NOTE: The stator on this model isoilfilled. This needs to be changed annually
when the seal oilis changed. With the power cable entry removed, fill the motor
chamber with oilto 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
SK-F & SKX-F Series pumps have been evaluated for use with water or water based
solutions with some solids. Please contact the manufacturer for additional information.
The BJM Pumps®Shredder Pumps (7.5 HP and larger) are designed to
handle unscreened sewage.
Risk of electric shock. Pump models; 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.

8
BJM Pumps®SK-F &SKX-F Series pumps are designed to operate fully
submerged. Data sheets can be obtained online at www.flowsolutions.com or by
calling Industrial Flow Solutions Operating, 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 SK-F & SKX-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.
•Take stand off of pump when using slide rail. Keep stand and reattach when
transporting or handling the pump.
POSITIONING THE PUMP

9
PUMP ROTATION
If wired properly to the control, the single phase BJM Pumps®SK-F and SKX-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.
TYPICAL MANUAL WASTEWATERING INSTALLATION
NOTE: Maximum recommended starts should not exceed 10 times per hour.
All SK-F & SKX-F Models are provided with a 50’ (15 m) power cable. NEVER splice
the power cable due to safety and warranty considerations. Always keep the lead end
dry.
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® SK-F and SKX-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

Seal Minder® - Thermal Motor Sensor Switch
(For high temperature single phase pump models)
Seal Minder:
Also known as a seal failure circuit (or moisture detection circuit) isdesigned 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 arecooled & lubricated by oil). The Seal Minder,
when properly connected to a control panel,can help indicate seal failure. The Seal Minder cable
requires a seal fail circuit in control panelfor warning signal.
Along, with the Seal Minder,the Fahrenheit® Series high temperature 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. Ifthe 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 (Note on 400 models the
sensor and power are in a single cable).These four leads run to the pump control panel and connect
to the proper connections points for seal alarm and thermal cut off. The black and white wires on
750-1500 models, black with white stripes and white with black stripes on 400 models; are for the
Seal Minder connections and the thermal sensors will be connected to the yellow and red wires on
750-1500 models, yellow and red with yellow stripes on 400 models (see details on wiring diagram).
The single phase 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 isstandard on all
Fahrenheit® Series high temperature pumps (Note the 400 models have a different wire color code in
the single cable design). The cable is designed for a high temperature environment. The proper
replacement partcan be found parts list found in this manual. BJM Pumps, can supply a control with
the Seal Minder and Thermal sensor switch option. BJM Pumps requires the Seal Minder and
thermal sensor switches be used. Failure to connect or misuse of these devices will void warranty.
