302 SA-D Vibrating Diaphragm Pumps

Product catalog summary

Product Overview: The SP 302 SA and SP 402 SA are vibrating armature pumps designed for gas and air applications. These pumps are characterized by being oil-free, maintenance-free, and having reduced vibrations and low noise, contributing to a very long lifetime. They are suitable for laboratory equipment and industrial applications.

Specifications: The pumps are available in various configurations for vacuum and pressure applications. They offer different performance metrics based on the configuration, such as free flow rates and maximum pressure or vacuum levels. The pumps are available in both 230 V (50 Hz) and 120 V (60 Hz) versions.

Performance: The pneumatic performance includes free flow rates ranging from 3.0 to 4.5 l/min, with specific flow rates at 100 mbar and -100 mbar. Maximum pressure can reach up to 400 mbar, and maximum vacuum levels can reach -250 mbar, depending on the model.

Construction: The pump body is made of aluminum, with CR diaphragms and seals. The pumps are equipped with electromagnetic motors, consuming between 4.0 W and 4.5 W of power. Optional configurations include different inlet and outlet setups, such as foam filters and silencers.

Additional Information: The document notes that specifications are subject to change without notice and are provided for preliminary information only. Custom versions of the pumps are available upon request to meet special requirements.
