With operations in six continents, AESSEAL® is the world’s 4th largest supplier of mechanical seals, achieving growth through exceptional customer service and innovative products that provide real customer benefits.

For every seal developed by AESSEAL®, we use state-of-the-art computational facilities and numerical tools to design and optimize seal performance prior to manufacture and testing.

These tools include Predictive Software Code developed in-house, Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD). Our numerical tools are used for seal design, performance optimization, special product application and troubleshooting.

In combination with an extensive test program the result is world-leading technology that keeps your equipment running longer.

API Plan 53B System

Plan 53B system

The AESSEAL® Seal Auxiliary Systems Division has established a pioneering method of developing API Plan 53B Systems.

Plan 53B systems have been viewed as an “engineering challenge” around the world, often with long lead times. The innovative modular concept permits 12 modular options to be applied to create an API 53B System for any application.

API Plan 54 Forced Oil Circulation System


PUMPPAC - API Plan 54 Forced Oil Circulation System

AESSEAL® PUMPPAC™ Systems are used when the heat dissipation from a thermosyphon system is not sufficient for the application.

API Plan 54 forced circulation system


Oil PUMPPAC System

The PP/SOU (Special Oil Unit) utilizes the same operating principle as the standard AESSEAL® PP/O1 PUMPPAC.

Pre Throat Bushing

PFR-Throat bushing for stuffing boxes and flush water management.

This throat bushing with spiral grooves and a special flow geometry reduces flush water usage and prevents solids from entering the stuffing box.

Python Heat Exchanger


Advanced Natural Convection Air Cooling

The AESSEAL® Python is an advanced air cooled heat exchanger for cooling mechanical seal barrier / buffer / flush fluids.

RDS - Split Seal


Split Seal

The RDS™ eliminates the need to remove or strip equipment for seal replacement. The unique design makes it the quickest to install two part seal currently available in the market place.

RDSX — Radially Divided Seal


A split seal solution ideal for those difficult to reach applications

The RDSX™ seal eliminates the need to remove or strip equipment for seal replacement. The self aligning rotary makes the RDSX™ one of the easiest and quickest to install split seals on the market today.
