SERVICE

Your Aurora pump requires no maintenance other than periodic
inspection, and occasional cleaning and lubrication of bearings.
The intent of inspection is to prevent breakdown, thus obtaining
optimum service life. The liquid end of the pump is lubricated
by the fluid being pumped and therefore does not require
periodic lubrication. The motor, however may require
lubrication, in which case, the motor manufacturer’s
recommendation should be followed.

REPAIRS

Before starting any work, insure the electrial power is locked
out, the system pressure has been lowered to 0 psi and
temperature of the unit is at a safe level.

Warning: Electrical Shock Hazard

All electrical connections are to be made by a qualified
electrician in accordance with all codes and ordinances.
Failure to follow these instructions could result in serious
personal injury, death or property damage.

Warning: Electrical Overload Hazard

Insure all motors have properly sized overload protection.
Failure to follow these instructions could result in serious
personal injury, death or property damage.

Warning: Sudden Start-Up Hazard

Disconnect and lockout power source before servicing.
Failure to follow these instructions could result in serious
personal injury, death or property damage.

Warning: Hot Surface Hazard

If pumping hot water, insure guards or proper insulation is
installed to protect against skin contact to hot piping or
pump components. Failure to follow these instructions could
result in serious personal injury, death or property damage.

Warning: Spraying Water Hazard

When servicing pump replace all gaskets and seals. Do not
re-use old gaskets or seals. Failure to follow these
instructions could result in serious personal injury, death or
property damage.

Warning: High Pressure Hazard

The pump is rated at a maximum of 175 psi at 150°F. Do
not exceed this pressure. Install properly sized pressure
relief valves in system. Failure to follow these instructions
could result in serious personal injury, death or property
damage.

Warning: Expansion Hazard

Water expands when heated. Install properly sized thermal
expansion tanks and relief valves. Failure to follow these
instructions could result in serious personal injury, death or
property damage.

Warning: Sudden Start-Up Hazard

Disconnect and lockout power source before servicing.
Failure to follow these instructions could result in serious
personal injury, death or property damage.

Warning: Spraying Water Hazard

When servicing pump replace all gaskets and seals. Do not
re-use old gaskets or seals. Failure to follow these
instructions could result in serious personal injury, death or
property damage.

INSTRUCTION AND REPAIR MANUAL

SECTION 6 ITEM 330
DATED FEBRUARY 2001

MODEL 330

Inspect removed parts at disassembly to determine if they can
be reused. Cracked castings should never be reused. Scored or
worn pump shafts should be replaced. Gaskets should be
replaced at reassembly simply as a matter of economy. They are
much less expensive to replace routinely than to replace
individually as the need arises. While motors and motor
controls are often returned to the manufacturer for repairs it is
usually more practical and economical to repair the pump at the
job site or the pump repair shop.

Cleaning of most parts can be accomplished with the use of
clean rags.

DISASSEMBL

Y OF THE PUMP. READ AND
UNDERSTAND ALL SAFETY WARNINGS AT THE
BEGINNING OF THE MANUAL BEFORE BEGINNING
INSTALLATION OR ANY REPAIR WORK. Disassemble only
what is needed to make repairs or accomplish inspection.

PROCEDURE FOR REMOVING AND INSTALLING PUMP
MOTOR.

DO NOT OPERATE THIS UNIT DRY

TO REMOVE MOTOR

1. Support motor on both sides. Remove four hex head cap
screws (24) that hold motor to volute (9).

2. Carefully and slowly pull motor (25) until seal flange (19)
and impeller (17) are completely out of the volute (9). Avoid
resting entire unit on seal flange or impeller.

3. Remove Allen head lock screw (15) and washer (16) from
center of impeller (17). Pull impeller from shaft. Do no lose
square key (23).

4. Remove seal spring member (18) from shaft. Avoid cutting
rubber parts or scratching carbon face.

5. Remove two hex head cap screws (21) from seal flange (19).
Hold seal flange so that it doesn’t drop on motor shaft while
removing screws. Remove seal flange.

6. Remove ceramic seal face member (18) from center of seal
flange (19) and o-ring (20) from groove. Check for nicks and
cuts. Replace as necessary.

7. Finally, remove water slinger (22) if replacing with new one
or servicing motor.

TO INSTALL MOTOR

1. Slip water slinger (22) on motor shaft past shoulder.

2. Press ceramic seal face member (18) into center cavity of seal
flange (19) with the smooth ceramic facing out. Clean and
grease o-ring (20) and place in seal flange groove.

NOTE: MAKE SURE THAT CERAMIC FACE IS FREE
FROM OIL OR GREASE.

3. Install seal flange on motor register and secure in place with
two cap screws (21).

4. Press seal spring member (18) on motor shaft with carbon
face towards ceramic seal member. Avoid cutting rubber parts
on shaft.

5. Line up keyways and push impeller (17) on motor shaft up to
shoulder. Insert square key (23) in place.

6. Secure impeller with washer (16), impeller gasket (16.5) and
Allen head lock screw (15).

7. Position and carefully install assembled motor unit to the
volute (9) and secure motor using cap screws (24).

MOTOR MUST BE WIRED AS INDICATED ON MOTOR
JUNCTION BOX COVER AND NAME PLATE.

Remove motor shaft and cap. Momentarily, start and stop
motor-while impeller is still turning, check end shaft rotation.
Rotation must be in the direction indicated by the arrow on the
outside of the volute (9). Fill strainer pot with water, install
baseket, and secure cover. Pump is ready for operation. Press in
motor shaft end cap.

ST

ARTING PUMP AFTER REASSEMBLY. Do not start
pump until all air and vapor has been bled and there is liquid in
the pump to provide the necessary lubrication. It is possible that
the mechanical seal may drip during first few minutes of
operation.

Warning: Use of Solvents

We do not recommend the use of solvents or petroleum
cleaners for cleaning the parts because of the fire danger.
Failure to follow these instructions could result in serious
personal injury, death or property damage.
