Dosing pumps for precise dosing of chemicals and other liquids

Dosing pumps are designed to dose chemicals and other liquids in precise quantities. This type of pump is often used in the pharmaceutical industry, for dosing paint and varnish, and in the waste water and food industries, as well as other areas. Especially in these areas it is important that the dosing is absolutely accurate, which is typically done in small quantities. When using a dosing pump, it is easier to have full control over the quantity, so that neither too much nor too little is dosed.

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 pulling back 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 syringe chamber by pulling back the pump. The advantage is that the check valve on the pump outlet is completely closed, so no air enters the pump when the solenoid is retracted. 

When the solenoid 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 rotary knob to control the frequency of the pump strokes, while other dosing pumps are controlled by pulse signals from flow meters. In addition, you can set the dosing pump to dose only with a single pump stroke rather than repeated pump strokes.

What type of dosing pump should you choose?

If you have a low-flow task that requires precise dosing of chemicals or liquids, it makes sense to use a dosing pump. For smaller volumes, capacities of less than 50 litres per hour at a pressure of about 10 bar are typical. But you can also get dosing pumps that can handle up to 170 m3 per hour and a pressure of 700 bar. The advantages of using a dosing pump are that you get very accurate dosages and you save energy by using a pump. 

There are different types of dosing pumps for different purposes. It can be an acid pump, chlorine pump, chemical pump, pumps for biocide dosing and other types of pumps. So depending on the type of liquid you need to handle and the process the dosing pump will support, you can choose a pump that best suits your business needs. At the same time, you have the option to 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 chemical-resistant materials. Chemical resistant materials are PP, PVDF, PVC and stainless steel. It is easy to operate a dosing pump, either by inverter control or automatic stroke length control. In addition, it is possible to get dosing pumps that can be operated via Bluetooth. Then you have the option to form a log file in an app, which 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.
