Multistage Centrifugal Pumps
Vertical Inline Models
Refer to pump manual 1808-634-00 for General Operating and Safety Instructions.
All units are for use with non-ammable, non-abrasive liquids compatible
with pump component materials.
IMPORTANT: Not for use with petroleum based liquids.
INSTALLATION
MOUNTING
Preferred mounting position is with motor shaft aligned vertically.
(See Figure 1)
1. Choose a solid, level surface with adequate support such as a concrete
slab oor.
2. Use a level against pump to check for plumb. For uneven surfaces, shim
beneath feet of Casing (Ref. No. 38) to attain proper alignment.
3. Securely fasten Casing to mount surface at all four mount holes to avoid
tip-over of pump. If space limitations dictate, pump may also be mounted
horizontally if adequate support is provided. Do NOT mount motor end
down or with shaft centerline below horizontal plane.
PIPING
Pump may have a protective cover over inlet and outlet for shipping purposes.
If present, be sure to remove these covers prior to attaching piping. If ange
Screws (Ref. No. 41) are loosened, be sure to re-tighten evenly and torque to
33 ft-lbs [45 N-m] to avoid Gasket (Ref. No. 39) failure.
Starving the pump of liquid could cause low performance and damage to pump
and seal. To avoid this, use suction piping that is short and either matches
pump port diameter or is larger, do not reduce. Also, immediately preceding
pump inlet, provide a section of straight pipe equal in length to a minimum 4
diameters of pipe size and avoid using valves.
These pumps develop very high pressures. Be sure to conrm that pressure
rating of all piping and ttings is adequately sized before use. Rating must be
su󰀩ciently larger than the combination of both inlet pressure plus the maximum
pressure pump can develop.
DESCRIPTION
APPLICATIONS
These commercial/industrial centrifugal pumps are non-self-priming (gravity feed) units designed to handle high-pressure/low-ow liquid transfer applications
where no suction lift is required. Typical installations include hot and chilled water, boiler feed, condensate return, irrigation, high pressure wash-down, booster
service, and sprinkler systems. These pumps have NOT been investigated for use in potable (drinking) water systems.
FEATURES
The in-line port design and compact footprint of these pumps allows for a clean installation. All models feature a shaft seal that can be replaced easily without the
need to disassemble the entire pump. An optional ANSI/ASME ange kit is available. Pumps are equipped with high e󰀩ciency closed impellers, and have a cas-
ing working pressure to 536 ft./232 psi [1600 kPa]. Handle liquid temperatures from 40° F to 180° F [4° to 82° C]. For use with clear, nonabrasive, nonammable
liquids compatible with pump component materials.
MOTOR
All models have 3450 RPM (2850 RPM for 50 Hz) continuous duty TEFC motors. Single phase units are capacitor start and have automatic reset thermal protec-
tion. All models are manual mode and require eld wiring, no controls are supplied.
Motors have multi-voltage options. To avoid damage to motor, be sure to arrange internal motor wiring to match electric supply voltage before applying power
(see motor nameplate for specic wiring diagram).
PUMP CONSTRUCTION
Pump construction is cast iron casing and adapter; 304 stainless steel impellers, chambers and column; Teon® wear rings; 304L stainless steel pump shaft
with tungsten carbide sleeve bearings; EPDM o-rings and gaskets; a mechanical shaft seal of stainless steel, carbon graphite, and tungsten carbide wear faces.

Piping and/or pipe ttings with an insucient pressure rating may burst
and cause personal injury and/or property damage.
MAXIMUM INLET PRESSURE
“1” Series
2 to 25 ...................................................................... 335 ft./145 psi [1000 kPa]
27 stage ................................................................... 500 ft./217 psi [1500 kPa]
“3” Series
2 to 15 ...................................................................... 335 ft./145 psi [1000 kPa]
17 to 25 .................................................................... 500 ft./217 psi [1500 kPa]
“5” Series
2 to 9 ........................................................................ 335 ft./145 psi [1000 kPa]
10 to 29 .................................................................... 500 ft./217 psi [1500 kPa]
If system pressure has potential to exceed number listed above, then a check
valve is required on discharge side of pump. This will ensure that proper inlet
pressure is maintained when pump shuts o󰀨.
MAXIMUM OUTLET PRESSURE
If system pressure in excess of 536 ft./232 psi [1600 kPa] is possible, then it is
necessary to provide means to prevent this. Examples include a bypass valve
or pressure switch on discharge of pump set at or below this number.
OPERATION
Become familiar with pump components (See Figure 2).
Vent Plug (Ref. No. 13) – Used to purge air from pump.
Wash Plug (Ref. No. 11) – Used in applications where seal wash is desired to
extend life of shaft seal.
Bypass Valve (Ref. No. 43) – Connects suction and discharge sides of pump,
making lling/draining procedure easier. During operation, bypass valve must
be closed.
Never run pump dry or with ow shuto. When pump is running, always
maintain a minimum ow of 4 gpm [0.9 m3/h] to avoid damage to pump.
STARTUP PROCEDURE
To avoid pump damage, it is very important to purge all air from pump
before initial startup.
1. Close discharge valve if present.
NOTE: Make sure bypass valve is closed.
2. Permit liquid to ow into pump thru suction port by gravity.
3. Allow air to escape from pump by cracking open Vent Plug (Ref. No. 13)
in top of pump housing near motor.
4. Wait for liquid to cease sputtering. When liquid ow changes to a steady
stream with no air, close Vent Plug.
5. Run pump briey, then repeat steps 1 thru 4 repeatedly until all air is
evacuated. Pump is now ready to be run.
ROTATION
Proper rotation is CLOCKWISE when looking up at shaft end of motor, see
directional arrow cast into motor Adapter (Ref. No. 8). Bump motor on/o󰀨 briey
to conrm motor is wired for correct rotation. Disregard rotation information
found elsewhere in safety manual.
DRAINING
1. Remove Bypass Valve (Ref. No. 43) and Vent Plug (Ref. No. 13)
completely.
2. Allow liquid to drain.
3. If pump is to be subjected to freezing temperatures, do not reinstall Valve/
Plug.
NOTE: When re-installing the Bypass Valve make sure the drain plug is
installed rst then install the valve. Failure to do so could result in performance
issues.
CYCLING
Frequent on/o󰀨 cycling can shorten motor life. System should be designed so
that pump is NOT starting more than 15 times per hour.
MAINTENANCE
Make certain that unit is disconnected from power source before
attempting to service or remove any components!
MOTOR REPLACEMENT
DISASSEMBLY
