Grundfos pump. In addition to its simple operability, it achieves precise injection across a wide flow range of 60 to 940 liters per hour.
The adoption of stepper motors and EC drives optimizes the control of stroke speed, achieving extremely high precision. The duration of each discharge stroke varies according to the flow rate setting. Although the suction stroke time is always constant, it can be extended using the cavitation prevention function, allowing for a wide range of needs to be met. In this way, the suction is always performed at full stroke. This enables smooth pumping of liquids that release gas and achieves continuous injection with minimal pulsation, which is crucial for injection systems that require long suction lines. The DME pump series, as a compact digital injection device, allows for more precise injection than ever before.

basic information
■Accuracy and Easy Setup The pump accurately dispenses the required liquid volume for each application with just installation and simple setup. You can not only view the set values directly on the screen but also check pulses and batches. The operating mode can be easily identified by icons. ■Turn Down Ratio 1:800 Achieves adaptability and accuracy with a turn down ratio ten times that of conventional devices. The suction stroke is turned down to 75%, 50%, or 25% of the maximum speed, ensuring optimal priming and dispensing even for difficult-to-handle liquids. ■Unique Technology With unique technology, it injects accurately and with minimal pulsation even for high-viscosity or easily vaporized liquids. Instead of adjusting based on conventional stroke length, the dispensing volume is controlled by the motor speed during the dispensing stroke, while the suction stroke speed remains constant, ensuring optimal and uniform mixing conditions. ■Fieldbus Communication Allows for the collection of quality control, preventive maintenance, performance data, and condition data. ■Overload Protection Function The built-in overload protection function monitors the pump's back pressure to prevent excessive pressure loads. ■Variety of Material Options Pump head materials can be selected from stainless steel, PVDF, and cost-effective PP that does not impact the environment.
