DULCO® flex DF2a Series Suitable for dispensing, metering and general transfer applications the DF2a peristaltic pump from Prominent provide a cost effective, accurate option for various applications. The DF2a is virtually silent in operation and simple to operate and install. Non siphoning pumping method prevents back flow and promotes accuracy. A rotor inside the pump squeezes the tube pushing the chemical in the direction of flow. No valves or moving parts in contact with the chemical helps maintain purity and improves reliability. Accuracy and long service are also maintained by using spring loaded rollers to keep a consistent pressure on the hose. Features and Benefits Self-priming against a max pressure of 1.5 bar
