Grundfos Metering and Dosing Pumps: DDA, SMART Dosing, DMX, DMH

Product Description

The stepper motor technology provides continuous dosing - resulting in smooth control in setpoint applications. Built in autodearation and bubble detection prevents pump cavitation and ensures reliable chemical feed under the harshest circumstances.

The Smart Digital DDA-C-E Dosing Pumps set new standards in liquid chemical handling and accuracy. With 3000:1 turndown and +/- 1% accuracy the DA can be scaled to meet the widest range of flow rates in one model.

A large LCD screen with visible pump status colours allows the operator to know, at a glance, the pump run status. Easy to install and operate with its unique drive-and-flow-control management concept. The setting of the pump is displayed in ml/h, l/h or gph, and the operation mode is easily identified by means of icons.
The DMH mechanical hydraulic dosing pump range is the preferred choice for industrial and complex tasks. The DMH range is a series of extremely strong, robust pumps for applications where a substantial dosing range and high-pressure capabilities are required.


The DDI 222 series offers a quiet solution to your mechanical dosing needs. Dosing heads and valves are available in a variety of materials while noise from operation is kept to a minimum, reaching just 45dB (A) regardless of model.

DMX mechanical diaphragm pumps are part of a highly versatile dosing line suitable for a wide variety of applications. DMX models are available in a wide flow range and dosing head size.
