If you have a residential wastewater treatment system or an agricultural farm, their daily operations can result in high levels of chemicals being consumed. The chemicals are usually delivered in large amounts, which is why injection measures have to be put in place to ensure only the required amounts are being used. For this reason, you will find it necessary to invest in a chemical metering pump for injecting the correct amounts of chemicals in your agricultural, wastewater treatment and other similar processes. However, since there is quite a variety of chemical metering pumps available, selecting one can be somewhat challenging. For this reason, here are a few tips to help you pick the best chemical metering pump for your application.
Consider the Size/Operating Capacity of the Pump
Sizing is critical when it comes to choosing chemical metering pumps and the flow rate requirements of your specific agricultural or wastewater treatment process will help you find the correct size. Oversizing or under sizing a chemical metering pump will affect its accuracy, which is something you want to avoid if precise amounts of chemicals are to be injected. Once you have determined the flow rate of your materials, you have to be very keen on the pump size or capacity you select. As a rule of the thumb, the maximum flow rate you expect should be relatively less than the pump's operating capacity. For instance, the maximum flow rate could be eighty per cent of the metering pump's operating capacity. Doing this is important because it ensures in case any extra capacity is needed in future, you won't have to worry about looking for another pump with higher capacity.
Look at the Line or System Pressure at the Point of Chemical Injection
Just like the size, the pressure rating of the chemical metering pump is of great significance when it comes to choosing one. If the pressure at the point of chemical injection is higher than the pressure being discharged by the pump, very little amounts of chemical will be injected. Sometimes no chemical may be injected at all. On the other hand, if the pump's discharge pressure is relatively higher, larger amounts of chemical will be injected. In either case, the pump won't be functioning efficiently so pay attention to the pressure ratings.
Evaluate the Chemical Resistance of the Pump's Material
The chemicals being injected can sometimes be of very high concentration. For this reason, the material of the metering pump you choose should be able to resist any form of corrosion or deterioration. For instance, if the chemicals being injected are composed mainly of acids, you may want to go for a stainless steel chemical metering pump that will resist the corrosive action of the acids.Share

Hello. My name is Renee. Welcome to my sanitation blog. As an event planner, I have hired toilets for a range of events, and I've learnt what's important. In this blog, I am going to write helpful useful tips related to exorcising dirt and unpleasant odours from your life with an emphasis on toilets, rubbish bins and such like. I tend to organise concerts, but I've worked with a range of events. When I'm not working, I love to kick back and relax by working on creative projects. Writing blogs and sewing are my current favourites. When I just need to zone out, I binge watch old British mystery series. Thanks for reading.
