Functions

DMS

Capacity control, DMS

The electronically controlled synchronous motor of the

DMS offers similar advantages of the DME pumps. As

shown in the figure below, the suction and discharge

stroke speeds are constant while the stroke frequency

varies according to the capacity set.

The sinusoidal movement of the diaphragm offers the

following advantages:

• The pump is always operating at full stroke length,

irrespective of the capacity set, for optimum accu-

racy, priming and suction.

• A capacity range of 1:100 for each pump size.

• Reduction of pressure surges, preventing mechani-

cal stress on diaphragm, tubes, connections and

other dosing parts exposed to leakage and wear.

• The installation is less affected by long suction and

discharge lines.

• Easier dosing of highly viscous and gas-containing

liquids.
