Do You Have Backup Spares for your Sanitary Pumps & Valves?

July 7, 2020

I like to think of pumps as the heart of any sanitary processing system. After all, the human heart is a vital organ that essentially works as a pump for the body. But over the years, Holland Applied Technologies has noticed a recurring issue: many of our customers with pumping applications will not replace their pump components when necessary. Instead of following recommended maintenance cycles, they often wait until something breaks or fails and now a common spare part that is needed yesterday!

It is important to always have a replacement pump part readily available for your

maintenance personnel. Having replacement pump parts avoids putting major stress on maintenance personnel trying to solve the problem. It also avoids production halts which is a waste of both time and money. Pumping systems can account for a large portion of a plant’s energy usage, so the added downtime and expenditures can be significant. We all know the phrase “time is money”. Simply keeping a spare seal kit around can save major bucks.

One of the first steps we recommend when installing a new pump into a system is getting to know the recommended maintenance cycles for your specific pumps and pump parts. These maintenance cycles are most likely found in your pump’s operation and maintenance manuals.

Let us take a look at the WCB Universal 3 Series PD Pump instruction manual as an example. Waukesha recommends changing the grease and oil for the gears and bearings every 750 hours as well as a fully detailed maintenance inspection to be performed at least annually. These preventative maintenance inspections include inspection of the rotors, gears and bearings. The WCB Universal 3 Instruction Manual also contains a Maintenance Inspection Chart which details maintenance intervals for various parts of the WCB PD pump. You can quickly find a copy of this manual along with many of our other product manuals and resources within our Engineering Toolbox .

We get calls and emails regularly requesting pump parts for many of our sanitary pumps .While some customers know exactly what parts they need, others do not. If you fall into the latter category, we recommend having your pump serial number ready. The serial numbers can tell us all the information we need to get you spare parts. Can’t find a serial number? A model number, pictures, or knowing whether you bought your pump from us will certainly help our sales engineers get you the correct parts.

Today’s blog is about stressing the importance of keeping a stock of spare parts. Having a stock of spare parts is paramount to proactive maintenance. If you are wondering how often you should replace your pump components, contact a Holland Sales Engineer today to address any pump maintenance questions you may have.

Stainless Steel Finishes: Passivation vs. Electropolishing

July 7, 2020

Passivation and electropolishing are two widely used finishing operations within our industry. Not knowing their differences often leads to confusion between specification callouts and a true understanding of each process. In this blog we will briefly explain some of the differences between the two.

EP Manifold

Holland Applied Technologies offers a broad range of sanitary fabrication capabilities, including electropolishing and passivation services.

Passivation is a chemical process designed to increase the corrosion resistance of stainless steel parts. It is a non-electrolytic process typically using nitric or citric acid which removes free iron from the surface and forms an inert, protective oxide layer that in turn renders the stainless steel more rust-resistant due to the lack of iron to react with the atmosphere. During a machining processes, stainless steel parts may have imperfections from iron embedded onto the surface from the machining tool ends. These free irons on the surface should be removed to prevent a corrosive reaction between the different metals.

Parts are placed in a basket and submerged in the nitric or citric acid bath. Depending on the stainless steel alloy, the acid concentration, temperature, and time are set to effectively remove free iron and other foreign materials on the part’s surface. Passivation ultimately leaves the part clean and more corrosion resistant due to the passive oxide “film” layer but does not change the aesthetics of the part.

Passivation processes in the pharmaceutical industry are generally regulated by the ASTM, specifically ASTM guideline ASTM A967. The most common type of passivation used throughout the biotech industry is citric acid passivation because it is a low hazard cleaning agent and is biodegradable.

Electropolishing is an electrochemical process that provides a variety of benefits, including deburring, micro finish improvement, and improved corrosion resistance by eliminating embedded contaminants and surface imperfections. Through the electropolishing process, surface material is removed by anodic dissolution using electrical current passing through electrolytic solution.

In the electropolishing process, a part is submerged in a chemical bath treated with electricity, making it shed a uniform layer of surface material. This strips away contaminants and burrs while smoothing out imperfections like microscopic cracks and jagged edges. The part is left visibly bright and shiny, and it retains these characteristics even in highly corrosive environments.

Electropolishing is used in the pharmaceutical industry to improve surface uniformity, cleanability, and prevents attack from aggressive chemicals by rendering parts passive. While small surface finish improvements are achieved, electropolishing is meant to complement, not replace, mechanical polishing. At Holland, we work with subcontractors for our electropolishing that polish in accordance with ASTM B912 and ASME BPE specifications.

So what is the difference between electropolishing and passivation? Both are methods for increasing corrosion resistance, but their similarities end there. Passivation does not change the surface appearance nor does it offer a microfinish improvement. Additionally, passivation is not an effective method for removing surfaces that have been welded with oxide heat effect scale or heat treated.

Oftentimes both electropolishing and passivation are called out together on specifications. The proper process then is to electropolish to utilize the surface removal and polishing advantages of electropolishing and then follow it up with passivation to remove any possible free irons on the surface which were exposed during electropolishing.

Holland Applied Technologies has offered electropolishing and passivation services for quite some time. For any questions or guidance with your sanitary surface finish application, please contact a Holland Sales Engineer.
