Product catalog summary

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

Specifications: The pumps are available in various configurations for vacuum only, pressure only, or both. They come with different outlet and inlet configurations such as silencer nozzles and foam filters. The pumps operate at 230 V (50 Hz) and 120 V (60 Hz) with different article numbers for each configuration.

Pneumatic Performance: The free flow rate ranges from 3.0 to 4.5 l/min depending on the model. Maximum pressure can reach up to 400 mbar, while maximum vacuum is -250 mbar. Performance varies with different configurations optimized for either pressure or vacuum.

Motor and Power Consumption: The pumps use electromagnetic motors with power consumption ranging from 4.0 W to 4.5 W. They are constructed with EPDM diaphragms and CR valves.

Additional Features: The pumps can be equipped with optional features such as potentiometers and on/off switches. They are lightweight, with a standard weight of 850 grams.

Performance Curves: The document includes performance curves illustrating the flow rates at various pressures and vacuums for different models and configurations.
