PUMP INSTALLATION

LWA Series pumps have been evaluated for use with water or water based solutions.

Please contact the manufacturer for additional information.

Risk of electric shock. All LWA Pump models; 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 or terminal box
control.

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, LWA 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 www.bjmpumps.com or by
calling BJM Pumps, LLC at 860-399-5937. As a general rule, LWA 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 the 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 LWA 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.

LWA models are provided with a 50’ (10 m) power cord. NEVER splice the power cable
due to safety and warranty considerations. Always keep the power supply connection
end dry.

Note: 230V, single phase and 230V, 460V & 575V three phase units do not have a
plug and have to be provided separately or connection made to a proper
termination control box.

Typical 3 phase manual control 1

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: Attach the proper plug or connect directly to the power source or
control box. Check the direction of the rotation on 3 phase models. Tilt the pump and
start it. It should twist in the opposite direction of the arrow (on pump). It is

9

recommended that a Ground Fault Interrupter (GFI) type receptacle (or equivalent) be
used.

STOPPING

To stop the pump (manual and automatic mode), 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.

All LWA Pumps require a separate control box with float(s) for automatic
operation.

10

STOPPING

To stop the pump (manual and automatic mode), 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.

SINGLE & 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.

11

Installation and checking of electrical circuits and hardware should
be performed by a qualified licensed electrician.

To automatically operate a non-automatic LWA 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.

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 properly. LWA three phase models are supplied with two
grounding wires; one green for grounding to the panel; the other is orange and is to be
used for grounding check systems or can be also connected to the grounding point on
the control. Once connections are validated, momentarily energize the pump, observing

12

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.

LWA pumps have integral motor overload protection. It is recommended that all LWA
pumps use 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.

Service should only be performed by a qualified electrician.

MAINTAINING YOUR PUMP

 Pump should be disconnected from the electric power supply before proceeding

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.
 Cut or cracked power cords must be replaced. (Never operate a pump with a

cut, cracked or damaged power cord.)

 Seal oil should be checked once per year.
 Maintenance should always be done when taking a pump out of service before

storage.

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.

4) Inspect power cable. Make sure that it is free of nicks or cuts.

14

CHANGING SEAL OIL

Checking the seal chamber by following step one of the disassembly/assembly
procedures listed below. To change the seal chamber oil, drain the oil by removing drain
plug (55). Replace with the proper amount of ISO 32 NSF Food Grade Mineral Oil. Note
that a 10-15% air gap should be maintained in the seal chamber to allow for heat
expansion.

DISASSEMBLY/ASSEMBLY PROCEDURE FOR LWA TO REVIEW/REPLACE THE

MECHANICAL SEAL

1. Remove drain plug (55) from the seal housing (26) and take a sample of the oil. If
the oil is clear and shows no signs of water, then replace the drain plug. No
further inspection or disassembly is necessary until the next service period is
reached.

2. If the oil is milky and shows signs of water and/or other contaminants, then the
mechanical seal should be replaced. Proceed with draining the oil into a catch
basin for proper disposal.

3. Remove the suction strainer/stand (31) from the bottom of the pump by removing
the four retaining cap screws.

4. Remove the suction/wear plate (28) and O-Ring (47) by removing the four cap
screws that retain this.

5. Remove the agitator (39) by turning the agitator counter clockwise to the shaft. If
the agitator is difficult to turn, a plastic mallet or hammer and block of wood can
be used to strike against the agitator blades to break it loose from the shaft.

6. Remove the retaining nut by holding the impeller or shaft. Not do not damage the
shaft.

7. Remove the impeller (27) by sliding it off of the shaft with the shaft key (46). Take
note of any shims that are placed behind the impeller, these will need to be
reinstalled during assembly.

8. Remove the seal housing (26) by removing the four retaining cap screws. Note
that some residual oil will be found in the chamber.

9. Once the seal housing has been removed, remove all of the old seal parts. This
will require the removal of the stationary seal clamping ring and retaining screws.

10. Clean all parts and inspect for any damage. It is recommended that O-Rings and
lip seals be replaced when replacing the mechanical seal assembly (21).

11. Lubricate the cup of the stationary seal with a light amount of the Shell FM32 oil.
Using a pushing tool (PVC pipe), press the stationary seal into the pocket.
Repeat this step for both the upper and lower stationary seal.

15

12. Lubricate the lip seal (25) with oil, and press this into the bore on the opposite
side of the lower stationary seal, using the proper pressing tool.

13. Lubricate the shaft with a light coating of Shell FM32 oil. Using a pushing tool,
press the rotating element for the upper seal onto the shaft and down to the point
of contact with the stationary seal. Add the spring. Re-lubricate the shaft with a
light amount of oil and install the lower rotating element onto the shaft using a
pushing tool.

14. With all O-Rings in place, replace the seal housing and retain with the four cap
screws.

15. At this time the seal chamber should be able to be air checked. With the proper
gauge set up, apply 10 PSIG (do not add more that 10 PSIG of air pressure). No
pressure drop should be seen in five minutes under air pressure. The shaft
should be rotated a few times during this testing to insure that the mechanical
seals are operating properly.

16. Fill the seal oil chamber with the proper amount of Shell FM 32 NSF approved
oil. Note that a 10-15% air gap should be maintained in the seal chamber to allow
for heat expansion.

17. The impeller (27) with shims and the shaft key (46) can be placed onto the shaft
and secured with the retaining nut and lock washer.

18. The suction wear plate (28), agitator (39) and suction strainer/stand can be
replaced and tightened down properly.
