Piston diaphragm dosing pumps

Piston diaphragm dosing pumps stand for precision and independence from pressure, making them the ideal dosing devices for precise mixing tasks. Their ability to set dosing quantities in proportion to the stroke length enables precise setting of even the smallest quantities. Moreover, externally controllable drive motors allow flexible adjustment of the total dosing quantity from 5 % to 100 % without changing the mixing ratio. These features make piston diaphragm pumps a reliable choice for demanding industrial dosing tasks.

MEMDOS KMS/ZKMS


Powerhouse in a modular system

The MEMDOS KMS/ZKMS was developed in accordance with the modular principle. This offers the advantage that – depending on the problem – you can combine various pump elements and thus obtain a dosing pump that is optimally tailored to your needs.

Versatile and flexible

During the development of the MEMDOS KMS, a focus was placed on ensuring the following advantages for the user:

Ease of installation

  • quick diaphragm change possible
  • no zero-point correction with dismantling of the piston flange required

High flexibility

  • The rational structure requires only a minimum of spare parts storage
  • The addition of a second dosing unit to the drive with an identical or different capacity range produces a double head pump, the MEMDOS ZKMS
  • Thanks to its symmetrical form, the piston flange can be installed on the left-hand or right-hand side of the simple pump, ensuring an economical and compact system design
  • Due to the installation of only four stud bolts, the dosing pump can be converted from manual stroke adjustment to electrical stroke adjustment
  • For operation, motors with a multi-range voltage (220 – 240/380 – 420 V, 50 Hz; 440 – 480 V, 60 Hz) and a high protection class (IP55) and insulation class (F) are used. Special motors (ATEX) are available on request
  • TÜV-checked pressure relief valves are integrated in all pumps to prevent damage to the pump and the periphery.The pressure relief valves are selected to match the pump capacity and the desired maximum pressure in the system
MEMDOS KMS LB/LA

Extrem strapazierfähig

Die MEMDOS KMS LB/LA vereint die Leckagefreiheit der Membrandosierpumpen mit der Präzision der Kolbendosierpumpen und garantiert somit eine zuverlässige Dosierung. 

Die MEMDOS KMS LB/LA ist eine strapazierfähige Pumpe mit hydraulisch ausgelenkter Membrane. Das vertikale Hydrauliksystem ist wartungsarm und benötigt keine komplizierten Entlüftungs- oder Nachfüllmechanismen. Ein integriertes Überdruckventil in der Hydraulikeinheit öffnet bei Überlastung und sorgt damit für Sicherheit. Die vorgespannte, rohrförmige Membrane gleicht ungleichmäßige Ansaugbedingungen selbständig aus. Die Dosierpumpe erreicht eine Ansaughöhe von bis zu 5 m. Über einen Steuerschieber kann die Dosiermenge im Betrieb oder Stillstand komfortabel reguliert werden ohne dabei die Hublänge zu verändern. Dies geschieht entweder manuell mithilfe der Hublängeneinstellung bzw. mithilfe eines Potentiometers oder automatisch mit einem 0/4 – 20 mA-Signal über einen Frequenzumrichter.
