Metering pump is a device used to control the flow rate of a fluid, it moves precise volume of liquid in a specified time period. These pumps are commonly used for a wide range of possible applications but are very popular for purposes of wastewater management as well as industrial use of any kind which requires the transfer of a certain liquids and chemicals in certain volume of fluids.

Metering pumps come in all shapes and sizes, here at WRS we have different models as well as chemical dosing pumps which can be either Air, Motor or Selenoid driven chemical dosing metering pumps. When choosing a metering pump, there are many considerations to tick off to get the right one, although being certain of your specific requirements definitely helps.
Below we’ll discuss some important criteria to consider when choosing a metering pump.

Basics of a Metering Pump

Flow rate is an essential part of the metering pump functions to understand as it greatly affects the result of the chemical dispersion. The flow rate is indispensable for precision when you are dispersing chemicals either for coagulation (often used in wastewater to gather solids in one place) or simply successful filtration and killing off germs.

Transfer pumps that simply squirt out chemicals are significantly different from chemical metering pumps with the latter being a more sensible purchase, especially for manufacturing plants and industrial uses. Preventing fluid slip due to any faulty internal mechanism is very important for various reasons, one being pumping inaccuracies.

Determine Your Specific Metering Needs

Choosing a metering pump type and model depends greatly on your specific requirements more so than anything else. It is helpful to make a list of all the tasks that the metering pump will need to perform, and then you can correlate that to specific add-on components.

The pressure, temperature, and speed of flow needed is also an essential factor to measure, and the chemical dosing pumps manufacturers will guide you on different pumps after these requirements are communicated to them. You can always contact WRS experts for friendly and professional advice when you require chemical dosing pumps as we cater for diverse set of industries.

Get Your Application Requirements Right

Metering pumps are built around specificity and calculation which is why application data consisting of elements such as the motor data, average temperatures, pressure of output needed is vital to get right. The following is a basic checklist to make sure you’ve considered all the factors.

  • Check inlet as well as discharge pressure. Additional pressure (if expected) will require extra and sometimes specialized components and metering system accessories for the pump.
  • What is the temperature of the liquid?
  • Are there any solids that need to be filtered out or coagulated (change to a solid or semi-solid state)?
  • What is the nature of the fluid being treated? (There are different types and levels of chemicals with distinct compounds, wastewater and industrial water).
  • Measure the flow rate that will be metered.

Ancillary Concerns

As you will agree that with any system built by various different components, the metering pump does not simply carry out the required tasks on its own, and with different requirements come various ancillary components. These components can be anything from pressure relief valves, isolation valves, strainers, and so on. Different valves ideally should also have various settings so that the correct input / output result can be obtained.

Installation & Expert Advice is The Key for Getting The Right Metering Pump

Imagine your car radiator just stopped working, would you just buy the first car radiator you see on a car part seller website? Of course not, this is similar scenario when it comes to metering pumps.

It isn’t good enough to just buy a pump from any old place, or, using metering pumps others may have found useful for their own particular application. Because having the right expert advice and installation to have a complete system in place so that everything works properly requires more than just a metering pump. You will need to have an expert install it as manuals aren’t always very comprehensive or easy to do it yourself. For many metering pump applications (to protect them from outside elements) it may be necessary to build storage cabins to elongate their useful life.
