Figure 5. Typical Automatic Air Release Valve Installation
The valve inlet must be installed between the pump
discharge port and the non-pressurized side of the
discharge check valve. The valve inlet is it at the
large end of the valve body, and is provided with
standard 1-inch NPT pipe threads.
The valve outlet is located at the opposite end of the
valve, and is also equipped with standard 1-inch NPT
pipe threads. The outlet should be connected to a
bleed line which slopes back to the wet well or sump.
The bleed line must be the same size as the inlet
piping, or larger. If piping is used for the bleed line,
avoid the use of elbows whenever possible.
NOTE
It is recommended that each Air Release Valve be
fitted with an independent bleeder line directed
back to the wet well. However, if multiple air
Release Valves are installed in a system, the
bleeder lines may be directed to a common
manifold pipe. Contact your Bombas Esco
distributor or the Bombas Esco company for
information about installation of an Automatic Air
Release Valve for your specific application.
ALIGNMENT
The alignment of the pump and its power source is
critical for trouble-free mechanical operation. In
either a flexible coupling or V-belt driven system, the
driver and pump must be mounted so that their
shafts are aligned with and parallel to each other. It
is imperative that alignment be checked after the
pump and piping are installed, and before operation.
NOTE
Check Rotation , Section C, before alignment of the
pump.
When mounted at the Bombas Esco factory, driver
and pump are aligned before shipment.
Misalignment will occur in transit and handling.
Pumps must be checking alignment, tighten the
foundation bolts. The pump casing feet and/or
pedestal feet, and the driver mounting bolts should
also be tightly secured.
