This post fill focus on limit and proximity switches, what they are, and how they are different.

Screen gaskets are great for protecting sensitive pieces of process equipment, such as spray balls, pumps, and filling needles. Contrary to popular belief, they are NOT designed to replace inline, wye, or basket strainers

So which is the better hose choice? It is really a function of your application. The cost differential between the two is not particularly significant. If you get into applications above 100 PSI, the PTFE hoses are probably preferred. If you need something light and flexible (short load cell jumpers are a good example) silicone works great.

To ensure constant, uniform flow, suction head must be kept constant. Previous posts have focused on issues like pump suction and cavitation. Today we’ll build upon this and discuss balance tanks and their application in metering and dispensing processes.

Automated stem seat valves are workhorses in the sanitary food and beverage process industries and for good reason.  They are [...]

We wanted to use this post to list the information we normally request to help get you the correct parts for your Waukesha PD pump.

This post will focus on what electropolishing is, and isn’t and why we use it in the high purity process world.

Holland has been doing research on what hose barb factors create the best unions and this post will highlight key considerations to keep in mind when selecting your next fitting.

Today, we’ll take a look at the first of three different level technologies we deal with all the time at Holland and how we can apply it, measuring pressure to determine level.

So how do you tell the difference between the metals if they are not labeled? We do positive metal identification tests (PMI) using X-ray Florescence.

Shear is defined as relative motion between adjacent layers of a moving fluid. When one layer of a fluid moves adjacently to another layer of fluid, it can begin to exhibit the deleterious effects of shear. Shear rate is defined as the measure of the extent or rate of relative motion between adjacent layers of a moving fluid. Therefore:

For one reason or another, our customers often need to adapt their process lines from sanitary tube to pipe fittings and vice versa. There are several ways to do this. We will use this post to better detail what types of fittings are commercially available to accomplish this

Measuring and accurately monitoring process conditions is essential in high purity applications. In the over sixty years Holland has spent [...]

We had a post last week that went over what a hazardous location is and how they are classified. With [...]

The sanitary mag mixer is a relatively simple device. The impeller mounts onto the weld plate on a spindle that has a bearing on it. Different manufacturers have different bearing designs, the most common is to use a hardened material as a thrust bearing. The drive unit locks to the bottom of the weld plate. When the drive rotates, its magnet locks onto the magnet in the impeller causing it to turn. Like we said, simple.
