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 "H" (180 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, 415V AT 50 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.

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.

BUILT-IN CONTROLS
THE BUILT-IN MOTOR PROTECTION OF THE PUMP AUTOMATICALLY BREAKS THE CURRENT IF
THE MOTOR IS OVERHEATED. WHEN THE CURRENT IS CUT OFF, IT IS NECESSARY TO FIND
THE CAUSE AND TAKE REMEDIAL ACTION.
OVERLOAD/OVERHEAT PROTECTION (REFER CIRCUIT DIAGRAM ABOVE)
THE CONTACTOR COIL IS COUPLED IN SERIES WITH THE BI-METALLIC SWITCHES. THE COIL
CIRCUIT IS CONNECTED BETWEEN TWO OF THE INCOMING PHASE WIRES. WHEN THE PUMP IS
CONNECTED TO THE POWER MAINS, THE COIL GETS VOLTAGE AND ATTRACTS THE CONTACT
BRIDGE. THE MOTOR STARTS AND THE PUMP BEGINS TO OPERATE. IF THE MOTOR GETS
OVERHEATED THE BI-METALLIC SWITCHES OPEN AND CUT OFF THE CURRENT TO THE COIL.
WHEN THE MOTOR HAS COOLED DOWN TO NORMAL OPERATING TEMPERATURE THE SWITCHES
CLOSE, THE CONTACTOR COIL IS AGAIN ENERGIZED AND THE PUMP RE-STARTS. IT IS
ADVISABLE TO FIND OUT THE CAUSE OF OVERHEATING IF THE PUMP TRIPS OFTEN.

SEAL PROBE (WATER-IN-OIL SENSOR)
PUMP CAN ALSO BE EQUIPPED WITH A WATER-IN-OIL SENSOR FITTED IN THE CONTACTOR
CHAMBER. A CONDUCTIVITY PROBE IS FITTED IN THE SEAL CHAMBER & MONITORS THE
CONDITION OF THE OIL. IN THE EVENT OF A CONTAMINATION OF THE LUBRICATING OIL BY
PUMPED WATER THE PROBE SENDS A SIGNAL TO THE BUILT IN SENSOR WHICH CUTS OFF
POWER TO THE MOTOR. THIS INDICATES A SEAL FAILURE OR WORN OUT SEAL AND IT IS
NECESSARY TO REPLACE THE SEALS AND FILL IN NEW OIL.
THE CONDUCTIVITY PROBE IS CONNECTED TO A 24V AC SUPPLY THROUGH A TRANSFORMER.
IN THE EVENT OF A SEAL FAILURE AND CONTAMINATION OF OIL BY WATER (APPROX. 10%)
THE PROBE GENERATES A SIGNAL, DETECTED BY A SENSOR, WHICH OPERATES A RELAY
THROUGH THE BRIDGE RECTIFIER. THIS RELAY OPERATES THE CO CONTACT WHICH OPENS
THE COIL CIRCUIT OF THE MAIN CONTACTOR AND ISOLATES THE PUMP FROM THE POWER
SUPPLY.
THE SENSOR COMPLETE WITH TRANSFORMER IS HOUSED IN A SHEET STEEL ENCLOSURE DULY
WIRED. THE ENCL. INCORPORATES AN LED AND A REMOVABLE FUSE. IN THE EVENT OF
WATER CONTAMINATION IN THE OIL THE SENSOR WILL ISOLATE THE PUMP AND THE LED
WILL LIGHT UP INDICATING THE OPERATION OF THE SENSOR. THE PUMP WILL NOT START
IN THIS CONDITION. IF YOU WOULD LIKE TO OPERATE THE PUMP, REMOVE THE FUSE AND
START THE PUMP.
WARNING: THE UNIT SHOULD NOT BE OPERATED FOR MORE THAN 10 DAYS AFTER THE SENSOR
HAS TRIPPED THE PUMP. THE PROBE OPERATION IS AN EARLY WARNING SIGNAL THAT THE
SEALS NEED REPLACEMENT --- DO NOT IGNORE THE SAME. IT IS ESSENTIAL THAT THE
SEALS BE REPLACED AND NEW OIL FILLED AS SOON AS POSSIBLE TO PREVENT FURTHER
DAMAGE TO THE UNIT. THE FUSE SHOULD BE REMOVED AND THE PUMP OPERATED IF
ABSOLUTELY NECESSARY.
IN THE EVENT OF OVERHEATING OF THE STATOR WINDING FOR ANY REASON, THE EMBEDDED
THERMAL SWITCHES WILL OPEN, CAUSING THE STARTER COIL TO DROP OUT AND ISOLATE
THE PUMP UNIT FROM THE MAINS. THESE SWITCHES DO NOT PROVIDE ANY PROTECTION IN
THE CASE OF A SHORT CIRCUIT, AND ADEQUATE H.R.C. FUSES SHOULD BE USED FOR SHORT
CIRCUIT PROTECTION.
