1 Mechanical Metering Pumps - MEMDOS E/DXGeneral DescriptionThe MEMDOS series is an economical line of motor driven , Mechanical diaphragm Metering Pumps . This versatile line offers two versions to meet a variety of applications. The base model, MEMDOS E, is a manually controlled version. For applications re-quiring control by an external signal, the intelligent MEMDOS DX offers state-of-the-art microprocessor control. By integrating the speed control, the MEM-DOS DX eliminates the need for the further expense of additional variable speed controllers. High quality mechanics, combined with the proven reliability of our MAGDOS series brains, brings ad-vanced technology to the Metering pump industry. There are two chassis sizes within the MEMDOS E and MEMDOS DX family. The smaller size is rated for capacities up to 42 gph. The larger size is rated for capacities up to 92 gph. Pressure ranges are avail-able to 150 psi, depending on pump capacity. Check valves are double ball or spring-loaded single ball En Stroke length control features 10:1 turndownn Capacities up to 92 gph, pressures up to 150 psigMEMDOS DXApplication Flexibilityn Up to 1400:1 turndown provides more precision in process controln Automatic or manual controln NEMA 4X enclosure protects electronics in harsh environmentsMicroprocessor Controln Integrated speed control allows for the selection of several control signals: - pulse/contact control - multiplication/division capabilities - analog mA, 0-20 mAn Remote start/stop capabilitiesn Input signal monitoring and output alarmsUser Friendlyn Touch pad and LCD displayn Self-diagnostic system for monitoring chemical feed process.
