Dosing pumps for precise dosing of chemicals and other liquids

Dosing pumps are designed to dispense chemicals and other liquids in precise quantities. This type of pump is often used in the pharmaceutical industry, for dosing paint and varnish, in the wastewater and food industries and other areas. Especially in these areas, it is important that the dosing is completely accurate, which is typically done in smaller quantities. When you use a dosing pump, it's easier to have full control over the amount, so you don't dose too much or too little.

How does a dosing pump work?

You can get dosing pumps that are either electronically controlled or using compressed air. A dosing pump works by retracting the pump's magnet so that the liquid is sucked into the pump chamber. You can compare it to a syringe with medicine, where you suck the medicine into the spray chamber by pulling back the pump. The advantage is that the non-return valve on the pump's outlet is completely closed, so no air enters the pump when the magnet is pulled back. 

When the magnet is then pushed forward again, the liquid is forced out through the pump outlet while the check valve on the pump inlet is closed. It is possible to control a dosing pump in different ways. Some dosing pumps have a knob to control the frequency of the pump strokes, while other dosing pumps are controlled using pulse signals from flow meters. In addition, you can set the dosing pump to dose with a single pump stroke rather than repeated pump strokes.

What type of dosing pump should you choose?

If you have a low-flow application that requires precise dosing of chemicals or liquids, it makes sense to use a dosing pump. For smaller volumes, capacities are typically under 50 liters per hour at a pressure of around 10 bar. But you can also get dosing pumps that can handle up to 170 m3 per hour and a pressure of 700 bar. The benefits of using a dosing pump are that you achieve precise dosing and save energy by using a pump. 

There are different types of dosing pumps for different purposes. These include acid pumps, chlorine pumps, chemical pumps, biocide dosing pumps and other types of pumps. So depending on the type of liquid you need to handle and the process the dosing pump supports, you can choose a pump that best suits your business needs. At the same time, you can customize the dosing pump by configuring it to fit the exact applications it will be connected to.

How do you operate a dosing pump?

The dosing pump is a motor-driven mechanical piston pump in chemically resistant materials. Chemical resistant materials are PP, PVDF, PVC and stainless steel. It is easy to operate a dosing pump, either using inverter control or automatic stroke length control. In addition, it is possible to get dosing pumps that can be operated via Bluetooth. This allows you to create a log file in an app that you can send via mobile or iPad to your email or save the pump configuration on your mobile device. All that is required is that your mobile device has internet access. Get professional advice on choosing a dosing pump.
