FI / SFI Frame-Mounted End Suction Pumps
FI Series Pumps provide the ultimate in reliability and ease of installation
for heating, air conditioning, pressure boosting, cooling water transfer, and
water supply applications.
Quiet, dependable and proven performance: that’s the FI Series. Now also
available featuring SelfSensing with ProBalance®, ECM motor options and
eLink™.
FI Series Details
Quiet, dependable power and proven performance.
FI Series Pumps meet the latest standards for hydraulic performance and
dimensional characteristics. Each is backed by Taco, Inc., a worldwide leader
in heating and cooling equipment for more than nine decades.
Improved bearing frame design features sealed for life bearings meeting all
industry requirements for a minimum
L 10 life of 60,000 hours. Improved design also incorporates a unique sealing
system which prevents the migration of water into the bearing frame.
An easy-to-replace, slip-on shaft sleeve facilitates seal maintenance in the
field and lowers maintenance costs.
The exclusive dry shaft design protects the pump shaft by eliminating contact
between the shaft and the circulating fluid.
Flush seal line taps allow the installation of a filter to protect the seal
from non-condensible particles present in systems. In addition, pressure
tappings on suction and discharge connections are provided as a standard
feature.
A fully welded, rigid structural steel base, with enclosed ends and open
grouting area reduces vibration and improves alignment. Taco FI Pumps are
ideally suited for a variety of applications, including heating, air
conditioning, pressure boosting, cooling water transfer, and water supply.

Support Documentation
Typical Specification
Furnish and install centrifugal end suction single stage pump(s) with
capacities and characteristics as shown on the plans.
Pumps shall be Taco Model FI or approved equal. Pump volute or casing shall be
center-line discharge for positive air venting constructed of class 30 cast
iron with integrally cast mounting feet. The pump may be fitted with an
optional replaceable bronze wear ring, drilled and tapped for gauge ports at
both the suction and discharge connections and for drain port at the bottom of
the casing. The pumps shall be capable of being serviced without disturbing
the system piping. The impeller shall be bronze and hydraulically balanced by
either back vanes or balancing holes. The impeller shall be dynamically
balanced to ANSI Grade G6.3 and shall be fitted to the shaft with a key. The
pump shall be close coupled to a NEMA standard JM regreaseable motor. The pump
shall incorporate a dry shaft design to prevent the circulating fluid from
contacting the shaft. The shaft shall be covered with a replaceable bronze
(stainless steel) shaft sleeve.
The cast iron pump bearing housing shall have heavy duty permanently
lubricated sealed for life ball bearings, replaceable without disturbing the
piping connections, and shall have a foot support at the driver end. The pump
shall have a self flushing seal design or a positive external seal flushing
line. Pump may be furnished with a seal flush line and a Purocell # 900
replaceable cartridge filter with shut-off isolation valve installed in the
seal flushing line. The filter shall have the ability to remove particles down
to five microns in size.
The pump seal shall be EPT Ceramic rated 250°F. The base shall be made of
structural steel. The base shall also include an integral drain pan. A
flexible coupler suitable for both across the line starting applications. as
well as variable torque loads associated with variable frequency drives, shall
connect the pump to the motor and shall be covered by a coupler guard.
Contractor shall level and grout each pump according to manufacturers
recommendations to ensure proper algnment prior to operation.

Additional Features
A giant leap forward for variable speed pumping
The Self-Sensing Series with ProBalance®. At the heart is the patent pending
SelfSensing ProBalance technology. The VFD’s SelfSensing capabilities make
fast, accurate do-it-yourself system balancing easy. Reduced balancing
contractor costs, no expensive wiring, and no additional sensors required.
Apply to ALL your pumping needs: both constant flow chiller/boiler pumps and
secondary variable flow pumps!
- Integrated pump and drive
- Pump automatically responds to system demand changes
- No remote sensors
- No complex wiring
- Multiple modes:
— Constant flow
— Constant pressure
— Flow compensation
— Duplex pump alternation
Parallel Pumping Configuration
The SelfSensing Modulating Pump Controller (MPC) stages individual pumps in
parallel configuration for best overall pumping efficiency. The MPC is capable
of operating 2 to 4 pumps in parallel for maximum efficiency. The Sensorless
Parallel Pump Controller provides single building automation systems
connection in either BACnet MSTP or Modbus RTU and is enclosed in a NEMA 4X
certified enclosure.
The ultimate in pump protection and electrical safety.
The SelfSensing Series also features automatic alerts with optional shutdown
for no-flow, dry-run, and end-of-curve operation. That means the seal is safe
should someone forget to open a valve or to run the pump without water.
What’s more, the unit is electronically protected for overload and locked
rotor conditions per UL 778 and CSA C22.2 No. 108, so the motor is protected —
a real crowd pleaser for insurance companies.
Presenting DIY Balancing
Every HVAC pump needs to be balanced by an expert who must account for
construction variables and safety factors. Whether constant or variable speed,
the balancing process has to be addressed at commissioning and startup. But
what if you could zero in on the true system resistance without inducing false
head and balance the pump yourself? You can with Taco’s Self Sensing Pro
Balance® technology. The benefits of Do-It-Yourself balancing:
- You’ll have control over your construction schedule and subcontractors
- Reduced installation costs
- You can help a LEED team get a job into their budget
What kind of savings can you expect?
Balancing a constant flow system with Taco drives saves lots of energy and
increases pump life dramatically. For example, a pump that would have run at
1750 rpm @ 60hz is balanced with technology to run at 1458 rpm @50hz.
Now the pump consumes 57% of the horsepower and runs 291 fewer revolutions per
minute. The savings translate to 419,000 cycles per day or 150M fewer cycles
very year.
As a result, the pump lasts longer, requires less maintenance, and uses less
energy.
To illustrate, using best practices and balancing with drives saved a
Tennessee hospital $3,000 in yearly electrical costs on 100 hp chiller pumps
running at 47 hz instead of 60 hz.
ProBalance® feature not available in Parallel Pumping Configuration.
