The SYB-type filter press feed pump is a next-generation filtration pump developed by our company, specifically designed for various filter press operating conditions. Featuring negative pressure technology and a dual-stage semi-open impeller design, it achieves a maximum pressure of 1.6 MPa, making it ideal for feeding high-pressure filter presses. This pump can efficiently handle weakly corrosive materials, hard particles, and substances with poor filtration properties over extended periods, as well as other applications requiring high-pressure, non-clogging, and leak-proof material conveyance. It is widely used in pharmaceuticals, wastewater treatment, papermaking, and nanomaterial industries.
