Thompson Strainer
Dependable, Low Maintenance Filtration
The Thompson Strainer is patented stainless steel strainer used
on a wide variety of industrial applications to remove solid particles from liquid
systems. Our unique product has grown popular due to its patented, low-maintenance design,
stainless steel construction, and exceptional efficiency.
All models of the Thompson Strainer operate with less than a 1-PSI pressure loss at
maximum flow when clean. This efficiency provides real energy savings when compared to
strainer products that rely on energy consuming devices like spinners and torpedoes to
give a comparable cleaning action. Call us today for a free energy savings estimation.
The Thompson Strainers internal flow patterns are
responsible for making our unique product so effective. As liquid flows up through the
internal riser pipe and deflects off the inner surface of the conical shaped screen, heavy
sediments are forced downward, away from the screen, into the large debris reservoir.
Unlike traditional basket strainers, y-strainers, or bag filters, the Thompson Strainer
can be flushed while online and in service. Settled debris is easily removed by purging
through the debris flush port

Inefficiencies
Choosing a strainer with sufficient surface area is critical in
any application. The Thompson Strainer has significantly more surface area than most
traditional basket and y-strainers. With units available with connection sizes from
2 to 10, accommodation flow rates up to 2,000 GPM (higher flow rates are
achieved by manifolding multiple strainers), Miller-Leaman has a strainer that will fit
your specific needs.
As liquid flows up through the internal riser pipe and deflects off the inner surface of
the conical screen, heavy sediment is forced downward away from the screen and into the
large debris reservoir. Settled debris is easily removed by purging through the debris
flush port.
The strainer vessel is purged while online and in operation. By opening a valve on the
flush port, all debris in the lower reservoir is purged from the vessel, as shown. Back
flushing or taking the unit off-line is not required to perform this flushing procedure.
