Robco"s Mechanical Seal Division manufactures, distributes and customizes mechanical seals, as well as being a repair facility for virtually any mechanical seal brand, utilizing the latest technology and state-of-the-art manufacturing equipment. Robco’s seal designs are customer driven to provide the best possible solutions to sealing problems.

Robco will repair: Borg-Warner, Chesterton, John Crane, Durametallic, EG&G, Flex-A-seal, Flexibox, Flowserve, Garlock, Pac-Seal, U.S. Seal, and virtually any other brand.

Mechanical seals are used everywhere liquids and gases are transferred through rotating equipment. Robco’s seals and packing are the first step to efficiently control leakage and reduce operation costs.

The ideal seal for alumina applications, specifically designed to operate in this challenging environment, the Robco DRYTEK seal will provide maintenance-free operation at least five to twenty times longer than your average alumina screw conveyor seal.

•Better abrasion resistance  •Dry-seal, no lubricant required  •Sealing components rotate with the shaft, maintaining an airtight seal  •Adapts to axial and radial movements of the shaft  •Available in C.E.M.A. and METRIC standard shaft sizes.

Double balanced cartridge seal for pumps, agitators and mixers that prevents the leakage of toxic, hazardous, corrosive and costly fluids to the atmosphere.

Robco uses specialized equipment to ensure that rebuilt seals operate equal to brand new, with mechanical seal manufacturing and rebuilding experience dating back to 1978, servicing petrochemical, pulp & paper, steel, mining, waste water, utilities, boilers and more...

We rebuild all major brands at competitive prices with premium quality parts that meet all OEM specifications. We offer a free estimate and failure analysis. Rebuild outlay normally varies from a third to half the cost of a new seal, so lower your inventory value and reduce your overall operations cost.

By centralizing your repairs: Robco rebuilds all major brands in one location, simply complete our Seal Repair Form to be enclosed along with your seal shipment and we’ll take care of the rest, returning your seal looking and working like new. Robco tags all rebuilt seals for future rebuild identification, tracking seal life and failure patterns.

Mechanical seals are critical components in centrifugal pump systems. These devices preserve the integrity of the pump systems by preventing fluid leaks and keeping contaminants out. Mechanical seal systems are used on various seal designs to detect leakage, control the seal environment and lubricate secondary seals.

Depending on the pump type and the process variables, there are various mechanical seal types to choose from. Each seal variant has its unique design and characteristics which make it suitable for a specific application. MES has years of experience with industrial mechanical seals and support systems, making us an authority in this area.

Mechanical seal types vary in design, arrangement, and how they disperse the hydraulic forces acting at their faces. The most common seal types include the following:

Balanced mechanical seal arrangements refer to a system where the forces acting at the seal faces are balanced. As a result of the lower face loading, there is more even lubrication of the seal faces and longer seal life. Learn about our mechanical seal lubrication systems today.

Balanced mechanical seals are particularly suited to higher operating pressures, typically above 200 PSIG. They are also a good choice when handling liquids with low lubricity and higher volatility.

Unbalanced mechanical seal types are commonly employed as a more economical option to the more complex balance seal. Unbalanced seals may also exhibit less product leakage due to tighter control of the face film, but as a result can exhibit much lower mean time between failure. Unbalanced seals are not recommended for high pressure or most hydrocarbon applications.

Pusher seals utilize one or multiple springs to maintain seal closing forces. The springs can be in the rotating or stationary element of the mechanical seal. Pusher type seals can provide sealing at very high pressures but have a drawback due to the elastomer under the primary seal face that can be subjected to wear as the face moves along the shaft/sleeve during operation.

Non-pusher seals utilize a metal or elastomeric bellows to maintain seal closing forces. These seals are ideally suited to dirty and high temperature applications. Bellows seals are limited to medium/lower pressure applications.

Conventional seals are typically lower cost and often installed on general service equipment. These seals require higher operator skill to service as they installed as individual components.

Cartridge type mechanical seals incorporate all of the seal elements into a single assembly. This dramatically reduces the potential for assembly error and the time require for seal replacements. Learn more about the difference between cartridge and non-cartridge mechanical seals today.

When deciding on the type of seal system for a centrifugal pump, operators must choose according to their unique application. Failure to select the proper seal type can lead to loss of pump integrity, breakdowns and costly repairs. To avoid these undesirable results, all operators must consider the following factors before deciding.

The amount of pressure exerted at a mechanical seal’s faces has a significant effect on its performance. If a pump is to be operated at low pressures, an unbalanced mechanical seal will be suitable. However, in conditions where higher pressures are anticipated, balanced seals will prove a more reliable solution.

Balanced mechanical seals perform better than their unbalanced counterparts in conditions where the operating temperatures are higher than normal. Heat sensitive components are better preserved in balanced mechanical seals compared to other seal types.

As it goes for all types of machinery, operator safety is the top priority. The use of double mechanical seals in centrifugal pumps provides additional protection as they have increased sealing capacity and are generally more reliable.
