WARNING

Hazardous fluids can cause fire, burns or death.

CAUTION

TO AVOID SERIOUS OR FATAL PERSONAL INJURY OR MAJOR PROPERTY DAMAGE, READ AND FOLLOW ALL SAFETY INSTRUCTIONS IN MANUAL AND ON PUMP.

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.

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 Temperature: 212ºF (100ºC) with standard

seal 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 MCC is a close coupled, end suction, centrifugal pump for general liquid transfer service, booster applications, etc. Liquid-end construction is cast iron and AISI Type 316 stainless steel. Impellers are fully enclosed, non-trimmable to intermediate diameters.

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.

1.3. Motors must be wired for proper voltage. Motor wir-

ing diagram is on motor nameplate. Wire size must

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

CAUTION

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.

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

5.1.2. Three-phase motor: Interchange any two

power supply leads.

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.

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 con-

nections.

6. OPERATION

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.

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.

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).

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.

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.

9.5. Check reassembled unit for binding. Correct as

required.

9.6. Tighten casing bolts in a star pattern to prevent O-

ring binding.
