ELECTRICAL RISKS

Pumps with a single seal are supplied with a grounding conductor and grounding-type attachment plug on the power cord. To reduce the risk of electric shock:



Be certain that it is connected only to a properly grounded, grounding-type receptacle.



DO NOT cut off ground pin or use an adapter fitting.



DO NOT use an extension cord with this pump.



Entire plug may be cut off if a control panel is used.



en wiring this pump follow all local electrical and safety codes and ordinances as well as the most recent National Electric Code (NEC-ANSI/NFPA 70).

All pumps have a GROUND WIRE that is connected to a screw in the metal motor housing. This wire goes to the receptacle or control box which must be connected to a good outside GROUND such as a metal water pipe or GROUND STAKE driven

at least 8 feet into theground.

23822A278 (02-13-20)

DESCRIPTION

Myers ME and MW series pumps are available in both a single seal as well as a double seal design with leak detector. The ME50-ME150 models are designed for effluent dosing, Septic Tank Effluent Pumping (S.T.E.P.) or normal sump and general dewatering applications where higher pressure is required. These units are designed to handle ¾” spherical solids. The MWH50-MW200 models are designed for raw sewage applications and can pass 2” spherical solids. These units can also be used for sump and general dewatering applications where larger solids capabilities are required.

When used in effluent dosing or S.T.E.P. applications, the pump must be installed in a separate tank or compartment at the discharger side of the septic tank. Never install pump in tank

where sludgecollects.

These pumps are available in single phase and three phase, and either in single seal or double seal with seal leak detector. All three phase units, all double seal units and all duplex installations must be used with a control box. All power cords and seal leak detector cords are 20 feet long.

The ME model impellers are enclosed two vane type to handle ¾” spherical solids and are available made of engineered thermoplastic or optional naval bronze. All pumps have a 2” NPT discharge tapping.

single phase pumps can be made automatic by attaching MFLC or MFS controls to the pump. These switches have a fixed draw off level of 8 to 10 inches and can be used up to 1 HP. For higher horsepower ratings two mercury switches (or SMNO) controls with a magnetic starter can be used. Simplex systems may also use on/off pilot mercur y control switches (when permitted by code) with control box and magnetic starter. The ALC and AWS-1 controls can be used for simplex single phase pumps with ratings up to 2 HP. All duplex systems must use pilot mercur y control switches with control box and magnetic starters.

Plug-in cords can be used on all the single phase pumps with a single seal (does not have a seal leak detector). This cord has a GROUND pin that plugs into a grounded receptacle. The grounded receptacle cannot be used in the wet sump or basin

due to DANGER of current leakage. Sealed junction boxes must

be used in wet sumps or basins to make connections to motor

cord. The AWS-1 control also acts as a sealed junction box for

connecting power cord to pump cord.

DOUBLE SEAL PUMPS

All pumps in this series “ME—D” or “MW—D” have two seals with an oil chamber between the seals so that the seal faces of both the lower and upper seals are oil lubricated for longer life and greater protection against water leaking into the motor windings. These double seal units are all made with a seal leak de tector.

The MW model impellers are enclosed two vane non-clog style, designed to handle 2” spherical solids. The MW pumps are available with standard cast iron or optional naval bronze impellers.

These pumps are NOT for use in swimming pools orfountains.

AIR LOCKING

A sump pump is said to be air locked if water traps air in the pump and it cannot get out, thus preventing the pump from operating.

In installation of this type a 1/8” hole should be drilled in the

discharge pipe just above the pump discharge and a check valve

should be installed 12 to 18 inches above pump discharge. Do not put check valve directly into pump discharge opening - follow local code.

PACKAGING

Each pump is packaged separately in a carton marked with a catalog number and the Myers engineering number.

LEVEL CONTROLS

All pumps must use sealed level control switches for automatic operation. MLC and MFLC controls have sealed switches that are 1 HP rated at 230 volts. ALC and AWS-1 controls have sealed mechanical switches that are rated 2 HP at 230 volts.Simplex

The leak detector in the oil seal chamber detects any water leakage into the chamber and turns on a red signal light in the control panel. Pumps should be removed from the sump and seals replaced after the seal light shows in the panel. Control panels must be used for pumps having the seal leak detectors, and seal leak detectors must be wired as illustrated

in theseinstructions.

D ESIGN OF PRESSURE SEWER SYSTEMS

MYERS has available complete computer SOFTWARE for designing PRESSURE SEWER SYSTEMS. This gives pipe sizes to use and gives exact flow from any pump or group of pumps in the system when operating simultaneously. This design DISK for IBM

or COMPATIBLE computers is available to engineers onrequest.

23822A278 (02-13-20)

INSTALLATION

MOTOR TYPE

Motors are ¾ frame, 1/2 – 2HP single or three phase, 60 Hertz, 3450 R.P.M. with class B insulation. All single phase motors are permanent split-capacitor (PSC) type with built-in on-winding overload protection and do not require a start switch or start relay. The three phase pump motors require a magnetic starter with 3 leg overload protection. All motors have upper and lower ball bearings and all are oil-cooled and lubricated.

Breathing hazard. Basin or tank must be vented in accordance with local plumbing codes. These pumps are not designed for and CANNOT be installed in locations classified as hazardous in accordance with the National Electric Code ANSI/ NFPA 70.



Never enter pump chamber after sewage or effluent has been in basin. Sewage water can give off methane, hydrogen sulfide and other gases which are highly poisonous.

Myers recommends installing ME series effluent pumps with a quick removal system. The quick removal system may be a union or quick-release coupling if the pipe or discharge hose is within reach from the surface, or a rail system type quick disconnect on deeper installations. See installation drawings for

suggestedinstallation.

The dosing tank or pumping chamber must be constructed of corrosion resistant materials and must be capable of withstanding all anticipated internal and external loads. It also must not allow infiltration or exfiltration. The tank must have provisions for anti-buoyancy. Access holes or covers must be of adequate size and be accessible from the surface to allow for installation and maintenance of the system. Access covers must be lockable or heavy enough to prevent easy access by unauthorized personnel. The pumping chamber holding capacity should be selected to allow for emergency conditions.

The discharge pipe must be the same size as the pump discharge (2 inches) or larger. In order to insure sufficient fluid velocity to prevent any residual solids from collecting in the discharge pipe, it is recommended that a minimum flow of 2 feet per second be maintained. (21 GPM through 2” pipe and 46 GPM through 3” pipe). It is recommended that PVC or equal pipe is used for corrosion resistance.

A full flow (ball or gate) shut off valve must be installed to prevent back flow of effluent if the pump must be removed for service. A check valve must be installed on pressure sewer systems and on other systems where conditions allow to prevent backflow and to reduce wear on the pump system.

A high water alarm must be installed on a separate circuit from the pump circuit. The alarm should have the ability to be tested for proper operation.

S PECIAL INSTRUCTIONS FOR THREE PHASE PUMPS

1. Myers recommends three phase pumps to be installed by qualified personnel.

strain relief. Do not connect conduit topump.

3. Three phase pumps are always installed with control boxes having magnetic starters with 3 leg overload protection. DO NOT TRY TO RUN THREE PHASE PUMPS DIRECTLY ACROSS THE LINE.

4. To Connect Pump: Run wire from pump to the bottom

of control box or appropriate junction box suitable for

enclosing splice connections. A hole must be cut into the control box for the wires. With power to control box off, connect green (ground) line to ground lug. Connect black (power) wires to power lead terminals.Note: for a typical CE style control box, these terminals are marked M1, M2 and M3. Make sure that all wires are inside control box and not in a position to be pinched or shorted when the door is closed.

Risk of electric shock. Do not remove cord and

MAINTENANCE

BEFORE DISMANTLING PUMP FOR REPLACEMENT OF PARTS

Clean pump thoroughly. Knock off all scale and deposits. Use sandblast if possible. Submerge complete unit in dilute bleach

solution for one hour beforedisassembly.

TO REPLACE CAPACITORS ONLY

All of the single phase motors are of the permanent split capacitor type and have no relays or starting switch. They have only a starting capacitor that is in the circuit for both starting and running conditions.

1. Remove oil fill plug near the top of the motor and pour the oil out.

2. Loosen the pug nuts around the cords until they are loose enough to push the cords down inside of the motor housing.

3. Remove the four bolts from the motor housing and bump the housing with a plastic hammer to loosen. Lay the pump on its side.

4. Remove the housing carefully to be sure that enough cord is pushed into the housing to create no tension on the cords.

5. Slide motor housing up far enough to expose the capacitor and to be able to lay the housing down.

6. Disconnect wiring from capacitor and loosen capacitor clamp and slide out capacitor. Replace with new capacitor, tighten and re-connect. Wiring diagram is given in these instructions.

7. Check all wiring connectors to be sure they aresecure.

8. Be sure tetraseal gasket is in place.

9. Slide motor housing back onto pump while pulling the cords out slowly. Assemble the motor housing with the four bolts.

10. Re-assemble cord nuts. Be sure washers are seated and cords are pulled up to stop against the washers. Tighten nuts securely.

11. Put pump upright and refill motor with refined paraffinic transformer oil, ¹Shellflex™ 2210 or equivalent. DO NOT OVER FILL WITH OIL. With pump upright fill oil to bottom of oil fill tapping. Replace oil fill plug

¹ Shel l Oil Compan y, Texas

12. Be sure pump turns freely before connecting to power. Turn pump on side and turn impeller, using screwdriver in slotted shaft. Plug pump into receptacle to test operation. Pump must run quiet and free of vibration.

TO REPLACE POWER CORD AND/OR SEAL LEAK DETECTOR CORD

Remove motor housing as described above. Disconnect the push-together terminals and remove the ground screw from the

power cord if beingreplaced.

Completely unscrew cord bushing to be replaced and remove cord assembly from housing. Be sure remaining terminals are secure on the wires.

Replace with proper cord with fittings. Push cord into the motor housing far enough to make proper connections. Reconnect ground wire if replacing power cord and securely connect the wires correctly. See wiring diagram in these instructions.

Assemble cords and motor housing as described in Capacitor Replacement. Fill with oil as noted and be sure pump turns

freely before connecting topower.

T O REPLACE MOTOR STATOR AND SHELL

1. Remove motor housing as described above.

2. Disconnect all leads from power and seal leak cords and ground wire and set pump upright.

3. Loosen the four long screw holding the motor and remove slowly. If unit has seal leak probes, be sure to feed the wires through the slots as the motor is being removed.

4. Either remove previous capacitor and clamp from old motor and assemble onto new stator and shell or replace with a new capacitor and assemble the two capacitor leads per wiring diagram.

5. Position bearing spring washer on top of upper ball bearing.

6. Tighten terminal screws of seal leak probes and feed wires through the motor slots.

7. Position the “stator with shell” into place and line up screws with the bosses and tighten the (4) long screws. Extend probe wires out through the slots. Lay unit down in line with motor housing.

8. Be sure pump turns freely with screwdriver in impeller end of shaft.

9. Reconnect all terminals securely per wiringdiagram.

10. Be sure tetraseal gasket is in place.

11. Reassemble motor housing and fill with oil as noted above in capacitor replacement.

NOTICE On three phase motors always check unit for proper rotation. With pump on its side apply power by turning on, then off, quickly. Impeller must turn counter-clockwise when looking into the impeller inlet. If not, interchange any two leads in the control box.

23822A278 (02-13-20)

MAINTENANCE

SHAFT SEAL REPLACEMENT

1. Remove plugs in motor housing and in seal housing (for double seal units) and drain oil.

2. Remove four bolts holding the volute case and bump with a

plastic hammer to loosen and removecase.

3. Hold impeller and unscrew impeller locking screw. Turn counterclockwise to loosen.

4. Pry off seal bellows and ceramic seat. Break seats if necessary to get out since they must be replaced with new parts.

5. NEVER USE OLD SEAL PARTS - USE ONLY COMPLETELY NEW SEALS. (Do not use seal spring retainer plate on single seal pump or lower seal of double seal pump.)

6. For single seal pumps or if only replacing the lower seal of a double seal pump, it is not necessary to disassemble further. On a double seal pump, it is not necessary to drain

oil out of the motor housing, just the seal housing.

10. Check HUVA cup seal in volute case inlet. If worn,replace.

11. Be sure tetraseal gasket is in position (replace if worn) and reassemble.

12. Replace oil in motor housing and seal chamber. Use only Myers submersible oil.

13. Be sure pump turns freely before connecting to power. After connecting, check for proper rotation noted under

Stator Replacement.
