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 CI 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 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.

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 SelfSensing
ProBalance® 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 mainte-nance, 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.

environment. Our Oe package is simple, we take our pump, add a Permanent
Magnet motor, and top the equipment off with a drive to increase your savings
at slower speeds!Taco is the first company to bring ECM technology to
hydraulic pumps up to 30hp.
Oe Package including SelfSensing with ProBalance
Everything the Oe package has to offer and the added benefits of the Taco
programmed SelfSensing Drives!Increase your performance with the Taco
SelfSensing drives included with the Permanent Magnet motor pumps for the best
energy rating Taco has to offer. The added benefits of DIY balancing will
decrease the total cost of ownership over the lifetime of the pump.
A Variable Frequency Drive is required to operate the Permanent Magnet motor.
The Oe package cannot be sold without a drive.
