628 EC-DU-L

Product catalog summary

Product Overview: The SP 620, 625, and 628 EC-DU-L are eccentric diaphragm pumps designed for liquid applications, including industrial, medical, laboratory, cooling, heating, and cleaning. These pumps are capable of delivering two different media simultaneously and function as both vacuum and pressure pumps. They are self-priming, leak-tight, oil-free, maintenance-free, and feature reduced vibrations, low noise, and lightweight construction.

Specifications: The pumps operate at 12 Vdc or 24 Vdc with varying free flow rates and flow rates at 15m H2O. They can achieve a maximum pressure height of over 15 m H2O and a maximum vacuum of -300 mbar. The maximum suction height when filled with water ranges from -5.5 to -6.2 m H2O. The pumps are constructed with EPDM, FKM/FFKM/PTFE materials, and feature iron core motors with ball bearings.

Performance and Construction: The pumps are designed to produce pressure above 15 mWC, although exceeding this limit is not recommended. They offer standard and optional configurations for connection ports and are customizable for specific applications without additional costs.
