THIS MANUAL IS INTENDED TO ASSIST IN THE
INSTALLATION AND OPERATION OF THIS UNIT
AND MUST BE KEPT WITH THE PUMP.
This is a SAFETY ALERT SYMBOL.
When you see this symbol on the pump
or in the manual, look for one of the
following signal words and be alert
to the potential for personal injury or
property damage.
Warns of hazards that WILL cause
serious personal injury, death or major
property damage.
Warns of hazards that CAN cause
serious personal injury, death or major
property damage.
Warns of hazards that CAN cause personal injury or property damage.
NOTICE: INDICATES SPECIAL INSTRUCTIONS
WHICH ARE VERY IMPORTANT AND
MUST BE FOLLOWED.
THOROUGHLY REVIEW ALL INSTRUCTIONS
AND WARNINGS PRIOR TO PERFORMING ANY
WORK ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.
UNIT NOT DESIGNED FOR USE
WITH HAZARDOUS LIQUIDS OR
FLAMMABLE GASES. THESE
FLUIDS MAY BE PRESENT IN
CONTAINMENT AREAS.
1.3. Motors must be wired for proper voltage. Motor
wiring diagram is on motor nameplate. Wire size
must limit maximum voltage drop to 10% of nameplate voltage at motor terminals, or motor life and
pump performance will be lowered.
1.4. Always use horsepower-rated switches, contactor
and starters.
1.5. Motor Protection
1.5.1. Single-phase: Thermal protection for single-
phase units is sometimes built in (check nameplate). If no built-in protection is provided,
use a contactor with a proper overload.
Fusing is permissible.
1.5.2. Three-phase: Provide three-leg protection
with properly sized magnetic starter and
thermal overloads.
1.6. Maximum Operating Limits:
Liquid 212ºF (100ºC) with standard seal
Temperature: 250ºF (120ºC) with high
temperature seal.
Working Pressure: 75 PSI with standard seal
125 PSI with optional seals.
Starts per Hour: 20, evenly distributed.
1.7. Regular inspection and maintenance will increase
service life. Base schedule on operating time. Refer
to Section 8.
2. INSTALLATION
2.1. Locate pump as near liquid source as possible (below
level of liquid for automatic operation).
2.2. Protect from freezing or flooding.
2.3. Allow adequate space for servicing and ventilation.
2.4. All piping must be supported independently of the
pump, and must “line-up” naturally.
DESCRIPTION and SPECIFICATIONS:
The Model MCS is a close coupled, end suction, centrifugal pump for general liquid transfer service, booster
applications, etc. Liquid-end construction is all AISI Type
304 stainless steel, stamped and welded. Impellers are
fully enclosed, non-trimmable to intermediate diameters.
Casings are fitted with diffusers for efficiency and for
negligible radial shaft loading.
All units have NEMA 48Y or 56Y motors with square
flange mounting and threaded shaft extension.
1. IMPORTANT
1.1. Inspect unit for damage. Report any damage to car-
rier/dealer immediately.
1.2. Electrical supply must be a separate branch circuit
with fuses or circuit breakers, wire sizes, etc., in
compliance with National and Local electrical codes.
Install an all-leg disconnect switch near pump.
Always disconnect electrical power when
handling pump or controls.
Never draw piping into place by forcing
the pump suction and discharge connec-
tions.
2.5. Avoid unnecessary fittings. Select sizes to keep fric-
tion losses to a minimum.
2.6. Units may be installed horizontally, inclined or verti-
cally.
Do not install with motor below pump.
Any leakage or condensation will affect
the motor.
2.7. Foundation must be flat and substantial to eliminate
strain when tightening bolts. Use rubber mounts to
minimize noise and vibration.
2.8. Tighten motor hold-down bolts before connecting
piping to pump.
3. SUCTION PIPING
3.1. Low static suction lift and short, direct, suction pip-
ing is desired. Consult pump performance curve for
Net Positive Suction Head Required.
3.2. Suction pipe must be at least as large as the suction
connection of the pump. Smaller size will degrade
performance.

3.3. If larger pipe is required, an eccentric pipe reducer

(with straight side up) must be installed at the pump.
3.4. Installation with pump below source of supply:
3.4.1. Install full flow isolation valve in piping for
inspection and maintenance.
Do not use suction isolation valve to
throttle pump.
3.5. Installation with pump above source of supply:
3.5.1. Avoid air pockets. No part of piping should be
higher than pump suction connection. Slope
piping upward from liquid source.
3.5.2. All joints must be airtight.
3.5.3. Foot valve to be used only if necessary for
priming, or to hold prime on intermittent
service.
3.5.4. Suction strainer open area must be at least
triple the pipe area.
3.6. Size of inlet from liquid source, and minimum
submergence over inlet, must be sufficient to prevent
air entering pump through vortexing. See Figures 1
through 4.
3.7. Use 3 to 4 wraps of Teflon tape to seal threaded con-
nections.
5.1.2. Three-phase motor: Interchange any two
power supply leads.
6. OPERATION
6.1. Before starting, pump must be primed (free of air
and suction pipe full of liquid) and discharge valve
partially open.
6.2. Make complete check after unit is run under operat-
ing conditions and temperature has stabilized. Check
for expansion of piping.
7. MAINTENANCE
7.1. Ball bearings are located in and are part of the mo-
tor. They are permanently lubricated. No greasing
required.
Pumped liquid provides lubrication. If
pump is run dry, rotating parts will seize
and mechanical seal will be damaged. Do not operate
at or near zero flow. Energy imparted to the liquid is
converted into heat. Liquid may flash to vapor. Rotating
parts require liquid to prevent scoring or seizing.
8. DISASSEMBLY
Complete disassembly of the unit will be described. Proceed only as far as required to perform the maintenance
work required.
8.1. Turn off power.
8.2. Drain system and flush if necessary.
8.3. Remove motor hold-down bolts.
8.4. Disassembly of Liquid End
8.4.1. Remove casing bolts (370).
8.4.2. Remove back pull-out assembly from casing
(100).
8.4.3. Remove impeller locknut (304).
4. DISCHARGE PIPING
4.1. Arrangement must include a check valve located
between a gate valve and the pump. The gate valve
is for regulation of capacity, or for inspection of the
pump or check valve.
4.2. If an increaser is required, place between check valve
and pump.
4.3. Use 3 to 4 wraps of Teflon tape to seal threaded
connections.
5. ROTATION
5.1. Correct rotation is right-hand (clockwise when
viewed from the motor end). Switch power on and
off quickly. Observe shaft rotation. To change rotation:
5.1.1. Single-phase motor: Non-reversible
4
Do not insert screwdriver between impel-
ler vanes to prevent rotation of closecoupled units. Remove cap at opposite end of motor. A
screwdriver slot or a pair of flats will be exposed. Using
them will prevent impeller damage.
8.4.4. Remove impeller (101) by turning counter-
clockwise when looking at the front of the
pump. Protect hand with rag or glove.
Failure to remove the impeller in a
counter-clockwise direction may damage
threading on the impeller, shaft or both.
8.4.5. With two pry bars 180 degrees apart and
inserted between the seal housing (184) and
the motor adapter (108), carefully separate
the two parts. The mechanical seal rotary unit
(383) should come off the shaft with the seal
housing.
8.4.6. Push out the mechanical seal stationary seat
from the motor side of the seal housing.
9. REASSEMBLY
9.1. All parts should be cleaned before assembly.
9.2. Refer to parts list to identify required replacement
items. Specify pump index or catalog number when
ordering parts.
9.3. Reassembly is the reverse of disassembly.
CAUTION
9.4. Observe the following when reassembling the liquid-
end:
9.4.1. All mechanical seal components must be in
good condition or leakage may result. Replacement of complete seal assembly, whenever seal has been removed, is good standard
practice.
It is permissible to use a light lubricant, such
as glycerin, to facilitate assembly. Do not
contaminate the mechanical seal faces with
lubricant.
9.4.2. Inspect casing O-ring (513) and replace if
damaged. This O-ring may be lubricated with
petroleum jelly to ease assembly.
9.4.3. Inspect guidevane seal ring (349) and replace
if worn.
Do not lubricate guidevane seal ring
(349). Insure it is not pinched by the
impeller on reassembly.
9.5. Check reassembled unit for binding. Correct as
required.
9.6. Tighten casing bolts in a star pattern to prevent
O-ring binding.
