Riding on the crest of the waves

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. 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, the MEMDOS LP pumps can also be supplied with a double-diaphragm system.

MEMDOS LA

  • Output range from 4 – 1020 l/h, up to 16 bar

  • Power supply 115 / 230 V, ± 5 %, 50/60 Hz

  • Material finishes PVC, PP, PVDF and stainless steel

  • Stroke frequency manually settable via a potentiometer

  • Release input for external start/stop

  • Analogue input 0/4 – 20 mA

  • Level input with a switching point

  • Analogue output 0/4 – 20 mA

  • Alarm relay output

  • Stroke feedback output

  • Double-diaphragm system (optional)

  • CSA and UL certified

Riding on the crest of the waves

The MEMDOS LA is equipped with a diverse range of inputs and outputs and can thus be deployed for complex dosing tasks. It can be controlled via a 0/4 – 20 mA current input and an external release input. At the same time, it indicates its current operating state via a fault output (alarm relay) and an optocoupler output (stroke feedback). The pump is fitted with a 0 – 20 mA analogue output.
The MEMDOS LA is compatible with all conventional control systems.
The pump is also fitted with a level input, can evaluate suction lines directly using a low level alarm and its large functional scope means that it can be deployed in a number of areas.

MEMDOS LB

  • Capacity range 4 – 1020 l/h, up to 16 bar

  • Power supply 115 V, 230 V or 400 V

  • Material finishes PVC, PP, PVDF and stainless steel

  • Infinitely variable stroke length from 0 – 100 %

  • A variety of three-phase and alternating current motors

  • ATEX versions are available for Zones 1 and 2

  • Also suitable for frequency converter operation

  • Double-diaphragm system (optional)

  • Automatic stroke length adjustment (optional)

Riding on the crest of the waves

The MEMDOS LB is used when the integration of the pump into controls or control circuits is required. 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. 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. On request, the MEMDOS LB pumps can also be supplied with a double-diaphragm system.
