CAUTION
This 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. 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.
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 provid ed, use a contactor with a proper over load. 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:
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. 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.
2.5. Avoid unnecessary fittings. Select sizes to keep fric­tion losses to a minimum.
2.6. Units may be installed horizontally, inclined or vertically.
Always disconnect electrical power when handling pump or controls.
Liquid Temperature: 212ºF (100ºC) with standard seal
Never draw piping into place by forcing the pump suction and discharge connections.
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. 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 connections.
4. Discharge Piping
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.

and pump.
4.3. Use 3 to 4 wraps of Teflon tape to seal threaded connections.
5. Rotation
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.

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 operating conditions and temperature has stabilized. Check for expansion of piping.
7. Maintenance
7. Maintenance
7.1. Ball bearings are located in and are part of the motor.
They are permanently lubricated. No greasing required.
8. Disassembly
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).
coupled 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.
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 shaft with the seal housing.
8.4.6. Push out the mechanical seal stationary seat

9. Reassembly
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.
It is permissible to use a light lubricant, such as
9.4.2. Inspect casing O-ring (513) and replace if
