Model 52 Eaton Strainers

The Eaton Model 52 duplex basket strainer is a high performance industrial filtration solution engineered for heavy duty applications that require massive throughput and continuous flow. Designed to handle high flow rates with minimal pressure drop, the Model 52 is the ideal choice for larger pipelines from 10" to 18" in size where shut downs for maintenance are not an option.

The Model 52 does not use diverter plugs like smaller duplex strainers but a sophisticated butterfly valve design. These high quality valves work in unison and let operators switch flow from a dirty basket chamber to a clean one with minimal effort, even under high fluid pressures. This design provides a straight through flow pattern for very low pressure loss, often a requirement in large scale plumbing systems. To showcase this, a 10 inch unit can handle up to 2,000 GPM with a pressure drop of only 2 PSI.

This Eaton duplex basket strainer features a unique convoluted basket design with a pleated screen. This significantly increases the straining area while keeping the basket size compact. The larger surface area reduces pressure drop and extends the time between cleaning cycles, directly resulting in lower operating costs. The side entry flow pattern design of these strainers further improves performance through turbulence reduction.

Features & Options

• Construction: Cast Iron body (Bronze available on request).
• Butterfly Valve Operation: Synchronized valves provide easy, low torque switching without flow interruption.
• Convoluted Baskets: Pleated design maximizes straining area for longer service intervals.
• Continuous Flow: Perfect for systems that cannot be shut down for cleaning.
• Low Pressure Drop: Straight through flow design minimizes energy loss.
• Quick Open Covers: Provides fast, tool free access to baskets for maintenance.
• Connection & Sizes: Available in large diameters from 10" to 18" with flange connections.
• Pressure Rating: Rated for 200 PSI (10"–12") and 150 PSI (14"–18") at 100°F.

The Eaton Model 52 is widely used in demanding sectors such as chemical processing, water and wastewater treatment, marine operations, and general manufacturing. From filtering cooling water, process fluids, to chemical batches, this strainer provides reliable protection for pumps, heat exchangers, nozzles, and other pipeline equipment.

Model 52 Eaton® strainers are heavy duty duplex strainers with extra large basket chambers, filtration screens and specialized engineering to handle high flow rates. Model 52 Eaton® strainers are professional quality double basket strainers manufactured for high throughput, continuous flow applications. The Model 52 is ideal for work use where low pressure drop is important and high fluid flow rate is experienced. As a duplex strainer, Eaton’s® Model 52 is intended for use in filtration scenarios that cannot be shut down for system line maintenance. The Model 52 is designed with a set of easy operation butterfly valves that reduce the effort required to switch flow between strainer baskets when necessary for cleaning. Similar to Eaton's® other models, Model 52 strainers feature quick open covers for filter screen access, and no tools are required to switch strainer flow or to open strainer chambers.

Model 52 Eaton® strainers come in cast iron body material only with bronze casing available on request. The Model 52 comes as a flanged unit in size options 10", 12", 14", 16" and 18" in working plumbing diameter. The working pressure of the unit is 200 PSI (13.8 BAR) at 100°F (38°C) for 10" and 12" strainers and 150 PSI (10.3 BAR) at 100°F (38°C) for 14", 16" and 18" strainers. Gasket O-ring seals are Buna-N type standard. Strainer filter baskets come standard in stainless steel with choice of either perforated or mesh style screens. Perforated screen sizes range from 1/32" up to 1/2" and mesh screens are available in 20 mesh, 40 mesh and 60 mesh sizes.

When selecting basket screen style or sizes, a general rule of thumb is to select a strainer size slightly smaller than the smallest particle anticipated within the system to capture. Increasing size values of perforation style baskets indicates a greater flow area that is better suited to catching larger particles. Increasing values on mesh style baskets indicates more wire per inch and therefore a smaller pore width that is better suited for catching smaller, more fine particles.
