Description

The DAB K 20/41T 0.37kW Three-Phase Single-Impeller Centrifugal Pump is a compact and reliable centrifugal pump designed for a wide range of domestic, commercial, agricultural and industrial water applications.

The K 20/41T features a robust cast-iron pump body and motor support, a single impeller and a carbon/ceramic mechanical seal. Its closed asynchronous motor is externally ventilated to provide reliable cooling during operation.

With a three-phase 230–400 V electrical supply, the K 20/41T is particularly suited to installations where a three-phase power supply is available. The pump can be installed in either a horizontal or vertical position, provided that the motor remains above the pump.

The pump is suitable for applications including water transfer, general water supply, irrigation, tank filling, water treatment systems, decanting and mixing where clean, non-aggressive and water-like liquids are required.

DAB specifies the K Single Impeller range for domestic, civil, industrial and agricultural installations, as well as decanting, mixing and irrigation applications.
