Installation, Operation & Maintenance Manual
MECHANICAL INSTALLATION:
PUMPS WITH AUTOCOUPLING
SYSTEMS
The HOMA Auto-Coupling is a quick removal
system used in keeping personnel from having
to enter the wet well. The pump mounts on a
stationary base and operates completely or
partially submerged (min. 8” above volute) in the
pumping media.
The HOMA Auto-Coupling kit includes a base
elbow, guide claw flange and upper guide rail
bracket. Kit also includes a profile seal and base
anchor bolts. Refer to dimensional drawing for
details.
CTP Series pumps with horizontal threaded
discharge, attach the guide claw flange to the
pump discharge flange as follows:
1. Inspect threaded assemblies for damage.
2. Clean threaded portions of pump discharge
flange and guide claw flange and locate set
screw location.
3. Install profile seal (if not already installed at
factory) into the guide claw with large
diameter fitted into groove inside of claw.
4. Apply pipe sealant to the threads of the
discharge.
When installing the pump onto a larger auto-
coupling an increaser bushing will be
included with the pump. Use a thread locking
compound such as blue #242. Apply thread
locking compound to the discharge threads.
Thread the bushing onto the discharge and
tighten.
5. Thread guide claw flange on to pump
discharge fully. DISCHARGE THREADS
ARE NOT NPT. DO NOT OVER TIGHTEN.
6. Tighten guide claw flange until the claw is in
upright (horizontal) position.
7. Apply thread locker to the set screw included
with the guide claw and tighten set screw.
For flanged discharge pumps, attach the
guide claw with the fasteners and gasket
provided. Flanges are raised face type,
improper tightening will damage the flanges.
Tighten the bolts in a crosswise fashion
evenly and in steps. Do not tighten one side
and then the other or the flanges will break.
Do not over tighten the bolts or the flanges
will break.
For all pumps, properly locate the base and
with anchor bolts provided fasten to the floor of
the pump station. Make sure when locating and
securing the anchor bolts that the base will align
properly with the access cover at the top
elevation of the station. (Refer to outline drawing
in appendix). Level the base before completely
tightening the anchor bolts. If base is not level,
proper sealing of the pump to base may not
occur!
Place the guide rail pipes (supplied by others),
cut to length into the rings of the base. The rails
will be secured at the top of the pump station
with the upper guide bar bracket and will extend
down to the sump floor.
For stations exceeding 15 feet in depth,
intermediate guide bar brackets are
recommended. One bracket is recommended
for each additional 15 feet of station depth.
Install upper guide bar bracket as shown on
outline drawing located in the appendix. Do not
tighten mounting bolts completely at this point.
Check that the guide system is properly installed
in the vertical orientation by using levels and a
plumb line. Then tighten upper guide anchor
bolts. Connect the station riser piping to the
outlet flange of the base.
INSTALLATION OF PUMPS WITH
RING STANDS:
The ring stand design allows for simple
economical installation and can be transported
from one installation to another. It is intended to
operate completely or partially submerged in the
pumping liquid.
For pump models without integral support feet,
install the ring stand to the underside of the
volute with the supplied fasteners. Apply a
thread locking compound to threads before
installing, such as blue #242 thread locking
compound.
