Do not wear loose apparel that may become entangled in the impeller or other moving parts.
GENERAL INFORMATION. THE “MS” SERIES OF MODY'S SUBMERSIBLE SEWAGE PUMPS ARE PRIMARILY DESIGNED FOR HANDLING SEWAGE, SLUDGE, SLURRIES, WASTEWATER AND LIQUID MANURE. THEY CAN ALSO BE USED FOR HANDLING STORMWATER DRAINAGE WITH HIGH SOLIDS CONTENT. THE SERVICE LIFE OF A SUBMERSIBLE PUMP PRIMARILY HINGES ON TWO ASPECTS: THE DEPENDABILITY OF THE SEALING SYSTEM AND THE WEAR RESISTANCE OF THE PUMP ITSELF.
LOWERED INADVERTENTLY BY MEANS OF THE CABLE. COMPLETE DETAILS OF THE CABLE GLAND ASSEMBLY ARE SHOWN IN THE DRAWING. G] ELECTRICAL INFORMATION: MOTORS ARE DESIGNED TO OPERATE ON SINGLE VOLTAGE AND FREQUENCY. MAXIMUM DEVIATION IN VOLTAGE ALLOWED IS -/+ 6% AND FREQUENCY -/+ 3%. CHECK NAME PLATE FOR OPERATING VOLTAGE AND FREQUENCY. 230/460V DUAL WIRED MOTORS STANDARD IN NORTH AMERICA. DESIGN PARAMETERS : • • • • • LOWEST LIQUID LEVEL SHOULD BE 0.2 MTRS (8”) ABOVE PUMP CASING.

MOTOR PROTECTION IT IS ESSENTIAL THAT THE PUMP BE USED WITH A STARTER AND PREFERABLY A PANEL BOARD. PANEL BOARDS INCORPORATING ALL PROTECTIVE DEVICES ARE AVAILABLE WITH US. THE FULL LOAD AMPERE RATINGS ARE AS PER TABLE BELOW. THE OVERLOAD RELAY IN THE STARTER SHOULD BE CHOSEN ACCORDINGLY AND AMPERES SET AT THE FULL LOAD SETTING FOR THE PARTICULAR MODEL OF THE PUMP. (DETAILS BELOW ARE FOR 230/460 VOLT PUMPS. CHECK FULL LOAD AMPERES FOR DIFFERENT VOLTAGES ON PUMP NAME PLATE) MODEL MS 252 FULL LOAD AMPERES.
SEAL PROBE SENSOR OPTION ALL MODY SEWAGE SUBMERSIBLES (MS RANGE) INCORPORATE A MOISTURE SENSOR IN THE SEAL HOUSING. A PROBE INSULATED FROM THE PUMP BODY IS INSTALLED IN THIS CHAMBER AND IS ENERGIZED USING A 12V SUPPLY FROM A RELAY LIKE THE ABB LLC4. IN THE EVENT OF LOWER SEAL WEAR THE PUMPED FLUID ENTERS THE SEAL HOUSING CONTAMINATING THE OIL AND CHANGING THE ELECTRICAL RESISTANCE OF THE FLUID.
LLC41A01 06.04.02 Description The LLC4 combines resistance sensing circuitry with solid state timing to provide single probe level maintenance. On adjustable units, the sensitivity adjustment allows accurate level sensing while ignoring foaming agents and floating debris. Transformer isolated 12 V AC is provided at the probe to prevent electrolysis. A trickle current of less than 1 mA determines the presence or absence of liquid between the probe and common.
Liquid Level Control Application Notes Dual Probe Level Control The dual probe input LLC’s are designed to maintain the high or low level of a liquid within the containment tank. Figure 3 is an example of a water well reservoir application. Using an LLC2 Series open board design or the LLC5 series 8 pin plug-in (with the ‘B’ fill logic), we will be able to maintain a precise level within the holding vessel.
GENERAL OVERHAUL AND OIL CHECK. (THIS APPLIES TO BOTH MODELS) TO CARRY OUT A GENERAL OVERHAUL, IT IS ESSENTIAL THAT A COMPLETE SET OF TOOLS BE AVAILABLE AS PER TOOL KIT LIST. (LIST IS AVAILABLE AT THE END OF THE MANUAL). DIS-ASSEMBLY(REFER DRG.NO.MS/859/00 • IT IS MANDATORY THAT ALL "O" RINGS BE REPLACED WHENEVER A PUMP IS OVERHAULED OR DISMANTLED. UNDER NO CIRCUMSTANCES SHOULD OLD "O" RINGS BE USED, EVEN IF THEY SEEM O.K. BE CAREFUL NOT TO SCRATCH SEALING SURFACES.
RE- ASSEMBLY OF THE PUMPSET. THE PUMP CAN BE RE- ASSEMBLED BY REVERSING THE ABOVE PROCEDURE. PLEASE HOWEVER NOTE THE FOLLOWING: • • • ALWAYS REPLACE ELASTOMER ELEMENTS. REPLACE LOCK WASHER DURING RE –ASSEMBLY. CAREFULLY READ THE SEAL ASSEMBLY INSTALLATION INSTRUCTIONS PAGE. OIL SPECIFICATIONS A) EXXON UNIVOLT 61 B) SHELL TELLUS 29. C) CHEVRON SUPERLA 10 FDA APPROVED PLEASE NOTE THE SEAL CHAMBER CONTAINS APPROX. 2.5 LITRES OF OIL.
