AESSEAL Mechanical Seals are used in a wide range of pumps and rotating equipment worldwide to prevent liquids and gases escaping into the environment. We manufacture mechanical seal types to suit all industries and our investment in modular design means that we provide the best on-time delivery performance in the industry.

The AESSEAL® range of seals, seal support systems and bearing protectors are all designed to improve pump reliability and reduce maintenance costs.Seacoast Supply maintains a large inventory of AESSEAL products.

Cartridge mechanical seal construction is a proven reliability improvement. The seals are pre-assembled at the factory, pressure tested and shipped as a unit, leading to improved performance as errors due to incorrect installation are reduced. Cartridge construction eliminates the need to measure and set spring compression, and having a mechanical seal pre-assembled means that the seal faces are protected from damage during installation.

A double or dual mechanical seal consists of two independent seals mounted within a seal chamber outside the pump, which is flushed with an independent supply. This makes them ideal for sealing hazardous liquids, liquids with abrasives or liquids that are corrosive, as the seal faces only see clean lubrication greatly increasing mechanical seal life.

AESSEAL® double mechanical seals have independent seal-face designs, to enhance safe containment of process fluid in the event of damage to any individual sealing element.

This means that no matter how well designed your mechanical seal or bearing systems are, without a reliable Seal Support System there is still the possibility of your mechanical seal failing. The innovative and reliable Seal Support System Range at AESSEAL® gives customers the confidence to remove this root cause of mechanical seal failure.

AESSEAL® offer a range of bearing protection devices suitable for most applications. The innovative LabTecta® and MagTecta™ products include patented features that deliver the best possible bearing housing sealing solution for your motor, pump, plummer block, gear boxes or steam turbine.

Our technicians are familiar with the wide variety of seal families, materials and their applications. Through each stage of the repair / rebuilding process the seal is tested to exceed manufacturer’s specifications.

Slurry mechanical seal as a simple "pre-set cartridge seal" that requires no measuring or special tools for assembly into the equipment housing easily disassembled and rebuilt either in the field or plant workshop, without the need of any special tools.

Sealing many products in various types of fluid handling equipment WITHOUT any type of flush thereby eliminating product dilution or contamination from barrier fluids or gases. (Some services a flush has been shown to prolong seal life).

Optimum sealing performance while running totally submerged, but to also withstand intermittent dry running situations, and still maintain a positive seal when the fluid returns to the seal area.

Design features have minimized the number of parts facilitating ease of assembly and installation. Fewer o-rings than other slurry seals reducing the number of possible leak paths.

Minimum amount of spares for inventory, thereby minimizing inventory carry costs and freeing up shelf space. (Traditional mechanical seals are sold in 1/8 in. increments. One PANACEAL compared to eight traditional seals).

No seal hang-up due to product crystallization on the atmospheric side of the rotary assembly. (Product crystallization is a normal result of face lubrication).
