BENEFITS OF THE HELLAN STRAINER


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.

HIGH QUALITY CONSTRUCTION

Hellan Strainers are designed and built to ANSI/ASQCStandard Q94-1987. Each strainer is proof pressure tested to150% MAWP, per ASME standards, before shipment. QualityAssurance and manufacturing systems are registered for compliance with ISO-9001 International Standard.

UNIQUE OPERATING FEATURES


6

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 Large inspection ports, sealed with O-rings, permit easy,external adjustment of the scraper bar. Multiple screenmodels size 4" and larger, plus 3" single screen models.

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

➑ Backwash system is available to remove debris from screen.

➒ Eductor is available at discharge for low-pressure applications.

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


There are six 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 pages 54 through 81.

3 STRAINER CONSTRUCTION MATERIALS

Hellan Strainers are available with cast bodies constructed iniron, 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 thematerial of the body. (See pages 14 and 15 for standard materi-als of construction for strainers of various body materials.)

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 15 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 material that is appropriate for the serviceenvironment. Stainless steel should be considered for highlycorrosive environments and bronze for marine or otherapplications where salt air is present.

AUTOMATIC STRAINERS


18

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. This meansthat only a small amount of fluid is needed to flush solidsfrom the strainer and it assures a more uniform flow ofstrained fluid.

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 operating the discharge valve which creates turbulence and enhances cleaning.

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 you waste power pumpingacross a clogged system.

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

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 36" pipe sizes with two screens. The14" 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 obtainthe 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 82-83.

EASY CONVERSION TO AUTOMATIC OPERATION

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

AUTOMATIC STRAINER CONTROLS


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 1 minute to 24 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 light to illuminate.

The 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 informa-tion on selecting and specifying a control panel model onpages 82-83.
