Ideal for accommodating space and access constraints, vertical tank
mounted assemblies available in both simplex and duplex versions are one of many options available to meet you needs.
Unitary Base
Large Capacity priming systems can
be located where space is limited. The above drawing of a duplex vacuum priming system
has a mere 72" x 55" foot
print, includes 10 HP liquid ring vacuum pumps, a 240 gallon vertical
vacuum receiver, and is furnished fully assembled onto a common base. This system will establish a prime to 2,000 Ft3
of
suction piping requiring a 20 foot lift, in under 10 minutes, and will
easily maintain a prime to a bank of centrifugal pumps providing for
immediate start-up when needed.
Stacked Design
Our Stacked Design minimizes overall system footprint of this
20 HP Duplex Vacuum Priming System with 630 gallon vacuum receiver shown
on the right. This option with its modular design minimizes handling
difficulties associated with large unitary base systems, especially if
equipment is to be located within an existing building.
System sizes through our APD-200RV-240V in stacked design
are also able to fit through 36" doorways so that they can be readily located in hard to
access areas.
Large Capacity
Even large capacity systems, (25 HP and above) can be
provided nearly fully assembled for minimum field assembly requirements.
System shown is a 60 HP Duplex system designed for a siphon assist
application with 72"Ø lines. Systems can
designed for installation in unprotected areas, however, recommended
installation is to always provide at least overhead protection from the
elements. This particular installation included a field assembled
enclosure for the pump skid.
When designing large capacity systems it is necessary
to consider how the priming system will be isolated from the water side
of the process. Typical priming valves cannot handle the flow capacity
requirements of large applications. Several design options are available
such as the pneumatically isolated, level controlled chamber shown here.
Designs such as this provide controlled isolation between the water and
vacuum sides of the process without restricting the flow. Local controls
are provided for operation independent of the vacuum priming system.
