clips onto 1/2” copper pipe or 3/8” steel pipe
AQS-3/4” clips onto 3/4” copper pipe or 1/2” steel pipe

RELAYS ZONETROL II AZ-1A™ Snap-On Pump Relay
Description
The ZONETROL II AZ-1A snap on relay box is an easy to install single zone
pump controller that mounts directly on any Bell & Gossett wet rotor circulator
NRF/NBF or Series PL booster. The AZ-1A turns the pump and boiler ON as
thermostat calls for heat. Using the wire nuts provided with the package, the
AZ-1A is quickly assembled onto any NRF/NBF or 1/12 to 1/6 HP Series PL.
The clearly marked TT terminals for the thermostat and the XX isolated end
switch terminals make the rest of the hook-up a snap. The AZ-1A can be daisy-
chained together to form a maximum of three zones.
The Bell & Gossett AZ-1A is ideal for any single to three zone pump
application. Or can be used when adding a zone to an existing system.
There’s no more need to have a pump controller hanging on the wall, simply
install the AZ-1A to our NRF/NBF or Series PL circulators and you are finished.
Features
• Snap-on design allows the AZ-1A to be quickly attached
to any B&G wet rotor circulator, reducing your inventory
investment (no need to carry “special” circulators with
factory mounted controllers)
• Clearly marked terminals make for sure, fast wiring of
the system
• Compact design fits in tight locations and presents a
clean professional appearence
• 100% factory tested assures reliable operation
• 5 year warranty — the best in the industry
• Daisy-Chain the AZ-1A relays to form up to three zones
• Can be used on any B&G model NRF, NBF or 1/12 to 1/6
HP Series PL pumps

Specifications
Description
The Hydrotrol (HT) flow control valve is used to prevent overheating of zones
due to gravity flow in hydronic heating systems and will permit summer-winter
operation of indirect water heater. The HT valve allows fluid to pass when the
system or zone pumps start. When the system or zone pumps are not operating,
the HT valve remains closed, preventing gravity circulation. The HT valves are
designed with a 1/2 turn knob that can be manually opened when draining
the system or for bypass purposes. The HT valve can be installed in either the
horizontal or vertical orientation.

Description
Bell & Gossett’s Model EASB-
JR Enhanced Air Separator
automatically removes entrained
air bubbles in hydronic systems. As
fluid enters the EASB-JR, the velocity
is decreased creating a low pressure
area. The small bubbles are released
from fluid and then collected on
the coalescing medium. As the
bubbles coalesce, they rise to the
top of the air separator where they
are released to atmosphere through
the built-in automatic air vent. The
air separator has a bottom 1/2”
NPT connection to accommodate
a B&G diaphragm expansion tank.
The compact design and brass body
construction make the EASB-JR
ideal for residential and commercial
hydronic heating systems.
How It Works
1 As system fluid enters
through the inlet, (either
straight or angle) the diffuser
distributes flow evenly across
the stainless steel, wire
brush-like medium.
2 Air bubbles, even micro air
bubbles, stick to the brush
filaments.
3 Trapped air rises above the
diffuser through a baffle (not
pictured), where the air is
then released through
an opening on top.
4 Deaerated water then goes
back into the system.

TANKS HFT Diaphragm Tanks • Expansion Tanks for Hydronic Heating
Airtrol® Tank Fittings
Directs free air to the compression tank. Restricts thermal
circulation to boiler. Establishes initial tank air level. Allows
compression tank size reduction.
Bell & Gossett HFT expansion tanks
are designed to absorb the force
of thermal expansion in hydronic
heating systems. Series HFT tanks
for hydronic heating systems
are available in sizes from 2—86
gallons. The Series HFT tank is
designed to absorb the force of
thermal expansion of heating water
to maintain proper pressurization
in a closed hydronic system. The
heavy duty butyl diaphragm
separates system water from the
air in the tank preventing water
logging problems.

Specifications
Description
Combination full port shut-off valve and drain valve used
to connect an expansion tank to the system. It is important
that the pre-charge in an expansion tank be maintained at
the proper pressure at all times. This pressure is the lowest
system operating pressure. When the tank’s pressure is
adjusted, there should be no system liquid in it. This
pre-charge should be checked and adjusted when:
• Tank is first installed
• If system is started or operating with the incorrect
tank pre-charge
• Annually to assure proper pre-charge pressure at all times
The TPV (Tank Purge Valve) is ideal for this as the tank can
be isolated from the system, drained and the pre-charge
checked and adjusted without draining or shutting down
the system.
The TPV also serves as a service valve should the tank need to
be removed or have the bladder changed. These valves are
furnished standard with a drain valve with a standard 5/8”
hose connection.
These valves are not recommended to be used on
potable water tanks.

HEAT EXCHANGERS Brazed Plate Heat Exchangers
Description
Model BPX brazed plate heat exchangers offer the highest level
of thermal efficiency and durability in a compact, low cost unit.
The corrugated plate design provides very high heat transfer
coefficients, resulting in a more compact design. The unit’s
stainless steel plates are vacuum brazed together to form a
durable, integral piece that can withstand high pressure
and temperature.
The BPX heat exchangers offer a compact design compared to
shell and tube exchangers
• 1/6 the size of shell and tube
• 1/5 the weight of shell and tube
• 1/8 the liquid required of shell and tube
• 1/3 to 1/5 of the surface area required
BPX units are ideal for a wide variety
of hydronic applications such as:
• Radiant Floor Heating
• Domestic Water Heating
• Snow MELT Systems
• Swimming Pool Heating

1) Provides approx. 2º F per hour heating with 180º F boiler to achieve 80º F pool temperature.
2) Pool water flow rate usually requires flow by pass from main pool circulation.
3) Chlorinated pool water can be corrosive to SS316L and Copper. Proper control of chlorine levels is
required or alternate materials of construction should be considered.
Estimate how much heat you need:
Flow x Temperature Rise x 500 = Heat load
Example: (20 GPM) (20º F) (500) = 200,000 BTU/Hr
For a Radiant Heating Application, the choice would
be a BP400-40.

1) Provides approx. 2º F per hour heating with 180º F boiler to achieve 80º F pool temperature.
2) Pool water flow rate usually requires flow by pass from main pool circulation.
3) Chlorinated pool water can be corrosive to SS316L and Copper. Proper control of chlorine levels is
required or alternate materials of construction should be considered.
Estimate how much heat you need:
Flow x Temperature Rise x 500 = Heat load
Example: (20 GPM) (20º F) (500) = 200,000 BTU/Hr
For a Radiant Heating Application, the choice would
be a BP400-40.

1) Provides approx. 2º F per hour heating with 180º F boiler to achieve 80º F pool temperature.
2) Pool water flow rate usually requires flow by pass from main pool circulation.
3) Chlorinated pool water can be corrosive to SS316L and Copper. Proper control of chlorine levels is
required or alternate materials of construction should be considered.
Estimate how much heat you need:
Flow x Temperature Rise x 500 = Heat load
Example: (20 GPM) (20º F) (500) = 200,000 BTU/Hr
For a Radiant Heating Application, the choice would
be a BP400-40.

1) Provides approx. 2º F per hour heating with 180º F boiler to achieve 80º F pool temperature.
2) Pool water flow rate usually requires flow by pass from main pool circulation.
3) Chlorinated pool water can be corrosive to SS316L and Copper. Proper control of chlorine levels is
required or alternate materials of construction should be considered.
Estimate how much heat you need:
Flow x Temperature Rise x 500 = Heat load
Example: (20 GPM) (20º F) (500) = 200,000 BTU/Hr
For a Radiant Heating Application, the choice would
be a BP400-40.
