3 ENEFITS OF THE HELLN STRINER REMOVE SOLIDS WITHOUT STOPPING THE FLOW Instead of trapping solids in a basket which must then be removed for frequent clean-outs, the Hellan Strainer removes solids from the fluid flow without stopping the flow or disassembling the strainer. simple turn of the hand wheel (or actuation of the screen motor in automatic units) rotates the screen against a scraper bar. Debris moves to a sump area where it is removed by periodic flushing. LOW OPERTING OSTS Removing solids from the screen takes about thirty seconds, compared to one or two hours for a basket strainer. Labor costs can be completely eliminated with our automatic self-cleaning strainer.

8 UNIQUE OPERTING FETURES THE HELLN STRINER DESIGN PROVIDES SOLIDS REMOVL WITHOUT INTERRUPTING THE FLUID FLOW Instead of trapping solids in a basket which then must be removed for frequent clean-outs, the Hellan Strainer removes the solids from fluid without stopping the flow or disassembling the strainer. The sequence of operation is illustrated below. ❼ ❶ ❹ ❸ ❻ ❶ Fluid passes into the strainer and through a screen. ❷ deflection rib protects the screen from large objects. ❸ The screened fluid flows out of the strainer and into service. ❹ Rotating the screen, by either handwheel or motor, moves the outer screen surface against a scraper bar. The scraper bar removes collected debris from the screen s outer surface. ❺ Debris moves to the sump area of the strainer where it is removed by periodic flushing. ❷ ❺ 6 SPEIL FETURES PROVIDE ONVENIENE ND HIGH PERFORMNE. ❻ External scraper adjustment. ❼ O-rings at the screen cover plate and shaft provide a tight seal while allowing operation at low torque. ❽ ackwash system is available to remove debris from screen on low pressure applications except 2", 2-1/2" and 3" angle types and 3" D-type. ❾ Eductor is available at discharge for low-pressure applications. ❿ rush can replace solid scraper on all but 2" and 2-1/2" ngle-type and 2-1/2" and 3" D-type. TO DRIN OPERTING FETURES THT PROVIDE REL ENEFITS Eliminate downtime for solids removal The Hellan Strainer allows users to eliminate solids and debris from fluids without stopping the flow of the fluid. Processes requiring the fluid continue uninterrupted. Employees are not exposed to possible contaminates Debris that may include contaminates and hazardous materials is removed from the fluid flow without disassembly of the strainer. Maintenance personnel and other employees do not come into contact with this debris. Minimum labor requirements for solids removal The Hellan Strainer reduces the time required to remove solids from the fluid flow. Manually-operated models require only a periodic turning of the handwheel to remove solids. Labor and cleaning time is usually less then 30 seconds. Labor requirements can be completely eliminated with automatic strainers that can be controlled by timers and/or pressure differential switches.

13 HOW TO SELET HELLN STRINER There are seven 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 8" strainer would be selected for an installation with an existing 8" 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 page 22. ) High oncentration of Solids For removal of debris greater than 100 PPM, a solid separator is recommended upstream of the Hellan strainer. D) Discharge Side of Pump It is recommended that a Hellan strainer be installed on the discharge side of a centrifugal pump with a minimum operating pressure of 30 PSIG or 2 R. If operating pressure is less, please contact the Hellan sales department for assistance. 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 such as Super Duplex are available by special order. The material used for internal components depends on the material of the body. 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 17 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 mate 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 Decimal Metric Mesh Micron Inches Metric Mesh Micron 1/4".250" 6.35 mm " 0.38 mm /16".188" 4.77 mm " 0.23 mm /8".125" 3.18 mm *.007" 0.18 mm /32".094" 2.38 mm *.005" 0.13 mm /16".063" 1.59 mm *.004" 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 18 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. OPTIMIZED 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 opening the discharge valve which creates less debris out. 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 cleaning may be impaired. The Hellan utomatic Strainer enables you to tailor the cleaning cycle to your specific needs. You set a timer to clean whenever you choose. leaning should be performed in time to keep pressure drop less than four times the clean pressure drop. Not to exceed 8 PSID. 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 30" pipe sizes. The 14" and 16" are furnished with two 2" discharge valves; the 20" and 24" are furnished with two 3" discharge valves; the 30" is furnished with two 4" discharge valves to obtain the optimum flushing action. 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 STNDRDS Motors are available to meet or exceed the following IE standards: 1P21, 22, 23, 44, 54, 55, 56, 57, 65, 67 and 68. SELETION OF UTOMTI STRINER MODEL To select an automatic strainer and specify a model number, see the information on selecting and specifying a strainer model on pages ESY ONVERSION TO UTOMTI OPERTION The strainer can be converted from manual to automatic operation in three easy steps. 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 STRINERS HND/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. Differential 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 zero to 100 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; D & WD 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 infor - mation on selecting and specifying a control panel model on page 53. SERIL NUMER PLTE WRNING PLTE 13 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 alarm light to illuminate. This alarm is self-resetting when the differential pressure drop falls below the set point. POWER ON YLE STRT LENING YLE IN PROGRESS OFF HND UTO HIGH PRESSURE 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. TRNSFORMER FTORY WIRED FOR 230 OR 460 VOLTS. NONE FOR 115 VOLTS.

22 EXTERNL SRPER DJUSTMENT s an option, TS and D-type Hellan strainer are equipped to allow for adjustment of scrapers or brushes from outside the body without opening the pressure vessel. The accompanying figure illustrates this feature. The scraper or brush is held in place by two pulling pins to which it is bolted. The outward end of each pulling pin penetrates the pressure vessel through the scraper support cover. oth pulling pins are o-ring sealed. The outward ends of the pulling pins are also threaded allowing pulling screws to be tightened against the pulling cover. The scraper or brush is pulled against a jack screw which holds it in the correct location relative to the screen surface. Once the scraper or brush is adjusted at the factory, it can be readjusted to compensate for wear. rushes should be set to bear against the wedge wire screen surface. Scrapers should be set so that they are.005 to.010 inches away from the perforated screen surface. To accomplish this adjustment, the pulling screws should be loosened and then the scraper or brush should be moved inward until it is against the screen surface. This is done by turning the jack screw clockwise. are should be taken not to over tighten the jack screw. The pulling screws should be turned clockwise until they just bear on the pulling cover. If a brush is in use, the pulling screws should be tightened securing the brush against the jack screw. If a scraper is in use, the jack screw should be rotated approximately 45 degrees counterclockwise. Then the pulling screws should be tightened securing the scraper against the jack screw.

23 PRESSURE SWITH ND THREE WY LL VLVE The pressure switch is used to initiate a cleaning cycle when the differential pressure across the strainer reaches a pre set level. It is used to indicate when the differential pressure is too high by an indicator light on the control panel. The pressure switch has two switches with contacts that close when these events take place. The levels at which these contacts close can be adjusted by turning the marked adjustments on each end of the electrical housing of the switch. The pressure that exists across the pressure switch can be read from a 0-25 psid gauge on the switch assembly. The points are factory pre set at 4 psid and 8 psid respectively. However, there is no means to determine these set points if they are moved from the factory pre sets. This is the purpose of the three way ball valve. s can be seen from the accompanying figure, the ball valve is connected between the Lo port of the pressure switch and the Lo port of the strainer. When the handle of the ball valve is horizontal, the ends of the valve are connected and no pressure exists across the valve. However, as the handle is slowly rotated clockwise, the valve port connected to the strainer is restricted and the valve port pointed down allows the Lo port of the pressure switch to vent. s this happens, the gauge reading will slowly increase. The pressure levels at which the set-points are set is determined by viewing the pressure reading at which the cleaning cycle initiates and the high pressure indicator on the control panel illuminates. To do this the pressure in the strainer must be greater that the high set-point of the pressure switch.
