General Description:

While the model 850's standard dimensions are based on standard commercial fittings, the unit can be designed to accommodate almost any piping restriction. It is available with butt weld or flanged connections. It is economical and readily available in almost any weldable material. The convoluted basket, which is standard on the model 850, gives the design an advantage of 170% in screen area over competitive equivalents. In larger sizes, the model 850 can be economical and functionally better than the "Y" Strainer. model 850 Tee Type strainers are most frequently used for pump protection applications.

Special Features:

The Fabricated model 850 is a composite of special features which can be tailored to accommodate the toughest applications.
Maintenance: The model 850 is available with quick opening closure for easy operator access. The convoluted basket has a single rail reinforcing bar which allows it to slide in and out easily and can be installed in any orientation compared to "Y" strainers.

The model 850 can be specifically designed to meet very tight dimensional restrictions. It can also be designed for straight-through or right-angle flow, making it ideal for retrofit situations in which strainers were initially omitted.

Pressure Drop:

Perhaps the most important feature of the model 850 is its low pressure drop. The combination of convoluted screen and unrestricted floe path, provides resulting pressure losses equal, in some cases, to 1/2 that of an equivalent basket strainer. While the model 850 has a screen equal in size to 1/2 the equivalent basket strainer, its pressure drop makes it ideal for applications such as condensate and boiler feed pump suction where water quality is good and pressure drop is very critical.

Design Data:

The model 850 is treated as a pressure vessel rather than a fitting. As such, it can be designed to practically any operating conditions per code. It can be lined, making it ideal for certain applications (scrubbers, etc.)
