The Style 57 design serves to keep the sealing faces in contact and positively transmits the drive evenly 360° around the full circumference of the rotary face. This is accomplished by the special spring design, which provides an interference fit. The compression spring is wound either right or left hand depending on shaft rotation.

Conventional pump stuffing boxes were originally designed to accommodate packing materials. Over the years mechanical seals edged out packing as a preferred sealing method, however stuffing boxes essentially remained the same. This situation posed complications for the effective operation of mechanical seals including installation issues, potential damage from abrasive product, and poor dispersion of seal-generated heat.

The ANSI Standard ASME B73.1 Specifications for Horizontal End Suction Centrifugal Pumps for Chemical Process includes specifications to improve the reliability and safety of the B73.1 pump design. One major specification focuses on cylindrical (big bore) and self-venting (tapered bore) seal chambers. Both of these seal chamber designs address the issues that plagued conventional pump chambers by providing additional radial clearance for mechanical seal operation and for increased liquid circulation around the seal, enabling the seal to run cooler and longer.

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.

Cartridge seals are a modern alternative designed to eliminate common causes of component seal failure. Check pump unit for defects before installing a cartridge seal to avoid damage to seal parts.

Single cartridge or double cartridge seals are self-contained units comprised of a shaft sleeve, seal, and gland plate. Cartridge seals are fitted onto the pump shaft as a single unit with no further fitting or assembly required.

Cartridge mechanical seals for centrifugal pumps are built for high performance and easy installation. These fully self-contained mechanical seals are pre-assembled, factory pressure tested, and shipped as a one-piece unit. Installation often requires little more than removing a few bolts and/or set screws, inserting the seal unit itself, and replacing the fasteners.

This design helps reduce errors caused by incorrect installation or improper assembly, and eliminates the need for users to measure and set spring compression. And, with all parts contained inside a durable housing, seal faces and other components are protected from possible damage during shipping, handling, and installation.

With barrier fluid pressure higher than product pressure, the AST80M prevents leakage of hazardous fluids into the environment. The barrier fluid provides lubrication for the seal in top-entry mixers.

With unpressurized buffer fluid, the outboard seal runs “at idle” as a standby seal. If the inboard seal fails, the outboard seal provides primary protection, eliminating unscheduled shutdown of batch processes.

Mechanical seals are an integral part of machines that deal with hydraulics, pumps being an excellent example. Since there are different types of seals available, however, choosing the one that would work best for your pump can get tricky.

Cost is a major part of any maintenance project. Cartridge-type mechanical seals are much more expensive than component mechanical seals when comparing the two options.

While both types of seals offer reliable performance once installed correctly, the degree of installation complexity varies significantly based on your choice. Component mechanical seals must be assembled before installation and require spring tension adjustment. This is a task best reserved for skilled technicians. On the contrary, cartridge mechanical seals come assembled. Hence, the installation process is simple and leaves less room for errors.

Cartridge mechanical seals are easy to install when you have the right make and model. However, they still lack compatibility with a broad range of pumps available in the market. Since component mechanical seals have been in the industry for the longest, they are available for almost all types of shafts and pumps.

Mechanical seals (conventional and cartridge) offer an alternative to packing. Over the years, advancements made to face materials and elastomer selections have played an important role in mechanical seals becoming a more superior option.

Conventional seals are not without their challenges, however.Conventional seals require the operator to set and align the seal on the shaft or sleeve of the pump, a task that is difficult to say the least. This can increase margin for error resulting in premature failure. With reducing maintenance costs and downtime becoming highly valued assets in manufacturing, cartridge seals are quickly becoming the seal of choice. Continue reading to learn about cartridge seals, installation, and some things to remember.

Untrained operators and installation errors are some of the reasons seals fail prematurely. To help operators overcome the fitting and installation problems associated with conventional seals, cartridge seals were developed. Cartridge seals are self-contained units consisting of a shaft sleeve, seal, and gland plate. The design of the cartridge seal works to eliminate common causes of seal failure from installation errors, and because the seal is presented on its own shaft sleeve, any damage that might be caused by a conventional seal to the pump unit is eliminated.

It"s pretty simple actually: Slide the cartridge seal over the shaft as the pump is being built, align the gland ports, finish building the pump, evenly tighten the gland, tighten the collar set screws, and remove the spacers. Easy, right? The cartridge unit is fitted onto the pump shaft as a whole, pre-built assembly, which requires no further fitting adjustments (when compared to conventional seal installation procedures). The most common mistake we see is mechanics attaching the cartridge seal to the seal chamber BEFORE installing it on the pump - wrong!

Since the cartridge seal does not require the usual setting measurements and adjustments, maintenance costs are lowered and seal installation errors are minimized leading to more optimal seal life.

When using cartridge seals, make sure the unit is in good operating condition to minimize any future problems, such as a leak after the seal installation. Check the following:

And, most importantly, cartridge seals offer a level of standardization no matter what OEM machine is being sealed. When switching from conventional to cartridge, a drop off in seal performance should NOT be expected.
