APPLICATION:

The Taco 1400 Series Hi-Capacity circulators are designed
for use on a wide range of hydronic heating, cooling or
domestic water re-circulating systems. Features include a
quiet running, close-coupled, thermally protected motor
assembly with permanent split-capacitor and permanently
lubricated bearings. A stainless steel face plate and
mechanical seal with a non-ferrous impeller make the 1400

ation on open or closed systems.
Note: Always use Bronze body circulators on open,
fresh water systems.
CAUTION: Taco "1400 Series" circulators are
designed for indoor use only.

OPERATING SPECIFICATIONS:

• Maximum Working Pressure: 150 psi (1000 kPa)

1. Disconnect and lock-out electrical supply to pump.
2. Close isolation valves on suction and discharge sides
of pump. If valves are not installed, the system may
need to be drained.

water to cool to 100ºF before removing old
pump or draining system. Leave drain valve
open until service/replacement is complete.
3. Remove capacitor box cover and disconnect electrical
supply lines to pump.
4. Loosen flange bolts and shift pump body slightly to
relieve any remaining system pressure.
5. Remove flange nuts/bolts and pump from system.
INSTALLATION OF "1400 SERIES" CIRCULATOR:
A. Location:
• Install pump with sufficient room for future inspection,
maintenance and service.
• It is recommended that isolation valves be installed on
the pump suction and discharge to simplify future ser-
vice or replacement without draining the system.
CAUTION: This pump has a mechanical seal
which, by design, will eventually wear and
leak. Allow access for periodic inspection
and leak detection.
drainage to prevent property damage.
1. Using teflon tape or high quality thread sealant, install
Taco companion flanges on threaded pipe ends to
ensure proper fit-up and leak protection.
