GENERAL DESCRIPTION AND
APPLICATION
Myers ME and MW series pumps are available in both
a single seal design and double seal design with leak
detector. The ME33-150 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 MAIN 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 cast brass. All pumps have
a 2” NPT discharge tapping.
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 cast brass 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 below the check valve. The check valve
should be 12 to 18 inches above pump discharge. Do not
put check valve directly into pump discharge opening.
PACKAGING
Each pump is packaged separately in a carton marked
with a catalog number and 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 single phase pumps can be made automatic
by attaching MFLC or MLC 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 mercury control switches 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 mercury 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 detector.
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.
DESIGN 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.
MOTOR TYPE
Motors are ¾ frame, 1/3 – 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.

SAFETY WARNINGS
WARNING: Risk of electric shock. 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. All
double seal pumps, all duplex installations and all three
phase pumps require a control box.
When 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.
When overload current protection is provided by installer:
USE WITH APPROVED MOTOR CONTROL THAT
MATCHES MOTOR INPUT IN FULL LOAD AMPERES
WITH OVERLOAD ELEMENT(S) SELECTED OR
ADJUSTED IN ACCORDANCE WITH CONTROL
INSTRUCTIONS. (UTILISER UNDEMARREUR APPROUVE
CONVENANT AU COURANT A PLEINE CHARGE DU
MOTEUR ET DONT LES ELEMENTS THERMIQUES
SONT REGLES OU CHOISIS CONFORMEMENT AUX
INSTRUCTIONS QUI L’ACCOMPAGNENT).
When motor has built-in overload protection:
USE WITH APPROVED MOTOR CONTROL THAT
MATCHES MOTOR INPUT IN FULL LOAD AMPERES.
(UTILISER UN DEMARREUR APPROUVE CONVENANT
AU COURANT A PLEINE CHARGE DU MOTEUR).
INSTALLATION
WARNING: 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.
CAUTION: 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.
For this reason, Myers recommends installing the ME
series effluent pumps with a quick removal system.
The quick removal system may be a union or Cam-lok
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.
SPECIAL INSTRUCTIONS FOR
THREE PHASE PUMPS
(1) F.E. Myers recommends three phase pumps to be
installed by qualified personnel. CAUTION: Risk of
electric shock. Do not remove cord and strain
relief. Do not connect conduit to pump.
(2) 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.
(3) 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
con
trol 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.
(4) All three phase motors can run either direction.
ROTATION can be changed by interchanging any two
line leads at magnetic starter.
BE SURE CIRCUIT
BREAKER IS OFF BEFORE MAKING THIS CHANGE.

23833A278 8
To find if rotation is correct operate pumps and check
delivery operation. If flow and head is low (refer to
pump curves shown in this manual) the rotation is
wrong. With duplex pumps, check operation of both
pumps.
(5) All pump impellers, either single or three phase, must
turn counterclockwise when looking into pump inlet.
If uncertain of rotation, TURN OFF POWER and lift
pump from basin with cord connected and lay pump
on side so impeller can be seen. Turn on power and
start pump using hand position of H-O-A switch.
Turn on and off fast so that coast of impeller can be
seen. NEVER PUT HAND OR FINGERS ON THE
IMPELLER. Interchange any two l line leads at the
magnetic starter to change rotation.
POINTS TO CHECK IF PUMP DOES NOT RUN
OR DOES NOT RUN PROPERLY
(1) Pump does not run or start when water is up in tank.
(a) Check for blown fuse or tripper circuit breaker.
(b) Check for defective level switch.
(c)
Where control panel is used be sure H-O-A switch
is in the AUTO position. If it does not run, turn switch
to the HAND position and if the pump runs then the
trouble is in the automatic electrical system. Have an
ELECTRICIAN make electrical checks.
(d) Check f
or burned out motor. Occasionally lightning
can damage a motor even with lightning protection.
(e) Where plug-in cords are used be sure contact
blades are clean and making good contact. DO
NOT USE PLUG-IN CORDS INSIDE A SUMP OR
WET WELL.
(f) Level control ball or weight may be stuck on side
of basin. Be sure it floats freely.
(2) Pump runs but does not deliver flow.
(a) Check air lock. Start and stop pump several times;
if this does not help it may be necessary to loosen
a union in the discharge line to relieve air lock.
(b) Check valve may be installed backwards. Check
flow arrow on valve body. Check shut-off valve. It
may be closed.
(c) Check vertical elevation. It may be higher than
pump can develop. (See pump curve).
(d) Pump inlet may be plugged. Remove pump to
check.
CAUTION: ALWAYS UNPLUG POWER CORDS OR
TURN OFF ALL MAIN AND BRANCH CIRCUIT BREAKERS
BEFORE DOING ANY WORK ON THE PUMP.
If control
panel is remote from pump, disconnect lead wires to
motor so that no one can turn the circuit breaker back
on. If motor is three phase, mark the leads so they can
be replaced in the same order.
BEFORE DISMANTLING PUMP FOR
REPLACEMENT OF PARTS
Clean pump thoroughly. Knock off all scale and deposits.
Use sandblast if possible. Submerge complete unit in
Clorox solution for one hour before taking apart.
