200 EC-LC Eccentric Diaphragm Pumps

Product catalog summary

Product Overview: The document details the features and applications of eccentric diaphragm pumps, specifically models SP 200 EC, SP 250 EC, and SP 270 EC. These pumps are designed for air and gas applications, functioning as either vacuum or pressure pumps. They are electrically driven and available in 5, 9, and 12-volt DC versions.

Key Features:

Diaphragm micro pump suitable for air and gas.
Oil-free and maintenance-free operation.
Minimal current consumption and virtually leak-tight.
Compact, lightweight, and low noise with reduced vibrations.

Applications:

Air sampling, gas measurement, and metering.
Portable gas detectors and safety devices.
Patient monitoring and analyzers.
Exhaust gas analysis and pneumatics.
Pipetting devices and fuel cells.

Technical Specifications:

Operating voltages range from 3 Vdc to 12 Vdc.
Pneumatic performance varies with free flow rates between 500 to 820 ml/min and maximum pressure up to 680 mbar.
Maximum vacuum capability is up to -600 mbar.
Motor types include standard iron core and optional brushless versions.
Weight ranges from 17.1g to 30.3g depending on the model.

Construction and Options:

Pump heads and diaphragms are available in standard and optional materials like EPDM, FKM, and Silicone.
Optional port positions and mounting clamps are available for noise and vibration reduction.

Installation Recommendations:

Use padded adhesive tape, Velcro, or foam-lined boxes to secure the pump and reduce noise and vibration.
