Product catalog summary

Product Overview
The SP 620 and SP 622 EC-BL-DU-L are eccentric diaphragm pumps designed for liquid applications such as water. These pumps are suitable for industrial, medical, laboratory, cooling, heating, cleaning, and analytical applications. They are capable of delivering two different media simultaneously and function as both vacuum and pressure pumps. Key features include self-priming, leak-tight design, minimal current consumption, oil-free and maintenance-free operation, reduced vibrations, low noise, and lightweight construction.
