MODEL 73 SERIES SINGLE SEA VIEW STRAINERS

Application

Kraissl duplex strainers and filters provide a simple, cost effective way to separate particle impurities from fluid systems. Duplex strainers are ideal for applications where continuous flow must be maintained with no flow interruption for basket cleaning. Kraissl Model Series Sea-View are designed to protect cooling systems on marine engines and cooling water installations requiring pipeline strainers, direct sea water cooling, and indirect heat exchanger cooling. In both cases, cooling water strainers are very important. With direct cooling, marine debris can damage the cooling water pump causing the engine to fail, resulting in major repairs. Marine debris can also clog heat exchangers, requiring down-time until cleaned. Installation of cooling water strainers reduces these hazards, increasing the reliability of marine engines. Fine mesh filter baskets can also be provided for use with water supplies and other process flow-line installations.

Design

Kraissl Model 73 Sea-View Strainers offer the following advantages:

Transparent plastic sumps permit visibility of cooling water flow and collected material. Interior or exterior flow permit collection of particles in either the removable basket or in the transparent sump. Baskets are easily accessible without the use of tools. The basket is removed via the hand clamp closure and the removable sump by two wing nuts. Mounting brackets are provided on both simplex and duplex models. These units are very light weight while providing large straining area. Both simplex and duplex units are available in a range of sizes from 1/2 to 4-inch. When installed above the cooling water pump, the strainer becomes a quick means of pump priming. Interchangeable basket elements are available for a wide range of particle separations. Standard Kraissl Model 73 series strainers are manufactured of cast bronze, or stainless steel with transparent plastic basket sumps. Special valve plugs can also be furnished in stainless steel or other materials.Standard strainer baskets are of perforated monel or stainless steel. Duplex strainers are supplied with our special adjustable locking flange which permits adjustment of the tapered valve plug on its seat. A separate external gland is provided to allow easy access to valve stem packing without complete disassembly, even while in service, without changing the valve plug clearance.

The valve lever movement permanent stops and guard on the valve handle shields the side in use. The standard valve handle swings over the inlet port. Special reverse valve handles that swing over the outlet port can also be furnished. Internal channels are 100% full flow having the same cross-sectional area as the equivalent size pipe. Refer to our drawings B3523A and Al 732E for sizes and dimensions. Kraissl products are individually tested toour stringent quality control specifications. These cast pipeline strainers are manufactured according to international standard A.S.T.M. F1199 for use in industrial and marine applications.
