BDC Laboratories’ PD-0250 portable oscillating fluid pump / pulse duplicator provides a compact, purely oscillating flow source for applications requiring a dynamic flow environment. When coupled with valved technologies, the PD-0250 is a reliable driver that facilitates highly repeatable opening and closing dynamics of test articles. The PD-0250 utilizes a diaphragm-based drive mechanism that results in very low maintenance and highly reliability. Applications for this fluid oscillating pump include: physician training systems, production qualification systems and sales demonstration models.
