Repeat this procedure to check the seal chamber for leaks.
Rotate the impeller shaft by hand prior to startup.
POSITIONING THE PUMP
BJM Pumps, J & JX Series pumps are designed to operate fully or partially submerged.
Do not run the pump dry. Refer to data sheet for minimum submersion depth for your
particular model. Data sheets can be obtained online at HHUUwww.bjmpumps.comUUHH or by
calling BJM Pumps, LLC at 860-399-5937. As a general rule, J and JX 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.
BJM Pumps, XP-JX 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.bjmpumps.com or by calling BJM Pumps, LLC at 860-399-5937. For
minimum submergence requirements, refer to EIM ELECTRIC CO., LTD Instruction
Manual for Installation, Operation and Maintenance for the Explosion Proof Submersible
Motors (EMQY Series; FM Approved for Class I, Division 1, Group C & D).
Do not run 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.
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 (recommended if static head is 30’ or greater).
Take stand off of pump when using slide rail. Keep stand and reattach when
transporting or handling the pump.

WIRING INSTRUCTIONS
Electrical wiring and protection must be in accordance with the National Electrical Code
per NEC articles 500 through 503 for installation in Class I, Division 1, Group C & D
Hazardous Locations, and any other applicable state and local electrical requirements.
For motor specifications, motor technical data, design features, power supply, electrical
wiring, operation, inspecting & maintenance, replacing shaft seals, replacing cables,
replacing bearings and other parts, repairing, storing and troubleshooting the
submersible electric motor, refer to EIM ELECTRIC CO., LTD Instruction Manual for
Installation, Operation and Maintenance for the Explosion Proof Submersible Motors
(EMQY Series; FM Approved for Class I, Division 1, Group C & D).
Note: All service work on the FM approved motor by EIM Electric Co., needs to be done
by an FM Approved repair facility.
The XP-SKX Series motors have a separate sensor cable for the motor thermal sensors
and Seal Minder. See Seal Minder - Thermal Motor Sensor Switch section in this
manual for proper connection method
PUMP ROTATION
DO NOT PLACE HANDS IN PUMP SUCTION WHILE CHECKING
MOTOR ROTATION. TO DO SO WILL CAUSE SEVERE PERSONAL INJURY.
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 cord (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.
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.

9
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.
PUMP OPERATION
This pump is designed to handle dirty water that contains some
solids. Do not attempt to pump any liquids which may damage the pump or endanger
personnel as a result of pump failure.
Consult EIM ELELCTRIC Co., LTD. Instruction Manual for Installation, Operation
and Maintenance before connecting, operating or conducting maintenance on the
Explosion Proof Submersible Motor.

10
STOPPING
To stop the pump (manual and automatic mode) turn off the breaker, or turn the
electrical power source off (generator).
TROUBLE SHOOTING
Disconnect the electrical power source to the pump BEFORE
attempting any type of trouble shooting, service or repair.
PUMP WILL NOT RUN
Refer to EIM ELECTRIC CO., LTD Instruction Manual for Installation, Operation and
Maintenance for the Explosion Proof Submersible Motors (EMQY Series; FM Approved
for Class I, Division 1, Group C & D).
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. Pump running backwards, check rotation.

to do any service or maintenance.
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.

11
Cut or cracked power cords must be replaced. (Never operate a pump with a
cut, cracked or damaged power cord.)
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. 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.

SEAL MINDER® - THERMAL MOTOR SENSOR SWITCH
Seal Minder:
Also known as a seal failure circuit (or moisture detection circuit) is designed to inform the pump
operator that there is moisture within the oil chamber. This early warning can allow the operator to
schedule repair & inspection on the pump. The Seal Minder sensor probe is inside the oil chamber.
(The oil chamber houses the mechanical seals that are cooled & lubricated by oil). The Seal Minder,
when properly connected to a control panel, can help indicate seal failure. The Seal Minder cord
requires a seal fail circuit in control panel for warning signal.
Along, with the Seal Minder, the XP-JX Series pumps also feature thermal temperature sensor
switches that are imbedded into the motor stator windings. Two switches are imbedded into the stator
windings and wired in series. The leads are connected to the pump control panel through the sensor
cable. If the windings would see a temperature above 300 degrees F, then the switch(s) would open
and cut power to the pump. Once the temperature dropped below 300 degrees F, the switch(s) would
reset, and the pump would be returned to a state of operation. This feature is designed to prevent
damage to the stator winding and allow for longer pump life.
The sensor cable consists of four leads, two are connected to the Seal Minder, and two are
connected to the thermal sensor switches located in the stator windings. These four leads run to the
pump control panel and connect to the proper connections points for seal alarm and thermal cut off.
The G2(Green) and K(Red) wires are for the Seal Minder connections and the thermal sensors will
be connected to the m(White) and N(Black) wires. The three phase automatic wiring diagram shown
earlier in the manual will give a guide to the connections in the control panel. The manual for the
control panel should be consulted for the exact connections.
The sensor cable with Seal Minder and thermal sensor switch connections is standard on all XP-JX
Series pumps. The proper replacement part can be found parts list found in this manual. BJM Pumps,
can supply a control with the Seal Minder and Thermal sensor switch option. Separate stand alone
Seal Minder alarm panels are also available. Consult your BJM Pumps representative for part
numbers and ordering details. BJM Pumps requires the Seal Minder and thermal sensor
switches be used. Failure to connect or misuse of these devices will void warranty.
