Recommendations, Warnings & Installation
Receiving inspection
Upon receiving the pump, it should
be inspected for damage or
shortages. If damage has occurred,
file a claim immediately with the
company that delivered the pump. If
the manual is removed from the
packaging, do not lose or misplace.
Storage
Any product that is stored for a
period longer than six (6) months
from the date of purchase should be
bench tested prior to installation. A
bench test consists of, checking the
impeller to assure it is free turning
and a run test to assure the motor
(and switch if provided) operate
properly.
Controls
Manual models require a separate
approved pump control device or
panel for automatic operation. Be
sure the electrical specification of the
control selected properly match the
electrical specifications of the pump.
Installation
Location - The pump should be
located as near as possible to the
liquid to be pumped and in no case
should the pump be more than 25
feet above the surface of the liquid
supply. The pump should always be
as level as possible.
Allow a minimum of 18 inches in
front of the pump case cover or
hatch cover to permit easy removal
and access to the interior of the
pump. On belt driven units, allow a
minimum of 10 inches at the shaft
end to permit easy removal of the
pedestal or rotating cartridge.
All pump units rotate clockwise when
looking from the driven end of the
pump. The impellers are threaded on
the shaft and it is necessary to slide
one half of the flexible coupling back
when checking rotation in order to
eliminate the possibility of
unscrewing the impeller and
damaging the pump. NOTE: Where
impellers thread on pump shaft,
never check the direction of electric
motor rotation without first
disconnecting flexible coupling.
Locate the pump on a firm footing to
make sure the pump will not move
due to vibration. Flex coupled and V-
belt driven units should be
permanently grouted onto a cement
foundation. The pumps should be
level to provide favorable operating
conditions. In addition, the flexible
coupling should be realigned after
grouting in order to eliminate
excessive wear on the coupling.
Suction - It is advisable to use a
suction line of the same size as the
pump port size. All horizontal suction
lines should slope up to the pump to
avoid trapped air pockets. An
adjustable stand, pipe clamp or floor
flange must be installed to support
the weight of the suction line. Using
a smaller suction line than the pump
port size can cause internal damage
to the pump.
Pump Lubrication - The only part of
the pump requiring lubrication is the
bearing housing. The impeller and
shaft seal are lubricated by the liquid
being pumped and need no other
lubrication.
The bearing housing is factory filled
with 90 weight oil, for bearing
lubrication. The oil level in the
bearing housing should be
periodically checked. This is
accomplished by removing the oil
dip stick and checking oil level
shown on it. If oil is required, add
through the dip stick hole.
D O N OT O P E R AT E
PUMP WITHOUT LIQUID IN PUMP
BODY AS OPERATING DRY WILL
RESULT IN DAMAGE TO THE SEAL.
CAUTION
THIS PUMP SHOULD
NOT BE OPERATED WITHOUT A
STRAINER ON THE END OF THE
SUCTION LINE TO PREVENT STICKS,
S T O N E S , R A G S A N D O T H E R
FOREIGN MATTER FROM BEING
DRAWN INTO THE IMPELLER. THE
STRAINER SHOULD BE CLEANED
REGULARLY TO INSURE FULL FLOW.
CAUTION
Discharge - Connect discharge hose
or pipe to the side outlet on the
discharge tee or to the discharge
elbow.
Operation
Priming - Remove the priming
plug(s) (25) in the top of the pump
body (18), and fill the pump body
completely with liquid as free of
solids as possible. In freezing
weather, the pump should be primed
with warm water, if possible, to
prevent any damage that may be
caused by ice films within the pump.
Starting - Start pump by applying
power to motor or by starting engine
as outlined in the ENGINE or MOTOR
INSTRUCTION MANUAL.
Shutdown - Operation may be
discontinued by stopping the engine
as outlined in the ENGINE MANUAL
or by disconnecting electric power if
motor driven. When the pump has
been operating in freezing weather
or in liquid containing a considerable
amount of solids, it is advisable to
drain the pump body by removing
drain plug and flushing the solids out
of the body. Replace the drain plug.

Operation, Service & Repair
When replacing gasket and weight
assembly onto pump body make
sure that HINGE section of gasket is
at TOP and that LARGE weight is on
PUMP SIDE of gasket.
Body, Volute and Impeller -
Disconnect suction and discharge
piping. Remove hex. nuts (21) and
lockwashers (20) then remove body
(18) and O-ring (4) from seal plate
(38). Pull volute (15) and gasket (17)
from seal plate (38). Remove hex.
head screw (13) and shakeproof
washers (14). Unscrew the impeller
(12) from shaft (1) in the right hand
direction. Take note of the size and
quantity of shims (10) & (11) used.
Shaft Seal Service - Remove rotating
member, spring and retaining ring of
seal (9) from shaft. To remove
stationary, remove hex. nuts (34) and
lockwashers (37) and pull seal plate
(38) from coupling head (32). Press
stationary out of seal plate. If any
part shows wear or damage replace
complete seal (9).
HANDLE SEAL PARTS
WITH EXTREME CARE. DO NOT
DAMAGE LAPPED FACES.
CAUTION
Press off bearings (7) & (8) from shaft
(1). Remove hex. head screws (44),
lockwashers (47) & hex. nuts (48) and
pull coupling head (32) from bearing
frame (2), replace lip seal (36).
To reassemble, lightly oil ring and
press stationary into seal plate (38).
Lightly oil inner surface of stationary
and replace seal plate (38) onto
couplig head (32). With lapped
surface facing pedestal, slide rotating
member onto shaft until lapped faces
of rotating member and stationary
are together.
At reassembly make sure to use a
combination of impeller shims (10)
and (11) to result in an impeller-to-
body clearance of approximately
0.015" max.
Pedestal & Shaft - Remove hex.
head screws (5) and lockwashers (6)
from bearing frame (2). Remove
bearing cap (28), o-ring (41), lip seal
(42) and snap ring (52). Remove shaft,
slinger and bearing assembly. To
replace inboard bearing (7) remove
snap ring (27) and slinger (3).
REASSEMBLE REMAINDER OF PUMP
IN OPPOSITE ORDER. Refill coupling
head with gear oil and pedestal with
grease.
Check Valve Service - To clean out or
repair check valve, disconnect
suction piping. Remove hex. head
screw (24) and suction flange (23).
Remove gasket (22B), weights (22A),
(22F), hex. head screw (22D),
lockwasher (22C) and hex. nut (22E)
and replace if worn or damaged.
