MEMDOS LB, LA, LP | MEMDOS MR/ZMR
Reliable dosing of chemicals
The motor-drive diaphragm dosing pump MEMDOS stands for robust quality and reliable dosing results.
The wide range of different motors available means that it can be deployed in nearly any area.
We provide pumps for a range of contexts ranging from simple applications to integration in complex plant systems. The MEMDOS series also contains a number of different versions which can be deployed in explosive atmospheres.
Our complete range of diaphragm dosing pumps
MEMDOS LP
MEMDOS LP - technology that makes waves!The MEMDOS LP is used when the pump needs to be integrated into control systems or control loops. A version with an Ethernet-based MODBUS interface is available for integration into sophisticated automation networks. Thanks to a robust tappet drive with manual or automatic capacity adjustment, the pumped media, e.g. acids, alkalis, precipitants and flocculants, are dosed reliably and accurately. The MEMDOS LP is also available with a double diaphragm system on request.

MEMDOS LB
MEMDOS LB - technology that makes waves!
The MEMDOS LB is a motorised diaphragm dosing pump that is used when no control system is required for constant dosing. Thanks to a robust tappet drive with manual or automatic power adjustment, the pumped media, e.g. acids, alkalis, precipitants and flocculants, are dosed reliably and accurately.
To adjust the dosing capacity, the stroke length can be adjusted mechanically or the speed of the three-phase motor can be controlled via a separate frequency converter. The MEMDOS LB is also available with a double diaphragm system on request.
Features & advantages
Capacity range 4 - 1020 l/h, up to 16 bar
Power supply 120 V, 230 V or 400 V
Material versions PVC, PP, PVDF and stainless steel
Stroke length infinitely adjustable from 0 - 100
Wide range of three-phase and alternating current motors
ATEX versions for zones 1 and 2 possible
Suitable for frequency converter operation
Double diaphragm system (optional)
Automatic stroke length adjustment (optional)
