PUMP INSTALLATION
R & RX Series pumps have been evaluated for use with water or water based solutions.
Please contact the manufacturer for additional information.
Risk of electric shock. Pump models; R100, R250, R400,
R400D, R400P, R750 & RX750 (115v) are supplied with a grounding conductor and
grounding-type attachment plug. Pump models; R1500, R15, R08, RX08SS & RX15SS
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, R & RX 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.
As a general rule, R and RX Series top 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 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 R & RX 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.
Models R100, R250, R400, and R400D are provided with a 33’ (10 m) power cord and
models R750, RX750SS R1500, RX1500SS, R1520, R1530, R08, RX08SS, R15, &
RX15SS, are supplied with a 50’ (15m) power cord. 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. 230 and 460 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.

10
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).
Typical 3 phase manual control 1
TYPICAL AUTOMATIC DEWATERING INSTALLATION
NOTE: Maximum recommended starts should not exceed 10 times per hour.
AUTOMATIC OPERATION
Float switches (wired into the pump motor or piggy-back style) are available from the
factory as an option.

11
Note: 230V & 460V pumps do not have a plug installed.
Three phase pumps need a separate control box with float(s) for automatic
operation.
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
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 has been evaluated for use with water or water based solutions. Please
contact the manufacturer for additional information.
SINGLE PHASE WIRING INSTRUCTIONS

12
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,
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 cord 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 cord 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 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.
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
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.
