Stamped Stainless Steel
Centrifugal Pumps
Refer to pump manual 1808-634-00 for General Operating and Safety Instructions
DESCRIPTION
These centrifugal pumps are non-self priming (gravity feed) units designed for continuous duty liquid transfer and re-circulation. Pumps are intended for
use with clear, non-abrasive, non-flammable liquid
s compatible with pump component materials. Handle liquids from 40̊ to 200̊ F (4̊ to 93̊ C) with
standard Viton seals; 40̊ to 180̊ F (4̊ to 82̊ C) with optional Buna-N seals. Wetted parts include: Stainless Steel impeller and impeller nut; Stainless Steel
casing and casing cover; Type 21 mechanical shaft seal comprised o
f carbon, ceramic and stainless steel components; and Viton seals (Buna-N seals
Optional). High head units also include wetted Stainless Steel motor shaft. The discharge port on all models can be rotated 360̊ in 90̊ increments to
accommodate specific applications.
PUMPS
Motorized units are direct coupled to a 3450 RPM motor (see “Specifications” for additional motor data). Single phase pump motors have automatic
reset thermal protection. All models are manual mode and require field wiring, no controls are supplied. Check motor wiring before putting unit into
operation (see motors nameplate for specific wiring diagram).
PUMP HEAD
Some models are not equipped with motors. They are suitable for mounting to 3450 RPM, NEMA 56J face threaded shaft motors, with counterclockwise
rotation (looking at motor shaft). To find motor’s available horsepower multiply motor’s rated horsepower by service factor. This number must be equal to
or greater than that required by pump.
ASSEMBLY
MOTOR (FOR UNITS SHIPPED WITHOUT DRIVER
ONLY) (Refer to Figure 1)
If any parts are missing or damaged, do not attempt to assemble or
operate pump until repair parts are obtained and properly installed.
1.
Verify that motor conforms to ALL standards specified in
“Description”, and is equipped with slinger washer (Ref. No.
2) not included with pump.
2.
Place motor in vertical position with shaft end up. Set
adapter (Ref. No. 2) on top of motor.
NOTE:
Be sure to align adapter in desired position now. Rotating
adapter allows pump discharge port to be positioned at various angles.
3.
(For high
head
models only) Use fasteners and washers
(Ref. Nos. 3 & 4) to attached adapter to motor.
4.
See “INSTALLATION OF NEW SEAL” under “Maintenance”
section and follow steps to complete assembly of pump.
MAINTENANCE
Make certain that unit is disconnected from power source before
attempting to service or remove any components!
SHAFT SEAL REPLACEMENT
(Refer to Figure 1)
REMOVAL OF OLD SHAFT SEAL
1.
Disconnect power supply and piping.
2.
Place unit in vertical position with pump end up.
3.
Disassemble pump by removing fasteners and washers
(Ref. Nos. 12 & 13) which holds casing (Ref. No. 11) in
place. Lift off casing and casing seal (Ref. No. 10).
4.
Unscrew impeller nut (Ref. No. 9), and impeller (Ref. No. 7)
separately by turning each counterclockwise. Impeller seal
(Ref. No. 8) will also be freed at this time. If seal head (Ref.
No. 6 with spring) is retained on impeller, separate at this
time.
NOTE:
It may be necessary to use a soft hammer to tap outside of
impeller in a counterclockwise direction to loosen it.
NOTE:
Access to motor shaft is provided at end opposite pump (plug
may need to be pried out or cover removed). Use screwdriver in slot or
wrench on flats to keep motor shaft from turning.
5.
Lift off casing cover (Ref. No. 5) while pulling seal along with
it. Seal seat (without spring) can now be freed by pressing
through from rear of casing cover.
IMPORTANT: Do not damage motor shaft, impeller stem or seal cavity
in casing cover as this may cause leaks.
