Sustainable Protection Against Wear and Chemical Attack

In 2021, three years ago, Lutze was called upon by a Dutch customer, part of a global group, to solve a complex challenge. A cast iron pump housing of a macerator, which after 1.5 years of use was suffering from severe wear and low pH attack, needed better protection to extend its lifespan.

We then decided to have the pump housing fitted with a SiC casting polymer by Nomig. This intervention would certainly make the pump housing more resistant to the severe conditions in which it operated.

Now three years later, the customer contacted us again saying the grinding ring urgently needed to be replaced. This gave us the opportunity to look at the pump housing from the inside again. Thanks to the durable protective layer that was applied in 2021, the pump housing now showed only minimal wear and very little chemical attack this time. The pump housing that has now been in use for 3 years looks much better than the original untreated pump housing being in use for 1.5 years!

The grinding ring has now been replaced and the pump housing has been given a good refresh. The pump housing can now certainly last for years.

This successful collaboration shows how important it is to invest in high-quality protection solutions. In this case, the SiC treatments were each time cheaper than buying a new pump housing and therefore making the customer save more than 50% since the installation of their pump!

Through Lutze's expertise and Nomig's innovative products, the customer is assured of a longer lifespan for his pump. Thanks to the SiC casting polymer treatment of the pump housing, the customer has significantly reduced their maintenance costs while the lifespan of their pump is extended.

All the advantages of this solution at a glance:

• Extended lifespan of critical components
• Reduced wear and chemical attack
• Less maintenance and lower costs
