INSTALLATION AND OPERATING INSTRUCTIONS FOR

BOLL DUPLEX FILTERS

1.

Description

Duplex filters which can be changed over consist of two filter housings operated in
parallel by a two-stage change-over device. The filter housings are designed to
meet the current regulations for a particular pressure range, the filter elements are
provided with an appropriate safety factor for the differential pressures indicated on
the filter nameplates. The maximum differential pressure for filter meshes is 0.8 bar,
for micro-cartridges 2 bar.
Duplex filters are used in cases where the contaminated filter elements have to be
regenerated without interrupting the filtration process.

The change-over devices, i.e. cylindrical plugs, ball valves or double-stage change-
over valves, permit change-over without pressure shocks. Owing to the design of
the change-over device it is not possible for both filter chambers to be switched off
at the same time.

2.

Installation

When the filter is attached to its foundation, the filter housing must be free from
strain. The same applies to the connected piping. The connections for the inlet and
outlet depend on the strainer element used (see works standard WN 211). Pay
attention to the arrow marked on the housing.

Heated filters with shut-off devices:

- Special equipment needed for heatable filters -

Heating of the filter serves to offset the heating loss at the filter during the filtration process
or before start-up of the plant to heat the liquid in the filter.

According to the AD Information Sheets, the filter housings
are only rated for internal overpressure. Additional external
forces and moments at the connection flanges of the filter are
to be avoided (possibly support feed lines).

a) Steam-heated

filters:

Safety valves for the filter chamber set to operate at the
relief pressure which is 10 % above the max. admissible
operating pressure of the filter housing.

b)

Electrically heated filters:
Thermostats which cut off the power supply to the
heating element at a max. admissible temperature of
150 °C in the filter chamber and one safety valve per
filter pot.

3.

Start-up

3.1 Pressure filters (> 0.1 bar pressure in the filter)

Set the change-over device to the mid-position, both chambers in service, pressure
equalising cock open.
Open air vents of both chambers (with venting screws only about 1 turn).
Start plant up slowly.
Close air vents when the air has escaped and the liquid has started to emerge.
Isolate one filter chamber by operating the change-over device, leave the pressure
equalising cock open; while one of the filter chambers is being used for filtering, the
isolated chamber is on stand-by until the admissible differential pressure has built up
as a result of clogging.
At a differential pressure of 0.8 bar in filter meshes or 2 bar in micro-cartridge filters
change over to the clean filter chamber as follows:

Cleaning

• Check that the pressure equalising cock is open and whether the stand-by

chamber is full by briefly opening the air vents.

• Change over.
• Close pressure equalising cock.
• Open the air vent on the isolated filter; this releases the liquid pressure and it is

then possible to check whether the change-over device has cut off the flow to the
filter chamber.
In contrast to the change-over and ball valve devices, complete sealing is not
possible with the plug-type system; by opening the sludge outlet, liquid leaking
during the cleaning process can be drained off.

• Remove the housing cover from the isolated filter chamber.
• Drain liquid down to the strainer base in the case of basket strainers; drain filter

housing completely in the case of mantle strainers, cartridge strainers and micro-
cartridges.

• Remove the filter element vertically upwards.

It is imperative for the pressure equalising cock to only
remain closed in the cleaning phase so that there is no
inadmissible pressure build-up through the thermal
expansion of the medium in the isolated chamber.

In smaller duplex filters without pressure compensation the
heat expansion of the medium is so low that there is no
risk to the components.

• Clean filter element (see operating instructions "Strainer cleaning"); renew

disposable elements and install them in the filter.

• Before mounting the cover, check that the seal is in perfect condition and seated

properly.
It is imperative to renew seals which have become hardened and deformed.
Screw cover on, the air vent remains open.
Open pressure equalising cock or, if not installed, set change-over device to mid
position until the air has been vented.

• Close air vent. This filter is now on stand-by.

3.2

Suction filters (< 0.1 bar pressure in filter)

Recommended container filling for suction filters

drain

filling line

• Fill and vent both filter halves.
• Isolate one of the filters with the change-over device, close pressure equalising

cock.

• Start up the plant. While one filter chamber is being used for filtration, the isolated

chamber is on stand-by. When the differential pressure across the filter reaches
the maximum allowed by the pump suction head, a change-over to the other filter
half must be made.

• Open pressure equalising cock.
• Change over.
• Close pressure equalising cock.
• Open air vent on the isolated filter half.

Air may be drawn in if the level drops.

• Dismantle the housing cover from the isolated filter half.
• Drain liquid down to the strainer base.
• Remove filter element vertically upwards.
• Clean filter element (see operating instructions "Strainer cleaning"). Renew

disposable elements and install in the filter.

• Fill filter housing (see Fig.).
• Before mounting the cover, check that the seal is in perfect condition and seated

properly.
It is imperative to renew seals which have become hardened and deformed.
Close air vent.

• The cleaned filter half is ready on stand-by. This procedure is to be repeated from

section as and when required.

4.

Servicing:
Servicing of the duplex filter comprises checking and, if necessary, renew the
seals and filter elements. If the filter is provided with rust-inhibiting paint, touch up or
repaint as and when required.
When filtering cooling water or media which may cause sedimentation on the
change-over device, it is advisable to activate the change-over device as often as
possible and at regular intervals in order to prevent clogging.

BOLL & KIRCH assumes no liability for any mistakes by any misuse of the product.

We reserve the right to change this description without any prior notice!

It is not permitted to fill the filter against the

indicated flow direction of the filter elements.

CLEANING THE MULTI-MANTLE FILTER ELEMENTS

1.

The multi-mantle filters consist of up to 6 nested filter elements.
Fields of application are filter meshes < 200 µm.
In order to prevent flow short-circuits, the joins of the individual components are sealed with O-rings.

2.

The admissible differential pressures depend on the multi-mantle filter diameter:

3.

Accessories of the filter element

The following items can be
supplied as accessories:

•

magnetic primary filter (19)

•

magnetic secondary filter (20)

4.

Maintenance

4.1

Clean and inspect multi-mantle filter elements at regular intervals. The length of these intervals
depends on the amount of dirt that has accumulated.

4.2

Carry out the first cleaning operation immediately after the installation has been flushed. A rising
pressure loss is a sign of increasing dirt accumulation.
The differential pressure is not to exceed 0.8 or 1.2 bar (suitable monitoring appliances are available
from BOLL & KIRCH).

5.

Cleaning

5.1

Shut off single filter or change over duplex filter. Release pressure from the filter housing by undoing
the venting screw and remove the housing cover. Open the drain screw in the filter base and drain
contents completely. Slacken the self-locking nut (4) on the central tie rod (5) and lift out the inner
filter with the lifting eye (18). Lift the remaining filter elements out individually by gripping the inside of
the filter ring.

5.2

Place the individual filter elements into containers with cleaning agent and brush off with not too hard
a brush (e.g. nylon brush).

5.3

Now blow compressed air at about 4 bar through the filter element cleaned in the above manner
from the clean side. To this end insert the cleaning gun type 5.02 (22) into the openings located in
the upper filter ring and blow through the filter surface from the inside with up and down motions.

5.4

In the case of persistent dirt or paint encrustation, place the filter into a with cleaning agent (to sheet
KV 349) and allow to soak for up to 4 hours. Make sure that the filter is not completely immersed but
that the upper ring remains free. This prevents dirt from reaching the clean side.

5.5

Remove filter and continue to treat as described under points 5.2 and 5.3.

5.6

If necessary, repeat points 5.4 and 5.5.

5.7

For final cleaning, rinse the filter in clean cleaning fluid (e.g. petroleum ether, paraffin, hot water or
similar) and blow through again. Then check fabric for cleanness and damage. Assess cleaning
effect by holding the filter element against the light. Use a torch for finer fabrics. If the light
penetrates evenly, the fabric has been cleaned well.

5.8

Check all seals including cover seals. Seals which have become hard and deformed must be
renewed without fail.

Before you open the filter chambers, observe the operating instructions for

single and duplex filters.

5.9

Insert the individual elements in the filter housing. Place the self-locking hexagonal nut, item 4, on
the central anchor and tighten using the tightening torque depending on the thread size.

6.

Cleaning appliances

6.1

2 cleaning containers.

6.2

Cleaning gun, type 5.02.

6.3

10 mm spanner.

6.4

Compressed air connection, max. 6 bar.
For particularly convenient and thorough filter cleaning we recommend our cleaning trolley type 5.04
with cartridge filter, pump and cleaning gun.

COVER SECURING DEVICE FOR DOUBLE FILTERS

The function of the cover securing

device is to prevent the uncontrolled

excape of lubricantes and fuels in the

case of operating errors. The cover

plate (2) covers a minimum number of

cover screws (3), so that the cover (1)

cannot be removed with out actuating

the venting facility (4).

The filter chamber is relieved through

the venting screw (4). With the correct

switching position, the service pressure

of the filter chamber falls immediately

and hardly any fuel excapes. Otherwise,

the venting screw is immediately closed

and the fuel discharge is limited.

BOLL & KIRCH assumes no liability for any mistakes due to misuse of the product.
