General DescriptionMEMDOS MN
The MEMDOS MN series is the result of a consistent, ongoing development of proven technology and the use of modern plastics.
Performance
Valves - Priming and discharge valves are designed as double-ball valves. For metering chemicals with a viscosity higher than approximately. 400 mPas spring-loaded single-ball valves are recommended.
Separation chamber - The diaphragm flange between metering head and gearbox is designed as separation chamber. In the case of diaphragm rupture resulting from wear the leakage is directed downwards by means of a drainage pipe.
Drive - With metering rates of 3 l/h up to 39 l/h the MEMDOS MN leakproof diaphragm metering pump has a wide range of application.
The MEMDOS MN is available as single metering pump with the metering head mounted on the right-hand side.
Materials of Construction
Standard materials for the metering heads are rigid PVC, PVDF and stainless steel. Other materials are available upon request.
Features
- A three-phase sectional motor provides the electrical drive. AC operation is also possible.
- In the case of this sectional motor the conventional motor end plates are replaced by the pump base and the gearbox. This gives the MEMDOS MN a compact form.
- The gearing, consisting of a single-stage worm gear, the gearing components, as well as the bearing, are lifetime lubricated.
- The discharge stroke is carried out by an eccentric actuating the diaphragm by means of a spring-loaded tappet. The suction stroke is effected by spring return. Stroke adjustment can be carried out either manually or electrically (ATE).
- For batch processes the pump can be equipped with an inductive detector for the eccentric shaft which is available upon request.
