Design Features the idL Shaft Seal and Cenpeller Technology
The Eaton automatic self-cleaning strainer is a motorized unit designed for the continuous removal of entrained solids from liquids in pipeline systems, preventing damage to expensive pipeline system components. They have successfully performed in industrial, process, water & wastewater, power, paper and municipal applications for over 30 years.
All Eaton automatic self-cleaning strainers feature the unique idL™ shaft seal that positively prevents leakage from the backwash shaft at the top of the strainer. The special quad seal design replaces older, leak prone packing material. With Eaton's idL seal the exterior of the strainer stays dry and clean in service, there's never any bothersome external leakage or weeping of the process media down the sides of the strainer. Eaton automatic self-cleaning strainers with older style packing can be easily retro-fitted with the new idL seal. Kits are available for most strainers. You can download complete instructions and see a slide show illustrating a typical retro-fit installation in the Library. Click here to see the slide show.
A common problem in many 2" thru 8" automatic self-cleaning strainers is inefficient backwashing due to debris lodged in the strainer element. The Model 2596 Strainer features Eaton's Cenepeller™ Technology which solves this problem. A unique vane plate is positioned at the inlet of the strainer element where it contacts the flow before it enter the element. This vane causes the incoming flow to move in a circular motion, forcing the debris to lay up against the surface of the strainer element rather than impinging on the element and lodging in the element's openings. Lodged debris in the strainer element can negatively impact the differential pressure across the strainer, resulting in a shut down of the strainer while the element is manually cleaned. Cenpeller Technology in the Model 2596 Strainer helps prevent this problem while it makes backwashing easier and more efficient.

With an automatic control system monitoring the strainer operation, cleaning is accomplished by an integral backwash system. A small portion of the screen element is isolated and cleaned by reverse flow. The remaining screen area continues to strain – providing uninterrupted flow. With this efficient design, only a small amount of the liquid being strained is used to carry away the debris from the strainer.
The Model 2596 is available in sizes 2" through 24" in cast construction and 2" through 60" in fabricated construction. Design and construction are in general accordance with ANSI and ASME Sec. VIII, Div. 1. A wide range of screen designs and perforation / mesh sizes are available to meet the requirement of any straining application.

Applications Overview
Eaton's automatic self-cleaning strainers are commonly used on water service where the disposal of debris and backwash water is not a problem. Continuous flow is assured and protection is provided for nozzles, pumps, valves, heat exchangers and process equipment.
These units can also successfully handle other fluids such as white water, black liquor, starch, fuel and lubricating oil, caustic solutions and cooking oils. A determining factor in these cases is the recycling of the backwash fluid. Automatic self-cleaning strainers will significantly reduce maintenance costs and provide uninterrupted flow. They are a particularly worthwhile investment where the solids loading is high or upset conditions occur. Frequently, cleaning and servicing of manual strainers is costly, and if not properly attended, serious disruptions to the entire piping system can occur. Also, they are an ideal solution for maintenance problems where the strainer is in an inaccessible location.
Typical Applications
Automatic self-cleaning strainers are used in nearly every industry to strain fresh, brackish, or salt intake water for plant services; cooling, process, fire protection, etc.
- Process Industry – Protect heat exchangers, pumps, valves and water spray nozzles.
- Power Industry – Protect heat exchangers, pump seal water, traveling screen wash water.
- Pulp & Paper – Removing fibers from white water filtrate preventing clogging of nozzles. Separate bark and chips for recycling.
- Sewage/Waste and Water – Straining secondary effluent – thereby protecting spray nozzles while also providing clean plant service water.
- Primary Metal Industry – Provide clean water for quenching, descaling, blast furnace cooling.
