PUMP INSTALLATION
S & SX Series pumps have been evaluated for use with water or water based solutions.
Please contact the manufacturer for additional information.

7
Risk of electric shock. Pump models; S750C, SX750C, S750C-3,
SX750CSS (115v) are supplied with a grounding conductor and grounding-type
attachment plug. 230V single phase pumps and all three phase pumps do not come
with electric plug connectors. To reduce the risk of electric shock, be certain that it is
connected only to a properly grounded, grounding-type receptacle.
Lifting:
Attach a rope or lifting chain (not included) to the handle (or lifting rings) on the top of
the pump.
Do not lift the pump by the power cable or discharge hose/piping.
Proper lifting equipment (rope/chain must be used.
POSITIONING THE PUMP
BJM Pumps® S & SX Series pumps are designed to operate fully or
partially submerged. Avoid running the pump dry for extended periods of time.
Refer to data sheet for minimum submersion depth for your particular model. Data
sheets can be obtained online at www.flowsolutions.com or by calling Industrial Flow
Solutions Operating, LLC at 860-399-5937. As a general rule, S and SX Series side
discharge pumps can pump down to a level above the suction screen. Pumping lower
than screen will permit air to enter the pump and cavitate, lose prime or become air
bound.
Do not run the pump dry.
Pump liquid should not exceed a maximum temperature of 104°F.
Never place the pump on loose or soft ground. The pump may sink, preventing
water from reaching the impeller. Place on a solid surface or suspend the pump
with a lifting rope/chain. The S & SX Series pumps are provided with a suction
strainer to prevent large solids from clogging the impeller. Any spherical solids
which pass through the strainer should pass through the pump.
For maximum pumping capacity, use the proper size non-collapsible hose or rigid
piping. A check valve may be installed after the discharge to prevent back flow
when the pump is shut off.

8
PUMP ROTATION
Two ways to check the correct pump rotation:
1. By looking at the impeller; the rotation of the impeller should be counter
clockwise as shown in the picture below.
2. By looking from the top of the pump. Since the impeller cannot be seen, the best
way to check the rotation is to check the kick back motion of the pump when the
pump just starts. The kick back motion of the pump should be counter clockwise
as shown in the picture below.

9
PUMP OPERATION
This pump is designed to handle dirty water that contains some
solids. It is not designed to pump volatile or flammable liquids. Do not attempt to pump
any liquids which may damage the pump or endanger personnel as a result of pump
failure.
Do not operate this pump where explosive vapors or
flammable material exist. Death or Serious injury will result.
TYPICAL MANUAL DEWATERING INSTALLATION
NOTE: Maximum recommended starts should not exceed 10 times per hour.
All S & SX models are provided with a 33’ (10 m) power cable. NEVER splice the power
cable due to safety and warranty considerations. Always keep the plug end dry.
Note: 230V, single phase and 208V, 230V, 460V & 575V three phase units do not
have a plug and have to be provided separately.
Do not alter the length or repair any power cable with a splice. The
pump motor and cable must be completely waterproof. Damage to the pump or
personal injury may result from alterations.
For manual operation: 115 volt: plug the power cable into any 115 volt grounded
receptacle. 208, 230, 460 & 575 volt: Attach the proper plug, connect directly to the
power source or control box. Check the direction of the rotation. Tilt the pump and start
it. It should twist in the opposite direction of the arrow (on pump). It is recommended
that a Ground Fault Interrupter (GFI) type receptacle (or equivalent) be used.
Single phase pumps always use a three-prong grounded
receptacle. It is recommended that a Ground Fault Interrupter (GFI) type receptacle (or
equivalent) be used.
STOPPING
To stop the pump (manual and automatic mode), unplug it from the power source, turn
off the breaker, or turn the power source off (generator).

Float switches (wired into the pump motor or piggy-back style) are available from the
factory as an option.
Note: 208V, 230V, 460V & 575V pumps do not have a plug installed.
Three phase pumps need a separate control box with float(s) for automatic
operation.

11
STOPPING
To stop the pump (manual and automatic mode), unplug it from the power source, turn
off the breaker, or turn the power source off (generator).
INTENDED METHODS OF CONNECTION

load amperes. “UTILLISER UN DÉMARREAR APPROUVÉ CONVENANT AU
COURANT Á PLEINE CHARGE DU MOTEUR.”
BJM Pumps has been evaluated for use with water or water based solutions. Please
contact the manufacturer for additional information.
SINGLE PHASE WIRING INSTRUCTIONS
FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP
FROM ITS POWER SOURCE BEFORE HANDLING. Single phase pumps are supplied
with a three prong grounded plug to help protect you against the possibility of electrical
shock. DO NOT UNDER ANY CIRCUMSTANCES REMOVE THE GROUND PIN. The
three prong plug must be inserted into a mating three prong grounded receptacle. IF
the installation does not have such a receptacle it must be changed to the proper type,

12
wired and grounded in accordance with the National Electrical Code and all applicable
local codes and ordinances.
“Risk of electrical shock” Do not remove power supply cable and
strain relief or connect conduit directly to the pump.
Installation and checking of electrical circuits and hardware should
be performed by a qualified licensed electrician.
THREE PHASE WIRING INSTRUCTIONS
FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP
FROM ITS POWER SOURCE BEFORE HANDLING.
“Risk of electrical shock” Do not remove power supply cable and
strain relief or connect conduit directly to the pump.
Installation and checking of electrical circuits and hardware should
be performed by a qualified licensed electrician.
To automatically operate a non-automatic three phase pump, a control panel is
required. Follow the instructions provided with the panel to wire the system. For
automatic three phase pumps see automatic three phase wiring diagram.

13
Typical 3 phase Auto Control 1
Before installing a pump, check the pump rotation to insure that wiring has been
connected properly to power source, and that the green lead of power cable (See wiring
diagram), is connected to a valid ground, momentarily energize the pump, observing the
directions of kick back due to starting torque. Rotation is correct if kick back is in the
opposite direction of rotation arrow on the pump casing. If rotation is not correct,
switching of any two power leads other than ground will provide the proper rotation.
DO NOT PLACE HANDS IN PUMP SUCTION WHILE CHECKING
MOTOR ROTATION. TO DO SO WILL CAUSE SEVERE PERSONAL INJURY.
Three phase pumps have integral motor overload protection. It is recommended that all
three phase pumps using a motor starting device also incorporate motor overload
protection. Pumps must be installed in accordance with the National Electrical Code
and all applicable local codes and ordinances. Pumps are not to be installed in locations
classified as hazardous in accordance with National Electrical Code, ANSI/NFPA 70.
Connect pump to a junction box, outlet box, control box, enclosure with a wiring
compartment that meets NEC and local codes. The provision for supply connection
shall reduce the risk of water entry during temporary, limited submersion and shall
comply with the applicable requirements of the Standard for Enclosures for Electrical

14
Equipment, UL 50, or the standard for Metallic Outlet Boxes, UL 514A, and the standard
for Motor-Operated Water Pumps. UL 778.
TROUBLE SHOOTING
Disconnect the power source to the pump BEFORE attempting
any type of trouble shooting, service or repair.
PUMP WILL NOT RUN
1. Check power supply (fuses, breaker). Reset power.
2. Blocked impeller. Remove strainer, check and clean.
3. Defective cable or incorrect wiring.
4. Strainer clogged. Check and clean as necessary.
5. Float switch tangled/obstructed. Clean and free float switch from obstruction.
6. Float switch defective. Replace float switch.
7. Pump overheated or temperature of liquid exceeds pump operating
temperature.
Warning: Pump will restart automatically when motor over-heat protection switch
cools.
PUMP RUNS BUT DOES NOT DELIVER RATED CAPACITY
1. Discharge line clogged, restricted or hose kinked. Check discharge hose/pipe.
2. Worn impeller and/or suction cover. Inspect and replace as necessary.
3. Pump overloaded due to liquid pumped being too thick.
4. Pumping air. Check liquid level and position of pump.
5. Excessive voltage drops due to long cables.
6. Three phase only; pump running backwards, check rotation.
SERVICING YOUR SUBMERSIBLE PUMP
Pump should be disconnected from the electric power supply before proceeding to do
any service or maintenance.
To service or repair your pump, please contact your local BJM Pumps®
distributor. Service should only be performed by a qualified electrician.
MAINTAINING YOUR PUMP
Pump should be disconnected from the electric power supply before proceeding
to do any service or maintenance.

15
Pump should be inspected at regular intervals.
More frequent inspections are required if the pump is used in a harsh
environment.
Preventative maintenance should be performed to reduce the chance of
premature failure.
Worn impellers and lip seals should be replaced.
Cut or cracked power cables must be replaced. (Never operate a pump with a
cut, cracked or damaged power cable.)
Seal oil should be checked once per year.
Maintenance should always be done when taking a pump out of service before
storage.
The impeller to suction cover clearance should be adjusted to between 0.01” to
0.02” for optimal pumping performance. Shim kits are available if adjustment is
required.
1) Clean pump of dirt and other build up.
2) Check condition of oil around the shaft seals.
3) Check hydraulic parts: check for wear.
4) Inspect power cable. Make sure that it is free of nicks or cuts.
BJM Pump Impeller Shimming
To optimize the shredding performance of the SK/SKX/SKG BJM model shredding
pumps, and to optimize the hydraulic performance of the S/SX/J/JX/R/RX/KZN/KB/KZE
model pumps, BJM Pumps offers an impeller shim kit. The shims are designed to go on
the shaft behind the impeller to adjust the clearance between the impeller vane and the
suction cover to the target specification of the 0.010 inch to 0.020 inch. Note that given
the vortex design, the SV model vortex pumps do not require shimming of the impeller
to gain optimal performance.
Impeller Shimming Procedure
1. Install the impeller on the shaft and snug the retaining nut to keep the impeller in
location with any axial movement on the shaft. Note that some single phase
pumps have impellers that thread onto the shaft.
2. Using a prying bar, make sure the impeller is pulled completely down and that
the bearings or mechanical seals are not pulling the shaft upwards (toward the
motor top cover).
3. Install the suction cover and snug the retaining fasteners.
4. Using an angled set of feeler gauges, measure the clearance between the
impeller and the suction cover. Perform this measurement in various locations
and find the smallest clearance. This will be your minimum starting clearance.
5. Remove the suction cover and the impeller of the pump.
6. Subtract 0.010 inch and 0.020 inch from the minimum starting clearance to gain
your recommended shim height.

16
7. Select a set of shims that will give you a measurement that fits between your
minimum and maximum calculated shim height. Note that the closer the
clearance is to 0.010 inch, the better the shredding and hydraulic performance of
the pump.
8. Install the selected shims onto the pump shaft. Then, replace the drive key and
the impeller. Install the locking washer and the impeller nut, tightening the nut to
the proper torque.
9. Install the suction cover applying the proper torque to the remaining fasteners.
10. Using the angled set of feeler gauges, recheck the impeller clearance in various
locations. The measurement should fall between the 0.010 inch and 0.020 inch
specification. Caution, to not allow the clearance to be less than 0.010 inch since
this may cause undesirable rubbing of the impeller on the suction cover.
11. Repeat these steps as necessary to gain a clearance between the impeller and
the suction cover to 0.010 inch to 0.020 inch.
CHANGING SEAL OIL
Changing the seal oil in the S & SX Series pumps is very easy.
1) Make sure that the pump cable is disconnected from the power source.
2) Lay the pump down on its side.
3) Remove the screws that hold the bottom plate in place.
4) Remove bottom plate.
5) Remove screws holding the suction cover.
6) Remove the suction cover.
7) Remove the impeller.
8) Remove the inspection screw for the oil chamber (pos#50-08). Pour
out a small sample of the oil. If it is milky white, or contains water, then
the oil and possible, the mechanical seal, should be changed. If an oil
change is needed:
9) Remove the screws that hold the oil chamber cover in place & remove
the oil.
10) Replace the mechanical seal if necessary.
11) Replace the oil.
12) Assemble the pump.
