550 EC

Product catalog summary

Product Overview: The SP 500 EC and SP 550 EC are eccentric diaphragm pumps designed for air and gas applications. They can function as either vacuum or pressure pumps and are driven by an electric motor. These pumps are available in various voltage options (4.5, 6, 9, and 12 V DC) and are characterized by minimal current consumption, oil-free and maintenance-free operation, reduced vibrations, low noise, and a virtually leak-tight design. They are lightweight and compact, making them suitable for portable applications.

Applications: These pumps are versatile and can be used in gas sniffers, gas measurement and metering, portable gas detectors for safety devices, patient monitoring, personal gas detectors, fuel cells, exhaust gas analyzers, pneumatics, pipetting devices, and consumer instruments.

Technical Specifications: The pumps offer free flow rates ranging from 1700 to 1900 ml/min, with varying performance at different pressures and vacuums. The maximum pressure ranges from 300 to 450 mbar, and the maximum vacuum ranges from -330 to -450 mbar. The pumps are equipped with standard and optional components such as EPDM, FKM, Silicone, FFKM, PTFE diaphragms, and valves. They feature double ball bearings and brushless motors for enhanced durability.

Performance Curves: The document includes performance curves illustrating the flow rates at different pressures for various voltage configurations. These curves are essential for understanding the pump's performance under different operating conditions.

Customization: The document notes that customized versions of these pumps can be developed for specific applications without additional costs, encouraging users to contact the manufacturer for tailored solutions.
