Engineered vs. Catalogue seals

COMPARE ENGINEERED VS. CATALOGUE SEALS

To determine weather you should custom design a mechanical seal for your product and application, or just go for a standard catalogue seal, you need to understand when to use which concept:

WORKING WITH CATALOGUE SEALS

If time or resources are limited in your product development department, it may seem advantageous to use a standard catalogue seal. This solution might allow for better control of development resources as you use what is readily available and make product adaptations inhouse. The drawback of this concept however is that you will have a seal that is not designed for  purpose and therefore does not ensure optimal performance of your product or your customers application – only a seal engineered to your specification can do this.

You may  be considering catalogue seal to pitch your products to end-users as solutions with readily available standard spare parts, which are easy to find and supplied at a low cost. However, the low cost strategy also leads to a negative impact on quality – something you are not in control of, and do not want to associate with your brand.

Some organizations do not have the strategy or resources in growing their aftermarket sales department, and therefore rely on other players in the market to supply  seals as spare parts to end-users. When this is the case we recommend using a standard catalogue seal.

WORKING WITH ENGINEERED SEALS

Roplan offers R&D, engineering and manufacturing of mechanical seals engineered to customer specifications. But, our offer doesn’t end when we deliver your mechanical seal, we want to partner with you and be your extended development department. For over 40 years we have been helping our customers with all their mechanical seal related issues. So when you develop a new product, we are there to support your internal development department and en sure the full potential of your products is achieved.

When you choose Roplan to engineer a mechanical seal to meet product and/or application specifications, the aftermarket opens up to you. Not only because the seal bears your logo, but also because the engineered seal cannot be replaced by a standard catalogue seal, designed for a different purpose, in different materials and in different physical dimensions. This in turn leads to a stable revenue over economic cyclical fluctuations, which becomes particularly noticeable during a recession, when new equipment sales decline and maintenance contracts grow.

The difference between a catalogue seal and a customer specific engineered seal is seldom visible to the the eye, the difference lies in details like the use of materials and in the internal physical design.
