Description

The DAB K 11/500 M is a robust single-impeller centrifugal pump designed for domestic, civil, industrial and agricultural water systems, as well as applications such as water transfer, decanting, mixing and irrigation.

The pump is equipped with a 2.2 kW single-phase motor and is designed for demanding water-transfer applications where reliable flow and pressure performance are required.

The K 11/500 M features a cast-iron pump body and motor support, a cast-iron impeller, carbon/ceramic mechanical seal and a durable construction suitable for continuous-duty water applications.

According to DAB’s catalogue, the K 11/500 M delivers heads from approximately 24.5 m at zero flow to 6.5 m at 30 m³/h, with a maximum operating pressure of 8 bar (800 kPa).
