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 (minimum 8” over volute) in
the pumping media.
The HOMA Auto-Coupling kit consists of a base
elbow, guide claw flange, and upper guide rail
bracket. The kit also includes a profile seal and
base anchor bolts.
TP 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
suitably sized anchor bolts, fasten it 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. 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 to extend down to the
sump floor.
For stations exceeding 10 feet in depth
intermediate guide bar brackets are recommended.
One bracket is recommended for each additional
10 feet of station depth.
Install the upper guide bar bracket to maintain
vertical orientation of the guide rails. 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.
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.
