GENERAL INFORMATION:
General Construction: The base and pump guide
plate on all the models are made of ASTM A536 ductile
iron (see Fig. 1). The mounting flange on all of the
models is made of ASTM A48 Class 30 cast iron. The
locating pins and all fasteners are made of 300 series
stainless steel. Gaskets are constructed of neoprene
rubber material. The elbows are constructed of ASTM
A48 Class 125 cast iron. The hazardous location/nonsparking models have 260 yellow brass sleeved onto
the locating pins and have a cast brass mounting plate
to meet the non-sparking requirements.
Lift-Out Chain: Myers offers lift-out chain packages
for each pump we manufacture. Packages vary
depending on the pump design and requirements.
Each lift-out chain package is designed to mount to
the top of the pump and allow the pump to be safely
hoisted up the guide rail.
Rail Support Brackets: The SRA lift-outs are
designed to use 2" standard pipe for guide rails. A top
rail support bracket is available to be mounted to the
hatch frame. Intermediate brackets are available for
deep basins. It is recommended that if the rail length is
over 21' that an intermediate bracket be installed. After
every additional 20' of rail, another intermediate bracket
should be used for proper rail support.
Basin Covers: Myers has several types of basin
covers available for use with either fiberglass or
concrete basins. Basin hatch type covers are available
in either steel or aluminum construction. The basin
cover frame is designed to allow for mounting of rail
support brackets.
Basin Bottom: All cement pipe basins must have a
smooth level troweled bottom for level mounting of
discharge casting.
Junction Boxes: If a junction box is used in a
hazardous location, it must be a hazardous location
approved type with hazardous location cord
connectors. Wires from the junction box must pass
through a hazardous location seal connector.
Level Sensing Controls: Intrinsically safe type float
controls are recommended for all applications and
required for hazardous location/non-sparking service.
An intrinsically safe control panel relay will limit the
current and voltage to the level controls. A Myers
control panel can be supplied with this type circuitry.
The float level controls maintain the basin sewage
water level by controlling pump turn-on and turn-off
levels.
1. The lower turn-off control should be set so that the
pump stops at approximately the top of the pump.
Consult the factory for any settings below this
point.
2. The upper turn-on control should be set above the
lower turn-off control. The exact height between
the two controls is determined by the number of
pump starts desired and the depth of basin. A
maximum of 10 starts per hour should not be
exceeded.
3. The override control is set at a specified height
above the upper turn-on control.
4. The alarm control is set about 6" – 12" above the
override control.
5. No control should be set above the inlet invert.
Valves: It is recommended that all check valves and
shut-off valves be mounted outside the sump in a valve
box. (See typical drawing detail, Fig. 1.) Shut-off
valves should be of the water works approved type with
resilient rubber disk seat.
CAUTION: After the pump is installed and sewage
has entered the basin there is danger. Sewage
water gives off methane and hydrogen sulfide
gases, which are poisonous. Never enter a wetwell
unless proper confined space entry procedures are
followed.
INSTALLING RAIL SYSTEM PARTS (Fig. 3)
Mounting Cover, Discharge Base and Rails
1. Set concrete cover with hatch opening in position.
2. Bolt top rail support plates (Fig. 6) to hatch frame.
The plate has slots so the two plates in a duplex
system can be adjusted to obtain required centerto-center distance between pumps.
3. Lower the base or base/elbow assembly into the
basin.
4. Position the base elbow assembly by dropping a
plumb line from center of pipe supports, located
on top rail support plate, to center of tapered
pins protruding from the top of the base elbow
assembly. Level the elbow flange in two directions,
3
23833A546 11/08/12
90° to each other. Shims may be required under
the base in order to obtain this level condition.
Mark the position of the base hold down bolts
through the holes in the base.
5. Move the base aside to allow drilling of the
concrete for 3/4" expansion bolts, 2-1/2" long.
Move the base over the bolt holes and recheck with
level and plumb line. Install expansion bolts.
6. Cut the pipe guide rails to the proper length and
install them between the pipe supports at the top
of the basin and pins on the base. Guide rails are
Schedule 40, galvanized or stainless steel.
7. Install discharge pipe as required by the particular
job specifications.
5. Re-check rails; they must be straight and plumb.
Move intermediate guide bracket if necessary to
perfectly align rails. After alignment is secured,
tighten nuts on U-bolt.
6. If a second intermediate guide bracket is used, the
above procedure is followed for installation.
Attaching Mounting Plate to Pump
1. Attach the mounting plate with the supplied bolts.
(See Parts List, page 5.) The mounting plate
should be turned so that the two locating pins are
horizontal when attached to the pump discharge.
2. Mount the guide plate to the mounting plate using
the two set screws provided.
IMPORTANT: DISCHARGE PIPE AND GUIDE
RAILS MUST BE PARALLEL IF INTERMEDIATE
GUIDE BRACKET IS USED.
Installing Pump and Mounting Plate
1. Attach the lifting chain to the pump. This is done
by installing two eye bolts, or by installing the lifting
bail (Fig. 4) provided with the lifting chain package.
8. If the top rail support plate cannot be attached to
the hatch cover frame, a special rail bracket (Fig.
7) can be furnished for mounting directly to a pipe
cemented in the basin wall. This bracket is set and
aligned with discharge base the same as described
for the rail guide plate attached to the frame.

2. A hook is located on the top rail support (Fig. 3) to
hold the upper end of the chain when not in use.
3. Position pump so the guide rails are located in the
slots of the guide plate. Slowly lower the pump
down the guide rails to the base. The locating pins
(horizontal pins on mounting plate) should come to
seat in the inclined surface of the arms.
1. Remove guide rails (Fig. 3), and cut a piece from
each one. These pipes must be exactly the same
length and of a length that will permit installing the
intermediate guide bracket in the desired location.
2. Place the cut pieces of pipe over the guide rail pins
located in the base.
3. Set the intermediate guide bracket in position
with tapered guides into pipes. Put U-bolt around
discharge pipe and tighten lightly.
4. Measure from joint on tapered plug on intermediate
guide bracket to joint of tapered plug on top rail
support and cut two rails to this length. Put rails in
place and tighten screws in top rail support. Holes
are slotted to adjust for any error in rail pipe length.
23833A546 11/08/12
WARNING! Do not exceed working load limit
of chains and other lifting devices. Do not use
chains or lifting devices where failure could
result in loss of life. Examine chains and lifting
devices for deformation or damage before and
after each lift.
CAUTION: No persons should be in the sump
basin when pump is lowered into position!
Air Venting: Air tends to trap in the pump volute when
water raises in the sump or when the pump is lowered
into water after service. To vent off this air, a small hole
is drilled into the pump volute. Be sure this vent hole
is clean after any service work on pump. Air venting
is not a problem after initial start.
