Description

The DAB K 45/50 T is a high-quality twin-impeller centrifugal pump designed to provide efficient and reliable water pressurisation in domestic, commercial, agricultural and industrial installations.

The two impellers provide increased pressure performance compared with a conventional single-impeller pump, making this pump particularly suitable for applications where a combination of good flow rate and higher delivery pressure is required.

The pump is manufactured with a cast-iron pump body and motor support, while the impellers are constructed from durable technopolymer. A stainless-steel drive shaft and carbon/ceramic mechanical seal provide dependable operation and good resistance to normal wear.

The enclosed asynchronous motor is externally ventilated for effective cooling. The three-phase version should be installed with appropriate motor overload protection in accordance with applicable electrical regulations.
