Motor-driven diaphragm dosing pumps

The Memdos LB and LP series are offered in a broad capacity range. Due to numerous versions of dosing heads and valves, combined with a wide range of materials for the dosing head, an even greater consistency and application range is covered. The performance ranges from 0 – 4 up to 0 – 150 l/h for the first size, and 0 – 110 up to 0 to 1010 l/h for the second size. The maximum permitted pressure, depending on the size, is between 4 and 16 bar. Thanks to the sturdy tappet drive with manual or automatic capacity adjustment, the conveyed media such as acids, lyes, coagulants and flocculants are dosed reliably and precisely.

On request, both dosing pumps can also be supplied with a double-diaphragm system. Thus, uncontrolled leakage of medium is prevented even if the dosing diaphragm ruptures.

For constant dosing without a controller, the motor of Memdos LB is directly connected to the terminal box. A great variety of three-phase and single-phase motors is available for this purpose. To adapt the dosing capacity, either the stroke length can be adjusted mechanically or the speed of the three-phase motor can be regulated by means of a separate frequency converter.

The Memdos LP is used when the integration of the pump into controls or control circuits is required. For integration into demanding automation networks, a version with an Ethernet-based MODBUS interface is available.

The Memdos LP doesn‘t just impress with its elegant design; the graphical display with a multi-language menu as well as the dosing pump‘s operation using the integrated keyboard simplifies its use. If required, the dosing pump can be controlled via an analogue or pulse input. To react to any variations in the control circuit, the pump has many additional functions; stroke remote reporting, external operation consent, level monitoring, fault reporting via a relay as well as diaphragm rupture monitoring.
