Note: The stator on this model is oil filled. This needs to be changed annually
when the seal oil is changed. With the power cable entry removed, fill the motor
chamber with oil to a level that insures the oil is covering the motor windings by
½”, and that will be above the upper bearing. Do not overfill, an air gap of 10-15%
must be maintained for heat expansion.
PUMP INSTALLATION
J-F & JX-F Series pumps have been evaluated for use with water or water based
solutions. Please contact the manufacturer for additional information.
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.

8
POSITIONING THE PUMP
BJM Pumps, J-F & JX-F Series pumps are designed to operate fully submerged. Data
sheets can be obtained online at HHUUwww.bjmpumps.comUUHH or by calling BJM Pumps, LLC
at 860-399-5937.
Do not run pump dry.
Pump liquid should not exceed a maximum temperature of 200°F (93°C).
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 J-F & JX-F 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.

9
PUMP ROTATION
If wired properly to the control, the single phase BJM Pumps J-F and JX-F Series pump
should operate with the correct pumping rotation. Verification is recommended prior to
installing into the sump basin.
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.

10
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 may result.
NOTE: Maximum recommended starts should not exceed 10 times per hour.
All J-F & JX-F models are provided with a 50’ (15m) power cable. NEVERUU splice the
power cable due to safety and warranty considerations. Always keep the lead end dry.
Note: The single phase 115V and 230V high temperature pumps are designed to be
connected directly to a proper pump control and cannot be directly plugged into a power
outlet.
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.
The BJM Pumps, J-F and JX-F series pumps require a special control that contains the
starting components, thermal sensor and Seal Minder connections. These pumps
cannot be directly connected to a power source.

11
TYPICAL AUTOMATIC DEWATERING INSTALLATION
NOTE: Maximum recommended starts should not exceed 10 times per hour.
STOPPING
To stop the pump (manual and automatic mode), turn the pump off at the control, turn
off the breaker, and/or turn the power source off (generator).
CONTROL PANELS CONNECTION OPTIONS
Use with approved motor control that matches motor input in full
load amperes. “UTILLISER UN DÉMARREAR APPROUVÉ CONVENANT AU
COURANT Á PLEINE CHARGE DU MOTEUR.”
BJM Pumps submersible pumps have been evaluated for use with water or water
based solutions. Please contact the manufacturer for additional information.
FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP
