Model KR Self-Cleaning Strainer

Tate Andale Model KR Self-Cleaning Strainer
Where reliability and durability are a necessity and not an option – The “KR” is the answer.

Description The Model KR self-cleaning strainer is a cast iron continuous backflushing self-cleaning strainer. Featuring a rotating stainless steel backwash arm that is driven by an electric motor, the strainer is designed for installations, which will be unattended for extended periods of time. Utilizing a stainless steel wedgewire straining element, the Model KR self-cleaning strainer has the highest straining ratio available for normally sized strainers. When configured for automatic intermittent backflushing – which also reduces backwash effluent – the Model KR self-cleaning strainer allows longer periods between backflushing, minimizing operating costs. The wedgewire element also features a reverse wound design that prevents lodging of debris in the element, and creates a vortex during backflush for more efficient backflush operation. The Model KR self-cleaning strainer is the rugged, long-life, efficient, self-cleaning strainer of choice.

Heavy duty cast iron construction, ideal for water service.
Reverse wound Wellscreen straining element prevents debris from wedging in the “V” groove of the wedgewire. Also when the unit is backflushing, the flow goes from the wide opening to the narrow opening, which increases the velocity and produces a more efficient backflush.

The Model KR has a higher straining ratio than any other self-cleaning strainer, resulting in longer periods of time between backflushing. This high straining ratio minimizes electric and water utility costs and reduces required maintenance.

Optional Features

	Automatic intermittent backflushing control to conserve backflushing fluid
	Suction service units available
	Air, electric, or hydraulic operated flushing valves
	Sequential controls for multiple units
	Higher design pressures available
