pumps are designed to pump corrosive liquids in concentrations chemically
compatible with 316SS and FKM. The R & RX Series pumps are not explosion­proof. They are not designed to pump volatile or flammable liquids.

Note: Consult chemical resistance chart for compatibility between pump
materials and liquid before operating pump.

If you have any questions regarding the inspection, disassembly, assembly or testing
please contact your BJM Pumps distributor, or BJM Pumps, LLC.

SAFETY

Pump installations are seldom identical. Each installation and application can vary due
to many different factors. It is the owner/service mechanics responsibility to repair,
service, and test to ensure that the pump integrity is not compromised according to this
manual.

Risk of electric shock – this pump has not been investigated for use

in swimming pool areas.

Do not pump flammable, inflammable or volatile liquids. Death

or serious injury will result.

Before attempting to open or service the pump:

1) Familiarize yourself with this manual.

2) Unplug or disconnect the pump power cable to ensure that the pump will remain

inoperative.

3) Allow the pump to cool if overheated.

Do not operate the pump with a worn or damaged electric power

cable. Death or serious injury could occur.

Never attempt to alter the length or repair any power cable with a
splice. The pump motor and pump motor and cable must be completely waterproof.
Damage to the pump or personal injury may result from alterations.

After the pump has been installed, make sure that the pump and all
piping are secure before operation.

Do not lift the pump by the power cable piping or discharge hose.
Attach proper lifting equipment to the lifting handle (or lifting rings) fitted to the pump. Do
not suspend the pump by the power cable.

Obtain the services of a qualified electrician to troubleshoot, test
and/or service the electrical components of this pump.

Pumps and related equipment must be installed and operated

according to all national, local and industry standards.

INSPECTION

Review all safety information before servicing pump.

The following are recommended installation practices/procedures for the pump. If there
are questions in regards to your specific application, contact your local BJM Pumps
distributor or BJM Pumps, LLC.

PRE-INSTALLATION INSPECTION

1) Check the pump for damage that may have occurred during shipment.

2) Inspect the pump for any cracks, dents, damaged threads, etc.

3) Check power cord for any cuts or damage.

4) Check for, and tighten any hardware that appears loose.

5) Carefully read all tags, decals and markings on the pump.

If anything appears to be abnormal, contact your BJM Pumps distributor or BJM
Pumps, LLC. If damaged, the pump may need to be repaired before use. Do not install
or use the pump until appropriate action has been taken.

Lubrication:

No additional lubrication is necessary. The shaft seal and bearings are fully lubricated
from the factory. Seal oil should be checked once per year. See table below.

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.

7

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.

8

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.

9

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 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.
