13 HOW TO SELET HELLN STRINER There are six application requirements that should be addressed when selecting a specific Hellan Strainer model. Here are the considerations and options available for each requirement: 1 PERFORTION SIZE OF THE SREENS Hellan recommends that a screen perforation hole diameter be selected that is 40% to 60% of the diameter of the smallest orifice in the system. Selecting a smaller perforation than required leads to unnecessary cleaning cycles and higher pressure drops during operation. 2 SIZE OF THE STRINER ) Existing Pipe Size Method This method is used when a Hellan Strainer is installed in an existing network of piping. Flow rate and the attendant pressure drop are within the application requirements. In these situations, it is common practice to select a strainer size that matches the existing pipe size, i.e., an " strainer would be selected for an installation with an existing " line. ) Flow rate requirement versus pressure drop method This method should be utilized when selecting a strainer for a new application, or as a replacement strainer in existing systems where a specific flow rate needs to be maintained. Refer to the chart at right for flow rates of available strainer sizes. Refer to the pressure drop versus flow rate charts for various size strainers, appearing on pages 54 through 1. 3 STRINER ONSTRUTION MTERILS Hellan Strainers are available with cast bodies constructed in iron, steel, stainless, and bronze or fabricated in steel and stainless steel. Other materials are available by special order. The material used for internal components depends on the material of the body. (See pages 14 and 15 for standard materials of construction for strainers of various body materials.) The selection of a body material depends on three criteria: ) The operating pressure of the system The body material selected should have a pressure rating that is appropriate for the operating pressure of the system. (See page 15 for maximum pressure ratings for strainers of various materials and flange types.) ) The fluid to be strained Standard cast iron models are commonly used for fresh water applications, while other materials are used to meet special needs: cast stainless steel for highly corrosive fluids, and bronze or monel for seawater applications. ) The environment in which the strainer operates longer service life may be attained by specifying a construction material that is appropriate for the service environment. Stainless steel should be considered for highly corrosive environments and bronze for marine or other applications where salt air is present. 11 SREEN OPTIONS Perforated Screens Wedge-Wire Screens Round Opening Size Slot Width Fractional ecimal Metric Mesh Micron Inches Metric Mesh Micron 1/4" 0" 6.35 mm " 0.3 mm /16".1" 4.77 mm " 0.23 mm /".125" 3.1 mm " 0.1 mm /32".094" 2.3 mm " 0.13 mm /16".063" 1.59 mm " 0.10 mm /32".031" 0.79 mm Other perforated screen opening sizes and Wedge-Wire screen slot widths are available upon request.

20 UTOMTI STRINERS utomatic Hellan Strainers are used whenever automatic self-cleaning of the strainer is required or advantageous. Under normal operating conditions, these units can perform a complete cleaning cycle in just 15 seconds. This means that only a small amount of fluid is needed to flush solids from the strainer and it assures a more uniform flow of strained fluid. OPTIMIZE LENING utomatic cleaning allows you to optimize the cleaning cycle while you minimize maintenance labor costs. It provides the best cleaning action by simultaneously rotating the cleaning screen and operating the discharge valve which creates turbulence and enhances cleaning. balance must also be struck between the fluid discharge during a cleaning cycle and pumping efficiency across a clogged strainer. lean too soon and you waste some fluid in the discharge. lean too late and you waste power pumping across a clogged system. The Hellan utomatic Strainer enables you to tailor the cleaning cycle to your specific needs. You set a timer to clean whenever you choose. n actuated ball valve opens and closes the waste discharge port. To sense the clogging of the screen, a differential pressure switch monitors pressure drop across the strainer. The control panel synchronizes the screen drives and the discharge valve to achieve the optimum cleaning cycle. This cleans the screens without excessive discharge of the system fluid. IE STNRS Motors are available to meet or exceed the following IE standards: 1P21, 22, 23, 44, 54, 55, 56, 57, 65, 67 and 6. SELETION OF UTOMTI STRINER MOEL To select an automatic strainer and specify a model number, see the information on selecting and specifying a strainer model on pages 2-3. ESY ONVERSION TO UTOMTI OPERTION The strainer can be converted from manual to automatic operation in three easy steps. 1 UTOMTI STRINER SIZES utomatic strainers, in cast body construction, are available in 1-1/2" through 20" pipe sizes. The 1.5" 3" strainers (single screen) are furnished with one 1-1/2" discharge valve; the 4" through 12" (dual screens) are furnished with one 2" discharge valve; the 14" and 16" (4 screens) and 20" (6 screens) are furnished with two 2" discharge valves to obtain the optimum flushing action. utomatic strainers, in fabricated body construction, are available in 14" through 36" pipe sizes with two screens. The 14" and 16" are furnished with two 2" discharge valves; the 20" and 24" are furnished with two 3" discharge valves; the 30" and 36" are furnished with two 4" discharge valves to obtain the optimum flushing action. 1 2 ELETRIL OMPONENTS The basic components of the self-cleaning strainer are the differential pressure switch, the screen drive, the actuated discharge valve and the control panel. The drive replaces the handwheel and rotates each screen at approximately 17 RPM. 3

21 UTOMTI STRINER ONTROLS HN/OFF/UTOMTI The rotary H-O- selector switch allows for three modes of operation. In the Hand position, the screen drives and flush valve will be actuated until the switch is returned to off. In the OFF position, the self-cleaning cycle does not function. In the UTOMTI mode, there are three ways to initiate a cleaning cycle: 1. ifferential pressure switch. s the screen becomes clogged, the pressure drop will increase. t a preset point, a cleaning cycle will start. 2. Internal timer. n automatic interval between cleaning cycles can be set from 1 minute to 24 hours. 3. Manual start. momentary push-button on the control panel will start a cleaning cycle. SELETION OF UTOMTI STRINER ONTROL Strainer controls are ordered separately from the strainer. The selection of the control is based on both the number of motors (i.e.,, S & TS types have one motor; & W types have two motors; Q types have four motors and HH types have six motors) and their voltage. The voltage to the control panel must be the same as the motor voltage. To select a control panel and specify a model number, see the information on selecting and specifying a control panel model on pages 2-3. SYSTEM SFETY MONITORS The control panel is a constant indicator of the status of your system. For example, a panel light illuminates when power is applied to the strainer motor relay. If the strainer basket is not thoroughly cleaning during the normal cleaning cycle, the pressure drop continues to increase, causing the high pressure light to illuminate. The alarm is self-resetting when the differential pressure drop falls below the set point. 19 REMOTE OPERTIONS Manual ycle Start You may attach a normally open, momentary push-button to the control panel terminal strip. The H-O- switch must be in the UTOMTI position for the cycle to start. High Pressure larm Option set of contacts controlled by the high pressure alarm light is available as an option. Hand/Off/utomatic If you require these functions at a remote location, the control panel H-O- switch must be disconnected. IE STNRS NEM 12 controls panels meet or exceed IE IP10 through IP65. NEM 4 control panels meet or exceed IE IP66. NEM 4X control panels meet or exceed IE 529 IP66. ontrol panels are also available with IE components.
