DDA, DDC, DDE PUMPS
Digital Dosing solutions (SMART Digital, DME, DDI) set new standards for liquid chemicals dosage and accuracy.
Digital Dosing solutions (SMART Digital, DME, DDI) set new standards for liquid chemicals dosage and accuracy. The operator can easily install and set the pump to pump exactly the amount of liquid required by the process thanks to a unique drive and flow control concept. The pump setting is displayed in ml/h, l/h or gph and the operating mode is easily identified by icons. The DMH range of mechanical hydraulic dosing pumps is the preferred choice for industrial and complex tasks. The DMH series is a series of extremely powerful and robust pumps for applications requiring a large dosing range and high pressure capacity.
The presented dosing pumps are designed for dosing chemicals in the following applications, among others:
- drinking water treatment,
- wastewater treatment,
- preparation of cooling water,
- washing facilities,
- treatment of service water,
- chemical industry.
Properties and adventages:
- accurate and easy adjustment,
- unique technology,
- a small number of options will cover all needs,
- full impulse control,
- impulse rate control,
- dose control with internal timer,
- analogue control 0/4-20 mA,
