The series consists of 13 sizes with 1 up to a maximum of 18 stages -- horizontal (series MKH, MKE) or vertical (series MKV) centrifugal pumps with closed impellers.

Balance of axial thrust by an independent relief of the impellers. Remaining axial thrusts are absorbed by sufficiently proportioned roller-bearings.

Pumps with pressures exceeding 40 bars (series MKE) are additionally equipped with a balance drum.

For an optimal adjusting to the operating point the diameters of the impeller blades will be corrected when required.
