Patented detour pattern ensures leak-proof insulation of the basket during cleaning.

No more rushing to get the job done before the out-of-use room overflows. And…without overflow, there is no cleanup.

Trouble-free maintenance of strainer baskets

Our duplex strainers remove dirt and debris from pipelines and protect sensitive system components. The model 53BTX, has
a design that makes maintenance of the strainer basket a breeze.
No more ˝race against the clock˝ during basket maintenance to prevent the filter chamber from overflowing with fluid. The model
53BTX keeps the room dry during maintenance. This gives you time to clean or replace the strainer basket without ever having to worry about leakage and overflow.

And…with no overflow, there is no need to clean up after maintenance on the strainer basket. The Model 53BTX is simply a better way to go.

A better double-sided screen design

A unique flow distribution valve pattern in the Model 53BTX isolates the two screen basket chambers and prevents fluid bypass. An easy-to-turn handle operates the cartridge and redirects system flow from one chamber to another – the flow in the pipeline is never shut off.
When a strainer basket needs cleaning, the lever is turned to put it out of action and redirect the flow through the other chamber. The position of the lever clearly indicates which room is in use at all times.
No special tools are required to clean the strainer basket.
The chamber is first drained and then the lid is lifted from the opening of the chamber. The dynamic seals of the changing cartridge prevent liquid from entering the out-of-service chamber, ensuring trouble-free maintenance of the strainer basket.

A better flow detour pattern

The heart of the Model 53BTX is the unique flow detour pattern that features a patented, highly dynamic sealing system on the diverter balls. This ensures exceptionally long seat life and positive sealing.

This design works so well that there is no need for manual internal or external adjustment of the ball support. The low operating torque means that the screen can be operated with an easy-to-turn lever. A gearbox is not necessary.
A double sealing system on both the upper and lower handle protects against possible leakage. Special reinforced polymer seats are used for longer life.
Should a cartridge need to be replaced, this is easily accomplished. Just remove four bolts and the cartridge comes out through the top of the strainer. There is no need to completely disassemble the strainer or remove it from the pipe.

Better for all applications

The compact, low profile Model 53BTX fits into spaces where ordinary basket filters might not fit, but it still uses full-size strainer baskets for low differential pressure performance.
And, there is a strainer basket for every application. The standard basket is made of Type 316 stainless steel; but if needed, it is also available in Monel, brass or Hastelloy C materials. Cores with openings from 3/4˝ to 45 microns are offered: choose the best size for
for your application – without compromise.
For easy basket maintenance, there are two drain plugs, not just one, on each strainer basket chamber. In addition, there is an easily accessible vent valve on top of the filter housing.
Finally, the standard mounting feet ensure a rock-solid installation no matter where the filter is installed.
Available options for the Model 53BTX are differential pressure gauges, with or without switches, and magnetic separators installed
in the sieve basket for removing fine ferrous particles from the process media.

If the diverter valve needs maintenance, it slides out of the top of the filter housing.
A minimum of parts, easily replaced, makes maintenance tremendously time-saving.
