BENEFITS OF THE HELLAN STRAINER
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. A 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 OPERATING COSTS
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.
SAFETY FOR EMPLOYEE PERSONNEL
The Hellan Strainer closed system protects personnel from
contact with strained debris that may include contaminants or
hazardous materials.

OPERATING FEATURES THAT PROVIDE REAL BENEFITS
• 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.

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 BAR. If operating
pressure is less, please contact the Hellan sales department
for assistance.
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 PERFORATION SIZE OF THE SCREENS
3 STRAINER CONSTRUCTION MATERIALS
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.
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.
2 SIZE OF THE STRAINER
The selection of a body material depends on three criteria:
A) 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.
B) 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.
C) High Concentration of Solids
For removal of debris greater than 100 PPM, a solid
separator is recommended upstream of the Hellan strainer.
A) 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.)
B) 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.
C) The environment in which the strainer operates
A 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.

7 AFTER YOU HAVE SELECTED A HELLAN STRAINER
After you have reviewed the above considerations and have
selected a Hellan Strainer for your particular application, we
suggest two additional steps be taken before ordering:
A) Check dimensional compatibility
Once a Hellan Strainer model has been selected, the dimensions for the model be reviewed to make sure that appropriate
clearances are available in the system design to accommodate
the dimensions of the strainer.
Dimensional information for Hellan Strainers models
appears on pages 23 through 53.
B) Specifying a model number
A model number for the selected strainer may be specified
by referring to the model number guide on pages 54 and
55. 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 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 CLEANING
Automatic 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.
A balance must also be struck between the fluid discharge
during a cleaning cycle and pumping efficiency across a
clogged strainer. Clean too soon and you waste some fluid in
the 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 clean
whenever you choose.
Cleaning should be performed in time to keep pressure drop less
than four times the clean pressure drop. Not to exceed 8 PSID.
An 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.
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 strainer
model on pages 52-53.
EASY CONVERSION TO AUTOMATIC OPERATION
The strainer can be converted from manual to automatic
operation in three easy steps.
AUTOMATIC STRAINER SIZES
18
Automatic strainers, in cast body construction, are available
in 1-1/2" through 20" pipe sizes. The 1.5"– 3" strainers (single

AUTOMATIC STRAINERS
HAND /OFF /AUTOMATIC
SELECTION OF AUTOMATIC STRAINER CONTROL
The rotary H-O-A 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.
Strainer controls are ordered separately from the strainer. The
selection 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 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
page 53.
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 cleaning
cycle will start.
13”
2. Internal timer. An automatic interval between cleaning
cycles can be set from zero to 100 hours.

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

EXTERNAL SCRAPER ADJUSTMENT
As 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. Both 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.
A
Once the scraper or brush is adjusted at the factory, it can be
readjusted to compensate for wear. Brushes 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.
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 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.

PRESSURE SWITCH AND THREE WAY BALL VALVE
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. As can
be seen from the accompanying figure, the ball valve is
DP SWITCH/GAUGE
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. As 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.
