1. Most accidents can be avoided by using COMMON SENSE.

2. Please read the operation and maintenance instruction manual supplied with the
pump. If you did not receive one, please call your local distributor before pump
installation.

3. Do not wear loose apparel that may become entangled in the impeller or other
moving parts.

4. Always use appropriate safety equipment, such as safety glasses, when working on
the pump or piping.

5. Pumps build up heat and pressure during operation-allow time for pumps to cool
before handling or servicing.

6. Only qualified service personnel should install, operate and repair pump.

7. Keep clear of suction and discharge openings. DO NOT insert fingers in pump with
power connected.

8. Do not pump flammable or hazardous materials (gasoline, acids, alkalis, etc.)

9. Do not block or restrict discharge hose, as it may whip or burst catastrophically
under pressure.

10. Make sure lifting handles/hooks are securely fastened each time before lifting.

11. Do not lift pump by the power cord under any circumstances.

12. Do not exceed manufacturer's recommendation for optimum performance, as this
could cause the motor/pump to overheat and lead to premature wear or failure.

13. Secure the pump in its operating position so it does not tip over, fall or slide.

14. Keep away from impeller when power is connected.

15. Submersible Pumps are not approved for use in swimming pools, recreational water
installations, decorative fountains or any installation where human contact with the
pumped fluid is common.

16. Do not operate pump without adequate protection and safety devices in place.

17. Always replace safety devices that have been removed during service or repair.

18. To reduce risk of electrical shock, pump must be properly grounded in accordance
with the National Electric Code and all applicable state and local codes and
ordinances.

19. To reduce risk of electrical shock, always disconnect the pump from the power

source before handling or servicing.

20. Any wiring of pumps should be performed by a qualified electrician.

21. Never operate a pump with a power cord that has frayed or brittle insulation.

22. Cable should be protected at all times to avoid punctures, cuts, and

abrasions - inspect frequently.

23. Never handle connected - "hot" power cords with wet hands.

24. Never operate a pump with a plug-in type power cord without a ground fault circuit
interrupter, adequate overload and short circuit protection.

IMPORTANT !!! MODY Pumps Inc. is not responsible for losses, injury, or death resulting

GENERAL INFORMATION.

THE

“mody” NC-M SERIES LINE OF SUBMERSIBLE PUMPS ARE PRIMARILY DESIGNED FOR

HANDLING SLUDGE AND SOLIDS. THEY CAN ALSO BE USED FOR HANDLING WASTE WATER, FLY
ASH, CERAMIC SLIP AND IN OTHER ALLIED APPLICATIONS WHERE THE CONCENTRATION OF
SUSPENDED SOLIDS IS HIGH.

THE SERVICE LIFE OF A SUBMERSIBLE PUMP DEPENDS MAINLY ON TWO THINGS: THE
DEPENDABILITY OF THE SEALING SYSTEM AND THE WEAR RESISTANCE OF THE PUMP ITSELF.

IN THE NC-M SERIES PUMPS, THE WEAR PLATE IS RUBBERLINED WHILE THE VOLUTE AND
IMPELLER ARE MADE OF CAST STAINLESS STEEL. THE IMPELLER IS A RECESSED VORTEX
DESIGN THAT ALLOWS THE PUMP TO HANDLE 2 1/2" SPHERICAL SOLIDS. ALL LARGE
PARTICLES ARE SUCKED IN USING THE VORTEX CREATED BY THE IMPELLER AND PASS OUT
DIRECTLY THROUGH THE DISCHARGE.

ALL MODELS HAVE BUILT-IN THERMAL PROTECTION, WHICH CAN BE AUGMENTED WITH AN
OVERCURRENT RELAY. IT IS HOWEVER RECOMMENDED THAT IRRESPECTIVE OF TYPE OF PUMP,

ADEQUATE MOTOR PROTECTION SWITCHGEAR SHOULD BE USED AT THE INSTALLATION. WE
STRONGLY RECOMMEND THE USE OF SUITABLE CONTROL PANELS WHICH ARE AVAILABLE FROM
US INCORPORATING ALL REQUIRED PROTECTION.

IT IS IN THE INTEREST OF THE USER THAT HE GO THROUGH THIS MANUAL IN DETAIL
PRIOR TO USING THE PUMP. THIS MANUAL WILL HELP HIM UNDERSTAND THE
CONSTRUCTIONAL FEATURES AND TO OBTAIN TROUBLE FREE SERVICE FROM THE PUMP.

TECHNICAL DESCRIPTION

THE PUMPSET IS IN A MODULAR CONSTRUCTION ENSURING EASY AND SIMPLE
SERVICEABILITY. THE MAJOR DESIGN FEATURES ARE AS UNDER:

A] THERMAL PROTECTION: SEE UNDER "MOTOR PROTECTION"

B] THE MOTOR: A RUGGED ALUMINUM DIE CAST ROTOR, DYNAMICALLY BALANCED TO GRADE

2.5 ACCURACY OF ISO 942. A STAINLESS STEEL SHAFT RUNNING IN TWO DEEP GROOVE
BALL BEARINGS. INSULATION CLASS "F" (155 DEGREES CELSIUS). END WINDINGS DULY
EPOXY COATED TO PREVENT DETERIORATION OF INSULATION EVEN IN EXTREMELY HUMID
CONDITIONS. WINDING WIRE IS DUAL COATED SUITABLE FOR "H" CLASS INSULATION.

C] THE SEAL CHAMBER: THE HEART OF THE "MODY" PUMP. DUAL MECHANICAL SEALS,
TUNGSTEN CARBIDE V/S TUNGSTEN CARBIDE SEAL FACES (LOWER SEAL) AND TUNGSTEN
CARBIDE V/S TUNGSTEN CARBIDE (UPPER SEAL). SECONDARY SEALS OF HNBR RUBBER AND
METAL PARTS IN STAINLESS STEEL, RUNNING IN AN OIL BATH, ENCLOSED IN A PRESSURE
COMPENSATING RUBBER BAG - CREATES THE ULTIMATE SEAL SOLUTION. THE DESIGN
OPTIMIZES SEAL LIFE AND ALLOWS FOR SIX MONTHLY (2500 HRS) SERVICE INTERVALS.

D] BEARINGS: SINGLE ROW DEEP GROOVE BALL BEARING (UPPER), DOUBLE ROW ANGULAR
CONTACT BEARING (LOWER) SEALED FOR LIFE WITH A SPECIAL HIGH TEMPERATURE BEARING
GREASE REQUIRING NO PERIODIC MAINTENANCE WHATSOEVER.

E] THE HYDRAULIC ELEMENTS : A RECESSED VORTEX STAINLESS STEEL IMPELLER
(AVAILABLE IN CORROSION RESISTANT 304 SS OR IN ABRASION RESISTANT 410 HARDENED
SS RUNNING AGAINST A RUBBERLINED WEAR PLATE. THE VOLUTE IS STAINLESS STEEL OF
AISI 304 QUALITY, DESIGNED FOR LARGE SOLID HANDLING CAPACITY OF 2 1/2"

.

F] CABLE GLAND ASSEMBLY: THE PUMP IS SUPPLIED WITH 50 FEET CABLE AS STANDARD.
THE CABLE IS A 4 CORE EPR SHEATHED AND INSULATED CONFORMING TO INT'L STD. THE
CABLE IS WATERPROOF AND CAN BE COMPLETELY SUBMERGED IN WATER. THE CABLE IS
TERMINATED IN THE PUMP AT THE CABLE GLAND. THE GLAND ASSEMBLY SEALS THE CABLE
ON THE OUTSIDE SHEATH. A WATER DAM ARRANGEMENT IS ALSO PROVIDED WHICH SEALS THE
INDIVIDUAL CORES OF THE CABLE. THIS FEATURE IS UNIQUE AND IS ESSENTIAL TO
PREVENT WATER SEEPING THROUGH THE CORES OF THE CABLE INTO THE TERMINAL CHAMBER
IN THE EVENT OF A CUT CABLE. THE CABLE IS ALSO SHEATHED FOR THE FIRST ONE METER
BY MEANS OF A CABLE GRIP MADE OF STAINLESS STEEL. THIS IS ESSENTIAL TO ENSURE
THAT THERE IS NO UNDUE STRAIN ON THE CABLE IF THE PUMP IS PULLED OR LOWERED
INADVERTENTLY BY MEANS OF THE CABLE. COMPLETE DETAILS OF THE CABLE GLAND
ASSEMBLY ARE SHOWN IN THE DRAWING.

G] ELECTRICAL INFORMATION: MOTORS ARE TYPICALLY DESIGNED TO OPERATE ON
230/460V AT 60 HZ. EXPORT DESTINED PUMPS ARE PREWIRED FOR SINGLE VOLTAGE AND
FREQUENCY. MAXIMUM DEVIATION IN VOLTAGE ALLOWED IS -/+ 6% AND FREQUENCY -/+ 3%.
CHECK NAME PLATE FOR OPERATING VOLTAGE AND FREQUENCY.

INSTALLATION.

• CHECK THAT THE SITE VOLTAGE CORRESPONDS WITH THAT OF THE PUMP.

• CHECK THAT FUSES ARE INTACT.

• USE SHORTEST POSSIBLE HOSE IN RECOMMENDED DIMENSION. AVOID SHARP BENDS,

CREASES, AND CONTRACTIONS.

• THE MAXIMUM SUBMERGENCE RECOMMENDED IS 50 FEET.

• THE SPECIFIC GRAVITY OF THE PUMPED FLUID SHOULD NOT EXCEED 1.1.

• NEVER LIFT OR PULL THE PUMP BY MEANS OF THE CABLE. SUSPEND THE PUMP BY A

ROPE OR PREFERABLY PLACE IT ON A SOLID BASE.

• WIRE THE PUMP TO THE MAINS CORRECTLY. ALWAYS USE A STARTER OR A PANEL BOARD.
SEE INSTRUCTIONS UNDER "MOTOR PROTECTION" BELOW.

• AT THE STARTING MOMENT, THE PUMP SHALL MAKE A KICK, WHICH IS OPPOSITE TO THE
DIRECTION OF ROTATION OF THE IMPELLER. SHIFT TWO PHASES IN THE POWER
CONNECTION IF THE KICK IS IN THE WRONG DIRECTION. THE CORRECT DIRECTION IS
INDICATED ON THE PUMP COVER AT THE TOP OF THE PUMP.

• CHECK LEVEL AND CONDITION OF THE OIL AT SERVICE EVERY SIX MONTHS. IF THE OIL
IS EMULSIFIED BY WATER THE SEALS MUST BE REPLACED.

• THE SHAFT SEAL SHOULD BE CHECKED FOR WEAR EVERY 2500 HRS. OF OPERATION. IF
SEAL FACES SHOW ANY SIGNS OF WEAR, THEY SHOULD BE REPLACED. REFER TO PAGE 5
FOR SERVICING THE PUMP SEALS.
