Instrumentation & Pumps

If you need help choosing the right instruments and pumps for your wastewater treatment needs or are looking for a simpler, more efficient system to replace your current equipment, you’ve come to the right place. We will ask about your specific application, including your treatment process and physical installation. This will help our experienced engineers determine the right system for you.

Equipment Ordering

Ordering measurement instrumentation or pumping equipment can often become a confusing process.  Murphy & Dickey’s customer service team is trained to help you through that process.  We double-check your application with the engineering recommendations to ensure that all the details that will make your system work are included.  Next, we coordinate with the equipment manufacturers to make sure your measurement and pumping solutions are correct and delivered when you need them.

Company History

Murphy & Dickey was started by Ralph Murphy and Diamond Dickey in 1943, in downtown Chicago.  Originally, the company provided electrical testing and process recording equipment to local manufacturing and power generation facilities.  In the 1970’s, under the direction of Jim Fell and Mark Potter, the company moved to the Western Suburbs.  For the next 25 years, M&D specialized in instrumentation for water monitoring, gas analysis, and temperature control. In the 1990’s, pumps, mixers, and water treatment equipment were added.  In 1999, Tom Fitzpatrick and Mark Ostrowski took over M&D with a new team, continuing our company tradition of treating others as we want to be treated.

Today, the M&D team continues to solve applications for instruments and pumps for water treatment in industrial and municipal facilities.  Our engineers are also trained in the application of fire and gas detection systems, used many industrial, municipal and commercial locations.

How Suppliers Measure Up

Working with a variety of instrumentation and pumping equipment helps us look at suppliers the same way our clients look at us. We have found four “key” categories of questions for evaluating our suppliers that may help you.

A.B.C.D. Keys


  • When can I get it?
  • How about replacement parts?


  • Will they support it?
  • Do their “experts” speak our language?
  • Do they stand behind the product?


  • Which is best for our budget?

Analytical instrument manufacturers fall into two categories:

  • Chemical & Reagent Manufacturers provide instrumentation as delivery systems for their products. Think about the low-cost printer that makes 20-30 times the price of the device on replacement ink cartridges.
  • Equipment Developers work on the measurement technology. Reagents and supplies are secondary for use in support of the instrument. Many new instruments operate without consumables.


  • Does it work?
  • How long will the sensor last?
  • How often does this system need maintenance?

Asking good questions at the start of the project can help us to solve your application challenges.  There are many good manufacturers of instrumentation and pumps today, and our goal is to provide the right solution for you.
