Chemical metering pumps are as varied and numerous as the chemicals they meter out. One kind of chemical metering pump is a peristaltic pump. A peristaltic pump is so named for the peristalsis movement it creates to push a chemical or liquid down and into something else. The peristaltic "wave" is created by the rolling mechanism you see in the machine, rolling and compressing the chemical/liquid every few seconds to every few minutes. To get a really good idea of the jobs these pumps do, here are three sub-types of peristaltic pumps.
Time-Based Dosing Pump
This is a medical-grade pump. Any time you spend time in a hospital bed and need to receive medication, you will see this sub-type of peristaltic pump. One port under the pump connects to a saline bag and/or a medication bag. The other port is connected to an IV that heads into your arm. Your doctor determines how much saline and/or how much of the medicine you receive over a specified amount of time. The pump is programmed accordingly, and you just have to lay back and let it do its job.
High Output, Variable Speed
A high output, variable speed pump is used for cleaning and sanitation. For example, you can connect these pumps to commercial washing machines so that they dispense "x" amount of detergent into each load. When connected to a commercial washing machine that may require more or less detergent, the washing machine's programming signals the pump as to the correct and applicable amount of detergent to dispense and pump into the washer as it runs.
Adjustable Drain Treatment with Built-In Timer Controller
As the name clearly suggests, this pump is meant for restaurants that have grease traps. Rather than constantly worry about grease causing back-ups and flow issues in the drain, this pump frequently flushes a chemical into and through the grease trap to dissolve large deposits of semi-solidified grease and fats. It has a built-in timer controller so that your grease trap is flushed on a regular schedule (e.g., weekly). If you find that you need your grease trap flushed more often, you only have to reset the timer programming. You can also use the pump to do a one-time flush ahead of or behind a timed flush, and then either cancel the flush or allow the flush to go on as it was programmed.
