High Duty and Slurry Seals
Type 5840 Type 5860 Type 5870
Description Type 5840 is a single cartridge seal that includes
many of the advantages associated with heavy
duty seal design assembled into a cost effective
package for the volume requirements associated
with general mineral processing duties. It is
manufactured from materials resistant to abrasive
and/or chemical attack, to provide long service
life in hostile environments. The absence of
dynamic secondary seals means that there is
no shaft fretting or damage and no hang-up of
primary seal faces.
Type 5860 is a ruggedly constructed, OD-
pressurized, single O-ring pusher slurry seal
designed specifically for use in heavy duty slurry
pumps, mixers and other rotating equipment for
the mining and mineral industries where heavy ore
slurries are processed. Replaceable, hard alloy

(Type 7828, 7848)
Description Type 32 is a single, contacting
dry-running, O-ring pusher
component seal designed for
pharmaceutical and chemical
processing mixer applications.
As no lubrication equipment is
required, Type 32 seals are highly
economic solutions.
Type 32i features a unique noise
reduction technology and Type
32D can be used on ATEX cat. 1
equipment without additional
monitoring devices.
Type 32GL is designed for corrosive
mixer applications, specifically
those found on glass-lined mixers
and feature a composite sleeve.
A dual back-to-back version can
also be supplied.
Type CK Series vessel seals are dual
cartridge seals for top entry vessel and
agitator equipment. While their standard
versions are compliant to vessel seal
standard DIN 28138, adaptations to non-
DIN equipment are possible on request.
As required by DIN, type variants are
available without or with integrated radial
bearing, as well as those applicable to
glass-lined equipment. Seal type CK725,
CK726 and CK736 are compact units with
unbalanced, liquid-lubricated seal faces
for general duties. Contacting dry-
running versions are available on request.
Type CK728 and CK738 feature balanced
faces for heavy duty conditions.
Furthermore, both seal types are
available as liquid-lubricated, contacting
dry-running or non-contacting gas-
lubricated design, the latter for high-
purity applications in pharmaceutical
industries. All CK seals are compliant
with European ATEX legislation.
The first choice for ultra-clean
pharmaceutical and biotech
applications, these seals meet
Qualified Hygienic Design (QHD)
requirements to enable the cleaning
and sterilization of the product-
wetted parts with the seal in place
(CIP, SIP). Different versions of Type
5280 Series are suitable for different
vessel materials: Type 5280 for steel,
Type 5281 for glass-lined and Type
5282 for special alloy vessels. Each
type is available as liquid-lubricated,
contacting dry-running or non-
contacting gas-lubricated versions
for high-purity applications. The
special inboard seal design allows
the application on top, side and
bottom entry vessels. All versions
are suitable for operation in
potentially explosive atmospheres
(ATEX cat. 1–3).
Type 7800 Series is a modular, dual-
pressurized, back-to-back, O-ring
pusher cartridge seal designed
for mixer applications. Compact
standard versions, including a
bearing option, are available from 1
to 8 inches. Type 7848 is available
as a liquid-lubricated or contacting
dry-running version, whereas Type
7828 is a non-contacting gas-
lubricated design for high-purity
applications. Where reduced barrier
gas consumption is desirable, Type
7828GD is a hybrid design that offers
a combination of non-contacting
dry-running seal faces inboard
and contacting dry-running seal
faces outboard.

Commercial OEM Seals Type 2100 Type 502 Type 1/1A/1B/2/2B
Description Simple mechanical seals, including
Type 6, 6A, 21 and 2106, designed
to serve the high volume machinery
market. Some are suitable for
shafts with large misalignments
and run-outs. This is an economic
solution ideal for general
purpose applications.
A compact, single spring elastomer
bellows. The unitized design makes
it easy to fit. Design conforms
to DIN 24960 and exists in three
working lengths. Large flexibility
makes it ideal for shafts with axial
play and run-outs. Positive key
drive protects bellows from
torsional strain.
Type 502 is a full convolution
elastomeric bellows seal designed
for confined spaces and limited
gland depths. Self aligning feature
compensates for excessive shaft
end-play and run-out.
These are multi-purpose non-
pusher elastomer bellows seals
for industrial applications. Designs
are available in single, double
and balanced arrangements. The
bellows technology is available as
a cartridge in Type 5611 seal range.
Incorporating a spring adapter
creates a low profile, enabling it
to fit small cross section stuffing
boxes. Mechanical drive prevents
shaft damage and eliminates
overstressing of bellows. The seal
head is self-aligning, automatically
adjusting for abnormal shaft end-
play run-out, primary ring wear
and equipment tolerances. Non-
clogging, single-coil spring is not
affected by build-up of solids.

PR 52/53A & PA 53B PL 54/55 PG 72/74 WCV/WCH
Control Panel
Type 2800
Description These reservoir-based seal support
systems are designed for API
Plan 52/53A and 53B applications
to support unpressurized and
pressurized dual seals. Circulation
to buffer or barrier fluid is achieved
with a pumping ring (or optional
circulating pump). A range of heat
exchangers can be packaged with
this system.
PL 54/55 lubrication systems
provide a positive flow and
pressure of pressurized
or unpressurized barrier/
buffer fluid to dual seals.
This seal support system
type is typically preferred
where flow and heat removal
capacity exceeds that of
API Plan 52 or 53 seal
support systems.
PG 72/74 systems are used
to provide a clean, regulated
gas supply to either a dual
unpressurized or pressurized
seal arrangement. A gas,
typically nitrogen, is
introduced in the area
between the inner and
outer seals, thus preventing
fugitive emissions from
escaping to the atmosphere.
These water-cooled heat
exchangers, either vertical
or horizontal configurations,
may be applied where water
is readily available and may
be packaged together with
seal support systems when
additional cooling is needed.
Simple gas control panel
suitable for all 2800/
2874 seals.

GR1/1C and GR2/2C Safeunit Ultima ABC Cyclone Separator
Description These stainless steel vessels
(without or with internal cooling
coil) are designed for general
industry applications and provide
buffer/barrier fluid to a dual-
seal arrangement.
Safeunit Ultima is specially
designed to control seal water flow
and pressure in extreme conditions.
This makes it ideal for the extreme
applications found in pulp, paper
and chemical industry processes,
plus a wide variety of mining and
general industrial uses.
Air-cooled heat exchangers may
be applied when water is not
available, or required heat removal
can be achieved with an air-cooled
heat exchanger. Air-cooled heat
exchangers are available in a range
of finned tube designs, including
electrically-driven air blast models.
Cyclone separators (API Plan 31)
are incorporated in the flush line
from discharge of the pump. This
separator does not require cleaning
and is designed to remove solids,
providing a clean flush stream back
to seal chamber.

Liquid Filtration Seal Gas Filtration Fuel Gas Filtration Simulation
Description Liquid filters are typically used on
all oil and water duties and can
be applied to almost any liquid
application. Duplex filters are
recommended to ensure adequate
filtration of the process flow while the
filter element is changed.
Almost every centrifugal compressor
uses dry gas seals to contain the
high-pressure gas, whether
it is on a high-pressure re-injection
duty or on a low-pressure pipeline.
Features include:
• Coalescing stages to remove liquids
in the gas stream ensuring the gas
is suitably dry
• Double block and bleed arrangement
Throughout the oil and gas and power
generation industries, natural gas
has become the preferred fuel for
providing motive power. Effective
filtration systems help ensure the
demands of modern engines are met
by providing clean, dry gas. Failure
to provide this can quickly cause
a reduction in efficiency or worse.
Indufil fuel gas filtration units are
individually tailored to maximize
reliability regardless of the
supply gas.
Fluid Dynamic Analysis
Seebach has extensive experience in
the simulation of fluid and media flow
characteristics. Utilizing the simulation
process we can optimize existing
systems or design new systems
optimized for specific applications.
Seebach is upgrading elements and
