We are very quick to respond to inquiries, reach out to us with any questions or alternatives to these systems you’d like to know about.

Common Custom Specifications

We have noticed an increase in inquiries for our feed systems when it comes to “one off” custom applications. It is common for us to receive a call that goes something like, “Hey, I was looking at your feed systems and I like the idea of getting something similar to a model TE501 but…

  • “we need a stainless steel tank”
  • “we need a larger pump”
  • “we need it to be on two separate platforms”
  • “we want to double up everything, and to have it all on one skid”

And so on and so on. Sometimes we’re even receiving inquiries asking, “I need a system put together with no tank and mixer, but rather 4 pumps working together via a switch board”.

“Can you do this?” – Yes we can!

*VIDEO

This is a 1:30 minute video giving a brief overview of a chemical feed system of ours. You may notice this system in the video won’t technically be found in our literature. This is because the customer needed us to jump from a JN series pump to an MF series pump, as well as find them a 30 gallon stainless steel tank. Done and Done!

 

Conclusion

This video shows how our simple and clean standard feed system design can be tweaked and reengineered to perfectly fit your application.

If you have seen anything here that is close to a perfect fit for serving an application of yours, but it just needs some slight variations, give us a call (574) 295-4292 and we’ll see what we can do.

What is Chemical Metering and When is it Needed?

Chemical metering is the act of adding chemicals into another process at a repeatable and consistent rate. The consistent and repeatable aspect is what distinguishes this process from any other type of fluid transfer process; there are hundreds of applications requiring the transfer of liquid from point A to B, none require the consistency and accuracy at the level chemical metering does.

Understanding when it’s best to use a Diaphragm metering pump vs. other chemical pumps

When you have an application that requires you to meter liquids into other processes at a finite and accurate rate, a metering pump is well suited for this. Even more specifically, when you need that finite amount of liquid to be dosed at a consistent, repeatable rate, diaphragm metering pumps are perfect. For mechanically actuated diaphragm metering pumps, this usually means the operating pressure is less than 500 PSI, for hydraulically actuated diaphragm metering pumps the pressures can go much higher, often up to 1,000-2,000 PSI.

Madden Metering Pump continues to thrive 50 years of use and a negligent shipment back to the factory

To start off 2018, we had an interesting repair pump situation arise. A Madden metering pump sent back in for repair that was over 54 years old. This diaphragm metering pump has been in operation since October 16, 1964. The majority of its time has been spent dosing diatomaceous earth slurry for the drinking water at Wells College in Aurora, NY. It just 
recently got sent in for repair to semi retire as the backup pump.

Chemical pumps designed for pumping polymers and alums

Polymers and alums (or aluminum sulfates) are often used in wastewater treatment processes. These solutions act as flocculants and coagulants to help separate impurities from waste water.

Flocculating, or coagulating, are similar processes that treat wastewater by helping bring together dissolved and suspended solids and other impurities in water to form larger aggregates for easy separation. After the aggregates form, they will settle to the bottom for easy removal by either scraping the formed “scum” away or utilizing an inline filter.

Automatically Changing a Chemical Metering Pump’s Output using VFD’s

This blog will go over the simplest ways to change the flow rate on a Madden metering pump. To start, all Madden chemical metering pumps are designed with a manual stroke length adjustment built right into the pump. This allows for a very linear turndown of the pump’s output or flowrate and it is quite simple. A knob and dial scale on top of the pump allow you to turn down the ouput at a 10:1 ratio of your pump model’s max capacity.

(*VIDEO) How the Manual Flow Rate Adjustment Works on a Madden Pump

Applications that call for metering, dosing, or the injecting of chemicals also call for accuracy no matter the conditions or settings the pump may face. The need for accuracy in these applications is simply a given, and there are two reasons accuracy goes hand in hand with injecting chemicals. The first reason is that precise amounts of a chemical could be needed to achieve the goal of the application.

What all can affect flow rates in Metering Pumps?

High quality metering pumps are precise when they arrive from the factory. Pressures, temperatures, viscosities, and other factors will not affect the ability of a quality metering pump to be precise. In other words, these factors will not affect the pump’s ability to produce the same output repeatedly for a long time. A quality metering pump’s output should not fluctuate while in operation.
