05 - Seals to Suit Progressing Cavity Pumps

PCP seals are used extensively in the Coatings Kitchens area of Paper mills Seepex
where AESSEAL® have extensive sealing experience.

AESSEAL plc have designed ‘flared’ and ‘big bore’ seal housings in full
co-operation with leading PC pump manufacturers, and as acknowledged by
recognized institutions. These designs maximize radial and axial clearances,
encourage solids transfer away from the seal faces, reduce heat build up and
EXTEND SEAL LIFE.

The examples shown on these pages are a small example of the range of
PCP seals available from AESSEAL®.

AESSEAL® has a huge range of sealing solutions for ALL major PCP pump
manufacturers. This is contained in a dedicated guide to Sealing PCP Pump
applications.

Most designs are offered with the following features:

• Cartridge design for ease of installation.

• Often produced from dedicated castings to reduce cost.
• Maximum volume around seal faces to extend seal life.

Steam Nozzles

SNOZ™ Steam Nozzle Seal to suit Paper Machine drying

Cylinders.

AESSEAL® Drawing Number: 7110168

AESSEAL® Stock Code: 3SJ01/01

See case history 732 for further details.

Steam Nozzles are used on the drying cylinders in the paper

machine.

Steam is injected in through the stationary member of the

steam nozzle seal, and the rotary joint prevents steam leakage
to the atmosphere.

The AESSEAL® steam nozzle seal unit supplied is termed

SNOZ™ and inventoried in the stationary cast gland and
Stationary face only.

The Carbon rotary face is generally sourced on site, due to

site usage, however AESSEAL® can supply such seal faces if
required.
Equipment Characteristics
Typically this equipment has large shaft run-out and
eccentricity, with angular misalignment.
Equipment Manufacturers
In particular, Mondi / Sappi mills generally use these, and they
can be found on most Beloit or Beloit Warmsey equipment.

AESSEAL® have introduced a range of mechanical (S) Convertor II™
seals specifically designed for the arduous environments
encountered in the Pulp & Paper Industry. Cartridge Seal Designed to
Replace Packing
The Mechanical Seal range encompasses sealing solutions
for the equipment typically found in the industry, and includes
designs for Stock Process Pumps, Refiners, Screens, Mixers,
and Knotters, to name but a few.

These product ranges have been developed only after

extensive performance & field evaluation tests, conducted over
several years duration.

Innovative, Patented and Patent Pending products have

been introduced for specific targeted areas within the Pulp
& Paper industry. These include Exotic Alloy technology for
the Chemical and Bleaching mills, Axial movement seals for
refining equipment, and products with the ability to withstand
cyclic product pressures as encountered in hot dispersal
equipment.

AESSEAL® aims to provide such a high level of SERVICE that

our customers may never seek an alternative source of supply.

If rotating equipment bearings are inadequately protected, The LabTecta®66 is a non contacting, while rotating, bearing
equipment damage, loss of fluid and ultimately catastrophic seal that is designed for use in Oil Splash, Dry Running and
equipment failure may result. The contamination that causes Grease applications, on pieces of horizontal equipment.
bearings to fail is normally due to the use of low cost bearing
seals such as lip seals and labyrinth bushes. The solution is
to use the AESSEAL® MagTecta™ double mechanical seal, a The LabTecta®66 can also be used in the vast majority
product which is probably the most technologically advanced of existing Oil Mist applications that comply with the now
bearing protector in the world. superseded API 610 7th Edition requirements and where a
small quantity of Oil Mist escapes to atmosphere.
This seal is offered with the following extra features:
• Non contacting seal
• Double faces, double protection
• Ingress protection to IP55
• Universal design
• Easy to refurbish
• Compact housing will fit the majority of lip seal cavities
without the need for modification of equipment • Safe - Non sparking

• Rotary elastomer fits within existing lip seal cavity • Low cost
therefore our standard seal can be fitted on stepped shaft • No shaft wear
applications, reducing cost • Rotary elastomer fits within existing lip seal cavity
• Reversible housing to suit two housing sizes on one shaft therefore our standard seal can be fitted on stepped shaft
which reduces inventory and cost applications, reducing cost
• Suitable for use on Gear Boxes, Pumps, Rotary Valves, • Suitable for use on Gear Boxes, Pumps, Rotary Valves,

ISOS™
Inflatable Shut off seal

Most engineers will relate to the problems encountered when

installing or removing a radially divided mechanical seal from
rotating equipment.

However, the biggest single problem is that the whole system

has to be drained or isolated so that liquids do not pour out
when the seal is removed. This can sometimes take hours or
even days depending on the application - all lost production
time.

The AESSEAL® ISOS™, the Inflatable Shut Off Seal, solves

this major problem.

This seal is offered with the following extra features:

• Eliminates the need for pump shut off valves when changing
a seal and no pump re-priming is needed afterwards
• Fitted between the pump and seal it allows quicker and
easier changing of the mechanical seal without having to
drain equipment
• No re-priming of pumps needed after seal replacement
• Once inflated by a suitable and continuous supply it forms a
pressurized seal for zero product leakage
• For use in conjunction with Radially Divided Seals
