The SPF25 in-phase linear pump is a new type of high-precision, micro-volume filling pump. Through electronic control, it solves the industry pain point of decreased accuracy after continuous filling in traditional pumps. It also features a compact structure, high integration, and simple control. With dedicated piping, it can be operated with one hand. The pump head body is made of SUS304 with a corrosion-resistant surface treatment, allowing for disinfection and cleaning with hydrogen peroxide, ozone, alcohol, and epoxide. The liquid inside the working pipe does not come into contact with the pump body, ensuring no contamination.
