Chemical dosing pumps inject a precise amount of substance into a flow of water or gas. These pumps have a wide variety of applications. For instance, they can be used in water treatment plants to inject chlorine or in food industries to inject sweeteners. The pumps are also used in the agriculture and mining industries.  

Below is a comprehensive guide on how chemical dosing pumps work and the various considerations you should make when buying a chemical dosing pump.

How Do Chemical Dosing Pumps Work? 

The chemical dosing pump contains a tank that holds the substance to be injected into the liquid or gas line. A control system allows you to adjust the amount of liquid you need in the line. The chemical dosing pump contains a foot valve at the point of entry and discharge to regulate the amount of substance injected.

Buying a Chemical Dosing Pump

Below is a short guide to help you purchase a chemical dosing pump. 

1. Manufacturer

Purchase the pump from a reputable manufacturer. Conduct some research to ascertain the durability of various pumps. Internet reviews and testimonials can be credible sources of such information. Preferably, choose a company that provides warranties and after-sales services such as free shipping and servicing.

2. Intended Use

The pump must be fit for its intended application. For example, chemicals such as hydrofluoric acid can corrode the pump. If you would want to inject hot liquids, the pump's components should be temperature resistant. On the other hand, the pump should be lined with a non-adhesive layer if you will inject sticky materials. 

Check the pump's flow rate. It is the amount of substance it can inject per minute. Typically, the pump should have the ability to inject more product than you need. If you need the elements injected at a specific pressure, consult the manufacturer to know if the pump meets the required standards.

3. Maintenance Schedule

Similar to any other machine, dosing pumps are prone to wear after years of use. Some pumps have a warning system that alerts you if the pump has a leakage. Check the pump for cracks, low hydraulic fluid and worn out valves. Read the user manual to know when you should change the various components. Preferably, you should ask a professional to inspect the pump annually. He or she can identify worn-out parts and give advice on suitable repairs and preventative maintenance procedures.

A chemical dosing pump can ease operations at your water treatment facility, food processing plant, agricultural and mining operations. When buying a pump, examine the manufacturing company, its intended use and maintenance schedule.
