Always disconnect power supply from motor before
servicing.
INSTALLATION:
For convenience, Aurora Circulators generally are installed
in vertical pipelines, but may be changed easily on the job for
horizontal pipelines or for opposite flow directions. To make
the change, remove the body capscrews, taking care body
gasket is kept in position, and rotate body to desired direction at
90˚ or 180˚ from the original position.
With arrow on body pointing in direction of flow, insert
body capscrews and tighten evenly. [On Models 325-357 and
1A–2A, a gap between bearing bracket and pump body (volute)
is normal. Do no overtighten body capscrews!] Turn pump
shaft manually at coupler to make sure shaft turns freely and
impeller does not rub in body. Always install with motor shaft
in a horizontal position with pump oil cups or oil well cover
on top.
Models 325-346 are shipped for down-discharge. All other
models are shipped for up-discharge as pumps of this size
usually are installed to pump upward on hydronic systems, so
the point of zero pressure change – namely, the compression
tank connection – can be made easily to the system on the
suction side of the circulator.
The pump should be installed in a position to permit proper
lubrication and servicing. Motor and bearing bracket are to be
kept free of insulation. Pump and motor unit are designed to
be supported by the inline piping only. Do not support in any
other manner. A height of approximately 4 feet above floor is
recommended. When placing pump between flanges, tighten
flange bolts evenly and do not tighten excessively.
Gate valves should be installed on discharge and suction side of
pump to facilitate service. On larger pump sizes, a check valve
should be located on discharge side of pump between pump
body and gate valve to prevent damage due to water hammer.
SYSTEM CLEANLINESS:
Before starting the pump, the system must be thoroughly
cleaned, flushed and drained, then replenished with clean
liquid. Welding slag and other foreign materials, “stopleak” and
cleaning compounds, excessive or improper water treatment –
all are detrimental to the pump internals. Guarantee will be void
if any of these conditions is allowed to exist.
STARTING UP:
The pump must be fully primed on start-up. Fill system piping
and pump body with liquid and vent complete system, turning
pump by hand to dislodge air from body. Make sure fittings and
drain valves are airtight, then add any additional fill required.
Check motor electrics against available supply, then start pump
making sure rotation is correct. When viewed from motor end,
rotation is counterclockwise on Models 325-346. On all other
models, rotation is clockwise. If pressure does not develop, stop
pump, recheck, vent and fill. Never attempt to fill system when
pump is running.
LUBRICATION:
Stop motor before lubricating. Do not over-oil or spill on
resilient motor rings. Do not force oil into cups, and stop
if cup fills before addition of specified amount.
PUMP LUBRICATION:
Immediately after pump is installed and before running, slowly
add the oil (SAE 30 non-detergent regular, supplied with pump)
to pump oil cup, located on top of bearing bracket:
Models 325–357 and 1A–2A 1/4 oz.
Models 369, 363–368 and 1-1/2B–3B 2 oz.
At the start of each following heating season, lubricate
with SAE 30 oil. For Models 325–357 and 1A–2A, add
approximately 1/4 oz. (Lubricate every 6 months for high
temperature or constant operation.) On Models 369, 363–368
and 1-1/2B–3B, be sure oil is visible at the top and center of
window on side of bracket and maintain this level at all times.
MOTOR LUBRICATION:
Stop motor before lubricating. Do not over-oil or spill on
resilient motor rings.
This motor has been lubricated properly at the factory. At
the start of each following heating season, however, on motors
with oil cups, add 15 drops SAE 30 non-detergent oil to each
motor cup.
If motor is fitted with grease fittings, follow the motor
manufacturer’s recommended procedure. Motors without oil
cups or grease fittings are custom-greased for several years
operation and require little or no attention.

SEAL REPLACEMENT:
Remove pump bracket from body. Remove the impeller,
damaged seal assembly, ceramic insert and rubber cup. Clean
the recess in bearing bracket coverplate and install a new
retainer cup and ceramic. Check the condition of the shaft
sleeve. If scored, replace the shaft assembly. Otherwise, clean
shaft extension and polish sleeve with fine crocus cloth, using a
rotating motion, if required.
Press against coupler end of shaft to take up play while pressing
new seal firmly against the stationary face. A slight amount of
clean vaseline may be put on shaft sleeve to assist installation.
Press down firmly and evenly, using 2 screwdrivers and
pushing against the 4 ears of driving band (the metal ring
around rubber bellows), or around top outer edge of driving
band on Models 325–357 and 1A–2A.
Do not use spring washer on Models 325, 332 & 335 current
style circulators, where recess to locate spring is provided on
impeller hub.
Continue pressing against coupler end of shaft, remount
impeller and reassemble the seal bearing assembly into body. If
necessary, install a new body gasket and clean gasket surface of
both volute and bracket.
Before operating pump, carefully check:
1. Is the pump primed?
2. Is rotation correct?
3. Is pump properly lubricated?
4. Does the power supply agree with data on
motor nameplate?
5. Is overload protection provided?
6. Is the system clean?
For domestic water systems use bronze body pumps.
