GRP Series
Installation, Operation & Maintenance Manual
MECHANICAL INSTALLATION:
PUMPS WITH AUTOCOUPLING SYSTEMS
The HOMA Auto-Coupling is a quick removal
system used to prevent personnel from needing to
enter the wet well.
The HOMA Auto-Coupling kit includes a base
elbow, guide claw flange and upper guide rail
bracket. The kit also includes a profile seal and
base anchor bolts. Refer to “Auto-Coupling Parts
ID” technical page on website.
For GRP 10 - 50 Series pumps with horizontal 2”
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.
5. Thread guide claw flange onto 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 GRP 12 and 19 Series pumps with vertical,
1¼” threaded discharge (note: this assembly can
be ordered with or without integral check valve),
attach the pump discharge flange as follows:
1. Inspect threaded assemblies for damage.
2. Clean threaded portions of pump discharge
flange, nipple and riser pipe.
3. Apply pipe sealant to the male threads.
4. Thread guide claw riser pipe (either style) onto
the pump discharge with the provided 11/4”
close nipple. Tighten the assembly until the
opening in riser pipe points away from pump and
is parallel with the cable entry.
5. Bolt the guide claw flange with rubber gasket to
the riser pipe using the SS nuts and bolts provided.
6. Install profile seal (if not already installed at
factory) into the guide claw with large diameter
fitted into groove inside of claw.
7. For check valve version install second gasket,
drop in check ball, and fasten the cover with nuts
and bolts provided.
Important: Do not install more then one (1)
check valve into any pump discharge piping
system or problems will occur.
For GRP 59 to 118 Series pumps , attach the
guide claw flange to the pump discharge flange
with the fasteners and gasket included with the
auto-coupling kit. Tighten the bolts to the proper
torque. Install profile seal (if not already installed at
factory) into the guide claw with large diameter
fitted into groove inside of claw.
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 will extend down to
the sump floor.
For stations exceeding 10 feet in depth, inter-
mediate 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.
