BENEFITS OF THE HELLAN STRAINER

CLEVELAND, OHIO USAPHONE (216) 206-4200 • FAX (216) 206-4242

REMOVE SOLIDS WITHOUT STOPPING THE FLOW

Instead of trapping solids in a basket which must then beremoved for frequent clean-outs, the Hellan Strainer removessolids from the fluid flow without stopping the flow or disas-sembling the strainer. A simple turn of the hand wheel (oractuation of the screen motor in automatic units) rotates thescreen against a scraper bar. Debris moves to a sump areawhere it is removed by periodic flushing.

LOW OPERATING COSTS

Removing solids from the screen takes about thirty seconds,compared to one or two hours for a basket strainer. Laborcosts can be completely eliminated with our automatic self-cleaning strainer.

SAFETY FOR EMPLOYEE PERSONNEL

The Hellan Strainer closed system protects personnel from contact with strained debris that may include contaminants orhazardous materials.

THE HELLAN STRAINER DESIGN PROVIDES SOLIDSREMOVAL WITHOUT INTERRUPTING THE FLUID FLOW

Instead of trapping solids in a basket which then must beremoved for frequent clean-outs, the Hellan Strainer removesthe solids from fluid without stopping the flow or disassembling the strainer. The sequence of operation is illustrated below.

❶ Fluid passes into the strainer and through a screen.

❷ A 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 thescreen’s outer surface.

❺ Debris moves to the sump area of the strainer where it isremoved by periodic flushing.

SPECIAL FEATURES PROVIDE CONVENIENCEAND HIGH PERFORMANCE.

❻ External scraper adjustment.

❼ O-rings at the screen cover plate and shaft provide atight seal while allowing operation at low torque.

❽ Backwash 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 Brush can replace solid scraper on all but 2" and 2-1/2"Angle-type and 2-1/2" and 3" D-type.

OPERATING FEATURES THAT PROVIDE REAL BENEFITS

• Eliminate downtime for solids removalThe Hellan Strainer allows users to eliminate solids anddebris from fluids without stopping the flow of the fluid.Processes requiring the fluid continue uninterrupted.

• Employees are not exposed to possible contaminatesDebris that may include contaminates and hazardousmaterials is removed from the fluid flow without disas-sembly of the strainer. Maintenance personnel and otheremployees do not come into contact with this debris.

• Minimum labor requirements for solids removalThe Hellan Strainer reduces the time required to removesolids from the fluid flow. Manually-operated modelsrequire only a periodic turning of the handwheel toremove solids. Labor and cleaning time is usually lessthen 30 seconds. Labor requirements can be completelyeliminated with automatic strainers that can be con-trolled by timers and/or pressure differential switches.

HOW TO SELECT A HELLAN STRAINER

CLEVELAND, OHIO USAPHONE (216) 206-4200 • FAX (216) 206-4242

There are seven application requirements that should beaddressed when selecting a specific Hellan Strainer model.Here are the considerations and options available for each requirement:

1 PERFORATION SIZE OF THE SCREENS

Hellan recommends that a screen perforation hole diameter be selected that is 40% to 60% of the diameter of the smallestorifice in the system. Selecting a smaller perforation thanrequired leads to unnecessary cleaning cycles and higher pressure drops during operation.

2 SIZE OF THE STRAINER

A) Existing Pipe Size MethodThis method is used when a Hellan Strainer is installed inan existing network of piping. Flow rate and the attendantpressure drop are within the application requirements.

In these situations, it is common practice to select a strainersize that matches the existing pipe size, i.e., an 8" strainerwould be selected for an installation with an existing 8" line.

B) Flow rate requirement versus pressure drop methodThis method should be utilized when selecting a strainer fora new application, or as a replacement strainer in existingsystems where a specific flow rate needs to be maintained.

Refer to the chart at right for flow rates of available strainersizes. Refer to the pressure drop versus flow rate charts forvarious size strainers, appearing on page 22.

C) High Concentration of SolidsFor removal of debris greater than 100 PPM, a solidseparator 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 minimumoperating pressure of 30 PSIG or 2 BAR. If operatingpressure is less, please contact the Hellan sales departmentfor assistance.

3 STRAINER CONSTRUCTION MATERIALS

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:

A) The operating pressure of the systemThe body material selected should have a pressure ratingthat is appropriate for the operating pressure of the system.(See page 17 for maximum pressure ratings for strainers ofvarious materials and flange types.)

B) The fluid to be strainedStandard cast iron models are commonly used for freshwater applications, while other materials are used to meetspecial needs: cast stainless steel for highly corrosive fluids,and bronze or monel for seawater applications.

C) The environment in which the strainer operatesA longer service life may be attained by specifying a construction mate that is appropriate for the service envi-ronment. Stainless steel should be considered for highlycorrosive environments and bronze for marine or otherapplications where salt air is present.

Hellan Strainers are available with two methods of operation:

A) Manual operation utilizing a hand wheelB) Automatic operation for utilizing motorized screens

Automatic operation normally utilizes a pressure differentialswitch, automatic discharge valve and a control panel. A separate model number for the control panel must also bespecified. (See pages 18 and 19 for information on automaticstrainers and control panel options.)

7 AFTER YOU HAVE SELECTED A HELLAN STRAINER

After you have reviewed the above considerations and haveselected a Hellan Strainer for your particular application, wesuggest two additional steps be taken before ordering:

A) Check dimensional compatibilityOnce a Hellan Strainer model has been selected, the dimen-sions for the model be reviewed to make sure that appropriateclearances are available in the system design to accommodatethe dimensions of the strainer.

Dimensional information for Hellan Strainers modelsappears on pages 23 through 53.

B) Specifying a model numberA model number for the selected strainer may be specifiedby referring to the model number guide on pages 54 and55. Remember that, when specifying an automatic strainer,a separate model number for the control panel must also be specified.

Please contact the factory at 888-4-HELLAN for assistance.

AUTOMATIC STRAINERS

Automatic Hellan Strainers are used whenever automaticself-cleaning of the strainer is required or advantageous.Under normal operating conditions, these units can performa complete cleaning cycle in just 15 seconds.

OPTIMIZED CLEANING

Automatic cleaning allows you to optimize the cleaning cyclewhile you minimize maintenance labor costs. It provides thebest cleaning action by simultaneously rotating the cleaningscreen and opening the discharge valve which creates lessdebris out.

A balance must also be struck between the fluid discharge during a cleaning cycle and pumping efficiency across aclogged strainer. Clean too soon and you waste some fluid inthe discharge. Clean too late and cleaning may be impaired.

The Hellan Automatic Strainer enables you to tailor the cleaning cycle to your specific needs. You set a timer to cleanwhenever you choose.

Cleaning should be performed in time to keep pressure drop lessthan four times the clean pressure drop. Not to exceed 8 PSID.

AUTOMATIC STRAINER SIZES

Automatic strainers, in cast body construction, are available in 1-1/2" through 20" pipe sizes. The 1.5"– 3" strainers (singlescreen) are furnished with one 1-1/2" discharge valve; the 4"through 12" (dual screens) are furnished with one 2" dis-charge valve; the 14" and 16" (4 screens) and 20" (6 screens)are furnished with two 2" discharge valves to obtain the optimum flushing action.

Automatic strainers, in fabricated body construction, areavailable in 14" through 30" pipe sizes. The 14" and 16" arefurnished with two 2" discharge valves; the 20" and 24" arefurnished with two 3" discharge valves; the 30" is furnishedwith two 4" discharge valves to obtain the optimum flushing action.

ELECTRICAL COMPONENTS

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.

An actuated ball valve opens and closes the waste dischargeport. To sense the clogging of the screen, a differential pressureswitch 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.

IEC STANDARDS

Motors are available to meet or exceed the following IEC standards: 1P21, 22, 23, 44, 54, 55, 56, 57, 65, 67 and 68.

SELECTION OF AUTOMATIC STRAINER MODEL

To select an automatic strainer and specify a model number,see the information on selecting and specifying a strainermodel on pages 52-53.

EASY CONVERSION TO AUTOMATIC OPERATION

The strainer can be converted from manual to automatic operation in three easy steps.

AUTOMATIC STRAINERS

HAND/OFF/AUTOMATIC

The rotary H-O-A selector switch allows for three modes ofoperation. In the “Hand” position, the screen drives and flushvalve will be actuated until the switch is returned to off.

In the “OFF” position, the self-cleaning cycle does not function.

In the “AUTOMATIC” mode, there are three ways to initiate a cleaning cycle:

1. Differential pressure switch. As the screen becomes clogged,the pressure drop will increase. At a preset point, a cleaningcycle will start.

2. Internal timer. An automatic interval between cleaningcycles can be set from zero to 100 hours.

3. Manual start. A momentary push-button on the controlpanel will start a cleaning cycle.

SYSTEM SAFETY MONITORS

The control panel is a constant indicator of the status of yoursystem. For example, a panel light illuminates when power isapplied 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 dropfalls below the set point.

REMOTE OPERATIONS

Manual Cycle StartYou may attach a normally open, momentary push-button tothe control panel terminal strip. The H-O-A switch must be inthe AUTOMATIC position for the cycle to start.

High Pressure Alarm OptionA set of contacts controlled by the high pressure alarm light isavailable as an option.

Hand/Off/AutomaticIf you require these functions at a remote location, the controlpanel H-O-A switch must be disconnected.

IEC STANDARDS

NEMA 12 controls panels meet or exceed IEC IP10 through IP65.

NEMA 4 control panels meet or exceed IEC IP66.NEMA 4X control panels meet or exceed IEC 529 IP66.Control panels are also available with IEC components.

SELECTION OF AUTOMATIC STRAINER CONTROL

Strainer controls are ordered separately from the strainer. Theselection of the control is based on both the number of motors(i.e., “AA”, “SA” & “TSA” types have one motor; “DA” & “WDA”types have two motors; “QA” types have four motors and “HH”types have six motors) and their voltage. The voltage to thecontrol panel must be the same as the motor voltage. To selecta control panel and specify a model number, see the infor -mation on selecting and specifying a control panel model onpage 53.

EXTERNAL SCRAPER ADJUSTMENT

As an option, TS and D-type Hellan strainer are equipped toallow for adjustment of scrapers or brushes from outside thebody without opening the pressure vessel. The accompanyingfigure illustrates this feature. The scraper or brush is held inplace by two pulling pins to which it is bolted. The outwardend of each pulling pin penetrates the pressure vessel throughthe scraper support cover. Both pulling pins are o-ring sealed.The outward ends of the pulling pins are also threaded allow-ing pulling screws to be tightened against the pulling cover.The scraper or brush is pulled against a jack screw which holdsit in the correct location relative to the screen surface.

PULLING SCREW

Once the scraper or brush is adjusted at the factory, it can bereadjusted to compensate for wear. Brushes should be set tobear against the wedge wire screen surface. Scrapers should be set so that they are .005 to .010 inches away from theperforated screen surface. To accomplish this adjustment, thepulling screws should be loosened and then the scraper orbrush should be moved inward until it is against the screensurface. This is done by turning the jack screw clockwise. Care 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 pullingscrews should be tightened securing the brush against the jack screw. If a scraper is in use, the jack screw should berotated approximately 45 degrees counterclockwise. Then the pulling screws should be tightened securing the scraperagainst the jack screw.

PRESSURE SWITCH AND THREE WAY BALL VALVE

The pressure switch is used to initiate a cleaning cycle whenthe differential pressure across the strainer reaches a pre setlevel. It is used to indicate when the differential pressure is toohigh by an indicator light on the control panel. The pressureswitch has two switches with contacts that close when theseevents take place. The levels at which these contacts close canbe adjusted by turning the marked adjustments on each endof the electrical housing of the switch. The pressure that existsacross the pressure switch can be read from a 0-25 psid gaugeon the switch assembly. The points are factory pre set at 4 psid and 8 psid respectively. However, there is no means todetermine these set points if they are moved from the factorypre sets. This is the purpose of the three way ball valve. As canbe 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 valveis horizontal, the ends of the valve are connected and nopressure exists across the valve. However, as the handle isslowly rotated clockwise, the valve port connected to thestrainer is restricted and the valve port pointed down allowsthe Lo port of the pressure switch to vent. As this happens, the gauge reading will slowly increase. The pressure levels atwhich the set-points are set is determined by viewing thepressure reading at which the cleaning cycle initiates and thehigh pressure indicator on the control panel illuminates. Todo this the pressure in the strainer must be greater that thehigh set-point of the pressure switch.

FLOW RATE VS PRESSURE DROP

The accompanying table lists the flow rate (Cv), in gallons perminute of water that will result in 1.0 pounds per square inchof differential pressure across the size and type of strainershown in the left-hand column with the screen opening shownacross the top.

PRESSURE LOSS CACULATION USING CV FACTOR

Standard Units Metric Units

dP � [ Q ]2dP � [ Q ]2

(133.6)Cv Cv

Q = Flow in GPM Q = Flow in M3/hrCv = Flow Coefficient Cv = Flow CoefficientdP = Pressure Drop in psi dP = Pressure Drop in kPa

The pressure loss across a strainer can be calculated using the system’s flow rate and the Cv factor for that strainer.
