When considering different positive displacement pumps for your chemical addition process, often times you will be choosing between a diaphragm type metering pump and a plunger type metering pump. Both pumps are designed to produce accurate and repeatable outputs. This is an important feature for any metering pump as dosing the exact amount of chemical needed can be vital to the application in creating a new product as well as saving money by avoiding waste.
Yearly chemical costs for some applications can be millions of dollars, you don’t want to settle for just any metering pump to dose these chemicals. So let’s take a look at when a diaphragm metering pump is the best design for a metering application.For flow rates above 360 GPH and pressures above 300 PSI, a plunger type metering pump is likely going to be your best option. These pumps’ design allows them to hit very high flow rates and pressures. However, this same design also limits the packed plunger metering pump significantly when it comes to flexibility. So unless you are indeed dealing with high pressures, don’t settle on a packed plunger type pump.
Diaphragm type chemical dosing pumps can ultimately be a money saver
Most packed plunger type metering pumps use a steel solution head and steel plunger. If the chemical you need to dose is corrosive to steel, that immediately eliminates a packed plunger metering pump. And now begins the costly and time consuming process of finding other pumps and manufacturers to handle your other chemical addition jobs.
There are hundreds and hundreds of chemicals being used in industrial processes for hundreds of different applications. A diaphragm metering pump design like Madden makes, allows for flexibility by offering wetted end materials to handle any chemical addition processes.
Often times, you don’t need just one metering pump to dose one chemical into one application, but rather several metering pumps pumping several different chemicals into several applications, if not more! Having a product line like Madden Pump’s chemical metering pump covering all your applications allows for much easier employee training with equipment, ability to keep common spares on hand for emergencies, only needing to go through one trusted rep/distributor, and so on.
How is Madden able to offer so much flexibility to handle any chemical?
The answer is pretty simple, we have Neoprene, Hypalon, Viton, and Teflon diaphragms available. These four materials can handle 99% of any chemical pumping application you bring to us. Along with diaphragm options, you can also choose between Polypropylene, PVC, Teflon, and 316 stainless steel solution heads as well. Madden Pump can mix and match materials to design the most cost effective and durable chemical dosing pump for your application.
