Automatic Strainer and Filtration Systems
Automatic strainers and filters reduce labor costs and product loss associated with manually cleaned
pipeline strainers and bag filter systems. Our website
illustrates several different styles of automatic strainers and
filter systems; use the navigation tabs above or visit our
for descriptive links of each
webpage. Following is a summary of the different type of
automatic strainers and automatic filters that we offer, linked to
more detailed catalog pages.
This is a type of modified simplex strainer, having the drain port
connected to the bottom of the strainer basket, enabling "flushing"
of retained particles when the drain valve is opened. The
effectiveness of the cleaning is dependent upon the differential
pressure of the system compared to the (presumably)
atmospheric pressure of the drain port. Other factors include
the particle characteristics, if they tend to be hard and
non-deformable, this strainer design provide a low-cost/tech
approach for reducing labor related expenses.
Flushing Strainer Catalog Page
automatic backwashing strainer uses some of the fluid already
strained to dislodge particulate embedded within the filter element.
This is accomplished by effectively reversing the flow through
the element and out the drain port using an internal nozzle
assembly which slowly rotates within the element.
Approximately 5% of the flow is used for backwashing the filter
element and the duration of the cleaning cycle is typically 3-5

MECHANICALLY CLEANED STRAINERS
type of strainer is used for non-water fluids or for applications
where it is important to minimize product loss. Very often
these are used for viscous fluids and other difficult to filter
fluids such as paint, wax, and food/beverage applications. An
internal disc wipes the surface of the element, pushing all of the
retained particles to the purge chamber. When the drain valve
is opened, the system pressure flushes the particles out the drain.
The cleaning cycle is typically <1 second and the volume of
solids/fluid <1 gallon. The internal stroke frequency and the
purging frequency are set with programmable timers.

TUBULAR BACKWASHING FILTER SYSTEMS
systems are generally used for particle retentions as fine as 100
mesh (150 microns), with some exceptions. Filter systems are
designed to retain particles as small as 1 micron. Tubular
backwashing filter systems temporarily reverse the flow through the
filter element, backwashing and dislodging embedded particulate.
When continuous flow is required, the filter system will consist of
multiple chambers, ensuring that a minimum flow and a constant
discharge pressure is maintained during the cleaning cycle.

For high capacity and high viscosity
applications we can install several strainer or filter housings in
series, having a common inlet, outlet and drain manifold. This approach helps ensure a consistent
pressure and can be designed to support future expansion.
