The S200 is offered with an excellent water for injection (WFI) configuration with a built in double mechanical seal flushing arrangement. We are convinced this is the best WFI sanitary centrifugal pump on the market. We have sold hundreds of S200 pumps for WFI applications over the past 10 years and have had no issues with them. Almost all of our largest pharmaceutical customers have standardized on the S200 for WFI.

This Tuesday’s product focus post is centered on a pump technology we haven’t touched on yet- the Thermo Scientific FH [...]

To identify the best sanitary pump for the application we rely on a number of analytical tools to assist in the process, including several pump sizing programs, pressure drop calculation software, manufacturers data as well as a lot of tribal knowledge we have developed over the years.

To kick off 2014 we’ll review all of the information you can get from a motor nameplate and how that information can help you to replace or specify a new motor.

Premium efficiency motors also offer additional benefits. Because they are constructed with improved manufacturing techniques and superior materials, they usually have higher service factors, longer insulation and bearing lives, lower waste-heat output, and less vibration of which increase reliability. Most motor manufacturers also offer longer warranties for their most efficient models.

In this post we are going to take a look at two specific sanitary pump applications Holland ran into with customers in the field and how we helped them get better life out of their pump seals.

After a lot of internal discuss we have put together what we feel the key criteria to consider when making a decision on what type of base you want with your sanitary PD pump.

An alternative to electric sanitary positive displacement or centrifugal sanitary pumps are air-operated pumps, namely air operated double diaphragm pumps and piston pumps.

You now have to decide on which model, the U1 or the U2. Which is the better choice? It depends on your application. In this post we will go over the criteria we use here to determine which is the better choice.

JM motors were designed specifically for rotating equipment with rotating seals, in other words, pumps. Specifically, pumps with mechanical seals (the benefits and applications of which we’ve discussed in previous posts).

The most efficient sanitary centrifugal pumps on the market today have open impellers with partial shrouds on the back of the impeller.

Instead of getting into a great amount of detail on one particular product, this week I’m going to cover a [...]

Today we are talking about centrifugal pump curves.  Centrifugal pump curves are derived from the affinity laws, a topic we [...]

At Holland, we’ve been putting sanitary pumps into service for over 60 years. And one thing that every pump needs [...]

This blog will address the unique advantages of the Quattroflow and why we’re starting to see more and more of our high purity customers switch over to this technology.
