Make sure the flange bolt holes align with the mounting
holes on the underside of the volute. Secure the pump to
the mounting flange with the fasteners that are specified
in the accessory fastener selection table below.

Notes:
• For pumps larger than 8" please consult factory.
• Flange bolts must be tightened in cross pattern to
avoid damage to the raise face flanges.
• Standard flange bolts are 316SS
• Standard anchors are plated steel.
• Autocoupling systems include qty. 4 M12 anchors for
the upper bracket. Torque to 51 Nm / 38 ft lb.
• Anchor bolt holes should be drilled to the actual di-
ameter of the anchor (M12 anchor requires 12mm
diameter hole).
10.7.4. JACKETED PUMP OPTION
The cooling jacket has been supplied based upon the
specified operating conditions of this application. It is im-
portant this jacket is function properly, or the internal mo-
tor components could become damaged.
Several cooling configurations are available depending
upon customer preference and system requirements. You
must know what configuration of cooling system is to be
used with the pump prior to installation. In some cases,
field test results may indicate a change of cooling method
is required. Consult factory for necessary changes to the
pump.
Cooling Requirements
Standard Media Cooled – This construction does not
require any external piping and it is completely self-con-
tained. This design is suitable for the routine collection
system application. No pump modifications are required.

• Required Hardware – Automatic air bleed valve
mounted in upper vent port or a ¼" or 3/8" elbow
and small block valve for venting. A length of hose
routed to the sump should be attached to either air
bleed or the block valve outlet.
• Start Up Requirements – This jacket must be vent-
ed at start up. Additional venting may be required af-
ter situations where the suction or discharge piping
has been removed for maintenance and reinstalled.
Some adverse operating conditions can allow air to
become trapped in this jacket. This must be periodi-
cally vented off. If this occurs, it is recommended the
small air bleed valve is utilized.
Media Cooled with External Flush - This construction
requires an external flow of water, typically re-use water.
Applications which require this option are typically heavy
slurry or sludge service often found in the treatment plant.
This option routes the externally supplied water into the
pumped media. No pump modifications are required.
• Required Hardware – Mounting a regulating valve,
pressure gauge and automated block valve between
the water supply and the upper jacket port is re-
quired. The supply valve should be adjusted to allow
the supply of water to exceed pump discharge pres-
sure. This assures a positive flow of water into the
pump chamber. The block valve should be automated
to open whenever the pump is operated.
• Start Up Requirements – This jacket must be vented
at start up. Additional venting may be required if cool-
ing water supply is interrupted.
External Fluid Cooled - This option requires an external
flow of water like in option 2 above, but is used where
dilution of the pumped product is not desirable. The sup-
ply of water is internally isolated from the pumped media.
The water inlet is routed into the jacket's lowest port and
returned out of the highest port. This option does NOT
allow water to enter the pumped media and pump must
be ordered from factory this way.
• Required Hardware – Mounting a regulating valve,
pressure gauge and automated block valve between
the water supply and the upper jacket port is re-
quired. The supply valve should be adjusted to allow
for a good supply of water to flow through the jacket.
The block valve should be automated to open when-
ever the pump is operated.
• Start Up Requirements – This jacket must be vented
at start up. Additional venting should not be required.
Vent Valve Installation
HOMA dry pit pumps are supplied with a valve and fitting
that must be installed and maintained to ensure the prop-
er performance of these pumps.
The opening for this valve is located on the base of
the motor cap near the mounting screws. The pump is
shipped with a plug installed which must be removed pri-
or to start up.
This opening is a metric straight thread and requires an
adapter included with the valve and fitting hardware. It is
also recommended that a length of hose be attached to
the valve and routed back to the sump.
